“…In another study examining the measurement properties of a hop test, Reid and colleagues reported mean LEFS scores of 66.0 for 23 men and 64.2 for 19 women at 16 weeks, and of 69.3 for men and 68.8 for women at 22 weeks, after ACL reconstruction. 12 The mean age of Reid and colleagues' sample was 25.6 (range 15-45) years. Their reported values are also similar to the modelled values obtained in our study.…”

“…However, our modelled LEFS curve is supported to the extent that its estimated values are similar to the results reported by Alcock and colleagues 1 and Reid and colleagues. 12 A third limitation is that for reasons of feasibility, we modelled recovery to 26 weeks after reconstruction and not beyond. We therefore cannot comment on what happens after 26 weeks, but our models suggest that while pain and ROM have essentially plateaued by this point, functional status appears to be still increasing.…”

Purpose: To model how patients' knee range of motion (ROM), pain, and self-reported lower-extremity (LE) functional status change over the first 26 weeks following anterior cruciate ligament (ACL) reconstruction and to estimate the test-retest reliability of these measurements. Methods: Patients were assessed weekly over 26 weeks following ACL reconstruction. Outcomes were knee ROM, LE functional status measured by the Lower Extremity Functional Scale (LEFS), and pain measured by the 4-item pain intensity measure (P4). A nonlinear model was applied to describe change for each outcome. Intra-class correlation coefficients and standard errors of measurement were applied to estimate test-retest reliability and minimal detectable change. Key Words: knee; outcome assessment; prognosis; reproducibility of results. RÉ SUMÉObjet: Modé liser comment l'amplitude du mouvement (ADM) du genou des patients, la douleur et l'é tat fonctionnel autodé claré des membres infé rieurs (MI) changent au cours des 26 premiè res semaines suivant la reconstruction du ligament croisé anté rieur (LCA) et estimer la fiabilité de test-retest de ces mesures. Mé thodes: On a é valué les patients une fois par semaine pendant les 26 semaines qui ont suivi une reconstruction du LCA. L'ADM du genou, l'é tat fonctionnel des MI mesuré en fonction de l'é chelle fonctionnelle des membres infé rieurs (EFMI) et la douleur mesuré e par le questionnaire sur l'intensité de la douleur à quatre questions (P4) ont constitué les ré sultats. Nous avons appliqué un modè le non liné aire pour dé crire le changement de chaque ré sultat. Nous avons aussi appliqué des coefficients de corré lation intra-classe et les erreurs de mesure types pour estimer la fiabilité de test-retest et le changement dé tectable minimal. Ré sultats: Un modè le non liné aire a produit les valeurs suivantes d'adaptation du modè le (R 2 ): P4 ¼ 0,71, ADM extension ¼ 0,51, ADM flexion ¼ 0,99, EFMI ¼ 0,97. Dans le cas de la douleur et de l'ADM, les valeurs maximales ont é té atteintes vers la 12 e semaine suivant la reconstruction et les valeurs EFMI ont continué d'augmenter jusqu'à 26 semaines. Les coefficients de fiabilité de test-retest ont varié de 0,85 à 0,95. Conclusions: L'amé lioration la plus importante s'est produite au cours des huit semaines suivant l'intervention chirurgicale. Le ré tablissement é tait presque complet à 12 semaines en ce qui a trait à la douleur et à l'ADM, mê me si l'é tat fonctionnel des membres infé rieurs a continué de s'amé liorer durant toute la pé riode d'é tude. Les ré sultats de toutes les mesures ont dé montré de la fiabilité , ce qui appuie leur utilisation avec des patients particuliers.Understanding patients' clinical course following anterior cruciate ligament (ACL) reconstruction is of interest to physical therapists working in orthopaedics in general and with athletic injuries specifically. 1 The term clinical course refers to how patients change over the course of treatment with respect to outcomes that are of interest to both patients a...

“…However, more recent guidelines suggest that performance on RTS tests must be at least 90% that of the un-involved extremity. Examples of RTS tests commonly implemented include the 5-jump test, single leg hop for distance, triple hop for distance, single leg cross over hop for distance, single leg 6 meter hop for time, or some combination of these tests [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Objective: Re-injury rates following anterior cruciate ligament reconstruction (ACLR) are elevated compared to rates for initial anterior cruciate ligament (ACL) injury. The purpose of this study was to examine three-dimensional knee mechanics in an individual who had undergone an ACLR and then went on to re-injure that reconstructed ACL. Methods:The primary subject was a female soccer player, 18 months post-ACLR, who then re-injured her ACL 3 months after biomechanical testing and return to sport (RTS) testing. We conducted 3-dimensional biomechanical testing of her knee mechanics and performance on return to sport (RTS) tests prior to her ACL re-injury. In addition, we compared her knee mechanics prior to re-injury to a control group of healthy female soccer athletes to determine if any biomechanical differences existed that may have indicated risk for ACL re-injury. Results:Our findings indicate that altered lower extremity biomechanics, previously associated with increased risk of ACL injury, are present following ACLR and return to sports participation despite a lack of marked bilateral differences in performance on return to sport tests. Conclusion:These findings are consistent with those in the literature suggesting that subjects' post-ACLR may be adopting a strategy that minimizes loading at the knee joint. While it is not known if this biomechanical pattern increases the risk for a re-injury event, it suggests that there are deficits present following ACLR that may not be addressed with rehabilitation and recognized with RTS testing prior to return to sports participation. These findings point to an important gap in the literature with regards to clinical predictors of ACL re-injury.

“…The test protocol, utilized in this study, has been found reliable (ICC = 0.88; SEM = 4.32%) and valid in young to middleaged patients following anterior cruciate ligament reconstruction [18].To ensure that the jumps were maximal, the protocol was modified to allow the non-tested leg to be used for balance upon the last landing. Participants performed three maximal jumps.…”

Independent sample t-test was performed to assess between-group differences. The paired t-test was used to analyze betweenlimb differences in unilateral performance tasks. ResultsThe patients had worse scores than the controls in all HAGOS-subscales (p ≤ 0.001), while no statistically significant differences were observed for any performance measure between groups or between symptomatic and non-symptomatic limbs. ConclusionsDespite significant self-reported functional limitations on the HAGOS, there were no significant differences between groups in performance-based strength or power measures. The results of this study highlight the need to identify performance-based measures, sensitive to functional deficiencies in patients with long-standing hip and groin pain in order to complement the clinical picture obtained by patient-reported outcomes such as the HAGOS.Case-control, Level of evidence III
