Experimentally Induced Degenerative Joint Lesions Following Partial Meniscectomy in the Rabbit

Abstract

Abstract Degenerative lesions characterized by osteochondrophyte spur formation and cartilage degeneration were induced by partial meniscectomy in the rabbit knee. Cartilage degenerative lesions included ulceration, fissure and cyst formation, and diminished concentration of matrix proteinpolysaccharide. Proliferation of chondrocytes represented efforts at repair. Osteophytes increased in size with time. Changes resembled certain components of degenerative joint disease. The partial meniscectorny animal may be useful in studies of osteoarthritis pathogenesis, pathology and treatment.
