“…This is a prospective cohort study with 1-year follow-up, comparing isometric hip muscle strength between patients with hip dysplasia and healthy volunteers. The study is part of a prospective investigation on the same patient population, reporting pain and ultrasonographic abnormalities in hip muscles and tendons and physical activity level before and after PAO (Jacobsen et al 2018a(Jacobsen et al , 2018b(Jacobsen et al , 2018c(Jacobsen et al , 2019.…”

Background and purpose — In patients with hip dysplasia, knowledge of hip muscle strength after periacetabular osteotomy is lacking. We investigated isometric hip muscle strength in patients with hip dysplasia, before and 1 year after periacetabular osteotomy, and compared this with healthy volunteers. Furthermore, we investigated whether pre- to post-surgical changes in self-reported pain and sporting function were associated with changes in isometric hip muscle strength. Patients and methods — Isometric hip muscle strength was assessed twice in 82 patients (11 men) with a mean age of 30 (SD 9) years, before and 1 year after surgery, and once in 50 healthy volunteers. Isometric hip muscle strength was assessed with a hand-held dynamometer. Copenhagen Hip and Groin Outcome Score was used to measure self-reported outcome. Results — Despite 1-year improvements in isometric hip flexion (0.1 Nm/kg; 95% CI 0.06–0.2) and abduction (0.1 Nm/kg; CI 0.02–0.2), the patients’ muscle strength was 13–34% lower than the strength of the healthy volunteers both pre- and post-surgery (p < 0.01). Moreover, changes in self-reported pain were associated with changes in hip flexion (13 points per Nm/kg; CI 1–26) and abduction (14 points per Nm/kg; CI 3–25), while changes in self-reported sporting function were associated with changes in hip extension (9 points per Nm/kg; CI 1–18). Interpretation — Isometric hip muscle strength is impaired in symptomatic dysplastic hips measured before periacetabular osteotomy. 1 year after surgery, isometric hip flexion and abduction strength had improved but muscle strength did not reach that of healthy volunteers.

“…Compared with THR, PAO is an ideal choice for young people with symptomatic DDH (33,34). Current follow-up results con rmed the e cacy of PAO (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). China was one of the countries to adopt PAO early, but there are few follow-up studies on PAO in the international community.…”

“…PAO not only corrects the lateral, anterior coverage, forward and backward tilt, and inward and outward displacement of the acetabulum but also ensures continuity of the posterior column of the pelvis and provides satisfactory correction of the acetabulum in DDH patients, thereby delaying hip osteoarthritis and THR, rendering it fully applicable to young patients(8). This surgery has been widely used in many countries, and some follow-up results have con rmed the e cacy of PAO (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). China was one of the countries to adopt PAO early, but there are few follow-up studies on PAO, making current PAO studies important.…”

Background Bernese periacetabular osteotomy (PAO) is an effective treatment for patients with developmental dysplasia of the hip (DDH). PAO has been widely used in China, but few follow-up outcomes have been reported in the international community. Moreover, the risk factors affecting patient-reported outcomes have not been discussed in recent studies. In this study, patient-reported outcomes after PAO were reported, and risk factors affecting patient-reported outcomes were analyzed. Methods Patients who underwent PAO for DDH from January 2014 to January 2020 were selected as the study subjects, and 79 hips were included in the analysis after screening (71 patients, with an average follow-up time of 2.98 years). The Harris Hip Score (HHS) and International Hip Outcome Instrument-12 (iHOT-12) were used to assess hip function and patient quality of life. A HHS < 80 was defined as symptomatic hips, that is, an adverse outcome; otherwise, it indicated preserved hips. Multivariate logistic regression analysis was used to predict the risk factors influencing the patient-reported outcomes, and receiver operating characteristic (ROC) curve analysis was performed on the risk factors to determine their sensitivity, specificity and cutoff value. Results Clinical outcome analysis demonstrates marked improvements in patient-reported outcomes. The multivariate logistic regression analysis showed that when the postoperative LCEA was > 38°, adverse outcomes were much more likely. However, a Tönnis angle of -10°-0 was a protective factor. In addition, hips with fair or poor joint congruency were 7.794-fold more likely to develop negative outcomes. The ROC curve analysis showed that the optimal thresholds for the LCEA and Tönnis angles used to predict outcomes after PAO were 38.1° and − 9°, respectively. The patients with a postoperative LCEA < 38.1° had a success rate of 83%. In contrast, the success rate was 32% for patients with a postoperative LCEA > 38.1°. In addition, while the patients with a postoperative Tönnis angle of -9°-0 had a success rate of 70%, and those with a Tönnis angle of 0–10° had a success rate of 65%; the success rate of a Tönnis angle <-9° was only 10%. Conclusions Our results demonstrate marked improvements in patient-reported outcomes. Among hips with preoperative excellent or good joint congruency treated by experienced surgeons who obtain the proper postoperative LCEA and Tönnis angles, good patient-reported outcomes can be expected.

PurposeThe aim of this study was to examine test–retest reliability and responsiveness of the short version (6‐item) Hip Return to Sport after Injury (Hip‐RSI) scale in patients following hip arthroscopy.MethodsThe study included 100 hip arthroscopy patients responding to a digital survey including the short version (6‐item) Hip‐RSI, International Hip Outcome Tool (short version) (iHOT‐12) and RTS status 3, 6 and 9 months following surgery. The Hip‐RSI was administered twice at 3‐month follow‐up. Test–retest reliability was evaluated using intraclass correlation coefficients. Responsiveness was tested by correlations between changes in Hip‐RSI and iHOT‐12 scores and by comparing change in Hip‐RSI scores of patients who progressed on the return to sport (RTS) continuum (from return to any sport to return to performance) to patients who did not, using independent samples t‐tests.ResultsHip‐RSI was found to have excellent test–retest reliability on the individual (intraclass correlation coefficient, ICC [95% confidence interval, CI]: 0.90 [0.83–0.94]) and group level (ICC [95% CI]: 0.95 [0.91–0.97]) with a standard error of measurement of 5.53 and smallest detectable change of 15.3 on the individual and 2.2 on the group level. Hip‐RSI was found responsive to change through positive correlations of changes in scores with changes in iHOT‐12 scores from 3 to 6 months (r [95% CI]: 0.51 [0.35–0.65]; p < 0.001) and from 3 to 9 months following arthroscopy (r [95% CI]: 0.61 [0.57–0.79); p < 0.001). Further responsiveness was shown by significant mean changes in scores among patients that progressed on the RTS‐continuum (3–6 months: 8.6 [95% CI: 3.8– 13.5); 3–9 months: 12.6 [5.6–19.7]).ConclusionThe short version (6‐item) Hip‐RSI demonstrated excellent test–retest reliability and responsiveness to change in the evaluation of psychological readiness to RTS following hip arthroscopy.Level of EvidenceLevel II.
