Abstract：Objective To explore the operative method and early clinical results of minimally invasive total hip arthroplasty ( THA ) with supercapsular percutaneously-assisted total hip ( Super PATH ) approach. Methods We retrospectively analyzed 14 patients ( 15 hips ) who underwent minimally invasive THA with Super PATH approach from November 2015 to August 2016. The length of incision, length of hospital stay, operation time, intraoperative blood loss and Harris hip score were observed. Results The average length of incision was ( 7.06 ± 1.05 ) cm, and the average hospital stay was ( 5.7 ± 0.6 ) days. The average operation time was ( 106.0 ± 14.3 ) min, and the average blood loss during the operation was ( 270.6 ± 63.2 ) ml. The Harris hip score was ( 27.9 ± 4.3 ) preoperatively, ( 63.2 ± 5.1 ) at 3 days after the operation, and ( 83.1 ± 5.7 ) at 3 months after the operation. The Harris score of the hip joint gradually increased after the operation, and the differences were statistically significant ( P < 0.05 ). No complications such as incision infection, fracture, deep vein thrombosis ( DVT ), prosthesis dislocation, prosthesis loosening or unequal length of lower limbs were found in the follow-up. Conclusions Early clinical results of minimally invasive THA with Super PATH approach are satisfactory, with the advantages of small incision, quick recovery being less invasire, etc. The postoperative pain, risk of postoperative dislocation and other complications can be significantly reduced, so as to achieve the purpose of rapid recovery. However, the time of clinical application is short, and the medium-long-term results and related complications need to be further observed.
