This study aims to establish the midterm safety and performance for the direct superior approach to minimally invasive surgery total hip arthroplasty (MIS-THA). We used a unicentric, single-surgeon, retrospective, consecutive case series analysis of the first 40 patients who received primary unilateral direct superior MIS-THA. Special attention was given to functional recovery by measuring Harris Hip Score (HHS) and timed-up-and-go (TUG) with a mean follow up of 2.2 ± 0.4 years. A radiologic evaluation was performed. HHS and TUG improved significantly at three months and one year (p < 0.001). All components were placed within the Lewinnek safe zone with no change position or signs of loosening at two years. With a minimum of two years of follow up, the direct superior approach appears to be safe without any obvious or consistent postoperative complications-clinically or radiographically-with excellent functional recovery. Additionally, our subgroup analysis supported no late learning curve effect. |
