Prospective Short-Term and Return-to-Sports Results of a Novel Uncemented Short-Stem Hip Prosthesis with Metaphyseal Anchorage

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.

Amount and type of physical activity and sports from one year forward after hip or knee arthroplasty—A systematic review

“…Thirty-one articles reported on activity using one-item questionnaires that give a general indication of activity [ 23 , 26 , 36 , 37 , 41 , 44 , 47 – 49 , 51 , 57 , 61 , 64 , 67 , 71 , 75 , 85 , 90 , 93 , 94 , 103 , 107 , 110 , 114 , 115 , 123 , 126 , 128 , 136 , 138 , 139 ]. On the University of California Los Angeles activity score (UCLA) questionnaire, 21 articles reported a score between 5.5 and 7, which means regular participation in moderate activities.…”

“…Sports participation was reported in eleven articles: in nine participation rates varied between 64% to 91% and two articles reported lower percentages [ 29 , 37 , 47 , 57 , 83 , 93 , 94 , 110 , 125 , 126 , 136 ]. Hara et al [ 47 ] reported that 30.5% participated in sports, while Madrid et al [ 83 ] reported 7.1% institutionalized sport participation.…”

Types of implants and evaluation of quality of life in knee replacement patient

“…High-Activity Arthroplasty Score was designed to detect subtle variations in physical function of highly functioning patients [3].…”

Return to Sports and Return to Work After Total Hip Arthroplasty

“…Several studies have evaluated return to work (RTW)/return to sports (RTS) after THA [7][8][9][10][11][12][13][14][15][16][17][18][19][20] . Despite being informative, these studies focus on specific populations, making their conclusions nongeneralizable.…”

“…Although their search provided extremely useful and valuable findings, it was limited to studies published until October 2017. These topics have been the subject of several studies since then [7][8][9][10][11][12][13][14][16][17][18][19][20] . Moreover, although the authors were the first to systematically describe prognostic factors for RTW/RTS, no analysis was conducted to determine whether patientrelated variables might explain some of the variations in the results.…”
