Total hip arthroplasty (THA) in a patient with chronic lymphedema of both lower limbs is rarely reported in the literature. Chronic lymphedema is a challenging condition associated with various complications especially in a patient with THA. However, dislocation of the total hip prosthesis due to acute exacerbation of lower limb swelling in the postoperative period is an extremely rare complication. The cause that led to the dislocation of the prosthesis is intricate and difficult to assess, as this has not been discussed in the literature yet. We believe that the excessive weight of the limb due to chronic lymphedema had a deleterious effect on the biomechanics of total hip prosthesis, thereby increasing the tendency for dislocation. This case illustrates that chronic lymphedema of the lower limb should be dealt with aggressively using various modalities like intermittent pneumatic compression pumps and compression stockings after THA in such patients.
双侧下肢慢性淋巴水肿患者行全髋关节置换术（THA）在文献中鲜有报道。慢性淋巴水肿是一种具有挑战性的病症，会引发各种并发症，尤其是在接受全髋关节置换术的患者中。然而，术后因下肢肿胀急性加重导致全髋关节假体脱位是一种极为罕见的并发症。导致假体脱位的原因错综复杂，难以评估，因为文献中尚未对此进行讨论。我们认为，慢性淋巴水肿导致的肢体过重对全髋关节假体的生物力学产生了有害影响，从而增加了脱位的倾向。该病例表明，对于此类患者，在全髋关节置换术后应积极采用间歇性气动压缩泵和压力袜等多种方式来处理下肢慢性淋巴水肿。
