Preoperative Low Back Pain Affects Recovery in Knee Flexion Range of Motion Following Total Knee Replacement
ABSTRAKT
Background and Purpose: In this study, we examined the associations between presurgery patient profile and knee rnge of motion (ROM) outcomes at 6 and 12 months after total knee replacement (TKR). Methods: Knee ROM, demographic, health, and anthropometric variables were extracted from an existing database of patients who underwent primary TKR. Knee flexion and extension ROM at 6 and 12 months were the dependent variables. Age, sex, marital status, presurgical knee ROM, obesity, diabetes, hypertension, depression, low back pain (LBP) and number of other medical comorbidities were the independent variables. Multivariate linear regression analyses were conducted to examine the associations between these independent variables on the outcomes of knee flexion and extension ROM at 6 and 12 months after TKR. P values ≤ 0.05 were considered significant. Results: Poor presurgical knee flexion and presence of LBP were found to negatively affect knee flexion ROM at 6 and 12 months following TKR (P<0.05). Marital status and/or age predicted the recovery in knee extension ROM following TKR (P<0.05). Conclusions: The results of this study emphasize the need for presurgical interventions to maximize knee flexion ROM and to reduce the functional disability related to LBP to enhance the recovery of knee flexion ROM after TKR.
