Poly-L-lactic acid (PLLA), a biodegradable polymer, is generally considered to be gradually degraded without causing any severe tissue reaction. However, we encountered a patient who developed foreign body gonitis caused by screw breakage after fixation of an intercondylar prominence fracture with PLLA screws. This case suggests that care should be taken when PLLA materials are used to fix intraarticular fractures.
聚左旋乳酸（PLLA）是一种可生物降解的聚合物，通常被认为会逐渐降解而不会引起任何严重的组织反应。然而，我们遇到了一名患者，在用PLLA螺钉固定髁间隆起骨折后，因螺钉断裂引发了异物性滑膜炎。该病例表明，在使用PLLA材料固定关节内骨折时应谨慎。
