Use of the forgotten joint score (FJS)-12 to evaluate knee awareness after isolated anterior cruciate ligament reconstruction with and without meniscus repair or partial meniscectomy

Eur J Orthop Surg Traumatol. 2022 Apr;32(3):413-418. doi: 10.1007/s00590-021-02991-5. Epub 2021 May 3.


Purpose: The aim of this study was to compare knee awareness, based on the FJS-12 score, among three patient groups: Anterior cruciate ligament reconstruction (ACLR), ACLR + meniscus repair and ACLR + partial meniscectomy. The relationship between FJS-12 scores and scores on other instruments (Lysholm Knee Scoring Scale, Tegner Activity Level Scale, KOOS and WOMAC) was also evaluated.

Methods: Forty-three patients were divided into group A (isolated ACLR) group B (ACLR + meniscectomy) and group C (ACLR + meniscus repair). Graft thickness, femoral tunnel width, tibial tunnel width, tibial screw thickness and follow-up time were evaluated in all three groups. The subjective knee scores (KOOS, WOMAC, Lysholm Knee Scoring Scale, Tegner Activity Level Scale and FJS-12) of the groups were then compared.

Results: FJS-12 scores of 43 patients were evaluated. The mean age was 26.1 ± 6.5 years (range: 18-40 years). Group A: 23; group B: 9 and group C include 11 patients. The mean FJS-12 score of group B (median: 100 [range: 98-100]) was higher than that the others. Spearman's rho test showed that the FJS-12 is highly compatible with the other scores.

Conclusion: According to this study, FJS-12 and the other scoring systems showed that ACLR with partial meniscectomy is the most effective surgical method to restore normal sensation in the knee.
