Abstract
|
|
|
Over the past few years the arthroscope has played a major role in the evaluation and treatment of the chondral and osteochondral lesions of ankle joint. But its technique is very diffiult and require considerable expertise with instrument.
We reviewed 10 ankles in 10 patients who underwent arthroscopic treatment of the osteochondral lesion of ankle at Seoul National University Hospital from 1986 to 1991. The mean age at the time of surgery was 30 years (range, 16 to 49 years).
There
were
eight males and two females. All patients had history of trauma and conservative treatment under the diagnosis of ankle sprain. The mean follow-up was 2 years and 9 months (range, 1 year and 2 months to 6 years and 7 months). Preoperative
diagnosis
were
osteochondritis dissecans in 7 ankles, loose osteochondral body in one and degenerative arthritis in two through CT or MRI. Arthroscopic diagnosis wee osteochondritis dissecans with crater and loose body in 6 ankles, loose osteochondral body with
no
osteochondral defect in one and plsttraumatic degenerative arthritis in three. Six ankles with crater and loose body were treated with arthrosopic abrasion and loose body removal. One ankles with loose osteochondral body was treated with loose
body
removal and 3 ankles with degenerative arthritis were treated with resection of body spure and osteochondral ridge. At last follow up, 8 ankles showed excellent and two showed good result. Postoperatively one patient complained transient dorsal
numbness
and there were no permanent complications.
Arthroscope would play a definite role in the diagnosis and treament of the osteochondral lesions of ankle.
