Abstract

Objective: Osteoarthritis (OA) is a major cause of musculoskeletal pain and disability worldwide. The investigation of disease-modifying treatment options for OA has become an important aspect of orthopedic care. To assess the effect of intra-articular and oral glucosamine sulfate (GS) versus placebo on osteoarthritis in a canine model. Materials: In this randomized, placebo-controlled, double-blinded study, OA was induced by anterior cruciate ligament transection (ACLT) according to the Pond-Nuki model in 32 canines. All canines were allocated into 4 treatment subgroups with treatment administered for 8 weeks: GS (400 mg) intra-articular, placebo intra-articular, GS (200 mg/kg body weight) oral, and placebo oral. The contralateral nonoperated stifle (knee) served as control. After 8 weeks, the medial and lateral femoral condyles, the medial and lateral tibial plateau and patella were histologically examined and anatomic changes quantified by light microscopy using the modified Mankin score. Results: After 8 weeks, mean Mankin score values significantly ( P < 0.002) decreased in the intra-articular GS group (8.1; range 7.9-8.8) compared with the intra-articular placebo group (13.9; range 11.6-15.9) and again significantly ( P < 0.002) in the oral GS group (12.1; range 9.9-12.7) compared with the oral placebo group (15.1; range 12.5-17.0). Mean Mankin score values were significantly ( P < 0.002) lower in the intra-articular GS group compared with the oral GS group. Conclusion: Both, intra-articular and oral administered GS significantly reduced histological signs of OA in the Pond-Nuki model, with the intra-articular application being more effective compared to oral administration.
