Quantification of papain-induced rat osteoarthritis in relation to time with the Mankin score

Abstract

Objectives: The aim of this study was to evaluate structural changes in relation to time with the use of the Mankin scoring system in papain-induced rat osteoarthritis. Methods: Osteoarthritis was induced in 21 male Wistar rats by injecting an admixture of 4% papain (10 µl) and its activator 0.03 M cycteine (10 µl) into the right knee joints on the first, fourth, and seventh days. The same volume of sterile saline solution was injected into the left knees as controls. The rats were assigned to three groups equal in number and were sacrificed under high-dose ether anesthesia after one, two, and four weeks of the last papain injection, respectively. The study and control knee joints were removed and histologic changes in cartilage structure were assessed and quantified with the modified Mankin scoring system. Results: Histologically, all papain injected knees exhibited irregularity and fibrillation in the superficial layer, decreased cell count and multilayering in transitional and radial zones, and no pannus formation. The modified Mankin scores were significantly higher compared to the control knees in all the groups (p<0.05), being 4.3±0.9, 6.9±1.3, and 10.4±1.9 in diseased knees, and 2.7±0.5, 4.0±0.8, and 4.4±1.0 in the control knees after after one, two, and four weeks of the last papain injection, respectively. There was a significant difference between the Mankin scores of the rats sacrificed after one and four weeks of the last papain injection (p=0.0471). Conclusion: Findings observed after four weeks of papain injection seem to be consistent with early osteoarthritic changes. Our results may provide insight into therapeutic strategies for early osteoarthritis.
