Effects of Preoperative Telerehabilitation on Muscle Strength, Range of Motion, and Functional Outcomes in Candidates for Total Knee Arthroplasty: A Single-Blind Randomized Controlled Trial.

This study aims to investigate the effect of a preoperative telerehabilitation (PT) program on muscle strength, knee range of motion (ROM), and functional outcomes in candidates for total knee arthroplasty (TKA). Sixty patients (all women, mean age 70.53 ± 2.

Arthroscopic removal of separated bipartite patella causing snapping knee syndrome.

The bipartite patella is a developmental osseous variant that is found in approximately 2% to 6% of the population, and is bilateral in 50%. The proposed etiologies include old nonunion, osteochondritis, and congenital growth defect. It is often found incidentally around the inferior pole, lateral margin, or superolateral border of the patella.

A case of fracture of posterior margin of lateral tibial plateau by pivot shift mechanism in chronic ACL insufficiency.

We present a case of the fracture of the posterior margin of the lateral tibial plateau, probably by pivot shift mechanism in a chronic anterior cruciate ligament (ACL) insufficient knee. Multitudes of direct and indirect signs of ACL injury were evident on MRI, including anterior translation of the lateral tibial plateau, buckling of the posterior cruciate ligament, deep sulcus sign, and the fracture of the posterior aspect of lateral tibial plateau. With careful interpretation of the history and arthroscopic findings, the main insult of the current case was identified as the fracture of the posterior margin of the lateral tibial plateau with antecedent chronic ACL insufficiency, rather than as the acute or subacute ACL rupture.

Lateral epicondylar femoral avulsion fracture combined with tibial fracture: a counterpart to the arcuate sign.

We present a case of femoral avulsion of the lateral collateral ligament (LCL) with complete tear of the posterior cruciate ligament (PCL) and popliteus tendon accompanied by demonstrable posterolateral rotary instability (PLRI) of the knee. A 55-year-old man was involved in a road traffic accident. Radiographs revealed an avulsion fracture of the lateral epicondyle of the femur and a fracture of the tibial shaft.
