Prior leg length discrepancy in total hip arthroplasty patients causes greater implant complications and faster time to revision

LLD in patients having THA is related with significantly higher fall risk, rates of implant-related complications, LOS, and quicker time to revision. Identifying patients with LLD before their THA may help in identifying risks, better patient counselling, and more effective preoperative planning. However, the study have important limitations: Its design lacks information on the degree and cause of LLD, the time between diagnosis and surgery, and which leg with the discrepancy underwent the operation. Future well-designed studies should confirm the findings of this study.
