The majority of research investigating post-corrective complete hip arthroplasty (THA) focussed primarily on the mini-incision approach. Research into the short sparing method of external rotators is unusual. The purpose of this analysis is therefore to compare the efficacy of the posterior standard approach with the short sparing external rotating approach.

This prospective observational study included 126 patients who underwent THA. Patients were assigned to standard (standard posterior approach) and corrective (short external rotator sparing approach) groups based on the surgical method. Surgical data were recorded postoperatively. Postoperative hip joint recovery was assessed using the times to ambulation and independent stair use, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Harris score, and Oxford hip score (OHS) at 2 and 8 postoperative weeks. The visual analog scale (VAS) was used for postoperative pain assessment.

--Postoperative changes of creatine kinase (CK), myoglobin, CRP, and prosthesis position were similar in both groups.
--However, intraoperative blood loss and postoperative 6-h drainage volume, hospital stay, blood transfusion rate, and times to ambulation and independent stair use were significantly reduced in the corrective group.
--Postoperatively, Oxford, and WOMAC scores significantly decreased in both groups. After surgery, the VAS score was more overtly decreased in the corrective group compared with the standard group.

This study concluded that the corrective THA sparing short external rotators could reduce the damage to the nerves and soft tissues, decrease the perioperative blood loss, shorten the functional recovery time, maintain the prosthesis stability, alleviate the hip joint pain, and accelerate the postoperative hip joint recovery, thereby improving short-term patient condition.
