Background: The aim of this prospective study is to evaluate the degree of improvement in, and interrelationships between, performance-based function, gait, and patient-reported function 1 year after total hip arthroplasty (THA) in patients with primary hip osteoarthritis (OA). Materials and methods: Thirty-four patients with hip OA, with a mean age of 67 years (standard deviation, SD 9 years), and 25 age-and gender-matched healthy controls performed three performance-based functional tests, instrumented three-dimensional gait analysis, and completed the Hip disability and Osteoarthritis Outcome Score prior to and 1 year after THA. Effect sizes with 95 % confidence intervals were calculated as measures of the magnitude of improvement in performance after surgery. Results: Performance-based function displayed large improvements 1 year after THA. Overall gait patterns, quantified using a kinematic and a kinetic gait index, respectively, revealed moderate improvements in kinematics of the operated limb and kinetics of the contralateral limb. Patient-reported function displayed the largest improvement after surgery. Conclusions: The findings of this study suggest that objectively measured improvements in performance-based function and gait are not in line with patient-reported functional improvements, highlighting the importance of using both subjective and objective methods for evaluating function following THA.

Our objectives were to assess relationships between self-reported questionnaires and 2-minute walk test (2MWT) and timed get-up-and-go test (TUG) in preoperative total hip arthroplasty patients. A total of 162 patients completed the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36 and performed 2MWT and TUG. Correlations between self-reported questionnaires and 2MWT and TUG were mild to moderate, indicating that the 2MWT and TUG capture additional dimensions of preoperative total hip arthroplasty function not measured by the Western Ontario and McMaster Universities Osteoarthritis Index and Short Form 36. Use of walking aids, female sex, and presence of other painful joints were significantly associated with 2MWT, whereas older age and additional painful joints were significantly associated with TUG. These 2 tests are easy to perform in clinical practice and contribute to a comprehensive assessment of preoperative status.
Physical functioning four years after total hip and knee arthroplasty
Gait & posture
Our previous study showed that 6 months after total hip arthroplasty (THA) or total knee arthroplasty (TKA), patients reported having less difficulty with daily activities, showed better functional capacity, and performed activities in their natural environment faster compared to preoperatively. However, their actual daily activity level was not significantly improved. Six months is a rather short follow-up period and the discrepancy in recovery among different aspects of functioning might be explained by this limited duration of follow-up. The objective of the present study was to examine the recovery of different aspects of physical functioning at a follow-up nearly 4 years after THA/TKA. Special attention was given to the actual daily activity level, and whether it had increased 4 years after THA/TKA compared to 6 months postoperatively. Seventy-seven (35 hip, 42 knee) patients who were measured preoperatively and postoperatively (6 months after surgery) in a previous study were ...
The assessment of short-term functional outcomes after total hip arthroplasty: An original research
International journal of health sciences
Introduction–Total hip replacement (THR) is highly effective procedure for patients with hip joint deterioration by various conditions, as it relieves pain, improve mobility, attain stability with restoration of limb length and normal mechanics of hip joint, thus improving the standard of life for patient. Objective- The objectives of the study are: 1. To assess the short-term functional outcome in patients undergoing total hip arthroplasty post operatively. 2.Comparison of Harris hip score of present study with available literature. Material and methods- A total 40 patients with 53 hips with whom Total hip replacement was done, were followed up in this prospective observational study, on the basis of pre-defined inclusion and exclusion criteria. ANNOVA test and paired t test was done for statistical analysis. Significance level was fixed at P < 0.05. Result- In our study post op average HHS pain score increased to 37.95, thus improving patients gait and daily activities score to...

Our objective was to evaluate functional outcomes after surgery in a subgroup of patients presenting for hip and knee surgery who had low functional scores before surgery. One hundred twenty-seven unilateral total hip and knee arthroplasty patients were assessed preoperatively and 3 consecutive years after arthroplasty using: Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Short Form 36 (SF-36), and the Quality of Well-Being index scales. Patients were placed into 2 groups based on preoperative WOMAC function scores; 51 points or more, worse functioning group, and less than 51 points, higher functioning group. Regardless of time, the worse functioning group in both procedures performed worse on the Quality of Well-Being index, SF-36 (function score), SF-36 (social score), and WOMAC total and pain scores (P ≤ .0001). The greatest change (range, 2%-638%) for all variables in both groups for both procedures occurred during the first year. Patients that had severe/extreme functional impairment had worse 3-year outcomes compared with patients getting surgery when their functional levels were better.

The aim of our study was to investigate the relationship between self-reported and performance-based tests in the assessment of patients with total hip arthroplasty (THA). Methods: Ninety four patients (35 males, 59 females) were included in the study with mean age 57.1 ± 14.6 years. Patients performed four performance tests (Timed "Up & Go" Test, Sit to Stand Test, Self-paced Walk Test and Stair Test) and two self-reported measurements (Harris Hip Score [HHS] and SF-36 [36-Item Short Form Health Survey]) were preferred to assess patients. Results: There were varying correlations between performance tests and subscales of the SF-36 including physical function, energy/fatigue, pain, general health. Strong correlation was found between HHS and Timed "Up and Go"(r = −0.59, p < 0.001), self-paced walk test (r = −0.58, p < 0.001). Moderate correlation was found between HHS and sit to stand test (r = −0.406, p < 0.001), stair test (r = 0.32, p < 0.001). Conclusions: There were especially moderate-to-strong correlations between self-reported measurements and performance-based tests in the evaluation of patients with THA. Therefore, outcomes assessment after THA may include self-reported measurements or performance-based tests.
