Spontaneous recurrent hemarthrosis following total knee replacement is a relatively rare complication. It requires a different and swift management plan compared to any other knee swelling. Presentation can vary from 2 months to 1.5 years, and it can lead to further complications, including a limited range of movement and severe stiffness, resulting in compromised functionality. Although etiology is not well understood, it can be due to instrumentation leading to direct vessel injury, including popliteal and geniculate arteries, arteriovenous fistula, and pseudoaneurysms. This case report aims to contribute to the early identification and management of this rare complication. We present a case involving the early onset of recurrent spontaneous hemarthrosis following robot-assisted total knee replacement surgery.
全膝关节置换术后自发性反复关节积血是一种相对罕见的并发症。与其他膝关节肿胀相比，它需要不同且迅速的处理方案。发病时间可从2个月至1.5年不等，并且可能导致进一步的并发症，包括活动范围受限和严重僵硬，从而导致功能受损。虽然病因尚不完全清楚，但可能是由于手术操作导致直接血管损伤，包括腘动脉和膝部动脉、动静脉瘘和假性动脉瘤。本病例报告旨在促进对这种罕见并发症的早期识别和处理。我们报告一例机器人辅助全膝关节置换术后早期发生反复自发性关节积血的病例。
