Abstract
Aim
To assess the outcome and complication rate of rotating hinge knee prostheses in our unit.
Method
From our knee database we have identified 137 consecutive rotating hinged TKRs (implanted 2004–2010) for severe instability, arthrofibrosis and severe bone loss in either primary or revision arthroplasty. Prospective pre-operative scores and post-operative scores were obtained. 23 had died or were lost to follow-up. This left 114 cases with complete outcome and complication data.
Results
The mean preoperative American Knee Score of 30.4 improved to 85.5 at a mean follow up of 4.2 years. Complications included: re-revision (6), manipulation (3), infection (2 cases) and above knee amputation (1).
Conclusion
Rotating hinged knee prostheses provided good pain relief and stability with acceptably low complication rates given the severity and complexity of cases in which they were used.
