Randomised controlled trial of triclosan coated vs uncoated sutures in primary hip and knee arthroplasty

BACKGROUND Triclosan-coated vicryl plus suture(Ethicon, Inc.) was developed to reduce microbial colonisation during surgical procedures. However, its effect on wound healing and surgical site infections remain unclear after hip and knee arthroplasty surgery.AIM To determine the effect of triclosan-coated sutures(TCS) vs non-coated sutures on wound healing, following primary hip and knee arthroplasties.METHODS A single-centred, double-blind randomised controlled trial(RCT) was undertaken. We randomly allocated patients to receive either the triclosan-coated sutures(TCS vicryl plus) or non-coated sutures(NCS vicryl) during the closure of unilateral primary hip and knee arthroplasties. We utilised the ASEPSIS wound scoring system to evaluate wound healing for the first 6 weeks post-operatively.RESULTS One hundred and fifty patients undergoing primary total hip or knee arthroplasty over a one-year period were included. Eighty-one were randomised to the TCS group and 69 to the NCS group. Despite no statistically significant difference in the ASEPSIS scores among the study groups(P = 0.75), sensitivity analysis using the Mann Whitney test(P = 0.036) as well as assessment of the wound complications at 6 weeks follow up, demonstrated significantly higher wound complication rates in the TCS group(8 vs 1, P = 0.03).CONCLUSION No clear advantage was demonstrated for using the TCS. However, larger multicentred RCTs are required to validate their use in hip and knee arthroplasty surgery.

Associations among pain catastrophizing, muscle strength, and physical performance after total knee and hip arthroplasty

AIM To investigate whether reductions in pain catastrophizing associated with physical performance in the early period after total knee arthroplasty(TKA) or total hip arthroplasty(THA).METHODS The study group of 46 participants underwent TKA or THA. The participants were evaluated within 7d before the operation and at 14d afterwards. Physical performance was measured by the Timed Up and Go(TUG) test, and 10-m gait time was measured at comfortable and maximum speeds. They rated their knee or hip pain using a visual analog scale(VAS) for daily life activities. Psychological characteristics were measured by the Pain Catastrophizing Scale(PCS). Physical characteristics were measured by isometric muscle strength of knee extensors and hip abductors on the operated side. The variables of percent changes between pre-and postoperation were calculated by dividing post-operation score by pre-operation score.RESULTS Postoperative VAS and PCS were better than preoperative for both TKA and THA. Postoperative physical performance and muscle strength were poorer than preoperative for both TKA and THA. The percent change in physical performance showed no correlation with preoperative variables. In TKA patients, the percent change of PCS showed correlation with percent change of TUG(P = 0.016), 10-m gait time at comfortable speeds(P = 0.003), and 10-m gait time at maximum speeds(P = 0.042). The percent change of muscle strength showed partial correlation with physical performances.The percent change of VAS showed no correlation with physical performances. On the other hand, in THA patients, the percent change of hip abductor strength showed correlation with percent change of TUG(P =0.047), 10-m gait time at comfortable speeds(P = 0.001),and 10-m gait time at maximum speeds(P = 0.021). The percent change of knee extensor strength showed partial correlation with physical performances. The percent change of VAS and PCS showed no correlation with physical performances.CONCLUSION Changes in pain catastrophizing significantly associated with changes in physical performance in the early period after TKA. It contributes to future postoperative rehabilitation of arthroplasty.

Dynamic knee valgus kinematics and their relationship to pain in women with patellofemoral pain compared to women with chronic hip joint pain

Background:Dynamic knee valgus(DKV)is an abnormal movement pattern visually characterized by excessive medial movement of the lower extremity during weight bearing.Differences in hip and knee kinematic components of DKV may explain the emergence of different pain problems in people who exhibit the same observed movement impairment.Using a secondary analysis of exiting data sets,we sought to determine whether hip and knee frontal and transverse plane angles during a functional task differed between women with patellofemoral pain and women with chronic hip joint pain and the relationship between joint-specific kinematics and pain in these 2 pain populations.Methods:In the original studies,3-dimensional hip and knee kinematics during a single-limb squat were obtained in 20 women with patellofemoral pain and 14 women with chronic hip joint pain who demonstrated visually classified DKV.Pain intensity during the squat was assessed in both groups.For the secondary analysis,kinematic data were compared between pain groups using their respective control groups as a reference.Within each pain group,correlation coefficients were used to determine the relationship between kinematics and pain during the squat.Results:Hip adduction and contralateral pelvic drop were greater in those with chronic hip joint pain compared to those with patellofemoral pain(effect sizes ≥0.40).Greater knee external rotation(r= 0.47,p= 0.04)was correlated with greater knee pain in those with patellofemoral pain,while greater hip adduction(r = 0.53,p = 0.05)and greater hip internal rotation(r = 0.55,p = 0.04)were correlated with greater hip pain in those with chronic hip joint pain.Conclusion:Hip frontal plane motion was greater in those with chronic hip joint pain compared to those with patellofemoral pain.In both groups,greater abnormal movement at the respective joint(e.g.,knee external rotation in the patellofemoral pain group and hip adduction and internal rotation in the chronic hip joint pain group)was associated with greater pain at that joint during a single-limb squat.

The Association between Surgery Laterality in Orthopedists and the Choices of Prostheses in Total Knee and Hip Replacement

Background: Most orthopedists are right-handed. However, osteoarthritis occurs with equal frequency over both sides. Does perfect and effective arthroplasty surgery require ambidextrous motor skills? Objectives: In this study, we aimed to investigate the clinical features of arthroplasty for hip and knee joints (THR and TKR) on different sides affected by orthopedist laterality. Patients and Methods: All right-handed orthopedists performed 64 right and 52 left primary THR among 100 patients, and 115 right and 118 left primary TKR among 192 patients. Clinical and surgical features were retrospectively reviewed and analyzed. The body mass index (BMI), inner diameter of acetabular cup liners (ACD), diameter of the femoral head (FHD), diameter of the femoral stem (FSD), and the femoral neck length (FNL) were included in THR-receiving patients. The BMI, femoral component (FC) size, tibial plate (TP) size, and thickness of articular surface inserts (ASI) were included in TKR-receiving patients. Results: No significant differences were observed in ACD, FHD and FSD between patients receiving right and left THR groups (p = 0.16, 0.11, and 0.05, respectively). Similarly, there were no significant differences in FC, TP, and ASI between patients receiving right and left TKR groups (p = 0.06, 0.80, and 0.46, respectively). However, FNL in left THR group was significantly longer than that in right THR group (p = 0.01). Conclusion: This study showed that dexterity or proprioception in handedness had no affect on bone resection and thicknesses of the polyethylene in TKR and acetabular reaming and femoral canal rasping in THR. However, it did lead to differences in femoral neck resection. Right-handed orthopedists significantly tend to perform excessive femoral neck cutting or prefer the larger size of FNL when performing left side THR, while no differences occur when performing TKR.

Overweight and obesity in hip and knee arthroplasty:Evaluation of 6078 cases

AIM: To evaluate a possible association between thevarious levels of obesity and peri-operative characteristics of the procedure in patients who underwent endoprosthetic joint replacement in hip and knee joints. METHODS: We hypothesized that obese patients were treated for later stage of osteoarthritis, that more conservative implants were used, and the intraand perioperative complications increased for such patients. We evaluated all patients with body mass index(BMI) ≥ 25 who were treated in our institution from January 2011 to September 2013 for a primary total hip arthroplasty(THA) or total knee arthroplasty(TKA). Patients were split up by the levels of obesity according to the classification of the World Health Organization. Average age at the time of primary arthroplasty, preoperative Harris Hip Score(HHS), Hospital for Special Surgery score(HSS), gender, type of implanted prosthesis, and intra-and postoperative complications were evaluated.RESULTS: Six thousand and seventy-eight patients with a BMI ≥ 25 were treated with a primary THA or TKA. Age decreased significantly(P < 0.001) by increasing obesity in both the THA and TKA. HHS and HSS were at significantly lower levels at the time of treatment in the super-obese population(P < 0.001). Distribution patterns of the type of endoprostheses used changed with an increasing BMI. Peri- and postoperative complications were similar in form and quantity to those of the normal population. CONCLUSION: Higher BMI leads to endoprosthetic treatment in younger age, which is carried out at significantly lower levels of preoperative joint function.

Oral Tranexamic Acid in Hip and Knee Arthroplasty: A Prospective Cohort Study

Intravenous Tranexamic acid has been shown to decrease blood transfusion requirements in sur- gery. Little evidence exists regarding the much cheaper oral form. The objective of this cohort study was to evaluate whether oral tranexamic acid administration in patients undergoing elec- tive hip and knee replacement surgery resulted in decreased transfusion requirements. Methods: We assessed the transfusion requirements of 332 patients following unilateral total hip or knee arthroplasty, with the first 140 receiving no tranexamic acid and the next 192 given 1 g oral tranexamic acid one hour prior to and a further 1 g 4 hours post joint arthroplasty. Haemoglobin before and after surgery, the number of units transfused post-operatively and the incidence of deep vein thrombosis or pulmonary embolism were recorded. Results: In the first group, there were 22 instances of transfusion (15.7%) and a mean haemoglobin drop of 32.2 g/L, while the second (tranexamic acid) group had just 12 patients transfused (6.3%) and a mean haemoglobin drop of 24.6 g/L (both significantly less, p < 0.01). There was no significant difference in deep vein thrombosis or pulmonary embolism rates between groups. Conclusions: This is the first prospective study to analyze the outcome of oral tranexamic acid administration in hip and knee replacement. We conclude that oral tranexamic acid administration is a safe and effective means to decrease transfusion requirements in joint arthroplasty and is a much cheaper alternative to intravenous preparations of tranexamic acid.

Role of negative pressure wound therapy in total hip and knee arthroplasty

Negative-pressure wound therapy(NPWT) has been a successful modality of wound management which is in widespread use in several surgical fields. The main mechanisms of action thought to play a role in enhancing wound healing and preventing surgical site infection are macrodeformation and microdeformation of the wound bed, fluid removal, and stabilization of the wound environment. Due to the devastating consequences of infection in the setting of joint arthroplasty, there has been some interest in the use of NPWT following total hip arthroplasty and total knee arthroplasty. However, there is still a scarcity of data reporting on the use of NPWT within this field and most studies are limited by small sample sizes, high variability of clinical settings and end-points. There is little evidence to support the use of NPWT as an adjunctive treatment for surgical wound drainage, and for this reason surgical intervention should not be delayed when indicated. The prophylactic use of NPWT after arthroplasty in patients that are at high risk for postoperative wound drainage appears to have the strongest clinical evidence. Several clinical trialsincluding single-use NPWT devices for this purpose are currently in progress and this may soon be incorporated in clinical guidelines as a mean to prevent periprosthetic joint infections.

Two-stage revision arthroplasty for coagulase-negative staphylococcal periprosthetic joint infection of the hip and knee

BACKGROUND Periprosthetic joint infections(PJIs)are frequently caused by coagulase-negative Staphylococci(CoNS),which is known to be a hard-to-treat microorganism.Antibiotic resistance among causative pathogens of PJI is increasing.Two-stage revision is the favoured treatment for chronic CoNS infection of a hip or knee prosthesis.We hypothesised that the infection eradication rate of our treatment protocol for two-stage revision surgery for CoNS PJI of the hip and knee would be comparable to eradication rates described in the literature.AIM To evaluate the infection eradication rate of two-stage revision arthroplasty for PJI caused by CoNS.METHODS All patients treated with two-stage revision of a hip or knee prosthesis were retrospectively included.Patients with CoNS infection were included in the study,including polymicrobial cases.Primary outcome was infection eradication at final follow-up.RESULTS Forty-four patients were included in the study.Twenty-nine patients were treated for PJI of the hip and fifteen for PJI of the knee.At final follow-up after a mean of 37 mo,recurrent or persistent infection was present in eleven patients.CONCLUSION PJI with CoNS can be a difficult to treat infection due to increasing antibiotic resistance.Infection eradication rate of 70%-80%may be achieved.

Implant retention after acute and hematogenous periprosthetic hip and knee infections: Whom, when and how?

Periprosthetic joint infections(PJI) of the hip and the knee are grossly classified as early post-operative, acute hematogenous and late chronic infections. Whereas two-stage exchange arthroplasty is the standard of care in North America for treating chronic infections, irrigation and debridement(I and D) with retention of implants has been used in an attempt to treat the other two types of PJIs. The rationale of this approach is that a PJI may be eradicated without the need of explanting the prostheses, as long as it has not transitioned into a chronic state. With the present paper, we review current evidence regarding the role of I and D with implant retention for treating PJIs of the hip and the knee. While a very wide range of success rates is reported in different studies, a short period of time between initiation of symptoms and intervention seems to play a prominent role with regards to a successful outcome. Moreover, pathogens of higher virulence and resistance to antibiotics are associated with a poorer result. Specific comorbidities have been also correlated with a less favorable outcome. Finally, one should proceed with serial I and Ds only under the condition that a predefined,aggressive protocol is applied. In conclusion,when treating a PJI of the hip or the knee, all the above factors should be considered in order to decide whether the patient is likely to benefit from this approach.

Patient Education Level and Utilization of Internet Resources by Patients in Orthopedic Hip and Knee Consultations

Introduction: Internet has become an increasingly popular source of reference for patients to learn about their medical problems. It is easily accessible, and a large number of uncensored information is available online written from various sources and perspectives. However, the role of internet and its impact on patient’s care and understanding of the disease remains unclear. The purpose of this study is to evaluate the role and effect of internet use for patients seeking consultation for hip and knee arthritis. More specifically, the relationship between patient’s education level, internet use, motives for doing background readings, perception of internet information, and reactions to the available information will be studied. Method: Patients seeking orthopaedic consultation for knee or hip arthritis at the Toronto Western Hospital were identified and invited to fill out a questionnaire on their first visit. The questionnaire was designed to assess the patients’ pre-consultation reading habits, their use of internet, and their reaction to what they have read on the internet. The questionnaire also included questions about the respondent’s background.Results: In comparing patients holding college/university degree (CU) with patients having no college/university education (NoCU), the CU group were associated with increased internet use (CU vs. NoCU: 71.0% vs. 48.3%;p 0.01) and background reading (CU vs. NoCU: 82.2% vs. 17.8%;p 0.001) prior to consultation;fewer incidence of anxiety following internet use (CU vs. NoCU: 29.9% vs. 53.6%;p 0.05);and higher rates of decisions influenced by internet use (CU vs. NoCU: 20.8% vs. 3.6%, p 0.05). Internet users demonstrated a higher confidence in gathering and understanding medical information (Internet users vs. non-internet users: 6.59 ± 2.05 vs. 5.03 ± 2.78;p 0.001) and rated the accuracy of information on internet at 7.18 ± 2.01 (max = 10). Conclusion: Internet use can influence patient’s treatment decision, anxiety level, and understanding of their disease. Caregivers must recognize the growing trend of internet use and should counsel and educate their patients appropriately based on what they have read to help them accurately appreciate the nature of their disease.

Thromboprophylaxis for Hip and Knee Arthroplasty: Current Managements and Review of the Literature

Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA) are major surgical procedures which can cause high morbidity and even mortality. Among these complications is venous thrombo embolism (VTE) comprising deep vien thrombosis (DVT) and pulmonary embolism (PE). Therefore, after these operations, thromboprophylaxis is routinely used. However, it has some complications such as bleeding, adverse effect of chemical agents for using prevention of DVT. Anti-thrombotic prophylaxis includes: low molecular weight heparin (LMWH), fondaparinux, apixaban, dabigatran, rivaroxaban, low dose unfractionated heparin (LDUH), adjusted dose vitamin K antagonist (VKA), aspirin, or mechanical thromboprophylaxis devices. All over the World, orthopaedic surgeons consider a balance between thromboprophylaxis and bleeding. However, it has been still controversy about optimum prophylaxis for DVT. In this current paper, we aimed to review the literature under light of the current studies.

Metastatic Rectal Adenocarcinoma of the Hip and Knee Joints: A Case Series

Two cases are presented of patients with a history of metastatic rectal adenocarcinoma presenting with a painful joint effusion. Both cases are potential examples of metastasis to periarticular bone with local infiltration to the synovium, which is one proposed mechanism of intrasynovial metastasis. While skeletal metastases are a relatively common occurrence in metastatic adenocarcinoma, intraarticular metastasis is extremely rare. These cases highlight the need to consider metastasis in the differential of joint swelling in the setting of a history of adenocarcinoma.

Radiographic assessment of leg alignment and grading of knee osteoarthritis:A critical review

Knee osteoarthritis(OA) is a progressive joint disease hallmarked by cartilage and bone breakdown and associated with changes to all of the tissues in the joint,ultimately causing pain,stiffness,deformity and disability in many people.Radiographs are commonly used for the clinical assessment of knee OA incidence and progression,and to assess for risk factors.One risk factor for the incidence and progression of knee OA is malalignment of the lower extremities(LE).The hipknee-ankle(HKA) angle,assessed from a full-length LE radiograph,is ideally used to assess LE alignment.Careful attention to LE positioning is necessary to obtain the most accurate measurement of the HKA angle.Since full-length LE radiographs are not always available,the femoral shaft-tibial shaft(FS-TS) angle may be calculated from a knee radiograph instead.However,the FS-TS angle is more variable than the HKA angle and it should be used with caution.Knee radiographs are used to assess the severity of knee OA and its progression.There are three types of ordinal grading scales for knee OA:global,composite and individual feature scales.Each grade on a global scale describes one or more features of knee OA.The entire description must be met for a specific grade to be assigned.The KellgrenLawrence scale is the most commonly-used global scale.Composite scales grade several features of knee OA individually and sum the grades to create a total score.One example is the compartmental grading scale for knee OA.Composite scales can respond to change in a variety of presentations of knee OA.Individual feature scales assess one or more OA features individually and do not calculate a total score.They are most often used to monitor change in one OA feature,commonly joint space narrowing.The most commonly-used individual feature scale is the OA Research Society International atlas.Each type of scale has its advantages;however,composite scales may offer greater content validity.Responsiveness to change is unknown for most scales and deserves further evaluation.
