Knee Replacement Arthroplasty (Subscribe)  

Stickler syndrome is believed to be the most common connective tissue disorder in Europe and the USA. Severe osteoarthritis sets in at very early age in 3rd to 4th decade of life necessitating joint arthroplasty. This case report highlights the intraoperative surgical difficulties faced by the surgeon and the planning...

Mastocytosis is a rare, heterogeneous disorder, of normal, active mast cells. The increase in mast cells is usually localised to the skin, but occasionally occurs in other organs as a systemic disorder. We report a case where systemic mastocytosis was diagnosed following biopsy of the femur during total knee replacement.

Questions/purposes We describe special operative considerations that must be made when performing TKA on patients with skeletal dysplasia, including implant selection and ligamentous balancing.
Conclusions Special considerations must be made with regard to implant selection and ligamentous balancing as a result of the unusual anatomy and deformities that accompany...

The OrthoPilot TKA navigation system (B. Braun Aesculap, Tuttlingen, Germany) offers software to optimize soft tissue balance using gap balance techniques. However, there are no studies on the reliability of the navigation-guided gap technique. The goal of this study is to establish the reliability of the navigation-guided gap technique. The...

Introduction Patients' expectations are variably reported to influence self-rated outcome and satisfaction after medical treatment; this prospective study examined which of the following was the most important unique determinant of global outcome/satisfaction after total knee arthroplasty (TKA): baseline expectations; fulfilment of expectations; or current symptoms and function.
Conclusions In this group, preoperative expectations...

Abstract - Polyethylene wear, with resultant particle-induced osteolysis, is a cause of late failure of total knee arthroplasty. The causes of both wear and osteolysis are multifactorial; still, improvements in the polyethylene liner have been investigated. Available highly cross-linked polyethylene tibial liners and patellar prostheses differ greatly in the amount...

Ankylosis of the knee is a severe functional limitation that becomes worse when pain is present. Arthrodesis of the knee is a classical indication for such patients, since it resolves the pain; however, the severe functional limitation remains.
METHODS In the present study, we evaluated the clinical course of nine patients who...

Conclusions: Minimal invasion surgery in total knee arthroplasty showed no improvement over a standard approach.

Previous osteotomy may compromise subsequent knee replacement, but no guidelines considering knee arthroplasty after prior osteotomy have been developed. We describe a systematic review of non-randomized studies to analyze the effect of high tibial osteotomy on total knee arthroplasty.
Conclusion: Our analysis suggests that osteotomy does not compromise subsequent knee replacement....

Total knee replacement in some form has been practiced for over 50 years. The complexities of the knee joint only began to be understood 30 years ago. Because of this, total knee replacement initially was not as successful as Sir John Charnley's artificial hip. However, over the last 20 years,...

As a result of repeated episodes of articular bleeding from early childhood adult patients with haemophilia commonly have severe damage to the knee. They may present to the orthopaedic surgeon with pain and severe functional disability arising from advanced haemophilic arthropathy. There are many reports of successful operations on the...

Between July 1986 and August 1996, we performed 32 total knee arthroplasties (TKA) on 32 patients with partially or completely ankylosed knees secondary to infection. Their mean age at surgery was 40 years (20 to 63) and the mean follow-up was ten years (5 to 13). The mean post-operative range...

Unicompartmental knee arthroplasty has had varying degrees of acceptance since its introduction approximately 30 years ago. Frequent and early failures were cited in initial studies. By the late 1990s, however, unicompartmental knee arthroplasty for the treatment of localized knee arthritis was becoming more common, and early outcome reports were favorable....
