Introduction
The replacement of the medial compartment with the AMC-Uniglide prosthesis is possible through a small incision.
Has mini-invasive implantation a faster rehabilitation?
Exist differences in the clinical and radiological outcome by comparison to the standard open technique?
Method
We followed and compared the outcome of 30 mini-invasive implanted prosthesis with 30 unicompartmental arthroplasties in standard open technique and 30 total knee arthroplasties. The rehabilitation time was measured for straight leg raising, knee flexion 90° and stair climbing.-The postoperative x-rays of both UCA groups were analyzed. Ten criteria were assessed at femur and tibia with a scoring system.-The knee and function score according to the Knee Society Rating System were registered preoperative and six months postoperative.
Results
The mini-invasive group required 50% of the time, the standard implantation collective 75% of the time which was needed by the total knee arthroplasties. The analysis of the x-rays showed very similar results.
The Knee and Function Scores after 6 months gained equal progressivity in points.
Discussion
Mini-invasive implantation of the AMC-Uniglide prosthesis accelerates rehabilitation considerable in comparison to standard open technique.
The analysis of the postoperative x-rays showed comparable good results for both UCA groups. This indicates that the instrumentation of the AMC-Uniglide enables a similar precise implantation for the mini-invasive technique as for standard open approach.
The clinical and functional results six months postoperative are equally good for both collectives.
