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.

Treatment of advanced stage osteochondrosis dissecans in the adolescent elbow using a hyaloronic acid-based scaffold: a case series of 5 patients.
Osteochondrosis dissecans (OCD) is considered to be one of the main causes for pain, discomfort and morbidity in the pediatric elbow joint. Few treatment options, such as microfracture or autologous transplantation, of osteochondral bone grafts have been described to address advanced OCD. The aim of this retrospective case series is to present preliminary clinical and radiologic findings following advanced stage OCD repair using a novel combination of a hyaluronic acid-based scaffold with autologous iliac crest bone grafting. ⋯ This study showed promising clinical short- to mid-term results in adolescent patients with advanced OCD using a novel surgical treatment combination. Radiographic results showed partial healing; hence, residual changes should be monitored over a longer period.

Evaluation of the accuracy of resected bone thickness based on patient-specific instrumentation during total knee arthroplasty.
In total knee arthroplasty (TKA) using patient-specific instrumentation (PSI), the correlation between the preoperative surgical plan and intraoperative resection size is unclear. The aims of this study were to evaluate whether the computed tomography (CT)-based PSI surgical plan can be executed accurately and to determine the accuracy of bone resection in TKA using PSI. ⋯ PSI showed only fair-to-moderate accuracy. The cutting guide for the posterior femur was less accurate than that for the tibia and distal femur. Specific attention is required when cutting the posterior femur. The PSI design needs to be improved to reduce errors.

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.
