Randomized Controlled TrialTranexamic acid is beneficial for blood management of high tibial osteotomy: a randomized controlled study.
The purpose of this study was to investigate whether TXA can effectively reduce blood loss after HTO and related complications and to evaluate its safety. ⋯ Intravenous TXA can effectively and safely reduce blood loss and bleeding-related complications after HTO and was beneficial for the blood management of HTO.

Multicenter StudyPatellar fractures in elderly patients: a multicenter computed tomography-based analysis.
This study aimed to demonstrate the characteristics of patellar fractures and evaluate clinical outcomes in elderly patients. ⋯ Patellar fractures in the elderly were mostly from low-energy injuries, and types C3 and A1 were the most common. CT images demonstrated high rates of an inferior pole involvement and comminution. The complication and reoperation rates were relatively high.

Randomized Controlled TrialApp-based rehabilitation program after total knee arthroplasty: a randomized controlled trial.
New app-based programs for postoperative rehabilitation have been developed, but no long-term study has been published to date. Thus, a prospective randomized control trial with 2-year follow-up was performed to evaluate the effectiveness of app-based rehabilitation (GenuSport) compared to a control group after total knee arthroplasty (TKA). ⋯ Level II, prospective randomized control trial.

Arthroscopic and open partial arthroplasty for the treatment of focal grade IV cartilage defects of the humeral head.
Focal Outerbridge grade IV cartilage defects of the proximal humerus may lead to pain and an impaired shoulder function. In cases of failed operative or conservative treatment options such as intraarticular injections or arthroscopic microfracturing of the subchondral bone, partial arthroplasty of the humeral may restore the articular surface of the humeral head without altering the anatomy. This study evaluates mid-term results of open and arthroscopic partial resurfacing of the humeral head in the context of focal grade IV cartilage defects. ⋯ Level IV (retrospective study).

Quantitative and individualized assessment of the learning curve in preoperative planning of the acetabular cup size in primary total hip arthroplasty.
The aim of the present study was to investigate the learning curves of 2 trainees with different experience levels to reach proficiency in preoperative planning of the cup size based on learning curve cumulative summation (LC-CUSUM) statistics and a cumulative summation (CUSUM) test. ⋯ LC-CUSUM/CUSUM allow for an individualized, quantitative and continuous assessment of planning quality. Based on LC-CUSUM statistics, the two trainees of this study gain proficiency in planning of the acetabular cup size after 50-100 attempts when an immediate feedback is provided. Previous experience positively influences the performance. The study serves as basis for the medical education of students and residents in joint replacement procedures.
