Seventy-three knees of 59 patients (51 female, 8 male) were operated on since 1988. The age at operation ranged from 70 to 92 years old (average 74 years) . Follow-up periods ranged from 6 to 116 months (average 36.7 months) . Results were investigated using standing A-P radiographs. Preoperative status was classified in 4 stages.
For most of the patients, MRI was taken before surgery.
All patients were clinically evaluated by JOA score (Japanese Orthopaedic Association score), and patients' satisfaction.
Result; 1. 63% of patients had complained of acute or subacute gait disturbance. 2. Radiographic findings showed that 80% were unchanged and 20% were worse after surgery. 3. Types of meniscal tears were mostly transverse tears, L shaped flap tears, horizontal tears, and mixed. 4. Average JOA score significantly improved from 44 to 85 points, and 90% of patients were satisfied with their post-operative results.
Conclusion; We conclude that arthroscopic meniscectomy in aged patients provided satisfactory clinical results.
