An examination of changes in psychological status across four phases of injury recovery and return to sport: A prospective weekly study of competitive athletes from acute care to return to sport.

While ample research has shown that sport injuries are associated with poor psychological status, scant attention has been given to changes in injured athletes' psychological status over the full course of recovery and return to sport. The aim of the present study was to prospectively investigate potential changes in injured athletes' psychological status across four phases of recovery and return to sport. A total of 38 severely injured adult competitive athletes (58% female; mean age 24.1 ± 7.18 years) participated in this prospective weekly investigation (n = 319 observations). Athletes' were asked to indicate their current phase of recovery or return to sport (acute care, rehabilitation, adapted training, or full return to sport) after which they responded to visual analog scales assessing post-injury psychological status, including: perceived pain (frequency and intensity), emotions (positive and negative), anxiety (cognitive and physiological), motivation, self-efficacy, and satisfaction. During the acute care phase, participants showed higher scores of perceived pain, and physiological anxiety compared to the other phases. During the adapted training phase, amotivation was higher than in the acute care phase, and self-efficacy was lower than in other phases. At full return to sport, athletes showed less perceived pain, cognitive anxiety, and more satisfaction than during other phases. The present study provides a deeper prospective understanding of changes in athlete's psychological status over the course of injury recovery and return to sport and highlight the importance of monitoring psychological status.

Psychosocial experiences of competitive rugby players on the "long, long journey" to recovery following ACL ruptures and reconstruction.

Anterior Cruciate Ligament (ACL) injuries are serious and potentially career-ending. Reconstruction surgery and extended rehabilitation typically follow, but some athletes never attain the same level of sport performance. The psychosocial experiences of athletes who sustain ACL injuries and their cognitive appraisal, emotional and behavioral responses to the injury, and reconstruction require further attention during the different recovery phases. The aim is to explore these psychosocial experiences, social support needs and sources thereof of competitive athletes who sustained unilateral ACL ruptures and underwent reconstruction surgery. Semi-structured interviews with six competitive rugby players (M age: 22.3 ± 2.92 years), elicited information at seven time-points. We analyzed the qualitative information through thematic analysis. Five common themes emerged: (1) cognitive appraisal, (2) emotional responses (negative and positive affective responses), (3) behavioral responses, (4) social support needs and sources thereof, and (5) adversity-induced identity expansion (athletic and person-centered identities). In-vivo quotes gave a rich description of the athletes' experiences throughout the "long, long journey" to return-to-sport. These findings may sensitize and assist sports healthcare professionals, coaches, teammates, family, and friends to explore various psychosocial experiences throughout the injury and recovery period. Phase-appropriate psychosocial support or referral to sport psychology services is recommended to enhance the recovery process, improve long-term physical and mental health, and subsequent performance.

Reinjury Anxiety and Return to Sport After Anterior Cruciate Ligament Reconstruction: A Cluster Analysis and Prospective Study Among 162 Athletes.

BACKGROUND: Recent studies have investigated the effect of psychological factors on return to sport (RTS), but none has tested the existence of psychological profiles linked to reinjury anxiety and its links with RTS and reinjury. PURPOSE: To assess the effect of different psychological profiles on RTS and reinjury. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: The study screened patients who were involved in all types of sports for anterior cruciate ligament (ACL) reconstruction (hamstring and patellar tendon autografts). All participants were included during the RTS phase (90-180 days after ACL reconstruction). Reinjury anxiety, fear of reinjury, kinesiophobia, perceived stress, anxiety, depression, knee confidence, self-esteem, optimism, coping, and pain were measured. Hierarchical cluster analysis (Ward method) and analysis of variance were performed. In the second year after surgery, patients were recontacted by telephone to follow-up. RTS and reinjury were compared by profile type. RESULTS: A total of 162 athletes were initially included, of whom 123 responded regarding RTS and reinjury. Cluster analysis showed a 4-cluster solution (χ2[21] = 428.59; λ = .064; P < .001). Profile 1 (27.8%) was characterized by moderate reinjury anxiety and no depression. Profile 2 (22.8%) was characterized by moderate reinjury anxiety and minor anxious-depressive reaction. Profile 3 (30.9%) was characterized by no reinjury anxiety, no depression, and high confidence. Profile 4 (18.5%) was characterized by high anxiety, high depression, and low confidence. Profile 4 had the lowest self-esteem and optimism scores compared with profile 3 (P < .001). In addition, a higher percentage of men was found in profile 3 as opposed to profile 4 (χ2[3] = 11.35; P < .01). Profile 4 had the highest rate of non-RTS with 54.2% (profile 1: 14.3%, P = .001; profile 2: 25.0%, P = .031; profile 3: 22.2%, P = .011). Finally, patients with profile 3 had a higher risk of reinjury (13.9%) than those with profile 4 (0%) (P = .047), who had an extremely conservative RTS. CONCLUSION: The different profiles will affect RTS, but also the risk of reinjury exclusively for profiles 3 and 4. Rehabilitation management will probably require all stakeholders to understand psychological profiles of athletes to develop an on-demand rehabilitation plan.

Postoperative Return to Play and the Role of Imaging.

Return to play (RTP) following surgery is a complex subject at the interface of social and internal pressures experienced by the athlete, psychological readiness, and intrinsic healing of the surgically repaired structures. Although functional testing, time from surgery, clinical examination, and scoring metrics can help clarify an athlete's readiness to return to sport, imaging can allow for a more direct assessment of the structures in question. Because imaging is often included in the diagnostic work-up of pain following surgery, the radiologist must be familiar with the expected postsurgical imaging appearance, as well as the associated complications. We briefly review such findings following anterior cruciate ligament reconstruction, Achilles tendon repair, syndesmotic fixation, and ulnar collateral ligament reconstruction in the context of the athlete, highlighting issues related to RTP.

The Influence of Psychosocial Factors on Patients Undergoing Anterior Cruciate Ligament Reconstruction.

CONTEXT: Anterior cruciate ligament (ACL) injuries greatly impact patients in terms of future performance, reduced physical activity and athletic participation, and overall economic burden. Decades of research have investigated how to improve ACL reconstruction (ACLR) outcomes. Recently, there has been growing interest to understand the effects of psychosocial factors on patient outcomes. STUDY DESIGN: Clinical review. EVIDENCE ACQUISITION: A search of the PubMed database was performed in March 2023. Articles were reviewed by at least 2 authors to determine relevance. We highlighted publications of the past 5 years while incorporating previous pertinent studies. LEVEL OF EVIDENCE: Level 5. RESULTS: There is no standardization of psychosocial factors regarding ACLR. As such, there is a lack of consensus regarding which psychosocial measures to use and when. There is a need for clarification of the complex relationship between psychosocial factors and physical function. Despite this, psychosocial factors have the potential to help predict patients who are more likely to return to sport: (1) desire/motivation to return; (2) lower levels of kinesiophobia; (3) higher levels of self-efficacy, confidence, and subjective knee function; (4) risk acceptance; and (5) social support. However, there are no standardized interventions to improve psychosocial factors after ACLR. CONCLUSION: Psychosocial factors affect outcomes after ACLR. However, the interplay between psychosocial factors and physical function is complex. There is emerging evidence that testing and interventions may improve ACLR outcomes. There is a lack of standardized interventions to determine or improve psychosocial factors after ACLR. Further research is needed to identify psychosocial factors and to develop standardized interventions for clinicians to implement to improve clinical outcomes.

The Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI) is a valid and reliable measure to assess psychological readiness before returning to sport following peroneal tendon pathology surgery.

PURPOSE: The objective of this study was to validate a scale that could help surgeons evaluate patients' psychological readiness to return to sport (RTS) after peroneal tendon pathology surgery. METHODS: The Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI) scale, which had previously been validated in ankle ligament reconstruction patients, was adapted to evaluate the psychological preparedness for RTS in athletic patients who underwent peroneal tendinopathy surgery. The Foot and Ankle Outcome Score (FAOS) and Foot Ankle Ability Measurement (FAAM) scores were employed as patient-related outcome measurement (PROM) instruments. RESULTS: This study included 57 patients. There was a strong correlation between ALR-RSI and both FAOS and FAAM (r = -0.68 and 0.74, respectively). ALR-RSI was considerably higher in patients who returned to sports than in those who did not. The mean score was 72.9 ± 19.0 in patients who returned to the same preinjury level, 48.5 ± 24.0 in those who returned to a lower level and 53.6 ± 31.1 in patients who changed their athletic activity (p < 0.0001). Furthermore, ALR-RSI showed at least a similar discrimination ability when compared to FAOS and FAAM. The test-retest intraclass correlation coefficient was 0.95. The Cronbach's α statistic used to measure the internal consistency was high (0.95). A Youden index of 0.65 was observed for a cut-off score of 68 points. CONCLUSION: ALR-RSI is a valid instrument for assessing psychological readiness to RTS in an athletic population following peroneal tendon surgery. When compared to the most commonly used PROMs, it was strongly correlated and demonstrated at least similar discrimination capacity. This could assist surgeons in identifying athletes who will have poor postoperative results and advising them on their capability to RTS. LEVEL OF EVIDENCE: Level III.

The Influence of Strength and Sport Exposure on Psychological Readiness After ACL Reconstruction.

BACKGROUND: Among young athletes returning to sport after anterior cruciate ligament reconstruction (ACLR), the extent to which psychological readiness is influenced by factors beyond the psychological domain is largely unknown. HYPOTHESIS: Young athletes with recent sport exposure and higher quadriceps strength will demonstrate higher psychological readiness within 8 weeks of medical clearance to return to sport (RTS) after ACLR. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 38 young athletes after primary ACLR completed testing within 8 weeks of medical clearance to RTS. All participants completed isometric knee extension strength testing, in addition to the ACL Return to Sport after Injury (ACL-RSI) questionnaire. Athletes who participated in sport between time of medical clearance to RTS and date of study enrollment were categorized as SPORT-YES. Those who had not yet participated in sports were categorized as SPORT-NO. Multiple linear regression analyses were used to determine differences in ACL-RSI scores based on quadriceps strength and sport exposure status, while adjusting for age and sex. RESULTS: Of the 38 participants, 20 (52.6%) were categorized as SPORT-YES. The regression model estimating overall ACL-RSI score (P < 0.01, adjusted R2 = 0.389) included significant independent contributions from age, sex, and sport exposure variables (age: P = 0.01, ß [95% CI] = -2.01 [-3.54, -0.48]; sex (male): P = 0.02, ß [95% CI] = 12.50 [2.36, 22.64]; strength: P = 0.51, ß [95% CI] = -2.47 [-10.07,5.13]; sport exposure: P < 0.01, ß [95% CI] = 12.89 [3.58, 22.19]). CONCLUSION: In partial accordance with our hypothesis, recent sport exposure was significantly associated with higher ACL-RSI scores among young athletes in the weeks after medical clearance to RTS after ACLR, while quadriceps strength was not. CLINICAL RELEVANCE: Future prospective work is needed to determine the existence and direction of causal relationships between exposure to sport environment and psychological readiness among young athletes after ACLR.

Knee Confidence, Fear of Movement, and Psychological Readiness for Sport in Individuals With Knee Conditions: A Systematic Review and Meta-analysis.

OBJECTIVES: To (1) compare activity-related psychological factors between individuals with and without knee conditions, and (2) assess associations between these factors and objective measures of function in individuals with knee conditions. DESIGN: A priori registered systematic review with meta-analysis. LITERATURE SEARCH: MEDLINE-Ovid, Embase-Ovid, Scopus-Elsevier, CINAHL-EBSCO, SPORTDiscus-EBSCO, and Cochrane Library were searched to May 27, 2022. STUDY SELECTION CRITERIA: We included peer-reviewed primary data studies (observational and experimental) of human participants with and without knee conditions reporting knee confidence, fear of movement/avoidance beliefs, and/or psychological readiness to return to sport (RTS) or reporting correlations between these factors and objective measures of function in knee conditions. DATA SYNTHESIS: Where possible, data were pooled by knee conditions, otherwise performed narrative syntheses. The Downs and Black checklist assessed the methodological quality of the included studies. RESULTS: Forty studies (3546 participants with knee conditions; 616 participants without knee conditions) were included. There was very low-certainty evidence of higher fear of movement in individuals with knee osteoarthritis (standardized mean difference [SMD], 0.46; 95% confidence interval [CI]: 0.41, 0.52), but not in individuals with patellofemoral pain (SMD, 0.66; 95% CI: -7.98, 9.29) when compared with those without knee conditions. There was very low-certainty evidence of no differences in psychological readiness to RTS after anterior cruciate ligament reconstruction (SMD, -1.14; 95% CI: -2.97, 0.70) compared to no knee condition, and negligible to weak positive correlations between psychological readiness to RTS and objective measures of function. CONCLUSION: There was very low-certainty evidence of higher fear of movement in individuals with knee osteoarthritis compared to those without, and very low-certainty evidence of no correlations between these factors and objective measures of function following anterior cruciate ligament reconstruction.

Female Athletes With Better Psychological Readiness Are at Higher Risk for Second ACL Injury After Primary ACL Reconstruction.

BACKGROUND: Approximately 1 in 4 athletes returning to sports will sustain a second anterior cruciate ligament (ACL) injury. Psychological factors related to kinesiophobia, confidence, and psychological readiness are associated with second ACL injury; however, the evidence is conflicting. HYPOTHESIS: Athletes who sustain a second ACL injury (ie, graft rupture or contralateral ACL rupture) within 2 years of ACL reconstruction (ACLR) would have greater kinesiophobia, less confidence, and lower psychological readiness prior to return to sport (RTS) compared with athletes who do not sustain a second ACL injury. STUDY DESIGN: Secondary analysis of a prospective randomized trial. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 39 female Level I/II athletes completed the following measures after postoperative rehabilitation and a 10-session RTS and second ACL injury prevention program: ACL Return to Sport after Injury (ACL-RSI) scale, the 11-item Tampa Scale of Kinesiophobia (TSK-11), and question 3 on the Knee injury and Osteoarthritis Outcome Score (KOOS) quality of life (QoL) subscale. Athletes were dichotomized based on whether they sustained a second ACL injury within 2 years of ACLR or not. Independent t tests determined group differences in TSK-11, KOOS-QoL, ACL-RSI, and the 3 individual components of the ACL-RSI (ie, emotions, confidence, risk appraisal). RESULTS: Nine athletes sustained a second ACL injury (4 graft ruptures and 5 contralateral ACL ruptures). The group that sustained a second ACL injury had higher scores on the ACL-RSI (P = 0.03), higher on the risk appraisal questions of the ACL-RSI (P < 0.01), and met RTS criteria sooner than athletes who did not (P = 0.04). All second ACL injuries occurred in athletes who underwent primary ACLR with hamstring tendon autografts. CONCLUSION: Athletes who sustained a second ACL within 2 years of ACLR had a more positive psychological outlook, higher scores on the specific questions related to the risk appraisal construct of the ACL-RSI, and met RTS criteria sooner than athletes who did not sustain a second ACL injury. CLINICAL RELEVANCE: Counseling athletes about delaying RTS to reduce the risk of second ACL injury may be especially important in athletes who display high psychological readiness and meet RTS criteria sooner.

Differences in Short-Term Sport-Specific Functional Recovery After Primary ACL Reconstruction in the Adolescent Athlete.

BACKGROUND: Although anterior cruciate ligament (ACL) injury rates have been studied extensively, it is unclear whether levels of functional and psychological readiness for return-to-sport after primary ACL reconstruction (ACLR) differ based on an athlete's primary sport. HYPOTHESIS: Youth athletes in different primary sports will demonstrate differences in short-term functional recovery, as well as patient-reported psychological and functional recovery after primary ACLR. STUDY DESIGN: Retrospective cohort study of consecutive patients treated for ACL injury in pediatric sports medicine clinics. LEVEL OF EVIDENCE: Level 3. METHODS: Patients included underwent primary ACLR between December 1, 2015 and December 31, 2019 and reported sports participation at the time of injury. Demographic data, sports participation, surgical data, functional testing scores (Y-Balance Test [YBT]), functional and psychological patient-reported outcome measures (PROMs), and timing of return-to-play clearance were reviewed. YBT scores were the primary metric for clearance. Four groups were studied: soccer, football, basketball, and other. RESULTS: A total of 220 male and 223 female athletes were included; 65.28% of soccer players were female and 100% of football players were male (P < 0.01). At initial postoperative YBT testing (6-9 months), soccer players had higher operative (P < 0.01) and nonoperative (P < 0.01) leg composite scores when compared with basketball players. No significant differences were found between sports in functional or psychological PROMs at presurgical baseline or 6 months postoperatively. When compared with football, soccer players completed functional clearance in a shorter time from surgery (P = 0.02). Multivariate analysis showed level of competition as a significant independent variable for clearance in female athletes. CONCLUSION: After primary ACLR, athletes, especially female athletes, demonstrated short-term sport-specific differences in YBT scores. Soccer players attained clearance sooner than football players. Level of competition influenced YBT composite scores in all athletes and time to clearance in female athletes. CLINICAL RELEVANCE: Sport-specific differences in reinjury should be investigated to determine whether changes in return-to-play evaluation should be implemented.

Short-term fear of movement improves less after anterior cruciate ligament reconstruction with concomitant meniscus repair.

BACKGROUND: Psychological response is important in return-to-sport decisions for athletes recovering from anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to compare psychological response after ACLR with a concomitant meniscus repair compared to isolated ACLR. METHODS: Thirty-five individuals completed the Tampa Scale of Kinesiophobia (TSK) and Anterior Cruciate Ligament Return-to-Sport after Injury (ACL-RSI) scale before ACLR and 2, 4, and 6 months after ACLR. Participants were dichotomized based on presence of concomitant meniscus repair (Yes/No). Separate group X time repeated measures analyses of variance were conducted for both scales. RESULTS: Participants were 65.7% female, 19.1 ± 4.7 years old with BMI of 24.9 ± 4.4 kg/m2. Sixteen individuals had an isolated ACLR with 19 individuals having an ACLR with concomitant meniscus repair. For the TSK, there was a group × time interaction effect(p = 0.028), with improvement in TSK scores for the isolated ACLR group (ACLR:2 months = 24.8 ± 3.7; 4 months = 22.0 ± 5.7; 6 months: 19.9 ± 5.9; Meniscus Repair:2 months = 25.5 ± 4.7; 4 months = 24.1 ± 5.0; 6 months: 23.8 ± 4.7). Six months after ACLR, TSK scores were worse in the meniscus repair group(p = 0.036). For the ACL-RSI, there was no interaction(p = 0.07). CONCLUSION: Concomitant meniscus repair with ACLR results in less post-operative improvement in kinesiophobia through 6 months after ACLR compared to isolated ACLR.

Validation of the Ankle Ligament Reconstruction-Return to Sports after Injury (ALR-RSI) Score as a Tool to Assess Psychological Readiness to Return to Sport in an Active Population After Ankle Fracture Surgery: A Cross-sectional Study.

Ankle injuries account for 15% to 25% of all sports injuries resulting in significant pain and loss of function. The purpose of this cross-sectional study was to validate a scale to help surgeons quantify the psychological readiness to Return To Sport (RTS) in patients undergoing ankle fracture surgery. ALR-RSI was used to assess the psychological readiness for RTS in athletic patients who underwent ankle fracture fixation between January 2020 and January 2021. Participants filled out ALR-RSI and 2 Patient-Related Outcome Measurement (PROM) tools: Olerud-Molander Ankle Score (OMAS) and Self-Reported Foot and Ankle Score (SEFAS). A total of 93 patients were included. There was a strong correlation between ALR-RSI and both OMAS and SEFAS, with Pearson coefficients of r = 0.58 and 0.53, respectively. ALR-RSI was significantly higher in the RTS group than in those who no longer practiced their main preinjury sport. Moreover, the discriminant validity of ALR-RSI (AUC = 0.81) was better than that of the SEFAS and OMAS (AUC = 0.64 and 0.65, respectively, p = .001). The intra-class correlation coefficient ρ of 0.94 showed excellent reproducibility. At an optimal cutoff value of 76.7, ALR-RSI had a sensitivity of 81% and a specificity of 75% with a Youden index of 0.56. In conclusion, ALR-RSI was a valid and reproducible tool to evaluate the psychological readiness for RTS in an active population after an ankle fracture. This score could help surgeons identify athletes who may have unfavorable postoperative outcomes and provide support on the ability to RTS.

Current Rehabilitation Practices and Return to Sports Criteria After Anterior Cruciate Ligament Reconstruction: A Survey of Physical Therapists in Saudi Arabia.

CONTEXT: With the high prevalence of anterior cruciate ligament rupture among young and active individuals, rehabilitation after the injury and surgery should meet the current evidence-based recommendations to restore knee function and reduce the risk of further injury. This study aimed to investigate the current rehabilitation practices and return to sports (RTS) criteria after anterior cruciate ligament reconstruction (ACLR) among physical therapists in Saudi Arabia. DESIGN: Online cross-sectional survey-based study. METHODS: A total of 177 physical therapists in Saudi Arabia participated in this survey. The survey included questions about the preferred postoperative timing and frequency of rehabilitation, current views on the importance of preoperative and postoperative rehabilitation to the overall outcomes, the timeframe of RTS, and the decision-making process to RTS. RESULTS: Most therapists (96.6%) believed preoperative rehabilitation was essential/important to postoperative outcomes. Two-thirds encouraged patients to start rehabilitation program within 1 to 4 days immediately post-ACLR. RTS was permitted 6 to 9 months post-ACLR by 60% of therapists if satisfied with patient progress and capacity. Factors considered before RTS included knee strength (72.9%), functional capacity (86.4%), lower limb and trunk mechanics (62.7%), and psychological readiness (42.2%). Knee strength was assessed by manual muscle testing (39%), handheld dynamometry (15.3%), and isokinetic dynamometer (13.6%). While 60% of the therapists used single-limbed hop for distance for evaluating functional capacity, only 27.1% used a hop test battery. CONCLUSIONS: The surveyed physical therapists in Saudi Arabia demonstrated variations in the current rehabilitation practices and RTS criteria post-ACLR. Over half of the surveyed therapists considered preoperative rehabilitation essential to postoperative outcomes. However, the therapists should update their perspective with current evidence-based practice regarding the RTS timeframe, psychological readiness assessment for RTS, and knee strength evaluation using objective measurements.

Psychological Readiness, Injury-Related Fear, and Persistent Knee Symptoms After Anterior Cruciate Ligament Reconstruction.

CONTEXT: Poor psychological responses after anterior cruciate ligament reconstruction (ACLR) have been associated with a failure to return to sport and increased secondary injury risk. However, we do not know whether poor psychological responses after ACLR influence patient-reported knee function and knee symptoms. OBJECTIVE: To examine the association between psychological factors (ie, psychological readiness and injury-related fear) and the presence of persistent knee symptoms in individuals 6 to 12 months after ACLR. DESIGN: Cross-sectional study. SETTING: Research laboratory. PATIENTS OR OTHER PARTICIPANTS: In total, 101 participants, aged 13 to 25 years old, between 6 and 12 months after primary unilateral ACLR were enrolled in the study. MAIN OUTCOME MEASURE(S): Persistent knee symptoms were identified using an established criterion based on the subscales of the Knee injury and Osteoarthritis Outcome Score. Participants also completed the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) and the Tampa Scale of Kinesiophobia-11 (TSK-11) to assess psychological readiness and injury-related fear, respectively. Higher ACL-RSI scores indicate higher psychological readiness, and higher TSK-11 scores indicate higher injury-related fear. RESULTS: Twenty-nine participants (29%) met the criteria for persistent knee symptoms. For every 1 SD lower in the ACL-RSI score, participants had 2.1 times greater odds of persistent knee symptoms after ACLR (95% CI = 1.3, 3.6). For every 1 SD higher in the TSK-11 score, participants had 1.9 times greater odds of persistent knee symptoms after ACLR (95% CI = 1.1, 3.3). Both the ACL-RSI and TSK-11 were considered good at classifying persistent knee symptoms, as the areas under the curve were 0.78 and 0.73, respectively. CONCLUSIONS: Individuals with a lower level of psychological readiness and more injury-related fear after ACLR had greater odds of persistent knee symptoms. Overall, these results highlight the potential clinical benefit of a comprehensive, biopsychosocial approach to managing health and wellness for individuals after ACLR.

Substantial influence of psychological factors on return to sports after anterior shoulder instability surgery: a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis aimed to (1) determine the proportion of patients who underwent anterior shoulder instability surgery and did not return to sports for psychological reasons and (2) estimate differences in psychological readiness scores between patients who did and did not return to sports. METHODS: The EBSCOhost/SPORTDiscus, PubMed/Medline, Scopus, EMBASE and Cochrane Library databases were searched for relevant studies. The data synthesis included the proportion of patients who did not return to sports for psychological reasons and the mean differences in the psychological readiness of athletes who returned and those who did not return to sports. Non-binomial data were analysed using the inverse-variance approach and expressed as the mean difference with 95% confidence intervals. RESULTS: The search yielded 700 records, of which 13 (1093 patients) were included. Fourteen psychological factors were identified as potential causes for not returning to sports. The rates of return to sports at any level or to the preinjury level were 79.3% and 61.9%, respectively. A total of 55.9% of the patients cited psychological factors as the primary reason for not returning to sports. The pooled estimate showed that patients who returned to sports had a significantly higher Shoulder Instability-Return to Sport After Injury score (P < 0.00001) than those who did not, with a mean difference of 30.24 (95% CI 24.95-35.53; I2 = 0%; n.s.). CONCLUSIONS: Psychological factors have a substantial impact on the rate of return to sports after anterior shoulder instability surgery. Patients who returned to sports had significantly higher psychological readiness than those who did not return to sports. Based on these results, healthcare professionals should include psychological and functional measurements when assessing athletes' readiness to return to sports. LEVEL OF EVIDENCE: Level IV.

Greater self-efficacy, psychological readiness and return to sport amongst paediatric patients compared with adolescents and young adults, 8 and 12 months after ACL reconstruction.

PURPOSE: The purpose of this study was to evaluate differences in rehabilitation-specific outcomes between paediatric patients, adolescents and young adults within the first 2 years after anterior cruciate ligament (ACL) reconstruction. A further aim was to determine whether patient age was associated with an increased risk of not achieving symmetrical muscle function within the first 2 years after ACL reconstruction. METHODS: The patient data in the present study were extracted from the rehabilitation outcome registry, Project ACL. Patients aged 11-25 years registered for primary ACL reconstruction with a hamstring tendon autograft between April 1, 2013 and November 23, 2020 were included. A total of 691 patients met the inclusion criteria and were included in the study; 41 paediatric patients (females 11-13, males 11-15 years), 347 adolescents (females 14-19, males 16-19 years) and 303 young adults (females 20-25, males 20-25 years). RESULTS: The comparison between groups revealed that 70% of paediatric patients, 39% of adolescents and 35% of young adults had returned to knee-strenuous sport at 8 months and that 90% of paediatric patients, 71% of adolescents and 62% of young adults had returned to sport at 12 months. Paediatric patients also reported higher scores compared with both the other patient groups on the Knee Self-Efficacy Scale (K-SES) and the Anterior Cruciate Ligament Return to Sport after Injury scale (ACL-RSI) at 8 and 12 months. CONCLUSIONS: A larger proportion of paediatric patients had returned to sport compared with adolescents and young adults 8 and 12 months after ACL reconstruction. Paediatric patients also reported higher self-efficacy and greater psychological readiness to return to sport at 8 and 12 months than the other two groups. No differences in terms of muscle function tests when comparing paediatric patients, adolescents and young adults were found. LEVEL OF EVIDENCE: II.

Factors Associated With Sports Function and Psychological Readiness to Return to Sports at 12 Months After Anterior Cruciate Ligament Reconstruction: A Cross-sectional Study.

BACKGROUND: Sports function and psychological readiness to return to sports (RTS) are important outcomes when evaluating rehabilitation after anterior cruciate ligament reconstruction (ACLR). It is, however, unclear which specific factors contribute most to these outcomes. PURPOSE: To determine associations between demographic characteristics, objective measurements of physical function, patient-reported outcome measure scores, sports-related function assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS) Sport and Recreation subscale, and psychological readiness to RTS assessed with the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale at 1 year after ACLR. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: At a mean of 12.5 ± 2.0 months after ACLR, 143 participants (50.3% female), with a mean age of 25.0 ± 5.7 years, were assessed for demographic characteristics, physical factors (hop performance, muscle strength, ankle and hip range of motion), and psychological factors (KOOS Pain and Symptoms subscales, Perceived Stress Scale, fear of reinjury) as well as the KOOS Sport and Recreation subscale and ACL-RSI scale. Backward linear regression models were used to evaluate factors associated with sports function and psychological readiness to RTS. RESULTS: Lower isokinetic knee extension peak torque (limb symmetry index) (B = 18.38 [95% CI, 3.01-33.75]), lower preinjury activity level (B = 2.00 [95% CI, 0.87-3.14]), greater knee pain (B = 0.90 [95% CI, 0.70-1.10]), shorter time between injury and reconstruction (B = 0.16 [95% CI, 0.05-0.26]), and greater fear of reinjury (B = 0.11 [95% CI, 0.01-0.20]) were associated with a worse KOOS Sport and Recreation subscore (R2 = 0.683). A shorter hop distance (B = 0.15 [95% CI, 0.00-0.29]) was associated with a lower ACL-RSI score (R2 = 0.245). CONCLUSION: A combination of knee muscle strength, activity level, knee pain, timing of surgery, and fear of reinjury accounted for approximately 70% of the variation in sports function at 1 year after ACLR. In contrast, there was only 1 weak association between physical function and psychological readiness to RTS at this time point. Thus, factors associated with current sports function are much better known than features related to psychological readiness to RTS.

What Factors Do Clinicians, Coaches, and Athletes Perceive Are Associated With Recovery From Low Back Pain in Elite Athletes? A Concept Mapping Study.

OBJECTIVE: Identify factors that elite sport clinicians, coaches, and athletes perceive are associated with low back pain (LBP) recovery. DESIGN: Concept mapping methodology. METHOD: Participants brainstormed, sorted (thematically), and rated (5-point Likert scales: importance and feasibility) statements in response to the prompt, "What factors are associated with the recovery of an elite athlete from low back pain?" Data cleaning, analysis (multidimensional scaling, hierarchical cluster analysis, and descriptive statistics), and visual representation (cluster map and Go-Zone graph) were conducted following concept mapping guidelines. RESULTS: Participants (brainstorming, n = 56; sorting, n = 34; and rating, n = 33) comprised 75% clinicians, 15% coaches, and 10% athletes and represented 13 countries and 17 sports. Eighty-two unique and relevant statements were brainstormed. Sorting resulted in 6 LBP recovery-related themes: (1) coach and clinician relationships, (2) inter-disciplinary team factors, (3) athlete psychological factors, (4) athlete rehabilitation journey, (5) athlete non-modifiable risk factors, and (6) athlete physical factors. Participants rated important recovery factors as follows: athlete empowerment and psychology, coach-athlete and athlete-clinician relationships, care team communication, return-to-sport planning, and identifying red flags. CONCLUSION: Factors perceived as important to LBP recovery in elite athletes align with the biopsychosocial model of community LBP management. Clinicians should consider that an athlete's psychology, relationships, care team communication, and rehabilitation plan may be as important to their LBP recovery as the formulation of a diagnosis or the medications or exercises prescribed.

Validation of the ACL-RSI Scale in Pediatric and Adolescent Patients.

BACKGROUND: The Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale is a 12-item questionnaire assessing psychological readiness to return to sport after anterior cruciate ligament reconstruction. It has been validated for use in adults in multiple languages and in an abbreviated 6-question short form. Additionally, literature has been published using this scale in pediatric and adolescent populations, however it has not yet been validated for use with them. PURPOSE: To validate the ACL-RSI scale for use with pediatric and adolescent patients. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 2. METHODS: Scores of 6- and 12-item ACL-RSI scales for patients undergoing return-to-sport readiness testing 6 to 8 months after anterior cruciate ligament reconstruction were analyzed. Convergent validity testing was performed against the International Knee Documentation Committee (IKDC)/Pediatric IKDC score, Single Assessment Numeric Evaluation (SANE) score, and peak torque asymmetry of knee flexion and extension using Spearman correlations. Discriminant validity testing was performed against age (Spearman correlation), body mass index (Spearman correlation), and sex (Mann-Whitney U test). Reliability testing was performed by calculating Cronbach's alpha. Floor and ceiling effects were assessed by calculating the number of minimum and maximum scores in the cohort. RESULTS: A total of 51 patients were included in the final analysis. The mean age at surgery was 15.2 ± 2.2 years, and 51.0% were female. The 6- and 12-item ACL-RSI scales demonstrated a strong significant positive correlation with IKDC/Pediatric IKDC scores (R = 0.723 and 0.717, respectively; P < .001) and moderate significant positive correlation with Single Assessment Numeric Evaluation scores (R = 0.516 and 0.502, respectively; P < .001) Age at surgery, body mass index, and sex were not correlated with either ACL-RSI scale. Cronbach's alpha values of the 12- and 6-item ACL-RSI scales in this population were 0.959 and 0.897, respectively. For both the 12- and the 6-item ACL-RSI scales, no floor or ceiling effects were found as the minimum score (0) was not observed in either version, and the maximum score (100) was only observed twice (3.9%) in both versions. CONCLUSION: The ACL-RSI scale is valid to use with pediatric and adolescent patients. The 6-item scale may be a better choice because it has fewer redundancies and minimizes the risk of questionnaire fatigue.

The ALR-RSI score can be used to evaluate psychological readiness to return to sport after acute Achilles tendon tear.

PURPOSE: The return to sport is one of the main goals following Achilles tendon tear repair. Several psychological factors influence the return to sport after a sports injury. The traditional tools to assess the return to sport do not take into account psychological factors. The ankle ligament reconstruction-return to sport injury (ALR-RSI), validated for ankle instability, is a score to evaluate psychological readiness to return to sport. The goal of this study was to validate the ALR-RSI score for the assessment of the readiness to return to sport after Achilles tendon repair. METHODS: The ALR-RSI score, adapted from the anterior cruciate ligament-return to sport injury (ACL-RSI) score used following knee ligament reconstruction, was validated according to the international COSMIN methodology. Patients operated for Achilles tendon repair responded to the questionnaire during the rehabilitation period. The EFAS, FAAM and VISA-A scores were used as reference questionnaires. RESULTS: A total of 50 patients were included. The ALR-RSI score was strongly (r > 0.5) correlated to the EFAS score: r = 0.68 [0.50-0.80] the FAMM sport score: r = 0.7 [0.52-0.84] the FAAM AVQ score (r = 0.6 [0.35-0.78]), and the VISA-A score (r = 0.54 [0.26-0.76]). The discriminant validity was good with the ALR-RSI, which was significantly lower in the patients that did not return to sport: 60.7 (40-81.4) compared to those that did: 83.2 (64.3-100) p = 0.001. Reproducibility was excellent with an intra-class correlation coefficient ρ of 0.99 [097-1.00]. The internal consistency was excellent (alpha coefficient = 0.95). CONCLUSION: The ALR-RSI score provides a valid, reproducible assessment of the psychological readiness to return to sport in patients who undergo surgical Achilles tendon suture repair.
