Dislocation in total knee arthroplasty

Student Projects

Abstract

Mobile-bearing total knee arthroplasty has potential advantages over fixed- bearing prostheses that may lead to an improvement of the range of motion and inferior long-term polyethylene wear. However, the potential disadvantages include the dislocation of the PE tibial insert that is usually the result of quadriceps deficiency, ligament laxity and traumatic events. Therefore, 2 goals are pursued in this project. In a first step, an analysis of the existing literature will let to find out the causes of bearing dislocation. In a second step, some of these causes will be reproduced in a 3D musculoskeletal model of the lower limb to investigate the effect on the tibial insert of the knee prosthesis FIRST (Symbios, Switzerland).

Knee replacement

Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources. It may also be performed for other knee diseases, such as rheumatoid arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk.

Hip replacement

Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.

Joint replacement

Replacement arthroplasty (from Greek arthron, joint, limb, articulate, + plassein, to form, mould, forge, feign, make an image of), or joint replacement surgery, is a procedure of orthopedic surgery in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. It is a form of arthroplasty, and is often indicated from various joint diseases, including osteoarthritis and rheumatoid arthritis.
