The rehabilitation of patients for total hip arthroplasty is unsatisfactory, especially the prolonged rehabilitation.
To explore indications and key points of anterolateral minimally-invasive total hip arthroplasty.
110 patients admitted for unilateral total hip arthroplasty were randomly selected for surgery with either anterolateral minimally-invasive incision or standard posterolateral incision. Demographic data, perioperative index and postoperative function index were recorded and statistically analyzed.
No significant difference was detected in operation time, abduction angle, anteversion angle, stem alignment and stem fixation. The incision length, blood loss, perioperative transfusion and 100-mm VAS score at the first 24 h in minimally-invasive group were significantly lower. The Harris hip score and Barthel index were significantly higher in minimally-invasive group at 3 months' follow-up, but not significantly different 3 years after operation.
There are fewer traumas, fewer blood losses and more rapid recovery in this approach.
