Abstract:
Limb length discrepancy(LLD) is a common complication after total hip arthroplasty (THA). Good positioning of the prosthesis and suitable soft tissue tension are essential to ensure hip joint stability. Patients will be more satisfied if almost the same length of both lower extremities is achieved. Preoperative comprehensive evaluation of patients is helpful to prevent the occurrence of LLD after surgery. Therefore, the pelvic spine conditions, as well as type and cause of LLD should be analyzed in detail before surgery. During operation, limb length should be adjusted by touching the position of patella, Kirschner's wires positioning and referring to the relationship between the center of femoral head and the tip of greater trochanter. After surgery, it is necessary to clearly distinguish true LLD from functional LLD, and make a reasonable therapeutic plan according to patient's symptoms and the range of differences in limb length. This article reviews the latest literatures based on clinical practice experience and summarizes the research status of LLD after THA, which helps joint surgeons to have an in-depth understanding of this postoperative complication.
