Effect of suspension training on neuromuscular function, postural control, and knee kinematics in anterior cruciate ligament reconstruction patients

BACKGROUND Suspension training(SET)is a method of neuromuscular training that enables the body to carry out active training under unstable support through a suspension therapy system.However,there have been few reports in the literature on the application of SET to anterior cruciate ligament reconstruction(ACLR)patients.It is not clear what aspects of the patient's function are improved after SET.AIM To investigate the effect of SET on the neuromuscular function,postural control,and knee kinematics of patients after ACLR surgery.METHODS Forty participants were randomized to an SET group or a control group.The SET group subjects participated in a SET protocol over 6 wk.The control group subjects participated in a traditional training protocol over 6 wk.Isokinetic muscle strength of the quadriceps and hamstrings,static and dynamic posture stability test,and relative translation of the injured knee were assessed before and after training.RESULTS The relative peak torque of the quadriceps and hamstrings in both groups increased significantly(P<0.001),and the SET group increased by a higher percentage than those in the control group(quadriceps:P=0.004;hamstrings:P=0.011).After training,both groups showed significant improvements in static and dynamic posture stability(P<0.01),and the SET group had a greater change than the control group(P<0.05).No significant improvement on the relative translation of the injured knee was observed after training in either group(P>0.05).CONCLUSION Our findings show that SET promotes great responses in quadriceps and hamstring muscle strength and balance function in ACLR patients.

Complex knee injuries treated in acute phase: Long-term results using Ligament Augmentation and Reconstruction System artificial ligament

AIM To present the long-term results of complex knee injuries, treated early using the Ligament Augmentation and Reconstruction System(LARS) artificial ligament to reconstruct posterior cruciate ligament(PCL).METHODS From September 1997 to June 2010, thirty-eight complex knee injuries were treated, where early arthroscopic PCL reconstructions were undergone, using the LARS(Surgical Implants and Devices, Arc-sur-Tille, France) artificial ligament. Exclusion criteria were: Late(> 4 wk) reconstruction, open technique, isolated PCL reconstruction, knee degenerative disease, combinedfracture or vascular injury and use of allograft or autograft for PCL reconstruction. Clinical and functional outcomes were assessed with IKDC Subjective Knee Form, KOS-ADLS questionnaire, Lysholm scale and SF-12 Health Survey. Posterior displacement(PD) was measured with the Telos Stress Device. RESULTS Seven patients were excluded; two because of coexisting knee osteoarthritis and the remaining five because of failure to attend the final follow-up. The sample consisted of 31 patients with mean age at the time of reconstruction 33.2 ± 12.5 years(range 17-61). The postoperative follow-up was on average 9.27 ± 4.27 years(range 5-18). The mean average IKDC and KOS scores were 79.32 ± 17.1 and 88.1 ± 12.47% respectively. Average PD was 3.61 ± 2.15 mm compared to 0.91 ± 1.17 mm in the uninjured knees(one with grade 1+ and two with grade 2 +). Dial test was found positive in one patient, whereas the quadriceps active drawer test was positive in three patients. None was tested positive on the reverse-pivot shift test. The range of motion(ROM) was normal in thirty knees, in comparison with the contralateral one. There was no extension deficit. Osteoarthritic changes were found in three knees(9.6%).CONCLUSION Early treatment of complex knee injuries, using LARS artificial ligament for PCL reconstruction sufficiently reduces posterior tibia displacement and provides satisfactory long-term functional outcomes.

Recurrent cyclops lesion after primary anterior cruciate ligament reconstruction using bone tendon bone allograft:A case report

BACKGROUND Cyclops lesions are a known complication of anterior cruciate ligament(ACL)reconstruction,with symptomatic cyclops syndrome occurring in up to 11%of surgeries.Recurrent cyclops lesions have been rarely documented;this case study documents the successful treatment of a recurrent cyclops lesion.CASE SUMMARY A 28-year-old female presented following a non-contact injury to the right knee.Workup and clinical exam revealed an ACL tear,and arthroscopic reconstruction was performed.Two years later a cyclops lesion was discovered and removed via arthroscopic synovectomy.Seven months postoperatively,the patient presented with pain,stiffness,and difficulty achieving terminal extension.A smaller recurrent cyclops lesion was diagnosed,and a repeat synovectomy was performed.The patient recovered fully.CONCLUSION To the best of our knowledge,this is the first documented case of recurrent cyclops lesion after bone-patellar tendon-bone allograft ACL reconstruction presenting as cyclops syndrome.

Five Strand Hamstring Tendon Autograft for Anterior Cruciate Ligament Reconstruction Provides No Benefit over the Gold Standard Four Strand Repair for Anterior Stability of the Knee: A Prospective Cohort Study

The Four-Strand Hamstring Tendon Autograft has been long established as the gold standard for surgical reconstruction of the Anterior Cruciate Ligament. Some studies have suggested wider grafts, such as a Five-Strand hamstring graft, may provide greater strength and a larger scaffold for incorporation of the graft into the bone tunnels, leading to greater postoperative anterior stability of the knee. 28 (n = 18 Four-Strand and n = 10 Five-Strand) patients with planned ACL reconstructive surgery by a single surgeon were recruited for this study. The KT-1000 Arthrometer (MED metric, CA, USA) was used to quantify AP translation in the subjects’ knees before (T0) and after surgery at 6 (T1) and 12 (T2) weeks. At 12 weeks there was significantly higher (p = 0.01) mean anterior laxity on Maximum Manual Test in the Five- Strand group (9.1 ± 1.7 mm) than the Four Strand Group (6.9 ± 2.3 mm). Further, there were significantly higher mean side-to-side differences (p = 0.01) on Maximum Manual Test in the Five-Strand cohort (5.1 ± 3.5 mm) compared to the Four-Strand cohort (1.9 ± 2.2 mm). A significantly larger positive mean change in anterior laxity (p = 0.02) from 6 - 12 weeks was evident in the Five-Strand group (1.4 ± 0.9) than the Four-Strand group (-0.3 ± 1.9 mm). No significant correlations were seen between graft widths and measures of anterior stability on KT-1000. This study illustrated that there was no benefit to using a Five-Strand Hamstring Tendon Autograft when compared to the gold standard Four-Strand Repair specifically with regards to anterior stability of the knee.

Anatomy of the anterolateral ligament of the knee joint

Despite remarkable improvements in clinical outcomes after anterior cruciate ligament reconstruction,the residual rotational instability of knee joints remains a major concern.The anterolateral ligament(ALL)has recently gained attention as a distinct ligamentous structure on the anterolateral aspect of the knee joint.Numerous studies investigated the anatomy,function,and biomechanics of ALL to establish its potential role as a stabilizer for anterolateral rotational instability.However,controversies regarding its existence,prevalence,and femoral and tibial insertions need to be addressed.According to a recent consensus,ALL exists as a distinct ligamentous structure on the anterolateral aspect of the knee joint,with some anatomic variations.The aim of this article was to review the updated anatomy of ALL and present the most accepted findings among the existing controversies.Generally,ALL originates slightly proximal and posterior to the lateral epicondyle of the distal femur and has an anteroinferior course toward the tibial insertion between the tip of the fibular head and Gerdy’s tubercle below the lateral tibial plateau.

Anterior cruciate ligament reconstruction using a double bundle hamstring autograft configuration in patients under 30 years

BACKGROUND Anterior cruciate ligament reconstruction(ACLR)has a high incidence of re-tear in younger patients.Despite comparable functional outcomes,the incidence of retear using single and double bundle ACLR methods has not been well reported.AIM To hypothesize that double bundle hamstring ACLR has a lower graft rupture rate compared with single bundle hamstring ACLR grafts in young patients.METHODS One hundred and twelve patients<30 years of age at the time of primary double bundle ACLR were eligible for study participation.91(81.3%)could be contacted,with a mean age of 20.4 years(range 13-29)and mean post-operative follow-up time of 59 mo(range 25-107).Telephone questionnaires evaluated the incidence(and timing)of subsequent re-tear and contralateral ACL tear,further surgeries,incidence and time to return to sport,and patient satisfaction.RESULTS Of the 91 patients,there were 6(6.6%,95%CI:1.4-11.7)ACL graft re-ruptures,with a mean time to re-rupture of 28 mo(range 12-84).Fourteen patients(15.4%)experienced a contralateral ACL rupture and 14 patients(15.4%)required further surgery to their ipsilateral knee.fifty patients(54.9%)returned to pre-injury level of sport.Of those<20 years(n=45),4 patients(8.9%,95%CI:0.4-17.3)experienced a re-rupture,with mean time to re-injury 15 mo(range 12-24).Comparative analysis with existing literature and revealed a non-significant Chisquared statistic of 2.348(P=0.125).CONCLUSION A trend existed toward lower graft rupture rates in young patients undergoing double bundle ACLR utilizing a hamstring autograft,compared with rates reported after single bundle ACLR.

In vitro study of knee stability after two-band two-tunnel posterior cruciate ligament reconstruction

To compare the ability of three different reconstruction procedures in restoring the posterior displacement of tibia and the posterior stability of the knee joint from 0° to 120°flexion. Methods ： Three posterior cruciate ligaments （PCL） reconstruction procedures were performed, namely two-band two-tunnel reconstruction, one-band anterior tunnel reconstruction and one-band posterior tunnel reconstruction. The posterior displacement of the tibia in relation to the femur was measured when a 200N posterior force was applied. Results： Within the flexion range of 0° to 30°, the displacement in the one-band posterior tunnel reconstruction showed little difference from that of an intact knee （P〉0.05）. But when the flexion exceeded 30°, especially when it exceeded 60°, the displacement in oneband posterior tunnel reconstruction was much greater than that of an intact knee （P〈0.01）. In two-band two-tunnel reconstruction and one-band anterior tunnel reconstruction, the displacement was approximately the same as that of an intact knee ranging from 0° to 120° （P〉0.05）, while a slight over-restriction might be found at some angles. Conclusions： Two-band reconstruction could effectively restrict the posterior displacement of the tibia and restore anterior, posterior stability of the knee joint within its full range of flexion. One-band anterior tunnel reconstruction also could maintain the posterior stability of the knee, while the result of one-band posterior tunnel reconstruction is the most unsatisfactory.

Overview of the anterolateral complex of the knee

In the last few years,much more information on the anterolateral complex of the knee has become available.It has now been demonstrated how it works in conjunction with the anterior cruciate ligament(ACL)controlling anterolateral rotatory laxity.Biomechanical studies have shown that the anterolateral complex(ALC)has a role as a secondary stabilizer to the ACL in opposing anterior tibial translation and internal tibial rotation.It is of utmost importance that surgeons comprehend the intricate anatomy of the entire anterolateral aspect of the knee.Although most studies have only focused on the anterolateral ligament(ALL),the ALC of the knee consists of a functional unit formed by the layers of the iliotibial band combined with the anterolateral joint capsule.Considerable interest has also been given to imaging evaluation using magnetic resonance and several studies have targeted the evaluation of the ALC in the setting of ACL injury.Results are inconsistent with a lack of association between magnetic resonance imaging evidence of injury and clinical findings.Isolated ACL reconstruction may not always reestablish knee rotatory stability in patients with associated ALC injury.In such cases,additional procedures,such as anterolateral reconstruction or lateral tenodesis,may be indicated.There are several techniques available for ALL reconstruction.Graft options include the iliotibial band,gracilis or semitendinosus tendon autograft,or allograft.

Anterolateral complex of the knee: State of the art

Rotatory instability of the knee represents the main reason for failure and poor clinical outcomes regarding anterior cruciate ligament(ACL)reconstruction techniques.It is now clear that the anterolateral complex(ALC)of the knee possesses a fundamental role,in association with the ACL,in controlling internal rotation.Over the past decade,ever since the anterolateral ligament has been identified and described as a distinct structure,there has been a renewed interest in the scientific community about the whole ALC:Lateral extra-articular tenodesis have made a comeback in association with ACL reconstructions to improve functional outcomes,reducing the risks of graft failure and associated injuries.Modern ACL reconstruction surgery must therefore investigate residual instability and proceed,when necessary,to extra-articular techniques,whether functional tenodesis or anatomical reconstruction.This review aims to investigate the latest anatomical and histological descriptions,and the role in rotational control and knee biomechanics of the ALC and its components.The diagnostic tools for its identification,different reconstruction techniques,and possible surgical indications are described..In addition,clinical and functional results available in the literature are reported.

Anatomical study of the anterolateral and posteromedial bundles of the posterior cruciate ligament for double-bundle reconstruction using the quadruple bone-tunnel technique

Background Several techniques have been described for posterior cruciate ligament （PCL） reconstruction. However, double-bundle PCL reconstruction using the quadruple bone-tunnel technique has been seldom reported. The current study investigated this technique, focusing on the anatomy of the femoral and tibial insertions of the anterolateral （AL） and posteromedial （PM） bundles of the PCL. Methods Twenty-two fresh, healthy adult cadaveric knees were dissected and measured. The PCL was divided into the AL bundle and PM bundle at the insertion footprint. The insertion footprints of the AL and PM bundles, their location, size, and the clock positions were measured and described. Results On the femur, the clock position of the footprint of the AL bundle was 11：21＋0：23 （left） or 0：39＋0：23 （right）, and the PM bundle was 9：50＋0：18 （left） or 2：10＋0：18 （right）, with the knee flexed at 90 degrees. The distances from the center of the femoral insertions of the AL and PM bundles to the anterior cartilage margins of the medial femoral condyle were （7.79＋1.22） mm and （8.36＋1.63） mm, respectively. On the tibia, the vertical distances from the center of the tibial insertions of the AL and PM bundles to the tibial articular surface were （3.25＋1.20） mm and （6.91＋1.57） mm, respectively. Conclusions These results have led to a better definition of the anatomy of the AL and PM bundle footprint of the PCL. The technique of double-bundle PCL reconstruction using quadruple bone-tunnel is feasible. Application of these data during PCL reconstruction using the quadruple bone-tunnel technique may help optimize knee stability.

Anterior cruciate ligament reconstruction in a 75 years old man： a case report with review of literature

Anterior cruciate ligament （ACL） reconstruction is usually recommended for young patients. Several recent articles have however reported comparable outcomes of ACL reconstruction between youth and patients in fourth or fifth age group. But in the literature there are not many reports about ACL reconstruction in patients over 70 years old. We report a case of a successful arthroscopic ACL reconstruction （using single bundle quadrupled hamstring graft） in an active 75-year-old medical practitioner. Successful outcome after ACL reconstruction can be achieved in selected older patients; chronological age is no barrier.

Posttraumatic incarceration of medial collateral ligament into knee joint with anterior cruciate ligament injury

Medial collateral ligament of the knee is an important coronal stabiliser and often injured in isolation or as combination of injuries. The article reports a case of incarcerated medial collateral ligament （MCL） injury in combination with anterior cruciate ligament （ACL） injury in 20 year old male who presented to us 4 weeks after injury. Clinical examination and MRI was correlated to complete ACL tear with torn distal MCL and incarceration into the joint. Patient was taken up for ACL hamstring graft reconstruction with mini-arthrotomy and repair of the torn MCL. Patient was followed up with dedicated rehabilitation protocol with good functional results. At one year follow-up, patient exhibited full range of motion with negative Lachman, Pivot shift and valgus stress tests. This article highlights the rare pattern of MCL tear and also reviews the literature on this pattern of injury.

Current practice variations in the management of anterior cruciate ligament injuries in Croatia

AIM: To investigate current preferences and opinions on the diagnosis, treatment and rehabilitation of patients with anterior cruciate ligament(ACL) injury in Croatia. METHODS: The survey was conducted using a questionnaire which was sent by e-mail to all 189 members of the Croatian Orthopaedic and Traumatology Association. Only respondents who had performed at least one ACL reconstruction during 2011 were asked to fill out the questionnaire. RESULTS: Thirty nine surgeons responded to the survey. Nearly all participants(95%) used semitendinosus/gracilis tendon autograft for reconstruction and only 5% used bone-patellar tendon-bone autograft. No other graft type had been used. The accessory anteromedial portal was preferred over the transtibial approach(67% vs 33%). Suspensory fixation was the most common graft fixation method(62%) for the femoral side, followed by the cross-pin(33%) and bioabsorbable interference screw(5%). Almost all respondents(97%) used a bioabsorbable interference screw for tibial side graft fixation. CONCLUSION: The results show that ACL reconstruction surgery in Croatia is in step with the recommendations from latest world literature.

Multiple-ligament injured knee

Objective： To explore the clinical characteristic of the multiple-ligament injured knee and evaluate the protocol, technique and outcome of treatment for the multiple-ligament injured knee. Methods： From October 2001 to March 2005, 9 knees with combined anterior cruciate ligament （ACL） and posterior cruciate ligament （PCL） tears in 9 patients were identified with clinical and arthroscopic examinations. Of them, 5 knees were combined with ruptures of posteromedial corner （PMC） and medial collateral ligament （MCL）, 4 with disruptions of posterolateral corner （ PLC ）, 2 with popliteal vascular injuries and 1 with peroneal nerve injuries. Six patients were hospitalized in acute phase of trauma, 2 received repairs of popliteal artery and 4 had repairs of PMC and MCL. Reconstructions of ACL and PCL with autografts under arthroscope were performed in all patients at 4 to 10 weeks after trauma, including reconstruction of PLC with the posterior haft of biceps femoris tendon tenodesis in 4 patients and reconstructions of PMC and MCL with femoral fascia in 1 patient. Results： No severe complications occurred at early stage after operation in the 9 patients. All of them were followed up for 10-39 months with an average of 23. 00 months±9.46 months. Lysholm score was 70-95 with an average of 85.00±8.29. International Knee Documentation Committee （IKDC） score was from severely abnormal （Grade D ） in 9 knees at initial examination to normal （Grade A） in 2 knees, nearly normal （Grade B） in 6 knees and abnormal in 1 knee at the last follow-up. Of the 9 patients, 7 returned to the same activity level before injury and 2 were under the level. Conclusions： The multiple-ligament injured knee with severe instability is usually combined with other important structure damages. Therefore, careful assessment and treatment of the combined injuries are essential. Reconstructions of ACL and PCL under arthroscope, combined with repairs or reconstructions of the extraarticular ligaments simultaneously or in stages, have advantage of minimal trauma in surgery and satisfactory outcome.

Longitudinal Analysis of Inter-Limb Coordination Before and After Anterior Cruciate Ligament Injury: The JUMP-ACL Study

Purpose Inter-limb coordination may provide insight into why patients with anterior cruciate ligament reconstructive sur-gery(ACLR)have an increased risk for future injury and osteoarthritis.The purpose of this study was to compare inter-limb coordination prior-to anterior cruciate ligament(ACL)injury and following ACLR.Methods Unilateral lower extremity biomechanics during a double-leg jump landing were collected prior-to ACL injury(baseline)and after ACLR,rehabilitation,and return to physical activity(follow-up).Sixty-nine participants were included in this analysis:31 participants suffered an ACL injury since baseline:12 injured the leg tested at baseline[ACLR-injured leg(ACLR-INJ),n=12]and 19 injured the leg that was not tested at baseline[ACLR-uninjured leg(ACLR-UNINJ)n=19];38 participants served as matched controls.Inter-limb coordination-calculated as the mean coupling angle-between the hip and knee were measured in the respective leg of each defined group and compared amongst groups at baseline and follow-up.Results We observed no significant change in sagittal or frontal plane inter-limb coordination amongst groups or across time(P>0.05).A significant decrease in inter-limb coordination in the transverse plane from baseline and follow-up was observed but limited to the ACLR-INJ group(P=0.016).Conclusion The primary finding of this study is that inter-limb coordination between the hip and knee in the sagittal and frontal plane is unchanged by ACL injury and ACLR.This may help explain previous observations of changes in kinemat-ics at both the hip and knee in this population.Our observation of alterations in the transverse plane should be interpreted with caution,but may provide additional evidence for potential mechanisms that lead to the development of osteoarthritis in ACLR patients.

镜下前交叉韧带重建联合固定平台单髁置换术的早中期临床疗效观察

目的 探讨单髁置换手术(unicompartmental knee arthroplasty, UKA)联合前交叉韧带重建手术(anterior cruciate ligament reconstruction, ACLR)对单间室膝骨关节炎(unicompartmental knee osteoarthritis, UKOA)合并前交叉韧带缺失(anterior cruciate ligament deficient, ACLD)患者的早期临床疗效结果。方法 选取2018年1月至2022年6月广西中医药大学附属桂林市中医医院采用同期UKA联合ACLR治疗的UKOA合并ACLD的12例患者进行回顾性研究。评估术前和末次随访的VAS、IKDC、Lysholm评分,并随访观察并发症及翻修的发生情况。结果 所有患者随访6~55个月,平均随访(24.58±10.48)个月。所有患者的平均住院时间为(13.67±6.20)d,平均出血量为(43.33±39.44)mL,平均切口长度为(9.25±0.43)cm。末次随访时的VAS评分较术前明显降低(P<0.05);Lysholm评分平均为(67.17±22.96)分、IKDC评分平均为(59.87±8.77)分,分别较术前平均(51.33±14.99)分、(48.95±13.68)分明显提高(P<0.05)。结论 早中期的临床数据显示,同时进行ACLR联合UKA对UKOA合并ACLD手术治疗的临床疗效显著,可有效改善患者的膝关节不稳定和内侧间室疼痛,提高患者本体感觉,患者并发症发生率较低,值得临床推广应用,但应严格把握手术的适应证。

运动疗法对前交叉韧带重建后康复疗效影响的网状Meta分析

目的:运动干预被认为是前交叉韧带重建后康复的基础。然而,关于何种运动疗法在改善前交叉韧带重建后患者膝关节肌肉力量和功能方面更有效,目前仍未得出明确结论。为此,文章采用网状Meta分析方法,比较运动疗法治疗前交叉韧带重建后的疗效,为选择最佳运动疗法提供循证医学依据。方法:计算机检索PubMed,Web of Science,Embase,The Cochrane Library及EBSCO数据库运动疗法治疗前交叉韧带重建后的随机对照试验,检索时限均从建库至2023-11-20。结局指标包括股四头肌肌力、腘绳肌肌力、膝关节功能评分3个连续性变量。运用EndNote X9.1软件筛选文献。采用Cochrane风险偏倚评估工具对纳入的文献进行质量评价,根据GRADE评分对文章结果的证据强度进行评级,采用Stata 16.0进行网状Meta分析。结果:①共纳入36项随机对照试验,包括1179例前交叉韧带重建后患者,纳入文献整体质量中等;涉及9种运动疗法:等速训练、交叉训练、离心训练、水中康复、血流限制训练、运动控制训练、增强式训练、全身振动训练和综合训练;对照措施为常规康复训练。②网状Meta分析结果显示:与常规康复训练相比,离心训练(SMD=2.08,95%CI:0.56-3.60,P=0.007)对前交叉韧带重建后患者股四头肌肌力的改善效果最佳,其次是综合训练(SMD=1.69,95%CI:0.11-3.27,P=0.249)和全身振动训练(SMD=0.81,95%CI:0.11-1.51,P=0.042);在提升患者腘绳肌肌力方面,综合训练(SMD=2.08,95%CI:0.30-3.86,P=0.022)效果最佳,其次是增强式训练(SMD=1.51,95%CI:0.18-2.84,P=0.026)和等速训练(SMD=1.37,95%CI:0.06-2.67,P=0.039);综合训练(SMD=4.60,95%CI:2.40-6.80,P<0.001)改善膝关节功能评分最有效,其次是离心训练(SMD=1.75,95%CI:0.24-3.25,P=0.023)和水中康复(SMD=1.65,95%CI:0.07-3.24,P=0.041)。结论:低到中等强度的临床证据证实,在改善前交叉韧带重建后患者膝关节肌肉力量和功能方面,综合训练可能是最有效的运动疗法,其次是离心训练、增强式训练、等速训练、全身振动训练、水中康复。未来仍需更多高质量的临床随机对照试验来验证结论的可靠性。
