- Anterior cruciate ligament (ACL) injury is a common injury and is often associated with concomitant injuries to the menisci and cartilage and, in the long term, osteoarthritis. Preventive training programs have shown to be highly effective in terms of reducing the risk for ACL injury in sports. ACL reconstruction is indicated when the patient experiences symtoms of instability (»giving way«) despite rehabilitation with a physiotherapist aiming to gain neuromuscular control of the knee. Early ACL reconstruction may be indicated, for example when the patient desires to return to pivoting contact-sports at high level. Modern surgical technique for ACL reconstruction has evolved rapidly and includes »anatomic reconstruction« and individualized treatment, where each patient's unique anatomy, injury and requests on knee function are taken into consideration. In Sweden, more than 90% of all ACL reconstructions performed are included into the Swedish National ACL Register.

- Sagittal translation of the tibia was examined in a static test with 90 N force at 20°of knee flexion and dynamically during knee extension in a Biodex machine using increasing quadriceps torque in six healthy volunteers. The translation increased in a non-linear fashion with increasing torque. Similar relative increases in quadriceps torque caused similar relative increases in translation in the different individuals. The dynamic translation at the individual maximum quadriceps torque was equal to the static 90-N translation. There was a negative correlation between the maximum quadriceps torque and the static 90-N translation. The results indicate that the quadriceps torque is related to the amount of translation in the knee joint possibly by some feed back mechanism from the ligaments preventing abnormal translation. The findings also imply that a limitation of quadriceps torque around 80% of maximum would limit the strain in an injured ligament to a level not higher than what is caused by normal laxity measurements.

- BACKGROUND: After a serious knee injury, up to half of athletes do not return to competitive sport, despite recovering sufficient physical function. Athletes often desire psychological support for the return to sport, but rehabilitation clinicians feel ill-equipped to deliver adequate support.OBJECTIVE: We aimed to design and develop an internet-delivered psychological support program for athletes recovering from knee ligament surgery.METHODS: Our work for developing and designing the Back in the Game intervention was guided by a blend of theory-, evidence-, and target population-based strategies for developing complex interventions. We systematically searched for qualitative evidence related to athletes' experiences with, perspectives on, and needs for recovery and return to sport after anterior cruciate ligament (ACL) injury. Two reviewers coded and synthesized the results via thematic meta-synthesis. We systematically searched for randomized controlled trials reporting on psychological support interventions for improving ACL rehabilitation outcomes in athletes. One reviewer extracted the data, including effect estimates; a second reviewer checked the data for accuracy. The results were synthesized descriptively. We conducted feasibility testing in two phases-(1) technical assessment and (2) feasibility and usability testing. For phase 1, we recruited clinicians and people with lived experience of ACL injury. For phase 2, we recruited patients aged between 15 and 30 years who were within 8 weeks of ACL reconstruction surgery. Participants completed a 10-week version of the intervention and semistructured interviews for evaluating acceptability, demand, practicality, and integration. This project was approved by the Swedish Ethical Review Authority (approval number: 2018/45-31).RESULTS: The following three analytic themes emerged from the meta-synthesis (studies: n=16; participants: n=164): (1) tools or strategies for supporting rehabilitation progress, (2) barriers and facilitators for the physical readiness to return to sport, and (3) barriers and facilitators for the psychological readiness to return to sport. Coping strategies, relaxation, and goal setting may have a positive effect on rehabilitation outcomes after ACL reconstruction (randomized controlled trials: n=7; participants: n=430). There were no trials of psychological support interventions for improving the return to sport. Eleven people completed phase 1 of feasibility testing (technical assessment) and identified 4 types of software errors, which we fixed. Six participants completed the feasibility and usability testing phase. Their feedback suggested that the intervention was easy to access and addressed the needs of athletes who want to return to sport after ACL reconstruction. We refined the intervention to include more multimedia content and support access to and the use of the intervention features.CONCLUSIONS: The Back in the Game intervention is a 24-week, internet-delivered, self-guided program that comprises 7 modules that complement usual rehabilitation, changes focus as rehabilitation progresses, is easy to access and use, and includes different psychological support strategies.

Tidskriftsartikel (refereegranskat)abstract
- Background: Sustaining injury is a common consequence of playing sport. At least one in every three recreational athletes with anterior cruciate ligament (ACL) reconstruction do not return to their preinjury sport following treatment. Psychological factors including confidence and fear of new injury exert large effects on returning to sport. The primary aim of this trial is to test whether a custom smartphone application delivering cognitive-behavioural therapy is effective for improving the number of people who return to their preinjury sport and level following ACL reconstruction. Methods: Participants scheduled for primary ACL reconstruction are recruited prior to surgery from one of six trial sites in Sweden. We aim to recruit 222 participants (111 in each group) for the BANG trial. Participants are randomly allocated to receive either usual rehabilitation care alone or usual rehabilitation care plus the Back in the Game smartphone application intervention. Back in the Game is a 24-week Internet-delivered programme, based on cognitive-behavioural therapy. The primary outcome is return to the preinjury sport and level at 12 months follow-up. The secondary outcomes assess physical activity participation, new knee injuries, psychological factors, quality of life and physical function. Physical activity participation and new injuries are self-reported every two weeks for 12 months, then every 4 weeks to 24 months follow-up. Psychological readiness to return to sport, knee self-efficacy, motivation to participate in leisure time physical activity, knee-related quality of life, and self-reported knee function are also assessed at 3, 6, 9, 12 and 24 months after surgery. A clinical assessment of strength, knee range of motion, effusion and hopping performance is completed by a blinded assessor at 12 months to assess physical function. Discussion: This protocol outlines how we plan to assess the efficacy of a custom smartphone application, delivering cognitive-behavioural therapy to address fear, confidence and recovery expectations, for improving return to sport following serious sports-related musculoskeletal injury. The BANG trial employs a pragmatic design to best reflect the reality of, and inform, clinical practice.

- The aim of our study was to cross-sectionally compare patient-reported knee function outcomes between people who chose non-surgical treatment for ACL injury and those who chose ACL reconstruction. We extracted Knee Injury and Osteoarthritis Outcome Score (KOOS) and EuroQoL-5D data entered into the Swedish National ACL Registry by patients with a non-surgically treated ACL injury within 180 days of injury (n = 306), 1 (n = 350), 2 (n = 358), and 5 years (n = 114) after injury. These data were compared cross-sectionally to data collected pre-operatively (n = 306) and at 1 (n = 350), 2 (n = 358), and 5 years (n = 114) post-operatively from age- and gender-matched groups of patients with primary ACL reconstruction. At the 1 and 2 year comparisons, patients who chose surgical treatment reported superior quality of life and function in sports (1 year mean difference 12.4 and 13.2 points, respectively; 2 year mean difference 4.5 and 6.9 points, respectively) compared to those who chose non-surgical treatment. Patients who chose ACL reconstruction reported superior outcomes for knee symptoms and function, and in knee-specific and health-related quality of life, compared to patients who chose non-surgical treatment.

- Impairment-based evaluation has, until recently, been the mainstay of orthopaedic research in anterior cruciate ligament (ACL) reconstruction. However, participation-based outcomes, in particular returning to sport, have lately garnered increased research attention. This is important because returning to sport is typically a main concern of injured athletes. Recent metaanalyses have demonstrated that the return to sport rate after ACL reconstruction is disappointingly low, and that a range of contextual factors including age, sex, sport participation level, and psychological factors may affect the return to sport rate. Moderate to large effect sizes have been demonstrated for greater psychological readiness to return to sport, and lower fear of reinjury favoring returning to the preinjury level sport after ACL reconstruction. Understanding the relationship between psychological factors and returning to sport is essential in light of the fact that most athletes recover good physical function after surgery, and many athletes with good knee function do not return to sport. Psychological factors are potentially modifiable with appropriate intervention, yet these factors are not systematically addressed in routine postoperative rehabilitation. This review summarizes the recent evidence for the relationship between psychological factors and ACL injury, including recovery from injury and returning to sport.

- Purpose: To assess whether patient-reported outcomes (psychological factors, appraisals of knee function, and physical activity participation) were associated with satisfaction with knee function after anterior cruciate ligament (ACL) reconstruction. Methods: Participants who were aged 18 to 45 years and a minimum 12 months post primary ACL reconstruction completed a questionnaire battery evaluating knee self-efficacy, knee-related quality of life, self-reported function, and physical activity participation. Participants' responses to the question "If you were to spend the rest of your life with your knee just the way it has been in the last week, would you feel.... (7-point ordinal scale; 1 = happy, 7 = unhappy)" were categorized as satisfied, mostly satisfied, or dissatisfied and used as the primary outcome. Ordinal regression was used to examine associations between independent variables and the primary outcome. Results: A total of 177 participants were included at an average of 3 years after primary ACL reconstruction. At follow-up, 44% reported they would be satisfied, 28% mostly satisfied, and 28% dissatisfied with the outcome of ACL reconstruction. There were significant differences in psychological responses and appraisal of knee function between the 3 groups (P = .001), and significantly more people in the satisfied group had returned to their preinjury activity (58%) than in the mostly satisfied (28%) and dissatisfied (26%) groups (P = .001). Multivariable analysis demonstrated that the odds of being satisfied increased by a factor of 3 with higher self-efficacy, greater knee-related quality of life, and returning to the preinjury activity. Conclusions: People who had returned to their preinjury physical activity and who reported higher knee-related self-efficacy and quality of life were more likely to be satisfied with the outcome of ACL reconstruction.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Forskningsöversikt (refereegranskat)abstract
- One of the main indications for anterior cruciate ligament reconstruction is the athlete’s desire to return to his or her preinjury level of sports. Postoperative rehabilitation has a strong focus on recovery of the physical capabilities necessary to manage a return to sports. On average, athletes achieve good physical function after surgery, based on standard impairment-based and activity-based measures. Yet the return to sports rate is disappointingly low; only two in every three return to their preinjury level sport and only half of the athletes return to competitive sports after surgery. There are a range of factors, many of them nonmodifiable (e.g. age, sex, and preinjury level of competition), that affect returning to a specific sport. However, recent research has identified psychological factors as key influences on returning to sports after anterior cruciate ligament reconstruction. This is particularly important for clinicians given that these factors may be modifiable with appropriate intervention. However, they are not systematically discussed during standard postoperative rehabilitation. In this review, we examine the evidence for the effect of psychological factors on return to sport outcomes after anterior cruciate ligament reconstruction and provide a rationale for the inclusion of interventions that specifically and systematically affect these factors during postoperative rehabilitation.
