A Study of Meniscus Injury to Knees in the Elderly

Injuries to meniscus were studied in 31 knees of 30 patients, of which 11 knees were male and 21 were Female Their ages ranged from 65 to 78 years old with an average being 68.9. The following observation were noted:1) Of the 31 knees, 27 were surgically treated under arthroscopy only, and the remaining 4 were with additional intraarticular incision.2) Medial meniscus injury was seen in 24 knees, lateral in 4 knees, and both in 3 knees. Total meniscectomy was carried out in 3 knees, extensive in 13 and partial in 18.3) No obvious correlation between the meniscus injury and the degeneration of articular cartilage was shown.4) Certain correlation between the X-ray findings of Injured Meniscus and the degeneration was noted.5) No correlation between the injury and the difference in body weight or the medial deformity of knee joints was noted.
