Comparative StudyComparison of two-stage revision arthroplasty and intramedullary arthrodesis in patients with failed infected knee arthroplasty.
Failed total knee arthroplasty (TKA) with significant bone loss and compromised soft-tissues is challenging and the final results are often inferior to patient's expectation. The objective of this study was to present a comparison of outcomes in patients with failed infected TKA treated with two-stage revision TKA or knee arthrodesis and to assess clinical and functional results, implant survival and infection recurrence. The hypothesis was that an arthrodesis may result in beneficial effects on patients' outcome. ⋯ Level III, retrospective cohort study.

Review Meta AnalysisThe efficacy and safety of knotless barbed sutures in total joint arthroplasty: a meta-analysis of randomized-controlled trials.
The knotless barbed sutures (KBS) are an innovative type of suture that can accelerate the placement of sutures and eliminate knot tying. Whether the KBS are safe and efficient in total joint arthroplasty (TJA) remains controversial. Therefore, we conducted a meta-analysis to evaluate its efficacy and safety. ⋯ Our findings suggest that KBS are a safe and effective method for TJA. Given the possible biases, adequately powered and better designed studies with longer follow-up are required to reach a firmer conclusion.

Meta AnalysisIneffectiveness of lateral-wedge insoles on the improvement of pain and function for medial knee osteoarthritis: a meta-analysis of controlled randomized trials.
The study aimed to evaluate the role of lateral-wedge insoles in pain reduction and functional improvement among patients with medial knee osteoarthritis. ⋯ Though for young Asian patients within normal BMI, to some extent, the lateral-wedge insoles seems to be helpful. However, there was no evidence to demonstrate the relationship between race and role of lateral-wedge insoles on pain reduction. All in all, based on current data, lateral-wedge insoles appear to be ineffective at attenuating knee pain and function improvement.

Randomized Controlled Trial Comparative StudyPronator quadratus repair with a part of the brachioradialis muscle insertion in volar plate fixation of distal radius fractures: a prospective randomised trial.
Stable pronator quadratus repair following volar plate fixation of distal radius fractures with complete plate coverage is difficult. ⋯ Pronator quadratus repair with a part of the brachioradialis muscle insertion is a reliable technique for coverage of a volar plate by slight distal transposition. In the repair of distal radius fractures, this may better protect the finger flexor tendons against irritation and/or rupture. That likelihood should now be studied.

Long-term survival of the cemented Müller CDH stem: a minimum follow-up of 10 years.
Total hip arthroplasty in patients with altered anatomy of the hip and femur, such as in congenital dysplasia of the hip, is challenging and often requires specially designed stems. Müller straight stems have shown excellent long-term results; however, long-term data on the analogous cemented Müller CDH stem are still missing. The aim of this study was to analyze long-term survival, identify potential risk factors for aseptic loosening, and analyze radiological outcome of the cemented Müller CDH stems. ⋯ Long-term survival of the cemented Müller CDH stem is comparable to other Müller-type straight stems and uncemented implants. Similar to the original Ti Müller straight stem, the Ti Müller CDH stem also showed an increased risk for aseptic loosening and should, therefore, no longer be used.
