The purpose this study was investigate influence preoperative level sports knee function with PFI were treated distal femoral osteotomy (DFO). Methods Patients underwent DFO recurrent associated increased antetorsion and/or valgus malalignment included. Psychological readiness resume sporting...

Abstract Purpose The purpose of the study was to report clinical, functional and radiological outcome following varus osteotomy as a salvage procedure in young middle-aged patients with patellofemoral arthritis (PFA) associated valgus malalignment. It hypothesized that significant improvement knee function reduction pain would be achieved. Moreover, no conversion joint arthroplasty could observed. Material methods Patients (< 50 years age) underwent between 08/2012 01/2020 for treatment...

Background: Biomechanical studies have shown that an increased medial posterior tibial slope (MPTS) may affect anteroposterior knee laxity and shear forces, ultimately increasing the risk for graft failure after anterior cruciate ligament (ACL) reconstruction. Previous clinical have, however, reported inconclusive results. Purpose: The purpose of this study was to evaluate relationship between MPTS as well functional outcomes anatomic primary isolated ACL reconstruction using a hamstring...

To evaluate clinical outcomes as well return to sports (RTS) and work (RTW) rates following anatomic lateral ankle ligament reconstruction with a tendon autograft for chronic instability (CLAI) in high-risk population, compare these outcome parameters between patients having received gracilis (GT) free split peroneus brevis (PBT) autograft.Twenty-eight consecutive patients, who were diagnosed CLAI, presenting ≥ 1 risk factor (ligamentous hyperlaxity, insufficient substance of native and/or...

The aim of this study was to investigate whether malrotation lateral knee radiographs influences posterior tibial slope (PTS) measurements.

Abstract Background Distal biceps tendon ruptures can lead to significant restrictions in affected patients. The mechanisms of injury described scientific literature are based exclusively on case reports and theoretical models. This study aimed determine the position upper extremities forces involved rupture through analyzing video recordings. Methods public YouTube.com database was queried for videos capturing a clear view distal rupture. Two orthopedic surgeons independently assessed...

Abstract Purpose Posterior lateral meniscus root (PLMR) tears are injuries that commonly occur together with anterior cruciate ligament (ACL) tears. The aim of this study was to evaluate the clinical and radiological outcome PLMR repair accompanying ACL reconstruction. Specifically, healing rates, meniscal extrusion behavior their influence on patient-reported measures (PROMs) were analyzed. It hypothesized shows satisfactory rates coronal does not increase significantly following repair....
