“…Similarly, Lee et al. 10 found excellent internal consistency for the FJS-12 score after ACL reconstruction (Cronbach’s alpha of 0.9), whereas being normally distributed and showing lower ceiling effects compared to the Lysholm and Tegner scales. Because the FJS-12 may enable clinicians to assess and monitor functional outcomes over a prolonged period using the same metric, this validated tool seems useful to measure multiple facets of ACL surgery, including the potential development of posttraumatic osteoarthritis.…”

“…6,7,9 Behrend et al 9 showed high internal consistency (Cronbach's alpha of 0.95) and considerably less ceiling effects than most Knee Injury and Osteoarthritis Outcome Scores and all Western Ontario and McMaster Universities Arthritis Index subscales.

“…A previous validation study for the FJS-12 in ACL reconstruction patients reported a weak correlation with Lysholm scores (Spearman’s correlation = 0.23) but did not assess other domains. 10 It remains unclear why this PROM showed a smaller correlation, but the high observed ceiling effect of the Lysholm score may have affected this outcome. Taken these factors into account, the FJS-12 seems to provide a robust approach in evaluating overall knee function after ACL primary repair.…”

“…Nonetheless, the present study indicates that the FJS-12 had considerably less ceiling effect than the Lysholm, modified Cincinnati, and IKDC Subjective scores, which When specifically looking at previous studies validating the FJS-12 after ACL reconstruction, both studies showed less ceiling effect of the FJS-12 (range, 8.5%-15.5%) than that found in the present study (21.9%). 8,10 One of the potential explanations for this finding might be related to the invasiveness of both techniques. By preserving native tissue, 26 we have previously shown that repair patients may have significantly less joint awareness than those treated with ACL reconstruction (85.3 vs. 74.5, respectively).…”

“…More recently, this tool has also been introduced to evaluate clinical outcomes after ACL reconstruction. 8 Although the FJS-12 has been shown to be a valid and responsive outcome metric after ACL reconstruction, 9 , 10 this questionnaire has not yet been validated to evaluate joint awareness after primary ACL repair. As repair procedures are increasingly advocated in the orthopaedic literature, 11 it is important to validate this outcome metric.…”

Purpose: To validate the Forgotten Joint Score-12 (FJS-12) as a subjective outcome metric for patients undergoing arthroscopic primary anterior cruciate ligament (ACL) repair. Methods: In this retrospective study, all patients undergoing primary ACL repair for complete isolated proximal tears between 2008 and 2018 were eligible for inclusion. Patients were contacted and asked to complete the FJS-12, Lysholm Knee Score, modified Cincinnati score, Single Assessment Numeric Evaluation (SANE), Subjective International Knee Documentation Committee (IKDC), and Anterior Cruciate Ligament Return to Sport after Injury (ACL-RSI) scale at a minimum of 1 year of follow-up. Internal consistency, convergent validity, and ceiling effects were analyzed. Results: Ninety-six patients could be included (62%), with a mean FJS-12 score of 86.9 AE 14.0 (range, 31.3-100). The FJS-12 showed reliable internal consistency (Cronbach's alpha ¼ 0.89). Construct validity was moderate to strong (r ¼ 0. 621-0.702). Ceiling effect for the FJS-12 was 21.9%, which was lower than for the Lysholm (44.6%), modified Cincinnati (45.1%), equal to the IKDC subjective (21.9%), and SANE score (22.0%) but higher compared to the ACL-RSI (12.8%). Furthermore, internal consistency for the other scores was also good to excellent (range Cronbach's alpha ¼ 0.627-0.953). Conclusion: The FJS-12 shows high internal consistency and construct validity after primary ACL repair. Furthermore, this metric showed equal or less ceiling effect than most other scores, although still notable. This study suggests that the FJS-12 is an easy and validated outcome metric to evaluate subjective primary repair outcomes. Level of Evidence: Level III, diagnostic study.
