[Animal experiment studies on the effect of intra-articular injections of antiphlogistic-antirheumatic agents on articular cartilage in vivo].

| Abstract |
Animal experiments have shown that weekly intraarticular injections of various antiphlogistic/antirheumatic drugs into the knee joint induce progressive degenerative alterations in joint cartilage. The observed degenerations and destructions are most similar to the pathophysiology of osteoarthrosis in humans. By X-ray and macroscopic techniques the degenerative processes can be studied qualitatively and quantitatively. A decrease of joint space is a sensitive and early indicator of osteoarthrosis and showed that 10 weeks after intraarticular application of Ibuprofen, Phenylbutazone, Oxyphenbutazone, Flufenamic acid, Niflumic acid, Na-salicylate, Clofezone, Bumadizone and Dexamethasone the degenerative alterations in the injected knee joints were more severe than by applications of Chloroquine,D-penicillamine, Salicylamide and Indometacin. The degenerative effect on articular cartilage by the investigated drugs can be explained by their inhibitory potency on anabolic metabolism of connective tissue. The results of our animal experiments lead to the conclusion, that antiinflammatory drugs may also in man induce or accelerate degenerative joint diseases especially after long term treatment with high doses of these drugs.
