Patellar resurfacing in total knee arthroplasty (TKA) remains controversial. This study evaluates the results of resurfacing and non-resurfacing of the patella. Fifty-six patients with osteoarthritis (OA) of the knee were enrolled in a prospective randomised clinical trial using a posterior-stabilised TKA. Evaluations were done preoperatively and after 1, 3, 6, 12 and 24 months. Disease specifi...

Introduction: Distal Femoral fracture may lead to the development of post-traumatic arthrosis knee joint because direct intraarticular injury. Malunion distal femur fracture, intra-articular osseous defects, limb malalignment and compromised surrounding soft tissues in turn affect outcome total arthroplasty (TKA) makes it a technically demanding surgery. Here we report our experience regarding ...

BACKGROUND We were not aware of a well-validated patellofemoral joint-specific scoring system. We performed this study to develop and validate a scoring system (Samsung Medical Center [SMC] patellofemoral scoring system) suitable for the evaluation of patellofemoral joint status. METHODS We recruited 179 individuals consisting of a study group of 123 patients with anterior knee pain but witho...

There has been a recent increase in interest for non-cemented fixation in total knee arthroplasty (TKA), however the superiority of cement fixation is an ongoing debate. Whereas the results based on Level III and IV evidence show similar survivorship rates between the two types of fixation, Level I and II evidence strongly support cemented fixation. United Kingdom, Australia, Sweden,...

The thickness of the tibial polyethylene (PE) insert is a critical parameter to ensure optimal soft-tissue balancing in intraoperative decision-making procedure total knee arthroplasty (TKA). However, there paucity information about kinetic response PE variations tibiofemoral (TF) joint, and subsequently, secondary effects on patellofemoral (PF) biomechanics. Therefore, purpose this study was i...

Optimal patellar tracking and component alignment are important in achieving a well-functioning total knee arthroplasty (TKA). The patella is constrained partly by design of the prosthetic trochlear groove, and patellar tracking is governed by a combination of static and dynamic factors. Maltracking may result from excessive or unbalanced tension in the surrounding soft tissues. This article de...

STUDY DESIGN Single-group repeated measures design. OBJECTIVE To quantify patellofemoral joint reaction forces and stress while squatting with and without an external load. BACKGROUND Although squatting exercises in the rehabilitation setting are often executed to a relatively shallow depth in order to avoid the higher joint forces associated with increased knee flexion, objective criteria ...
