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 ...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.展开更多

Aim: To investigate the prevalence of types of meniscus tears in patients with Anterior Cruciate Ligament (ACL) Injury. Methods: A retrospective study was conducted among inpatients. Clinical evaluation included side-to-side difference in anterior tibial translation (ATT) as measured by a KT-1000 arthrometer (MEDmetric Corp) and a grade of pivot-shift test at final follow-up in all patients. Subsequent meniscal tear was defined by symptoms of joint line pain and/or locking or joint effusion requiring surgical treatment. Results: Most of patients were males (92.6%). The patients were categorized into 5 groups according to age with a mean of age 32.8 ± 10.6. The most common causes of ACL injury were falling down (43.2%), trauma (38.1%) or knee torsion (18.8%). Medial meniscal tear was found in 92 knees (55.7%), while lateral meniscal tear was found in 19 knees (10.8%) and the most common type was the longitudinal tear that was found in 31 knees (17.6%). Similarly, 66.7% of the meniscal flap tears and half of the meniscal bucket-handle tears were significantly associated with loose body (P Conclusion: The present study demonstrated that meniscus tears are more common in individuals with chronic ACL rupture. The main factors contributing to ACL injury were classified as falls, trauma, and knee torsion. Gender was identified as a critical determinant in the etiology of ACL injury. The occurrence of a ramp lesion was associated longitudinal meniscal tears, whereas chodoral injury was associated with the majority of meniscal flap tears and meniscal bucket-handle tears.展开更多

Methods: 36 patients who visited our hospital from January 2020 to September 2023 were selected as research subjects and randomly divided into the study group (18 cases) and the control group (18 cases). The control group adopted routine examination and rehabilitation training, and the study group adopted sports medicine ultrasound and rehabilitation training. The ankle function scores and daily living ability of the two groups were compared before treatment and 9 weeks after treatment. Results: There was no statistically significant difference between the study group and the control group in terms of ankle function scores and ability to perform activities of daily living before treatment (P > 0.05), but the difference was statistically significant after treatment (P < 0.05). Conclusion: Ultrasound can be used as a supplement to magnetic resonance imaging (MRI) of the ankle joint for diagnosing anterior talofibular ligament injury;ultrasound can show the location, distance, and degree of tear of the anterior talofibular ligament rupture and accurately predict muscle atrophy around the ankle joint;ultrasound combined with computed tomography (CT) can better determine the type of intra-articular fracture of the talar subtalar joint, and guide the choice of surgical timing. In addition, ultrasound can be used to determine the severity of peroneal muscle atrophy, assess the progress of early postoperative functional exercise, and guide personalized rehabilitation programs.展开更多

Subjects: 13 patients, 10 with medial, and 3 with lateral ligament injury. Methods: non-operative management consisted of employing a brace to prevent sagittal translation of the tibia. Quadriceps muscle and early passive knee motion exercises in the brace was encouraged immediately after arthroscopy. Weight-bearing was forbidden for 3 weeks. The brace was not removed for 3 months. Follow-up periods ranged from 2 to 6 years (mean, 3 years 2 months). Results: none, but one patient had a slight restriction of knee flexion. Quadriceps muscle strength revealed an average of 89.0% of normal side. The knee score indicated 2 patients rated good, 3 rated fair, and 8 rated poor. The score correlated with measurements of anterior and posterior translation on the stress radiograph significantly. Stress radiography revealed that anterior laxity was reduced better than posterior laxity significantly. Conclusion: non-operative brace therapy can be considered for this combined injury as the initial treatment. A late reconstruction would be performed when the result was not satisfactory. Preserved range of motion and muscle strength after brace therapy had a great advantage to the late reconstructive surgery.展开更多

文摘目的比较关节镜下前交叉韧带(anterior cruciate ligament,ACL)全内重建中,由外向内技术和经前内侧入路技术制作股骨隧道对术后临床疗效的差异。方法收集2020年2月至2022年6月徐州市中心医院运动医学科收治的60例ACL断裂患者,根据手术技术的不同,分为观察组(由外向内技术)30例和对照组(经前内侧入路技术)30例。其中观察组男20例,女10例;年龄24~37岁,平均(29.30±4.00)岁;对照组男17例,女13例;年龄23~40岁,平均(29.70±4.21)岁;比较两组患者术前、术后6个月、12个月膝关节Lysholm评分和美国膝关节协会评分(knee society score,KSS);比较两组患者术前和末次随访膝关节松弛度;随访期间记录两组患者伤口感染、肌腱松动、术后再次翻修等情况。结果所有患者均获随访,随访时间12~18个月,观察组平均随访(15.37±1.61)个月,对照组平均随访(14.97±1.56)个月;术后12个月,观察组膝关节前抽屉试验、Lachman试验和轴移试验结果与对照组患者相似,差异无统计学意义(P>0.05);术后6个月和12个月两组患者膝关节Lysholm评分和KSS评分相似,差异无统计学意义(P>0.05);随访期间,两组患者均未发生伤口感染、肌腱松动、术后再次翻修等情况。结论ACL全内重建中,选择经前内侧入路技术或由外向内技术制作股骨隧道均能实现股骨隧道的解剖定位,术后两组患者膝关节功能恢复良好,短期疗效均可接受。
