AbstractABSTRACT: BACKGROUND: Osteochndritis Dissecans is relatively rare disorder commonly affect adolescent males, non weight bearing area of the medial femoral condyle is the most common site. OCD is a radiological diagnosis with MRI sensitivity about (97%). Non operative treatment indicated in juvenile form and stable type. Operative intervention indicated in adult form and unstable lesions.
OBJECTIVE: To the postoperative clinical knee functional outcome between arthroscopic screw fixation and arthroscopic subchondral bone drilling in OCD. PATIENTS AND METHODS: A retrospective comparative non randomized study was performed on 10 patient (8 males and 2 females) with adult form of OCD. The patients were divided into 2 groups( A and B), each group consisting of 4 males and 1 female. All patients in group( A) underwent arthroscopic screw fixation, and all patients in group (B) underwent arthroscopic subchondral bone drilling. After 3, 6 and 12 months follow up, the 2 groups were compared preoperative and postoperative according to Lasholm Score changes. RESULTS: In both groups ( A and B), the difference in improvement of the clinical knee outcome postoperatively better than preoperatively according to Lasholm Score( P value less than 0.001) which was statistically significant, and the difference in improvement in group (A) better than in group (B) postoperatively, P value < 0.001 which was statistically significant. CONCLUSION: Arthroscopic screw fixation in OCD has statistically better clinical knee functional outcome than arthroscopic subchondral bone drilling, and it is recommended to do arthroscopic screw fixation if possible. .
