Abstract Background: Most of the studies assessing the corrective posterior total hip arthroplasty (THA) mainly focused on the mini-incision approach. Studies exploring the short external rotator sparing approach are rare. Therefore, this study aimed to compare the effectiveness of standard posterior approach and short external rotator sparing approach.Methods: This prospective observational study included 126 patients who underwent THAin 06/2017-06/2018. 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.Results: Postoperative changes of creatine kinase (CK), myoglobin, CRP, and prosthesis position were similar in both groups (P > 0.05). However, intraoperative blood loss (P < 0.001) and postoperative 6-hour drainage volume (P = 0.03), 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.Conclusions: This study concluded that the less invasive short external rotator sparing approach for THA caused less damage, reducing perioperative blood loss, shortening functional recovery time, maintaining prosthesis stability, and improving postoperative pain.

Abstract Background Studies assessing corrective posterior total hip arthroplasty (THA) mostly focused on the mini-incision approach, with few exploring the short external rotator sparing approach. This study aimed to compare the effectiveness of standard posterior approach versus short external rotator sparing approach. Methods This prospective observational study included patients treated in the Orthopedics Department of Jinhua Central Hospital in 06/2017-06/2018. Patient grouping was based on the surgical methods. Surgical data were recorded postoperatively. Postoperative hip joint recovery was assessed by the times to ambulation and independent stair use, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and Harris score and Oxford hip score (OHS) at 2 and 8 postoperative weeks. The visual analog scale (VAS) was used for postoperative pain assessment. Results 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, and blood transfusion rate were significantly reduced in the corrective (short external rotator sparing) group, as well as times to ambulation and independent stair use. Oxford and WOMAC scores in both groups decreased significantly postoperatively. The VAS score was more overtly decreased postoperatively in the corrective group compared with the standard group. Conclusions The corrective THA causes less damage and reduces perioperative blood loss, shortening functional recovery time, maintaining prosthesis stability and improving pain postoperatively.

ObjectiveFemoral offset (FO) restoration is significantly correlated with functional recovery following total hip arthroplasty (THA). Accurately assessing the effects of FO changes on hip muscles following THA would help improve function and optimize functional outcomes. The present study aimed to (1) identify the impact of FO side difference on the hip muscle moment arms following unilateral THA during gait and (2) propose the optimal FO for a physiological hip muscle function.MethodsIn vivo hip kinematics from eighteen unilateral THA patients during gait were measured with a dual-fluoroscopic imaging system. The moment arms of thirteen hip muscles were calculated using CT-based 3D musculoskeletal models with the hip muscles’ lines of actions. The correlation coefficient (R) between FO and hip muscle moment arm changes compared with the non-implanted hip was calculated. We considered that the FO reconstruction was satisfactory when the abductor moment arms increased, while the extensor, adductor, and flexor moment arms decreased less than 5%.ResultsA decreased FO following THA was significantly correlated with a decrease of the abductor and external rotator moment arms during the whole gait (R &gt; 0.5) and a decrease of extensor moment arms during the stance phase (R &gt; 0.4). An increased FO following THA was significantly associated with shorter flexor moment arms throughout the gait (R &lt; −0.5) and shorter adductor moment arms in the stance phase (R &lt; −0.4). An increase in FO of 2.3–2.9 mm resulted in increased abductor moment arms while maintaining the maximum decrease of the hip muscles at less than 5.0%.ConclusionAn increase of 2–3 mm in FO could improve the abductor and external rotator function following a THA. Accurate surgical planning with optimal FO reconstruction is essential to restoring normal hip muscle function in THA patients.
