The study on the dislocation rate at 1 year after SuperPATH primary total hip arthroplasty showed no dislocations, low blood transfusion rate, and most patients discharged home within 2.3 days post-operation.
BackgroundDislocation after primary total hip arthroplasty (THA) has an incidence of 2-3%. Approximately 77% of dislocations occur within the first year after surgery. The SuperPATH technique is a minimally invasive approach for THA that preserves soft tissue attachments. The purpose of this study is to describe the dislocation rate at 1 year after SuperPATH primary THA.MethodsAll elective primary THAs performed by the senior author using the SuperPATH approach. Exclusion criteria were acute femoral neck fracture, revision surgery, or malignancy. There were 214 of 279 eligible patients available for telephone interviews (76.7%). Medical records were reviewed for secondary outcomes including early and late complications, cup positioning, distance ambulated on postoperative day one, discharge destination, and blood transfusions.ResultsMean age at surgery was 6410.8years and mean time to telephone follow up was 773 +/- 269.7days. There were 104 female and 110 male patients. There were zero dislocations reported. Blood transfusions were performed in 3.7% of patients, and 75.7% were discharged to home at an average of 2.3 +/- 1.0days. Cup position averaged 43.6 +/- 5.2 degrees abduction and 20.9 +/- 6.2 degrees anteversion, with an average leg length discrepancy of 3.6 +/- 3.32mm. Complications included three intraoperative calcar fractures, one periprosthetic femur fracture, one early femoral revision, three superficial infections, and one instance of wound necrosis.Conclusion SuperPATH approach is safe for use in primary THA resulting in a low dislocation rate.
