It is frequently assumed that persisting instability of the knee joint leads to gonarthrosis. We have reviewed recent and primary radiograms of 32 patients with old knee trauma resulting in prolonged capsular and ligamentous instability in order to study the eventual development of secondary gonarthrosis. Our results were as follows: All primarily intact joints developed gonarthrosis after an average of 46 months of permanent instability. Primarily existing gonarthrosis increased with exception of 3 cases. The tendency to develop an arthrosis seems to be proportional to the duration of instability; the type of instability apparently has no influence on the development of an instability gonarthrosis. Operative procedures having been performed prior to final stabilysing surgery obviously do not cause the development of secondary gonarthrosis. The persisting instability of the knee joint after combined discontinuation of capsule and ligaments therefore may be regarded as a prearthrotic factor.
人们常常认为膝关节持续不稳定会导致膝关节炎。我们回顾了32例陈旧性膝关节创伤患者的近期及原始X线片，这些创伤导致了长期的关节囊和韧带不稳定，以研究继发性膝关节炎的最终发展情况。我们的结果如下：所有最初完好的关节在平均46个月的永久性不稳定后都出现了膝关节炎。除3例患者外，最初存在的膝关节炎有所加重。发生关节炎的倾向似乎与不稳定的持续时间成正比；不稳定的类型显然对不稳定型膝关节炎的发展没有影响。在最终稳定手术之前进行的手术显然不会导致继发性膝关节炎的发生。因此，在关节囊和韧带联合中断后膝关节的持续不稳定可被视为关节病前期因素。
