Chronic Non-Specific Tenosynovitis With Effusion About the Ankle

This is the authors' abstract. We don't add key points for this paper.

In chronic non-specific tenosynovitis with effunsion, localized at the ankle, the symptoms may be present intermittently and the true nature of the condition may remain unrecognized for months or even years. In two of the cases reported, the posterior tibial sheath was involved, and in one, the flexor hallucis longus (in back of the ankle). Erosion of the tibia and talus was present in Case 2, probably secondary to inflammation of the posterior tibial sheath. This patient also had pain in various joints; and, about four years after the operation, bloody effusion developed in the knee on the same side. Local symptoms were relieved in all three cases after removal of the synovial tendon sheath.
