Abstract

Background:

Over the years, proponents of total knee designs (cruciate retaining and posterior stabilised) have conducted several long-term studies to claim the potential of these designs in several subsets of patients. Total knee arthroplasty (TKA) in patients with rheumatoid arthritis has also been one such domain where numerous studies were conducted in the past. A general perception among majority of arthroplasty surgeons is that, posterior stabilised (PS) is the implanted design of choice among patients with Rheumatoid arthritis (RA). However, with the available literature there is a significant disparity related to the selection of implants in patients with rheumatoid RA. In this review of literature, an attempt is made to identify the clinical performance and role of one such implant design, the cruciate retaining (CR) prosthesis in rheumatoid arthritis.

Method:

The review was conducted after a series of advanced search in the following medical databases; Pub med, Biomed central, Cochrane and Google scholar for articles related to long term follow up studies of cruciate retaining total knee arthroplasty in rheumatoid arthritis using the keywords cruciate retaining prosthesis, total knee arthroplasty, rheumatoid arthritis.

Results:

The available data demonstrate that the CR design is attributed with an excellent long term survivorship and functional outcome even in follow up studies up to twenty-five years.

Conclusion:

The advantages of using a CR design are long term survivorship, controlled femoral roll back and preservation of bone stock. Thus, the data gathered in this review lead to a consideration that the CR design is an implant design on par with PS design in patients with RA.
