Fixed or mobile-bearing total knee arthroplasty
Fixed and mobile-bearing in total knee arthroplasty are still discussed controversially. In this article, biomechanical and clinical aspects in both fixed and mobile-bearing designs were reviewed. In biomechanical aspect, the mobile-bearing design has proved to provide less tibiofemoral contact stresses under tibiofemoral malalignment conditions. It also provides less wear rate in in-vitro simu...
متن کاملNontraumatic tibial polyethylene insert cone fracture in mobile-bearing posterior-stabilized total knee arthroplasty
A 72-year-old male patient underwent mobile-bearing posterior-stabilized total knee arthroplasty for osteoarthritis. He experienced a nontraumatic polyethylene tibial insert cone fracture 27 months after surgery. Scanning electron microscopy of the fracture surface of the tibial insert cone suggested progress of ductile breaking from the posterior toward the anterior of the cone due to repeated...
متن کاملWear-pattern analysis in retrieved tibial inserts of mobile-bearing and fixed-bearing total knee prostheses.
Components from 73 failed knee replacements (TKRs) consisting of rotating-platform, mobile-bearing and fixed-bearing implants were examined to assess the patterns of wear. The patterns were divided into low-grade (burnishing, abrasion and cold flow) and high-grade (scratching, pitting/metal embedding and delamination) to assess the severity of the wear of polyethylene. The rotating-platform gro...
متن کاملFixed- versus mobile-bearing total knee arthroplasty in Indian patients.
PURPOSE To compare the mid-term clinical outcomes in Indian patients after total knee arthroplasty (TKA) using a fixed- or mobile-bearing prosthesis. METHODS 120 consecutive patients (50 men and 70 women) aged 55 to 76 (mean, 63) years who had arthritis of the knee with similar deformity and range of motion were randomised to undergo TKA using a fixed- or mobile-bearing prosthesis. Patients w...
متن کاملRe: Comparison of mobile-bearing and fixed-bearing total knee arthroplasty: a prospective randomized study.
The purpose of this prospective randomized study was to compare the postoperative recovery and early results of 2 groups of patients undergoing total knee arthroplasty: 107 patients received an established fixed-bearing posterior-stabilized prosthesis (Legacy Posterior Stabilized [LPS]), and 103 patients the meniscal-bearing prosthesis (Meniscal Bearing Knee [MBK]). Surgical procedures were the...
