Increased time from injury to surgical repair in patients with proximal hamstring ruptures is associated with worse clinical outcomes at mid-term follow-up.
Prior studies of hamstring tendon tears have reported varied findings on whether increased delay from injury to surgery is associated with worse outcomes. The purpose of this study was to determine whether increased time from injury to surgical repair is associated with worse clinical outcomes in patients with proximal hamstring ruptures. ⋯ This study found that acute repair performed within 6 weeks of injury appears to yield improved PROs compared to chronic repair. These data highlight the importance of timely and accurate diagnosis of proximal hamstring ruptures and early operative intervention for surgical candidates.

Current practice of concomitant surgeries in cartilage repair of the femorotibial compartment of the knee: baseline data of 4968 consecutive patients from the German cartilage registry (KnorpelRegister DGOU).
The treatment of underlying comorbidities is a field of rising interest in cartilage repair surgery. The aim of this study was to analyze the current practice of concomitant surgeries in cartilage repair of the knee especially in the medial or lateral femorotibial compartment. Type, frequency and distribution of additional surgeries for correction of malalignment, knee instability and meniscus deficiency should be evaluated. ⋯ II.

Comparative StudyFixation stability and implant-associated complications in periacetabular osteotomy: a comparison of screw and K-wire fixation.
The aim of this study was to compare the fixation stability and complications in patients undergoing periacetabular osteotomy (PAO) with either K-wire or screw fixation. ⋯ III, retrospective trial.

Locking suture repair versus ligament augmentation-a biomechanical study regarding the treatment of acute lateral collateral ligament injuries of the elbow.
Lateral collateral ligament (LCL) tears are frequently observed in fractures and dislocations of the elbow. Recent biomechanical evidence suggests that additional ligament augmentation may improve repair stability. The aim of this biomechanical in-vitro study was to compare the resistance of a locking suture repair of the LCL with a ligament augmentation technique. ⋯ Basic science study, biomechanics.

Randomized Controlled TrialClinical results after arthroscopic reconstruction of the posterolateral corner of the knee: A prospective randomized trial comparing two different surgical techniques.
Arthroscopic reconstruction techniques of the posterolateral corner (PLC) of the knee have been developed in recent years. Reconstruction techniques for higher-grade PLC injuries have not yet been validated in clinical studies. This study aimed to compare clinical outcomes of two different techniques and to present results of the first prospective randomized clinical trial of patients to undergo these novel procedures. ⋯ This study indicates sufficient restoration of posterolateral rotational instability, varus instability and posterior drawer after arthroscopic posterolateral corner reconstruction without neurovascular complications. Increased postoperative range of motion and a shorter and less invasive surgical procedure could favor the arthroscopic reconstruction technique according to Arciero over LaPrade's technique in future treatment considerations.
