Italian version of the anterior cruciate ligament-return to sport after injury scale (IT ACL-RSI): translation, cross-cultural adaptation, validation and ability to predict the return to sport at medium-term follow-up in a population of sport patients

Translation, Cross-Cultural Adaptation, and Validation of the Italian Version of the Shoulder Instability-Return to Sport After Injury (SI-RSI) Scale

OBJECTIVE

To culturally adapt and validate the Italian version of the Shoulder Instability-Return to Sport after Injury (SI-RSI-I) scale.

METHODS

The SI-RSI-I was developed by adapting the Anterior Cruciate Ligament-Return to Sport Index-Italian version and replacing the term "knee" with "shoulder." Subsequently, it underwent validation following COSMIN recommendations. The study involved athletic participants who experienced SI. They completed the SI-RSI-I together with other measurement instruments: Western Ontario Shoulder Instability Index, Kerlan-Jobe Orthopedic Clinic Score, EuroQol-5D-5L, and Numeric Pain Rating Scale. The following psychometric properties were investigated: structural validity, internal consistency, test-retest reliability, measurement error, and construct validity.

RESULTS

The study included 101 participants (age mean [SD] 28.5 [7.4] y; 83 males, 18 females). The SI-RSI-I showed a single-factor structure, excellent internal consistency (α = .935), and excellent test-retest reliability (ICC = .926; 95% CI, .853-.964). The standard error of measurement was 6.1 points, and the minimal detectable change was 17.0 points. Furthermore, SI-RSI-I demonstrated moderate to strong correlations with all reference scales, confirming 8 out of 9 (88.0%) hypotheses, thus establishing satisfactory construct validity.

CONCLUSION

The SI-RSI-I has demonstrated robust internal consistency, reliability, validity, and feasibility as a valuable scale for assessing psychological readiness to return to sport in Italian athletes with SI.

Anterior Cruciate Ligament Return to Sport after Injury Scale (ACL-RSI) Scores over Time After Anterior Cruciate Ligament Reconstruction: A Systematic Review with Meta-analysis

BACKGROUND

Psychological readiness is an important consideration for athletes and clinicians when making return to sport decisions following anterior cruciate ligament reconstruction (ACLR). To improve our understanding of the extent of deficits in psychological readiness, a systematic review is necessary.

OBJECTIVE

To investigate psychological readiness (measured via the Anterior Cruciate Ligament-Return to Sport after Injury scale (ACL-RSI)) over time after ACL tear and understand if time between injury and surgery, age, and sex are associated with ACL-RSI scores.

METHODS

Seven databases were searched from the earliest date available to March 22, 2022. Articles reporting ACL-RSI scores after ACL tear were included. Risk of bias was assessed using the ROBINS-I, RoB-2, and RoBANS tools based on the study design. Evidence certainty was assessed for each analysis. Random-effects meta-analyses pooled ACL-RSI scores, stratified by time post-injury and based on treatment approach (i.e., early ACLR, delayed ACLR, and unclear approach).

RESULTS

A total of 83 studies were included in this review (78% high risk of bias). Evidence certainty was 'weak' or 'limited' for all analyses. Overall, ACL-RSI scores were higher at 3 to 6 months post-ACLR (mean = 61.5 [95% confidence interval (CI) 58.6, 64.4], I2 = 94%) compared to pre-ACLR (mean = 44.4 [95% CI 38.2, 50.7], I2 = 98%), remained relatively stable, until they reached the highest point 2 to 5 years after ACLR (mean = 70.7 [95% CI 63.0, 78.5], I2 = 98%). Meta-regression suggests shorter time from injury to surgery, male sex, and older age were associated with higher ACL-RSI scores only 3 to 6 months post-ACLR (heterogeneity explained R2 = 47.6%), and this reduced 1-2 years after ACLR (heterogeneity explained R2 = 27.0%).

CONCLUSION

Psychological readiness to return to sport appears to improve early after ACL injury, with little subsequent improvement until ≥ 2-years after ACLR. Longer time from injury to surgery, female sex and older age might be negatively related to ACL-RSI scores 12-24 months after ACLR. Due to the weak evidence quality rating and the considerable importance of psychological readiness for long-term outcomes after ACL injury, there is an urgent need for well-designed studies that maximize internal validity and identify additional prognostic factors for psychological readiness at times critical for return to sport decisions.

Functional and Psychological Preparedness of Athletes Post ACL Repair

Objective

This study was conducted to see whether those who had anterior cruciate ligament (ACL) reconstructions on their dominant legs performed better than those who had them on their nondominant legs 1-10 years after the surgery.

Materials and Methods

An examination of people who sustained injuries to their dominant (n = 25) and nondominant (n = 25) legs between 1 and 10 years after ACL repair was undertaken in a cross-sectional research with 50 people aged 20-38. Everyone takes the fear avoidance belief questionnaire for physical activity (FABQ-PA), the lower extremity functional scale (LEFS), and the anterior cruciate ligament return to sport after injury (ACL-RSI) survey.

Results

There was no statistically significant difference between the groups on the ACL-RSI, LEFS, and FABQ-PA (U = 254, P = 0.26; U = 314.4, P = 0.95; and U = 279.4, P = 0.53 correspondingly).

Conclusion

Functional performance and patient mental health should be evaluated 1-10 years after ACL surgery. However, there is no correlation between which leg was the dominant one and the results. As a result, it has been shown that both dominant and nondominant leg injuries heal similarly over time. Future studies should examine additional variables that affect healing and return-to-sport results to improve rehabilitation and optimize long-term functional outcomes for individuals after ACL repair.

Cross-Culturally Adapted Versions of Patient Reported Outcome Measures for the Lower Extremity

Background

A large number of patient reported outcome measures (PROMs) have been developed in the English language for various lower extremity orthopaedic pathologies. Twenty different PROMs were recommended for 15 specific musculoskeletal lower extremity pathologies or surgeries. However, the availability of cross-culturally adapted versions of these recommended PROMs is unknown.

Purpose

The purpose of this study was to identify the cross-culturally adapted versions of recommended PROMs for individuals experiencing orthopedic lower extremity pathologies or undergoing surgeries, and to identify the psychometric evidence that supports their utilization.

Study design

Literature Review.

Methods

PubMed, Embase, Medline, Cochrane, CINAHL, SPORTDisucs and Scopus were searched for cross-culturally adapted translated studies through May 2022. The search strategy included the names of the 20 recommended PROMs from previous umbrella review along with the following terms: reliability, validity, responsiveness, psychometric properties and cross-cultural adaptation. Studies that presented a non-English language version of the PROM with evidence in at least one psychometric property to support its use were included. Two authors independently evaluated the studies for inclusion and independently extracted data.

Results

Nineteen PROMS had cross-culturally adapted and translated language versions. The KOOS, WOMAC, ACL-RSL, FAAM, ATRS, HOOS, OHS, MOXFQ and OKS were available in over 10 different language versions. Turkish, Dutch, German, Chinese and French were the most common languages, with each language having more than 10 PROMs with psychometric properties supporting their use. The WOMAC and KOOS were both available in 10 languages and had all three psychometric properties of reliability, validity, and responsiveness supporting their use.

Conclusion

Nineteen of the 20 recommended instruments were available in multiple languages. The PROM most frequently cross-culturally adapted and translated were the KOOS and WOMAC. PROMs were most frequently cross-culturally adapted and translated into Turkish. International researchers and clinicians may use this information to more consistently implement PROMs with the most appropriate psychometric evidence available to support their use.

Validation and Application of a Spanish Version of the ALR-RSI Scale (Ankle Ligament Reconstruction-Return to Sport after Injury) in an Active Non-Athlete Population

The most recent scale to quantify psychological readiness before returning to sport is the ALR-RSI (Ankle Ligament Reconstruction-Return to Sport after Injury) scale. The aim of this study was the cross-cultural adaptation to Spanish and application of the ALR-RSI scale in a sample of active people who were not professional athletes, and to carry out an initial psychometric analysis of the functioning of the instrument in this sample. The sample consisted of 257 participants (161 men and 96 women) aged between 18 and 50 years. The adequacy of the model obtained in the exploratory study was confirmed, obtaining a model composed of one factor and 12 indicators in total. The estimated parameters were statistically significant (p < 0.05), and the factor loadings presented values higher than 0.5; thus, all indicators revealed a satisfactory saturation in the latent variable (convergent validity). Regarding internal consistency, the Cronbach's alpha value was 0.886 (excellent internal consistency). This study demonstrated that the ALR-RSI in Spanish is a valid and reproducible scale for evaluating psychological readiness to return to non-professional physical activity after ankle ligament reconstruction in the Spanish population.

Relationships between Jumping Performance and Psychological Readiness to Return to Sport 6 Months Following Anterior Cruciate Ligament Reconstruction: A Cross-Sectional Study

Background: Investigating the relationship between functional capacity and psychological readiness is of paramount importance when planning sport resumption following knee surgery. The aim of this study was to prospectively assess clinical and functional outcomes in athletes 6 months after primary anterior cruciate ligament (ACL) reconstruction and to evaluate whether jumping ability is related to psychological readiness to return to sport following ACL surgery. Methods: Patients who underwent ACL reconstruction were prospectively enrolled and evaluated pre-operatively and 6 months after surgery. Assessment included Lysholm score, International Knee Documentation Committee (IKDC) Subjective Knee Form, Tegner activity level, and the ACL−Return to Sport after Injury (ACL-RSI) scale. Jumping ability was instrumentally assessed by an infrared optical acquisition system using a test battery including mono- and bipodalic vertical jump and a side hop test. Patients were dichotomized by ACL-RSI into two groups: group A (ACL-RSI > 60), and group B (ACL-RSI < 60). Results: Overall, 29 males and two females from the original study group of 37 patients (84%) were available for clinical evaluation. Mean age at surgery was 34.2 years (SD 11.3). Mean body mass index (BMI) was 25.4 (SD 3.7). Mean overall Lysholm, IKDC, and ACL-RSI scores increased from pre-operatively (p < 0.001). No differences in Tegner score were reported (p = 0.161). Similarly, improvement in most variables regarding jumping ability were observed at follow-up (p < 0.05). According to ACL-RSI, 20 subjects were allocated in group A (ACL-RSI > 60), while 11 were allocated in group B (ACL-RSI < 60). A statistically significant difference in favor of patients in group A was recorded for the post-operative Lysholm and Tegner score, as well as Side Hop test LSI level (p < 0.05), while a trend for IKDC was observed without statistical significance (p = 0.065). Conclusions: Patients with higher values of ACL-RSI scores showed better functional and clinical outcomes as well as improved performance 6 months after ACL reconstruction

Translation, cross-cultural adaptation, and validation of the Italian version of the anterior cruciate ligament–return to sport after injury (ACL-RSI) scale and its integration into the K-STARTS test

Background

The timing of a return to sport (RTS) after anterior cruciate ligament reconstruction (ACLR) represents a major subject of debate in sports medicine practice. Recently, the Knee Santy Athletic Return to Sport (K-STARTS) composite test was validated. This consists of a battery of physical tests and a psychological evaluation using the anterior cruciate ligament–return to sport after injury scale (ACL-RSI). This study aimed to translate the ACL-RSI and K-STARTS from English to Italian and determine the scale’s reliability and validity in an Italian context.

Methods

The translation and cultural adaptation process was performed according to the guidelines for the cross-cultural adaptation of self-report measures. The patients were asked to fill an anonymized online form created for this purpose that included the KOOS, the Lysholm, the IKDC-SKF, and the Italian translation of the ACL-RSI (ACL-RSI-It). After 1 week, the attendees were asked to repeat the ACL-RSI-It to investigate the test–retest reliability.

Results

The final study population comprised 115 patients who underwent ACLR, with a mean follow-up of 37.37 ± 26.56 months. The ACL-RSI-It showed axcellent internal consistency (Cronbach’s α = 0.963), reliability (test–retest ICC = 0.966), and good construct validity (positive correlations with the other scales were above 75%).

Conclusions

The ACL-RSI-It is valid, reliable, and comparable to the original English version of the questionnaire for Italian-speaking patients. It can be used to assess the psychological readiness of patients for a RTS after primary and unilateral ACLR, and can be integrated into the Italian K-STARTS test.

Different timing in allograft and autograft maturation after primary anterior cruciate ligament reconstruction does not influence the clinical outcome at mid-long-term follow-up

PURPOSE

The use of allografts in primary anterior cruciate ligament reconstruction (ACLR) is increasing although they are still supposed to be associated to greater risk of re-rupture due to a slower and less efficient graft maturation. The aim of this prospective randomized controlled study was to compare the graft maturation after ACLR with allograft and autograft by MRI at 6- and 12-month follow-up and integrate these data with the functional and clinical results observed at 6-, 12- and 60-month follow-up.

METHODS

Fifty patients with indication to primary ACLR were randomly and equally divided into hamstring autograft or allograft tendon groups. The graft maturation was measured at 6- and 12-month follow-up by the SNQ score and other radiological parameters on MRI scans. Clinical and functional recovery was evaluated by Lysholm score, Visual Analogues Scale, Tegner activity scale and modified Cincinnati knee rating system at 6, 12 and 60 months after surgery to estimate the predictive value of the radiological parameters for clinical outcomes. Return-to-sport (ACL-RSI) was measured 60 months after surgery.

RESULTS

Three patients had retear of the neo-ligament (two from Auto group and one from Allo group). All the clinical/functional parameters significantly improved over time, with no statistically significant difference between the groups. At 6 months, the SNQ value was significantly higher in the Auto than in the Allo group (12.9 vs 7.9, p = 0.038), but at 12 months they were comparable (9.8 vs 10.4). The 6-month SNQ values did not correlate with the clinical scores, whereas the 12-month SNQ values significantly correlated with the Cincinnati score, Lysholm score and Tegner activity scale collected at 60-month follow-up.

CONCLUSION

No clinical or functional differences have been found between the two treatment groups, supporting the suitability of using allograft in primary ACLR, when available. The results at MRI scans showed a different graft maturation trend in the two groups, with allografts being more reactive in the first 6 months. MRI together with the subjective evaluation allows to evaluate objectively the status of the neo-ligamentization process and therefore helps the surgeon to dictate the individual time for return-to-sport.
