SURGICAL TREATMENT OF OSTEOCHONDRAL LESIONS OF THE KNEE BY MEANS OF MOSAICPLASTY

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Regenerative Medicine

Background:

• Osteochondral lesions of the knee are common and can impair joint function.
• Current treatment options aim to restore the articular surface and improve knee function.

Purpose of the Study:

• To evaluate the functional outcomes of mosaicplasty for treating knee osteochondral lesions.
• To compare the efficacy of mosaicplasty based on lesion location (femoral condyle vs. patella).

Main Methods:

• A cohort of 27 patients with knee osteochondral lesions underwent mosaicplasty.
• Patients were assessed using Lysholm's functional scale pre- and post-operatively.
• Mean follow-up was 2.5 years, with lesion location and size recorded.

Main Results:

• Overall functional scores improved significantly from a mean of 62.7 pre-operatively to 95.4 post-operatively.
• Mosaicplasty yielded excellent results for lateral femoral condyle lesions (mean score 100 post-op).
• Medial femoral condyle lesions also showed substantial improvement (mean 95.4 post-op), while patellar lesions had slightly lower improvement (mean 92 post-op).

Conclusions:

• Mosaicplasty is a viable and effective treatment for knee osteochondral lesions.
• The technique demonstrates superior functional recovery for lesions located on the femoral condyles compared to those on the patella.
