Distal femoral osteotomy for the treatment of chronic patellofemoral instability improves gait patterns Open
Purpose The purpose of this study was to evaluate pre- to postoperative changes in clinical and functional outcomes as well as gait patterns in patients who underwent surgery for chronic patellofemoral instability (PFI). Methods Patients w…

Derotational distal femoral osteotomy for patients with recurrent patellar instability and increased femoral antetorsion improves knee function and adequately treats both torsional and valgus malalignment Open
Purpose The aim of the study was to evaluate the functional and radiological outcome following derotational distal femoral osteotomy (D‐DFO) in patients with high‐grade patellofemoral instability (PFI) and an associated increased femoral a…

Movement Coordination during Functional Single-Leg Squat Tests in Healthy, Recreational Athletes Open
The single-leg squat (SLS) represents a functional movement task for determining leg function. Objective movement analysis is required to evaluate inter-limb symmetry and movement coordination. Therefore, this study aimed to investigate in…

The lack of retropatellar resurfacing at index surgery is significantly associated with failure in patients following patellofemoral inlay arthroplasty: a multi‐center study of more than 260 patients Open
Purpose To evaluate the clinical outcomes of patients with a minimum 2‐year follow‐up following contemporary patellofemoral inlay arthroplasty (PFIA) and to identify potential risk factors for failure in a multi‐center study. Methods All p…

Preoperative patellofemoral anatomy affects failure rate after isolated patellofemoral inlay arthroplasty Open
Purpose To analyze whether preoperative patellofemoral anatomy is associated with clinical improvement and failure rate after isolated patellofemoral arthroplasty (PFA) using a modern inlay-type trochlear implant. Methods Prospectively col…

Objective visualization of the effect of different knee flexion angles on medial-lateral displacement of the knee center in frontal plane during single-Leg Squat Open
Introduction: The subjective single-leg squat (SLS) test can be used as a functional diagnostic agent to prevent knee injuries. [1] However, there are missing objective data about its functional rating, performance, squat depth and medio-l…

Role of activation patterns of hip muscles in single-leg squats in healthy patients Open
Introduction: A risk factor for knee injuries is the medio-lateral displacement of the knee joint during a single-leg squat (SLS). It is to be supposed that different activation patterns of hip muscles are related to the medio-lateral disp…

Reliable improvements in participation in low‐impact sports following implantation of a patellofemoral inlay arthroplasty at mid‐term follow‐up Open
Purpose The aim of this study was, to investigate the rate of return to sports (RTS) and physical activity after implantation of PFIA and to identify factors predictive of improved postoperative sporting ability. Methods Sixty‐two patients…
