Purpose The purpose of this study was to determine the results of mobile bearing unicompartmental knee arthroplasty (UKA) with an intentionally increased flexion angle of the femoral component in patients requiring high flexion. Materials and Methods We investigated 45 knees treated by UKA. Clinically, we measured the range of motion (ROM) and the American Knee Society (AKS) score preoperativ...

BACKGROUND AND PURPOSE The long-term outcome of patellofemoral arthroplasty is related to progression of femorotibial osteoarthritis with need for conversion to total knee arthroplasty. We investigated whether prior patellofemoral arthroplasty compromises the results of total knee arthroplasty. METHODS 13 patients who had had 14 Richards type II patellofemoral arthroplasties converted to tota...

We aimed to determine factors that affect the quality of life of patients undergoing a standardized surgical and postoperative management protocol for knee dislocations. A total of 31 patients (33 knees) were included in this study. We contacted patients at a minimum of 12 months postoperatively (mean: 38 months; range, 12-111 months) and administered the previously validated Multiligament Qual...

The aim of this biomechanical study was to investigate knee joint kinematics following total knee arthroplasty. We compared eight congruent posterior cruciate ligament retaining and four ultracongruent cruciate sacrificing Natural Knee prostheses to the untreated human cadaveric knee joint. A six-degree-of-freedom testing device was used to evaluate knee joint kinematics with a load of 300 Newt...

Larsens syndrome is a rare genetic disorder characterized by multiple joint dislocations, abnormal facial features, and ligamentous laxity.Dislocation can involve Hips, knees, elbows, other joints. it was first described Larsen et al in 1950 [1]. Pierre Robin sequence another congenital birth defect That microganthia, glossoptosis cleft palate which lead to variety of functional abnormalities i...
