Subjective vs objective predictors of functional knee joint performance in anterior cruciate ligament-reconstructed patients-Do we need both?
چکیده انگلیسی


- Moderate-to-strong associations between objective and patient reported outcomemeasures in ACL-reconstructed are seen.
- Functional jump and maximal isometric muscle strength are central aspects of the associations.
- Only minor increases were observed when including kinematic data to the associations.
- The present associations may facilitate rehabilitation in ACL-patients.

BackgroundAssociations between objective and subjective measures of knee function may facilitate rehabilitation in ACL-patients.AimThe aim of this study is to investigate if a test-battery of functional and/or muscle outcomes are associated with Knee osteoarthritis outcome score (KOOS) subscales (Sport/Rec and QOL) in ACL-reconstructed patients.Methods23 hamstring auto-graft ACL-reconstructed men (mean age: 27.2 standard deviation 7.5 years, BMI: 25.4 standard deviation 3.2 time since surgery: 27 standard deviation 7 months) completed KOOS-questionnaire and an objective test-battery: (i) one-leg maximal jump for distance (OLJD), isometric maximal voluntary contraction (MVC) for (ii) knee extensors and (iii) flexors, and (iv) maximal counter movement jump (CMJ). Sagittal kinematic data were recorded during CMJ using a 6-camera Vicon MX system. Multilevel linear regression analysis was used to determine the strength of associations between KOOS parameters (Sport/Rec and QOL) that a priori were defined as dependent variables and 4 models of independent outcomes from the test-battery.ResultsModerate associations between OLJD and Sport/Rec (r2 = 0.26, p < 0.01) and QOL (r2 = 0.26, p < 0.01) were observed (Model 1). Adding knee extensor or flexor MVC to the analysis (Model 2) increased the strength of the associations (up to r2 = 0.53, p < 0.01, and r2 = 0.31, p = 0.02 for Sport/Rec and QOL, respectively). Adding both knee extensor and knee flexor MVC to the analysis (Model 3) did not improve the regression model and only minor increases were observed when including kinematic data of CMJ (Model 4).ConclusionModerate-to-large proportion (31-53%) of the variation in KOOS was explained by OLJD and MVC which may add to design effective future rehabilitation interventions for ACL-patients.
