Abstract
Short-stem hip prostheses were developed to treat active patients requiring total hip arthroplasty (THA). This study provides short-term data about a short-stem total hip arthroplasty system. Functional and radiological outcomes as well as return to sports and activity level were assessed. A series of 55 patients was primarily included. Data were available for 47 patients at an average follow-up of 38 ± 4.6 months. The back-to-sports analysis showed a 98% return-to-sports rate (46/47 patients). The average time for return to sports was 13 weeks (± 8) postoperatively. Five patients (10.6%) were more active postoperatively. The Harris Hip Score (HHS) improved from 34.8 (±9.4) preoperatively to 94.7 (±8.4, p ≤ 0.001) and the University of California, Los Angeles (UCLA) score improved from 4.5 (±1.8) to 6.9 (±1.9) (p ≤ 0.001). The High Activity Arthroplasty Score (HAAS) was 12 (±3.6) at 3-year follow-up. Pre- and postoperative UCLA and postoperative HHS and HAAS scores had a positive influence on the return-to-sports rate (p ≤ 0.05). The collection of radiographic data during all postoperative follow-ups showed no signs of radiolucent lines or bone fissures. The complication rate was at 5%. Short-stem systems are equaling conventional prostheses and offer benefits regarding soft tissue and bone stock preservation. Fast recovery and return to sports can be achieved.
Highlights
With the increasing number of young and active patients who meet the indication for total hip arthroplasty (THA) due to osteoarthritis of the hip joint, as well as precipitating pathologies such as post-traumatic osteoarthritis, avascular necrosis, hip dysplasia and rheumatoid arthritis [1,2,3], minimally invasive and muscle-sparing surgical approaches for THA are being constantly enhanced
We report on the outcome of 55 MiniMIS® (Falcon Medical) short stems with average follow-up of 38 months (±4.6)
One female patient was not able to participate in physical activity because of a persistent intraoperative lesion of the femoral nerve
Summary
With the increasing number of young and active patients who meet the indication for total hip arthroplasty (THA) due to osteoarthritis of the hip joint, as well as precipitating pathologies such as post-traumatic osteoarthritis, avascular necrosis, hip dysplasia and rheumatoid arthritis [1,2,3], minimally invasive and muscle-sparing surgical approaches for THA are being constantly enhanced In consideration of this emerging necessity, short-stem prostheses have been introduced for improved biomechanical reconstruction in the proximal femur, reduced stress shielding, and bone preservation in case of revision surgery at a later time [4]. With the increasing awareness of social and health benefits from regular physical activity, as well as rising expectations of postoperative sports participation, the need for “return-to-sports” education and recommendations should be addressed
