Shaving of the articular cartilage on the undersurface of the patella was carried out in mature white New Zealand rabbits to determine whether the removed cartilage reformed or the shaving led to later evidence of degenerative arthritis. The animals were followed for as long as 15 months after surgery, at which time patellae were removed and examined by light and electron microscopy. The depth of shaving varied considerably; however, no evidence of repair and no evidence of degenerative arthritis was noted in either the superficial or deeply shaved patellae. It is concluded that such superficial cartilage defects neither repair or produce subsequent degenerative arthritis.
在成年白色新西兰兔的髌骨下表面进行关节软骨刮除术,以确定去除的软骨是否会再生,或者刮除是否会导致后期出现退行性关节炎的迹象。术后对动物进行长达15个月的随访,之后取出髌骨,通过光学显微镜和电子显微镜进行检查。刮除深度差异很大;然而,无论是浅刮还是深刮的髌骨,均未发现修复迹象和退行性关节炎迹象。得出的结论是,这种浅表软骨缺损既不会修复,也不会导致后续的退行性关节炎。
