Abstract: BACKGROUND:
Surgical treatment of femoroacetabular impingement is becoming accepted
worldwide, owing to improvements in clinical results and quality of life. In
addition to treatment by surgical dislocation or arthroscopy, arthroscopic
assisted mini-open approach was postulated to treat this pathology.
OBJECTIVE:
The aim of this study was to analyze early results of the first consecutive
72 cases of femoroacetabular impingement treated using the arthroscopic
assisted mini-open approach in two different centers by two surgeons trained
by a senior surgeon experienced in the technique.
METHODS:
Seventy-two consecutive cases of femoroacetabular impingement were operated in
arthroscopic assisted mini-open approach technique in two different centers.
After a mean follow-up time of 15 months (range 6-24 months), the Western
Ontario and McMaster Universities Arthritis Index, Hip disability and
Osteoarthritis Outcome Score and University of California, Los Angeles
activity score, alpha angle and Wiberg angle were obtained.
RESULTS:
In both centers, all three scores showed significantly better results at
follow-up time than preoperatively. The Western Ontario and McMaster
Universities Arthritis Index increased from 64.3 to 91.4 (A) and from 68.1
to 89 (B). The Hip disability and Osteoarthritis Outcome Score increased
from 59.5 to 94.4 (A) and from 62.1 to 93.8 (B). The University of
California, Los Angeles activity score increased from 5.2 to 8.1 (A) and
from 5.3 to 8.4 (B). The alpha angle and the Wiberg angle were significantly
reduced after osteoplasty. The overall complication rate was low.
CONCLUSIONS:
Early results of this study show a good clinical and radiological outcome;
therefore, the arthroscopic assisted mini-open approach can be used as an
alternative in treating femoroacetabular impingement.
