- Background This cross-sectional study aimed to examine whether appraisal of knee function, psychological and demographic factors were related to returning to the preinjury sport and recreational activity following anterior cruciate ligament (ACL) reconstruction. Method 164 participants completed a questionnaire battery at 1-7 years after primary ACL reconstruction. The battery included questionnaires evaluating knee self-efficacy, health locus of control, psychological readiness to return to sport and recreational activity, and fear of reinjury; and self-reported knee function in sport-specific tasks, knee-related quality of life and satisfaction with knee function. The primary outcome was returning to the preinjury sport or recreational activity. Results At follow-up, 40% (66/164) had returned to their preinjury activity. Those who returned had more positive psychological responses, reported better knee function in sport and recreational activities, perceived a higher knee-related quality of life and were more satisfied with their current knee function. The main reasons for not returning were not trusting the knee (28%), fear of a new injury (24%) and poor knee function (22%). Psychological readiness to return to sport and recreational activity, measured with the ACL-Return to Sport after Injury scale (was most strongly associated with returning to the preinjury activity). Age, sex and preinjury activity level were not related. Conclusions Less than 50% returned to their preinjury sport or recreational activity after ACL reconstruction. Psychological readiness to return to sport and recreation was the factor most strongly associated with returning to the preinjury activity. Including interventions aimed at improving this in postoperative rehabilitation programmes could be warranted to improve the rate of return to sport and recreational activities.

- Objective: There is no evidence that a knee arthroscopy is more beneficial to middle-aged patients with meniscal symptoms compared to other treatments. This randomised controlled trial aimed to determine whether an arthroscopic intervention combined with a structured exercise programme would provide more benefit than a structured exercise programme alone for middle-aged patients with meniscal symptoms that have undergone physiotherapy. Method: 150 out of 179 eligible patients, aged 45 to 64 (mean: 54 +/- 5), symptom duration more than 3 months and standing X-ray with Ahlback grade 0, were randomised to: (1) a physiotherapy appointment within 2 weeks of inclusion that included instructions for a 3-month exercise programme (non-surgery group); or (2) the same as (1) plus, within 4 weeks of inclusion, knee arthroscopy for resection of any significant meniscal injuries (surgery group). The primary outcome was change in pain at 12 months, assessed with the Knee Injury and Osteoarthritis Outcome Score (KOOSPAIN). Results: In the Intention-To-Treat analysis, pain at 12 months was significantly lower in the surgery than in the non-surgery group. The change in KOOSPAIN was significantly larger in the surgery than in the non-surgery group (between-group difference was 10.6 points of change; 95% CI: 3.4 to 17.7, P = 0.004). The As-Treated analysis results were consistent with the Intention-To-Treat analysis results. Conclusion: Middle-aged patients with meniscal symptoms may benefit from arthroscopic surgery in addition to a structured exercise programme. Patients age or symptom history (i.e., mechanical symptoms or acute onset of symptoms) didnt affect the outcome.

- Psychological factors may be a hindrance for returning to sport after an anterior cruciate ligament (ACL) reconstruction. The ACL-Return to Sport after Injury scale (ACL-RSI) measures athletes emotions, confidence in performance, and risk appraisal in relation to return to sport. The aim of this study was to translate the ACL-RSI scale from English to Swedish and to examine some of the measurement properties of the Swedish version. The ACL-RSI was translated and culturally adapted. A professional expert group and five patients evaluated face validity. One hundred and eighty-two patients completed the translated ACL-RSI, a project-specific questionnaire, the Tampa Scale of Kinesiophobia (TSK), the Knee-Self-Efficacy Scale (K-SES), the Multidimensional Health Locus of Control (MHLC-C), the Knee injury and Osteoarthritis Outcome Score (KOOS), and the Anterior Cruciate Ligament-Quality of Life (ACL-QoL) questionnaires. Fifty-three patients answered the ACL-RSI twice to examine reproducibility. The ACL-RSI showed good face validity, internal consistency (Cronbachs alpha=0.948), low floor and ceiling effects and high construct validity when evaluated against the TSK, K-SES, MHLC-C, KOOS, and ACL-QoL scales. The reproducibility was also high (intra-class correlation=0.893). Therefore, the ACL-RSI can be used to evaluate psychological factors relevant to returning to sport after ACL reconstruction surgery.

- Background: Differences in knee joint stabilization between children and adults and between the sexes are not fully understood. Purpose: To compare the knee laxity and the dynamic tibial translation between (1) children and adults, (2) girls and boys, and (3) women and men. Study Design: Controlled laboratory study.Methods: Sixty-seven children (aged 8-13 years) and 63 adults (aged 18-30 years) without previous knee injuries participated. Sagittal tibial translation was measured during the instrumented Lachman test at 90 N and 134 N (knee laxity) and during gait (dynamic translation). Tibial translation was recorded with an electrogoniometer.Results: Knee laxity was greater in children than in adults (Lachman test at 90 N: 9.1 +/- 2.9 vs 7.3 +/- 2.7, respectively; P less than .001). In contrast, dynamic tibial translation during gait did not differ between children and adults. Girls and boys did not differ in knee laxity or maximum anterior tibial translation during gait, and men and women did not differ in knee laxity. Women had greater dynamic tibial translation during gait than men (7.8 +/- 2.7 vs 5.7 +/- 3.0, respectively; P = .004).Conclusion: Children had greater knee laxity than adults, whereas the dynamic tibial translation did not differ. In adults, knee laxity did not differ between the sexes, but dynamic tibial translation was greater in women. Clinical Relevance: Children and men had less dynamic tibial translation during gait in proportion to their maximum knee laxity. The observed less dynamic tibial translation in children and adult men might be related to their reduced risk of sustaining an anterior cruciate ligament injury.

- Background: It is unclear which rehabilitation exercises involve adequate muscle activationwithout excessive anterior tibial translation after ACL reconstruction.Hypothesis: ACL reconstruction will reduce dynamic tibial translation to the level observedin the uninjured knee. The muscle recruitment pattern will be altered 5 weeks after ACLreconstruction, and some rehabilitation exercises will be more beneficial than others due tovarying amounts of dynamic tibial translation and muscle activation.Study Design: Descriptive Laboratory Study.Methods: Sagittal tibial translation and muscle activation were measured with the Lachmantest (static translation) and 7 rehabilitation exercises (dynamic translation) in 19 patients.Results obtained 5 weeks after ACL reconstruction were compared to those obtained beforethe injury (ACL-deficient knee) and in the uninjured knee.Results: Five weeks after ACL reconstruction the seated knee extension producedsignificantly more anterior tibial translation than the straight leg raise and standing on one leg.The static and dynamic tibial translations measured in ACL reconstructed knees were similarto those measured in uninjured knees. After ACL reconstruction, the patients used a jointstiffening strategy that employed more hamstring activation and reduced the dynamic tibialtranslation.Conclusions: ACL reconstruction reduced dynamic tibial translation compared to thatobserved before treatment. The muscle recruitment pattern in exercises was altered after ACLreconstruction.
