Introduction
The purpose of this study was to evaluate the incidence of osteoarthritis ten years after acl-reconstruction. Does acl reconstruction have an influence on osteoarthritis of the knee?
Methods
Between March 1993 and January 1994 53 patients with acl-instability were operated arthroscopically (pbtb) by one surgeon. At minimum 10 year follow up 58% (n=31) were seen. Visual Analog Scale (VAS), clinical examination (IKDC score, Tegner score, Lysholm score, KT-1000 stabilometry) were noted. X-ray evaluation comparing with the contralateral side was performed by two independent examiners.
Results
The overall IKDC-score demonstrated 32% IKDC A , 52% B and 16% C. The KT-1000 revealed 55% A (-1-2mm), 29% B (3-5mm) and 16% C (6-10 mm). The Lysholm-score showed 91 points, the VAS 8,5. Tegner score was pre-op 6.8, post-op 6. Looking at the osteoarthritis rate 55 % decreased one grade according to the Kellgren classification, 32% ¡Y two grades. In 13 % there was no change, compared to the contralateral side. The Fairbank classification showed increase in osteoarthritis in 52% grade 1, 35% grade 2 and 3% grade 3. 10 % had no changes.
Conclusions
10 years after acl-reconstruction more than 60% of the patients showed only a slight increase concerning osteoarthritis. 52% could keep up the level of activity and 6% could even improve it. There was no correlation between the level of activity and occurrence of OA. The long term clinical results of acl-reconstruction are satisfactory, the occurrence of arthritis only minor to moderate based on radiographic criteria and minor based on Visual Analog Scale.
