Reoperation rate, mortality and ambulatory ability after internal fixation versus hemiarthroplasty for unstable intertrochanteric fractures in elderly patients: a study on Korean Hip Fracture Registry.
The treatment of unstable intertrochanteric fracture in elderly patients is challenging and how to treat these patients remains controversial. The purposes of this study were to compare (1) reoperation rate, (2) mortality and (3) the postoperative change of walking ability between patients undergoing internal fixation (IF) and those undergoing bipolar hemiarthroplasty (HA) due to this type of fracture based on the data from the Korean Hip Fracture Registry. ⋯ This study showed HA was associated with lower rate of reoperation and lower decrement rate of walking ability compared to IF in elderly patients with unstable intertrochanteric fractures.

Preoperative psychological distress no reason to delay total knee arthroplasty: a register-based prospective cohort study of 458 patients.
Total knee arthroplasty (TKA) is effective in alleviating pain and improving function in patients with knee arthritis. Psychological factors are known to affect patient satisfaction after TKA. It is important to determine the effectiveness of TKA in patients with presurgical anxiety and/or depression to avoid excluding them from surgery. ⋯ II.

Arthroscopic transosseous rotator cuff repair: how to avoid damaging the axillary nerve-a cadaveric study.
Arthroscopic transosseous rotator cuff repair can be performed with an external guide, although the proximity to the axillary nerve raises safety concerns. The aim of this study is to determine the safety of different drilling angles regarding the axillary nerve. ⋯ Arthroscopic transosseous rotator cuff repair with an external guide does not pose a risk for the axillary nerve using angles of 60° or less.

Concomitant periarticular fractures predict worse patient-reported outcomes in multiligament knee injuries: a matched cohort study.
There is a shortage of high-level evidence regarding periarticular fractures affect outcomes after MLKIs. The purpose of this study was to determine whether concomitant periarticular fractures with mutliligament knee injuries (MLKIs) predict worse patient-reported outcomes (PROMs) when compared to MLKIs without concomitant periarticular fractures after surgical repair and/or reconstruction. ⋯ The presence of a periarticular fracture predicted significantly worse clinical outcomes in the setting of MLKI. These findings may be useful in determining the prognosis of MLKI with concomitant periarticular fractures treated with surgical repair and/or reconstruction.

A biomechanical comparison of Achilles tendon suture repair techniques: Locking Block Modified Krackow, Kessler, and Percutaneous Achilles Repair System with the early rehabilitation program in vitro bovine model.
The Krackow technique has the advantage of high strength, though it is not minimally invasive. The "Locking Block Modified Krackow" (LBMK) peri-tendon fixation technique was designed for minimally invasive surgery. This study aimed to compare the biomechanics of LBMK with Kessler and Percutaneous Achilles Repair System (PARS) techniques using a simulated early rehabilitation program. ⋯ The biomechanical strength of the LBMK suture was significantly greater than Kessler and PARS. The reduced gap in the LBMK group suggests superior resistance to gap formation, which may occur during early postoperative rehabilitation.
