The history of mobile-bearing total knee replacement systems.

The use of a mobile-bearing knee system is routine in modern total knee arthroplasty (TKA). There are indications for use of a mobile-bearing TKA for a growing number of patients. The design, however, was not always well appreciated.

International multi-centre survivorship analysis of mobile bearing total knee arthroplasty.

We retrospectively reviewed the experience of a large international multi-centre study of primary total knee arthroplasty with mobile bearing design and modifications of the tibial component to allow for bicruciate preservation, posterior cruciate retention, or sacrifice. Twenty-seven surgeons performed 4,743 total knee replacements between 1981 and 1997. Implants inserted were 324 that retained both cruciate ligaments, 2,165 that retained the posterior cruciate, and 2,254 that sacrificed both cruciates.

[The total knee prosthesis: indications and complications].

Severe pain, impaired movement, serious deformity and (or) instability of the knee due to osteoarthritis or another joint disease are indications for total knee replacement. Contraindications are a high surgical risk and poor function of the M. quadriceps femoris.

Prevention of deep vein thrombosis following total hip replacement by low molecular weight heparinoid.

We assessed the safety and efficacy of the novel low molecular weight heparinoid Lomoparan (Org 10172) for the prevention of deep-vein thrombosis in patients undergoing elective total hip replacement in a randomized, placebo-controlled, double-blind trial in 197 consecutive patients. The heparinoid (750 anti-factor Xa-units, s.c.
