The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics. ⋯ The identification of important papers will help current clinicians and scientists to get an overview on past and current trends in that special field of ACL injury and provides a basis for both further discussion as well as future research.

The aim of this study was to illustrate safety, feasibility and advantages of transfracture medial transposition of the radial nerve during the lateral approach and lateral plating of humeral fractures located in the mid and distal shaft. ⋯ Transfracture transposition of the radial nerve during open reduction and internal fixation of humeral shaft fractures is a safe, harmless and feasible procedure when applied for fractures of the middle and distal humeral shaft; it removes the nerve from the surgical field during fracture manipulation and fixation, with a gain in length of the nerve by transforming its course from spiral to straight. Following radial nerve transposition across the fracture, a repeat surgical approach to the humerus for hardware removal or treatment of nonunion transforms the procedure into a simple one; the skin incision is carried straight down to the bone without the need to identify or dissect the nerve that was previously transposed to the medial compartment of the arm.

The main goal of this study was to retrospectively evaluate the clinical, functional and radiographic outcomes of displaced medial epicondyle fractures with or without associated elbow dislocation in children undergoing surgical treatment and to evaluate upper-extremity function with the Quick Disbilities of the Arm, Shoulder and Hand (Quick DASH) questionnaire. The hypothesis was that patients with associated elbow dislocation would have similar functional outcome to patients with displaced fractures with or without intra-articular entrapment of the medial epicondyle. ⋯ Children with type II, III and IV medial epicondyle fractures undergoing surgical treatment have good radiological, clinical and functional outcome but warrant special attention to detect intra-articular entrapment of the broken epicondyle. In these cases, both patient and family should be warned of the potential risk of loss of elbow range of motion and possibly poor functional outcome, especially if treatment is delayed.

Randomized Controlled Trial
Does vitamin E-blended polyethylene reduce wear in primary total hip arthroplasty: a blinded randomised clinical trial.
Some data indicate that first-generation highly cross-linked polyethylene (HXLPE) can oxidise in vivo and is associated with reduced mechanical properties. To overcome these limitations, a natural anti-oxidant vitamin E has been added to HXLPE to preserve the mechanical properties and decrease oxidative degradation whilst conserving high wear resistance. We hypothesised that after a minimal three years of follow-up the use of vitamin E-blended HXLPE would result in lower radiographic wear when compared with ultra-high molecular weight polyethylene (UHMWPE). ⋯ This study demonstrated that femoral head penetration was lower when using vitamin E-blended HXLPE when compared with UHMWPE, with a steady-state penetration rate far below the osteolysis threshold. Longer-term follow-up is needed to warrant whether wear reduction will generate less occurrence of osteolysis and aseptic loosening.

Review Meta Analysis
A systematic review and meta-analysis of platelet-rich plasma versus corticosteroid injections for plantar fasciopathy.
To determine whether platelet-rich plasma (PRP) injections are associated with improved pain and function scores when compared with corticosteroid injections for plantar fasciopathy. ⋯ PRP injections are associated with improved pain and function scores at three month follow-up when compared with corticosteroid injections. Information regarding relative adverse event rates and cost implications is lacking. Further, large-scale, high-quality, randomised controlled trials with blinding of outcome assessment and longer follow-up are required.
