“…Our previous study also showed a correlation between preoperative pain and self-reported QoL. 8) Moreover, the most significant predictor of patient dissatisfaction is persistent pain after surgery. 37) The results of these and the current study showed that patients continued to experience pain, albeit reduced, for up to 3 months after TKA, which possibly affected their QoL.…”

“…Pain after TKA was inversely correlated with time to recovery 27) and preoperative pain is correlated with self-reported physical function. 8) Patients experience pain for up to 3 months after surgery; however, even reduced pain can negatively affect physical function. Our results suggested that preoperative and postoperative pain control in patients could improve their physical function.…”

“…Our previous study showed correlations between preoperative performance-based physical function and self-reported physical function and QoL. 8) Dynamic balance and exercise capacity were powerful predictors of self-reported physical function and QoL. During the first month after TKA, physical performance and the results of self-reported questionnaires worsen substantially from preoperative conditions.…”

Background: Although total knee arthroplasty (TKA) is an effective treatment for knee osteoarthritis, assessment of postoperative outcomes remains unclear. This study aimed to identify postoperative physical performance factors that are correlated with self-reported physical function and quality of life (QoL) at 3 months after unilateral TKA. Methods: In total, 158 patients who underwent unilateral primary TKA completed performance-based physical function tests at 3 months after surgery, including Stair Climbing Tests (SCT), 6-Minute Walk Tests (6MWT), Timed Up and Go tests (TUG), and instrumental gait analysis. We also measured the isometric knee flexor and extensor strengths of the operated and non-operated knees. Self-reported physical function and QoL were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Euro-QoL Five Dimensions (EQ-5D) questionnaire, respectively. Results: Bivariate analyses showed that WOMAC function and EQ-5D were correlated with age, other self-reported measures, and performance-based measures. The WOMAC pain (r=0.71, p<0.001) showed a high positive correlation. While the EQ-5D (r=-0.7, p<0.001) showed a highly negative correlation with WOMAC function, WOMAC pain (r=-0.67, p<0.001) showed a moderately negative correlation with EQ-5D. In multivariate linear regression analyses, WOMAC pain, peak torque of the flexor of the non-operated knee, and reductions in extensor and stride length were associated with self-reported physical function, whereas WOMAC pain, SCT ascent, and cadence were associated with postoperative QoL. Conclusions: Physical performance factors were significantly associated with self-reported physical function and QoL in patients at 3 months after unilateral TKA. These findings suggest that performance-based physical function could be used to assess outcomes after TKA.

Background: This study aimed to identify the preoperative physical performance factors that predict gait speed and endurance 1 month after total knee arthroplasty (TKA). Methods: This prospective cohort study included all patients who underwent unilateral primary TKA in December 2014-2016. Before and at 1 month after TKA, gait variables, bilateral isometric knee extensor and flexor strength, and range of motion (ROM) (flexion and extension) of the operated knee were measured; further, a 6-minute walk test (6MWT), a Timed Up and Go (TUG) test, and a stair-climbing test (SCT) were conducted. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the EuroQoL 5-dimension (EQ-5D) questionnaire, and the visual analogue scale (VAS) of knee pain were also completed. Results: A total of 84 patients were included. Bivariate analyses showed that postoperative gait speed significantly and positively correlated with preoperative gait speed, gait cadence, ROM of knee flexion, and 6MWT, but significantly and negatively correlated with age and preoperative TUG test, SCT-descent, WOMAC-Function score, and VAS score. The postoperative 6MWT significantly and positively correlated with preoperative gait cadence and 6MWT, but significantly and negatively with preoperative body mass index (BMI), TUG test, SCT-ascent, and WOMAC-Function score. Linear regression analyses showed that age, preoperative ROM of knee flexion, and TUG test were independent predictors of postoperative gait speed, while preoperative BMI and 6MWT predicted postoperative 6MWT. Conclusion: These preoperative predictive factors will be useful in developing pre-and postoperative rehabilitation strategies aimed at improving gait function in the early stages after TKA.

“…Some studies have reported a moderate correlation between the general health of knee osteoarthritis patients, as assessed by the SF-36 Health survey, and gait parameters, such as single-limb support [ 19 ] and the intensity of gait cycles [ 17 ]. Similarly, advanced-stage patients’ QoL assessed by EQ-5D has been found to have a moderate correlation with walking and dynamic balance tests [ 20 ]. Due to these findings and to what we see in our clinical practice, we believe that gait alterations derived from physical impairment have a highly significant impact on our patient’s activities of daily living (ADLs) and, therefore, in their overall QoL.…”

Advanced knee osteoarthritis patients’ gait usually undergoes alterations leading to decreased mobility and lower functional performance, which can result in a worsening of their quality of life (QoL). While several authors have reported a moderate correlation between gait parameters and QoL assessed by generic questionnaires, the literature is scarce. This study aimed to explore the relationship between gait and QoL parameters assessed by a generic and a disease-specific questionnaire in patients with advanced knee osteoarthritis. In this single-centre, prospective, observational study, 129 patients with advanced knee osteoarthritis scheduled for elective total knee replacement were selected. The patients’ gait was evaluated by means of a validated wireless device while they walked 30 m at a comfortable speed. Patient function was also analysed using the Knee Society Score (KSS). QoL was measured with the EQ-5D and the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaires. Patients showed a mean walking speed of 0.95 ± 0.19 m/s, a mean cadence of 105.6 ± 9.9 steps/min, and a mean stride length of 1.25 ± 0.17 m on both legs. They presented poor knee status (KSS < 60) and poor QoL, with an EQ-5D of 0.44 ± 0.24 and a total KOOS of 29.77 ± 13.99. Positive low correlations (r <0.5, p <0.5) were found only between the speed, propulsion and stride length of both legs, and the overall and ADLs subscale scores of the total KOOS questionnaire. In conclusion, several gait parameters have a significant low correlation with the QoL of patients with advanced knee osteoarthritis, as assessed by an osteoarthritis-specific questionnaire.
