Between July 1989 and 1994 127 Baker-cysts have been operated and histologically examined with synovial biopsies out of the same knee. All Baker-cysts and synovial biopsies - including out of synovial membranes without macroscopically pathological findings and without other pathological intraarticular causal lesions - revealed a chronic synovitis. The Baker-cyst has to be regarded as a primary or secondary causative factor of chronic effusions and involves the development of a chronic synovitis by the disorder of the synovial and hydraulic system of the knee-joint. The exstirpation of the Baker-cyst as a prearthrotic factor is advised therefore.
1989年7月至1994年间，对127个腘窝囊肿进行了手术，并对同一膝关节的滑膜活检组织进行了组织学检查。所有腘窝囊肿及滑膜活检组织——包括肉眼无病理发现且无其他关节内病理性病因病变的滑膜组织——均显示为慢性滑膜炎。腘窝囊肿应被视为慢性积液的原发性或继发性病因，并且通过膝关节滑膜和液压系统紊乱导致慢性滑膜炎的发展。因此，建议将切除腘窝囊肿作为关节病前期因素。
