Abstract

Objectives: This study aims to examine the reliability, validity, and responsiveness of the Lysholm knee score (LKS) and Tegner activity scale (TAS) in Indonesian patients with anterior cruciate ligament reconstruction (ACLR).

Design: Cross-sectional study.

Setting: The LKS and TAS were translated into Indonesian through standardized procedures with the owners' permission, and the test-retest reliabilities, validities, and responsiveness were performed.

Participants: Data of LS, TAS, Short Form (SF)-36, as well as MRI results were collected from 206 patients with unilateral ACLR.

Main outcome measures: LKS and TAS.

Results: The questionnaires showed an adequate interclass correlation coefficient of 0.81-0.84 for the test-retest reliabilities, while an appropriate Cronbach's alpha value of 0.83 was obtained for internal consistency using LKS. They also had moderate-high correlations with the selected measures, which have similar constructs (r values, 0.44-0.68) except for the TAS with SF-36 physical function (PF; r value, 0.32). Meanwhile, low associations were observed with other measures with different constructs (r, 0.21-0.31). The results showed that Guyatt's responsiveness index for LKS and TAS changed in the SF-36's PF from 0.50 to 1.60 after one year.

Conclusions: The Indonesian version of LKS and TAS have acceptable reliabilities, validities, and responsiveness in ACLR patients.
