Background: Osteoarthritis (OA) of knee is common disease; however, the treatment
with conservative method is occasionally not effective. In terms of surgical method,
arthroscopic debridement is one of the most minimum invasive interventions for initial
to moderate OA. In this study, we evaluated the clinical outcome of arthroscopic
debridement / chondroplasty for knee OA. Materials and Method: Thirty-six patients
(9 men, twenty seven women; mean age, 65.5) who suffer from OA of knee
underwent arthroscopic debridement / chondroplasty for the surgical treatment due to
non-response to conservative therapy, including medication and physical therapy.
The mean follow-up period was 8.3 months (3 to18 months) post-operatively. On preoperative
radiographic evaluation, 13 knees showed Grade1, 14 knees indicated
Grade 2, and 9 were Grade 3 with Kellegren-Lawrence Scale. Clinical outcome was
assessed with Japanese Orthopaedic Association Score (JOA score, full mark: 100
points) compared with pre-and post-operative condition, OA grade, and surgical
methods (debridement with or without chondroplasty). Results: In total, mean preoperative
JOA score (62.6 points) was significantly improved compared with preoperative
score (81.5 points) (p
