This study examined the relationship between participation restrictions in activities of daily living and sports following anterior cruciate ligament reconstruction (ACLR) and the status of knee structures, performance-based activity limitations, and impairments. Fifty subjects (36 men, 14 women, age=20.6±1.3 years) at a mean of 31.0±16.3 months following ACLR participated in this study. Participation restrictions in activities of daily living and sports were measured by the combined scores of the Knee Outcome Survey Activities of Daily Living Scale and Sports Activity Scale. The status of knee structures was assessed by determining the number of previously injured structures in the knee and the time from the most recent ACLR to testing. Performance-based activity limitations were assessed with the single leg hop for distance test. Impairments included isokinetic quadriceps function and anterior tibiofemoral joint laxity. Forward stepwise regression analysis revealed that while the number of injured knee structures alone accounted for 47% of the variability in patient-reported participation restrictions, the combination of the number of injured knee structures, time from ACLR, and the hop index provided the most effective es-timate of participation restrictions. Isokinetic quadriceps function and KT-1000 side-to-side differences were not entered into the regression model and were not significant predictors of participation restrictions. We recommend that clinicians use caution in assuming that isokinetic quadriceps function and anterior tibiofemoral joint laxity provide an effective estimate of participation restrictions.

The World Health Organization's most recent version of the International Classification of Impairments, Disability and Handicaps categorizes disablement into physical impairments, activity limitations, and participation restrictions 41]. This biopsychosocial model represents the integration of the medical and social approach to human functioning and disablement. Similar to Nagi's [30] disablement scheme, a physical impairment can result from dysfunction and/or structural abnormality of a specific body system, such as the musculoskeletal system. Limitations in activity, according to the International Classification, refer to the nature and extent of an individual's function as a consequence of pathology or impairment. Limitations of activities may include restrictions in activities of daily living (ADL), such as ambulation and climbing stairs, or limitation in sports, such as running, cutting, and pivoting. The term participation refers to a person's involvement in basic areas of human life, such as self-care, work, sports, and recreation [41]. This classification scheme Abstract This study examined the relationship between impairment of the knee and activity restriction during activities of daily living and sports following anterior cruciate ligament reconstruction. Knee range of motion, swelling, pain, instability, ligamentous laxity, isometric and isokinetic muscle function and performance-based measures of activity restriction were measured in 44 subjects. Four measures of patient-reported activity restrictions, including the Activities of Daily Living, Sports Activities Scales of the Knee Outcome Survey, and global ratings of function during activities of daily life and sports, were statistically combined to create a composite variable representing the level of patient-reported activity restrictions for each subject. Hierarchical regression analysis revealed that 17% of the variability in patient-reported activity restrictions was accounted for by age, length of postoperative followup, and mechanism of injury. Addi-tion of the one-legged hop, Lachman, anterior drawer, and varus stress tests accounted for an additional 40% of the variability of function. When pain and giving way were added to the model, 79% of the variability was explained.

Introduction: The ACL injury has commonly occurred in a greater number of athletes, less publication is about poor knee function and ACL injury in the patient with non-operative treatment. This study aimed to describe the characteristics of patients with ACL injury non-operative, which are associated with poor knee function on daily living activities. Methods: We included patients with ACL injury that has been diagnosed for ACL injury by an orthopedic surgeon or physiotherapist in a hospital or private clinic. All participants were recruited from February 2019 to April 2019. The inclusion criteria were patients who at least 18 years old. We used the KOOS ADL function cutoff score ≤80 to dichotomous the patient with knee problems, and score >80 have no statistical analysis problem. We calculated using binary logistic regression on the KOOS ADL function for each variable. Results: The mean score of KOOS daily living was 72.8 points, of which 66 participants had poor scores, and 37 were acceptable. Women were 9.2 times more likely to had poor KOOS daily living scores than men in non-operative ACL injury patients (p=0.044), and non-elite athletes had a higher possibility by 8.5 times higher than those who were participated in sports only for leisure or recreation (p=0.002). Conclusion: This study confirmed that patients who did not undergo the ACL reconstruction had a poor knee function in daily living. It was associated with women and non-elite athlete participants, yet the concomitant injuries were possibly confounder for the association.

Introduction. The goal of this study was to examine the nature and presence of influence of different levels of sports activity on the life quality of the patients a year after the reconstruction of anterior cruciate ligament. Material and Methods. The study included 185 patients operated at the Department of Orthopedic Surgery and Traumatology of the Clinical Centre of Vojvodina, who were followed for twelve months. Data were collected using the modified Knee Injury and Osteoarthritis Outcome Score questionnaire which included the Lysholm scale. Results. This study included 146 male and 39 female subjects. The reconstruction of anterior cruciate ligament was equally successful in both gender groups. In relation to different types of sports activity, there were no differences in the overall life quality measured by the questionnaire and its subscales, regardless of the level (professional or recreational). However, regarding the level of sports activities, there were differences amo...

Objective: To validate the Knee injury and Osteoarthritis Outcome Score (KOOS) for the assessment of competitive athletes with higher level sports activities after anterior cruciate ligament (ACL) reconstruction. Methods and Measures: Fifty-seven athletes (39 males and 18 females; age, 25.6 AE 3.4 years; height, 179.6 AE 7.4 cm; weight, 77.6 AE 9.8 kg) after ACL reconstruction were asked to complete the Persian KOOS and Short Form-36 (SF-36) questionnaires in the test session. To evaluate testeretest reliability, all participants filled out the KOOS and SF-36, 6e8 days after the first visit. The properties of the KOOS in terms of reliability [Intraclass Correlation Coefficient (ICC)], internal consistency (Cronbach's alpha), dimensionality (itemescale correlation) and construct validity (Spearman's rank correlation) were evaluated. Results: No floor or ceiling effect was observed. The ICCs (S.E.M.s) of the KOOS subscales were: Pain 0.93 (2.2), Symptoms 0.85 (3.1), Activities of Daily Living 0.91 (2.9), Function in Sport and Recreation 0.75 (2.1) and Knee-related Quality of Life 0.89 (2.6). The Cronbach's alphas of the KOOS subscales were: Pain 0.91, Symptoms 0.75, Activities of Daily Living 0.96, Function in Sport and Recreation 0.86 and Knee-related Quality of Life 0.74. Spearman's rank correlations between the subscales of the KOOS and representative subscales of the SF-36 ranged from 0.40 to 0.79. Conclusion: This study illustrates the validity and reliability of the KOOS in measuring the functional status and quality of life of athletes after ACL reconstruction. This study further validates the use of the KOOS in highly competitive athletes in research on knee injuries.

Anterior cruciate ligament (ACL) reconstruction (ACLR) is the most commonly used method for helping athletes regain function and return to preinjury activity levels after ACL injury. Outcomes after ACLR have suggested that athletes return to a level of function that would support a return to sport participation; however, in a recent meta-analysis, pooled return rates were only 55%. It is unclear whether this discrepancy is a result of functional impairments. To compare patient-reported outcomes (PROs), dynamic balance, dynamic functional performance, strength, and muscular endurance in athletes who returned to sport (RTS) and athletes who did not return to sport (NRTS) after ACLR. Case-control study. University research laboratory. Two groups of participants with primary unilateral ACLR: 18 RTS individuals (7 males, 11 females; age = 23 ± 11 years, height = 163.58 ± 40.41 cm, mass = 70.00 ± 21.75 kg, time since surgery = 4.02 ± 3.20 years) and 12 NRTS individuals (5 males,...

Background: The Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) scale is a reliable and valid tool for evaluation of psychological readiness to return to sport after ACL injury, but its responsiveness to change has not been extensively evaluated. Purpose: To determine the responsiveness of the ACL-RSI scale. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: The ACL-RSI scale and the knee confidence question from the Knee injury and Osteoarthritis Outcome Score–Quality of Life subscale was completed at 6 and 12 months after ACL reconstruction surgery. Responsiveness was assessed using distribution and anchor-based methods for the full- and short-form versions of the scale and subgroup analyzed for sex. From distribution statistics, the standardized response mean (SRM) and the smallest detectable change (SDC) were calculated. Using the anchor-based method, the minimally important change (MIC) that was associated with an improvement in knee confid...

Introduction Anterior cruciate ligament (ACL) tears are common injuries that can considerably impact an individual's quality of life and athletic performance. In these cases, surgical reconstruction of the ligament can be considered to restore stability to the knee. This study aims to investigate the time taken for individuals to return to sport post-ACL reconstruction, assess the rate of re-injury and evaluate the reliability of the International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) scoring systems in predicting a return to sport at the pre-injury level. Methods In this retrospective study, a total of 104 patients who underwent ACL reconstruction between January 2016 and December 2022 by one surgical team at Mater Dei Hospital, Malta were evaluated using a selfadministered questionnaire. The questionnaire was based on different components including the sport practised at the time of injury, sport engagement classification, return to sport, the ability to return to preinjury levels of performance and re-injury. The participants then had to fill in IKDC and KOOS evaluation forms. Results In this study, 73% (n=76) of individuals successfully returned to sport after ACL reconstruction, with no significant difference being found between professional and recreational athletes (Chi-squared=0.00455, p=0.95). After reconstruction, 31.7% (n=33) of participants experienced an ipsilateral or contralateral ACL tear, with those returning to sport within six months showing a fivefold increase in re-injury risk compared to individuals who returned at eight or 12 months, suggesting a significant association between return duration and re-injury. The relationship between scoring systems and return to sport at the pre-injury level of performance was analysed using binary logistic regression, revealing that achieving scores of 85.6 or higher in IKDC or 89 or higher in KOOS meant having a 95% probability of returning to sport at the preinjury level. Conclusions By considering these scoring systems with other post-operative criteria, clinicians can offer a more customised rehabilitation plan tailored to each patient who undergoes ACL reconstruction.
