Patients with anterior cruciate ligament reconstruction (ACLR) areoften psychologically and physically under-prepared for sport participation. This study compared readinessto return to sport based oncompletion ofadvanced training after ACLR. Patients with ACLR who self-selectedparticipation in a 6-week group-format advanced training program (TRAINING)were compared to age- and sex-matched patients who did not participate (NoTRAINING). Each group had 23 participants (14 females). Advanced training consisted of plyometric, strengthening and agility exercises. Baseline and follow-up testing includedpsychologicalmeasures (Anterior Cruciate Ligament Return to Sport after Injury, ACL-RSI; Tampa Scale for Kinesiophobia, TSK-11; Knee Activity Self-Efficacy, KASE; and fear intensity for the primary fear-evoking task or situation) and a hop test battery.Return to sport criteria were ACL-RSI score ≥70 points and limb symmetry index ≥90% on all hop tests. At follow-up, KASE score was higher in TRAINING than NoTRAINING (92.7 vs 89.1 points; respectively), but ACL-RSI, TSK-11 and fear intensity scoreswere not significantly different between groups. Return to sport criteriapassing rate was not significantly differentbetween groups at baseline (TRAINING: 13%, NoTRAINING: 30%) or follow-up (TRAINING: 52%, NoTRAINING: 43%); however, thedistribution of criteria met at follow-up differed with more patients in TRAINING than NoTRAINING meeting hop test criteria (30% vs 4%; respectively) and more patients in NoTRAININGthan TRAINING failing to meet any criteria(25% vs 0%, respectively). Clinical significance:Advanced training after ACLR facilitated readiness for sport participation by improving confidence and hop performance, but may not have a preferential effect on fear.

Decreased psychological readiness for sport may contribute to poor return-to-sport rates after anterior cruciate ligament reconstruction (ACLR). Though advanced rehabilitation is used to improve functional readiness for sport after ACLR, the effect of advanced rehabilitation on psychological readiness is unknown.To examine changes in psychological and functional measures and readiness for sport based on these measures in patients with ACLR following advanced group training.In this retrospective cohort study, patients with primary ACLR enrolled in a 5-week group training program after completing traditional physical therapy. Data collection pretraining and posttraining included demographic information, the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale, and single-leg hop testing (single, triple, crossover triple, and timed hops). Readiness for sport was based on criteria for the ACL-RSI scale score (low threshold, 56 points or greater; high threshold, 75 points or greater) and hop tests (90% or greater limb symmetry).Fifty-eight patients (21 male) participated. Mean ACL-RSI scale scores, mean hop test limb symmetry, and the proportion of patients meeting ACL-RSI and hop test readiness-for-sport criteria significantly improved from pretraining to posttraining. Posttraining ACL-RSI scale scores were correlated with single hop (r = 0.269) and triple hop (r = 0.275) limb symmetry, yet changes in the measures were not significantly correlated. After training, only 53.4% (lower ACL-RSI threshold) or 37.9% (higher ACL-RSI threshold) of the sample met both psychological and functional readiness criteria.Advanced group training following ACLR improved psychological and functional outcomes; however, further, individualized intervention may be needed to address residual deficiencies in some patients.Therapy, level 2b.

Background: In patients who have undergone anterior cruciate ligament reconstruction (ACLR), the effect of neuromuscular re-education (NMR) programs on standard hop tests outcomes, including limb symmetry indices (LSIs), is unknown. Hypothesis: Both legs will show improvement in hop test–measured units after neuromuscular training, but the involved leg will show relatively greater improvement leading to improved limb symmetry. Patients younger than 18 years will show more improvement than patients who are older. Study Design: Retrospective cohort study. Level of Evidence: Level 3. Methods: Patients self-selected their participation in this NMR program, which was completed after traditional outpatient physical therapy. Pre– and post–hop test scores were recorded as the primary outcome measure. Results: Seventy-one patients met the inclusion criteria and completed hop testing. Overall, the involved leg showed significant improvements (pretest/posttest) for single-leg hop (138.30 cm/156.89 cm), triple crossover hop (370.05 cm/423.11 cm), and timed hop (2.21 s/1.99 s). Similarly, on the uninvolved leg, improvements were seen for the single-leg hop (159.30 cm/171.87 cm) and triple crossover hop (427.50 cm/471.27 cm). Overall mean limb symmetry improved across all 4 hop tests, but there was significant improvement only on the single-leg hop (87% pretest to 92% posttest). Patients younger than 18 years showed mean significant LSI improvement on the triple crossover hop. Conclusion: Utilizing an intensive 6-week NMR program after ACLR prior to return to sport can improve quantitative hop test measurements. Patients younger than 18 years had greater improvement than those 18 years and older. Clinical Relevance: Advanced NMR programs can be successfully utilized in the postoperative ACLR setting to improve quantitative limb symmetry.

Background: Fear of reinjury is common after anterior cruciate ligament reconstruction (ACLR) and often deters a return to preinjury sport participation. A better understanding of injury-related fear is needed to inform rehabilitation strategies. Purpose/Hypothesis: The purpose of this study was to (1) identify individual fear-evoking tasks or situations, (2) compare the intensity and amount of change relative to other injury-related fears (reinjury, knee giving way, and knee pain) after completion of a return-to-sport training program, and (3) determine whether standardized questionnaires can identify the intensity of fear for the individual fear-evoking task or situation and for fear of reinjury. The hypothesis was that the task or situation that evokes fear would vary across patients and the intensity of that fear would be higher and show less change after return-to-sport training compared with other injury-related fears. Study Design: Case series; Level of evidence, 4. Methods: Participants included 33 patients (15 males; mean age, 18 years) with ACLR who enrolled in a group-format return-to-sport training program. Questionnaires completed before and after return-to-sport training included items to specify fear-evoking tasks or situations, items to rate the intensity of various injury-related fears, the Anterior Cruciate Ligament Return to Sport after Injury scale (ACL-RSI), and the Tampa Scale for Kinesiophobia (TSK-11). Results: The most common fear-evoking task or situation was cutting, followed by contact, jumping, and other. Intensity of fear-evoking task or situation was higher than other injury-related fears, but all fears decreased in intensity after training. The ACL-RSI score better identified the intensity of fear for the individual fear-evoking task or situation and for fear of reinjury than did the TSK-11 score. Conclusion: Activities that evoke fear vary across patients, but fear of cutting is common. The intensity of common fears after ACLR decreased after advanced group training, and large effect sizes were seen for nearly all examined fears. Fear of reinjury and intensity of individually feared tasks may be better reflected in the ACL-RSI score than the TSK-11 score.

Context: A sports injury has both physical and psychological consequences for the athlete. A common postinjury psychological response is elevated fear of reinjury. Objective: To provide an overview of the implications of fear of reinjury on the rehabilitation of athletes, including clinical methods to measure fear of reinjury; the impact of fear of reinjury on rehabilitation outcomes, including physical impairments, function, and return to sports rate; and potential interventions to address fear of reinjury during rehabilitation. Evidence Acquisition: PubMed was searched for articles published in the past 16 years (1990-2016) relating to fear of reinjury in athletes. The reference lists of the retrieved articles were searched for additionally relevant articles. Study Design: Clinical review. Level of Evidence: Level 3. Results: Fear of reinjury after a sports injury can negatively affect the recovery of physical impairments, reduce self-report function, and prevent a successful return to sport. Athletes with high fear of reinjury might benefit from a psychologically informed practice approach to improve rehabilitation outcomes. The application of psychologically informed practice would be to measure fear of reinjury in the injured athletes and provide interventions to reduce fear of reinjury to optimize rehabilitation outcomes. Conclusion: Fear of reinjury after a sports injury can lead to poor rehabilitation outcomes. Incorporating principles of psychologically informed practice into sports injury rehabilitation could improve rehabilitation outcomes for athletes with high fear of reinjury.
