This study retrospectively investigated 192 teenage speed and figure skaters with prior injuries documented by an athletes’ questionnaire, who underwent a physical examination to assess their muscle tightness and generalized joint laxity. In all athletes, the degree of muscle tightness and joint laxity were measured by a standardized physical examination. A descriptive report of the types of injuries showed a predominance of fractures, ligament injuries, enthesitis, and lower back pain. Approximately 5% of all skaters tested positive for tightness, while 25.8% of figure skaters and 15.2% of speed skaters had generalized ligamentous laxity. Statistical testing showed an association between ankle sprains and muscle tightness, and an association between knee enthesitis and muscle tightness in skating athletes. There was also an association between lower back pain and generalized joint laxity, which held true only for the male skaters.

“…Patients were excluded if they had: a history of ACL reconstruction; history of contralateral ACL injury; history of meniscus surgery; history of injuries such as muscle strains, sprains, tendinopathy, or fracture that affected physical function in the lower back or lower limb after reconstruction or within the 6 months preceding reconstruction; history of reconstruction for other knee ligaments in addition to the ACL; hope to return to snow and ice sports such as skiing or ice hockey; no participation in sports after reconstruction for social reasons such as relocating or becoming pregnant; experience of comorbidities that hindered the return to sports; or inability to complete the ACL‐RSI and physical function tests on the same day between 170 and 240 days after reconstruction [ 14 ]. Patients wishing to return to snow and ice sports were excluded because these sports involve distinctly different surfaces, shoes, and injury mechanisms such as slip‐catch while skiing and involvement of centrifugal force during figure skating [ 15 , 16 ].…”

PurposeThis study aimed to investigate the intricate relationship between physical function factors and each subcategory score of the Anterior Cruciate Ligament‐Return to Sport after Injury (ACL‐RSI) scale among patients following ACL reconstruction.MethodsParticipants comprised 59 patients who had undergone primary ACL reconstruction using hamstring tendon. The ACL‐RSI was completed 6 months after reconstruction and five physical functions were measured in patients on the same day. Simple linear regression was performed multiple times to investigate the relationship between ACL‐RSI subcategory scores as a dependent variable and each independent variable (knee strength, leg anterior reach distance, single‐leg hop [SLH] distances, side bridge endurance, and subjective running ability). Multiple regression analysis was performed using a stepwise method, with factors showing a risk rate <0.05 in simple linear regression analyses as independent variables and the ACL‐RSI in each subcategory score as the dependent variable.ResultsMultiple regression analysis showed that subjective running ability affected all subcategories (p ≤ 0.001), and that the limb symmetry index of medial SLH distance affected both the Emotions (p = 0.047) and Confidence (p = 0.009) subcategories. Higher subjective running ability and greater limb symmetry in the medial SLH were thus positively associated with each dimension of psychological readiness.ConclusionsThis study highlights the differential impact of physical function factors on specific subcategories of the ACL‐RSI scale, providing clinicians with insights for designing targeted rehabilitation strategies. This original paper suggests the importance of analysing factors related to subcategory scores in addition to total ACL‐RSI score, and could contribute to the understanding of determinants for a successful return to sport following ACL reconstruction.Level of EvidenceLevel IV.

Background Information about specific factors of physical function that contribute to psychological readiness is needed to plan rehabilitation for a return to sports. The purpose of this study was to identify specific physical functions related to the psychological readiness of patients aiming to return to sports 6 months after reconstruction. We hypothesized that the knee strength is a factor related to the Anterior Cruciate Ligament–Return to Sport after Injury scale (ACL-RSI) cutoff score for a return to sports. Methods This was a cross-sectional study. Fifty-four patients who had undergone primary reconstruction using hamstring tendon participated in this study. Psychological readiness was measured using the ACL-RSI in patients at 6 months after reconstruction. To identify specific physical functions related to the ACL-RSI score, participants were divided into groups with ACL-RSI scores of ≥ 60 or < 60. Non-paired t-tests or the Mann–Whitney test were performed to analyze group differences in objective variables in physical function: (1) knee strength in both legs; (2) leg anterior reach distance on both sides; and (3) single-leg hop (SLH) distances in three directions for both legs. Results Significant differences between groups were identified in knee flexion strength (60°/s) for the uninvolved limb, hamstring-to-quadriceps ratio (60°/s) for the uninvolved limb, knee flexion strength (180°/s) for the involved limb, limb symmetry index (LSI) of leg anterior reach distance, the ratio of the distance to the height of the patient and LSI of SLH distances in lateral and medial directions. Conclusion This study revealed that at 6 months after reconstruction, increased knee flexion strength (ratio of peak torque measured to body mass of the patient), hamstring-to-quadriceps ratio, leg anterior reach distance LSI, and lateral and medial SLH appear important to exceed the ACL-RSI cutoff for a return to sports. The present results may be useful for planning post-operative rehabilitation for long-term return to sports after reconstruction.
