Background: Total knee replacement (TKR) is the commonest surgical procedure for patients with severe pain and impaired physical function following end stage knee osteoarthritis. The hip abductors are well renowned in stabilization of the trunk and hip during walking, maintaining the lower limb position, and transferring the forces from the lower limbs to the pelvis. Objective: To assess the efficacy of hip abductor strengthening exercise on functional outcome using performance based outcome measures following total knee replacement. Methods: An observer blinded randomized pilot trial design was conducted at Manipal hospital, Bangalore, India. Participants designated for elective TKR were randomized to experimental group hip abductor strengthening along with standard rehabilitation (n=10) or control group standard rehabilitation alone (n=10). Participants followed for one year to assess physical function using performance based outcomes, such as timed up and go test, single leg stance test, six minute walk test, knee extensor strength and hip abductor strength. Result: Eighteen participants with a mean age of 63.1 ± 5.5 years (8 Males and 10 Females) completed the study. Improvement in hip abduction strength, single leg stand test was superior in hip abductor strengthening group at 3 months and 1 year when compared to standard rehabilitation alone. Conclusion: Hip abductor strengthening showed superior improvements in single leg stance test and six minute walk test. Hip abductor strengthening exercises has the potential to improve physical function following total knee replacement.

Rehabilitation services are less-studied aspects of the management following total knee arthroplasty (TKA) despite long-term suboptimal physical functioning and chronic deficits in muscle function. This paper describes the preliminary findings of a six-week (12 session) eccentrically-biased rehabilitation program targeted at deficits in physical function and muscle function, initiated one month following surgery. A quasiexperimental, one group, pretest-posttest study with thirteen individuals (6 female, 7 male; mean age years) examined the effectiveness of an eccentrically-biased rehabilitation program. The program resulted in improvements in the primary physical function endpoints (SF-36 physical component summary and the six-minute walk test) with increases of 59% and 47%, respectively. Muscle function endpoints (knee extension strength and power) also increased 107% and 93%, respectively. Eccentrically-biased exercise used as an addition to rehabilitation may help amplify and accelerate physical function following TKA surgery.

<p class="abstract"><strong>Background:</strong> Obesity is associated with an increased risk of osteoarthritis, and the incidence of obese patients requiring a total knee replacement (TKR) has increased in recent years. A high body mass index (BMI) may influence post‐TKR rehabilitation outcomes. The aim of the present study was to assess the effects of obesity on functional mobility outcomes following post‐TKR rehabilitation in Asian patients where BMI was not as high as those reported in similar studies performed other countries other than Asian.</p><p class="abstract"><strong>Methods:</strong> A total of 100 patients were categorized as normal weight (n=11), overweight (n=10), class I obese (n=28), or class II obese (n=32), class III obese (n=19). Patients were retrospectively followed up for 6 months after undergoing TKR followed by 2 months of active rehabilitation. Outcome measures were recorded at baseline and at the 2‐month and 6‐month follow-up assessments and included the Western Ontario and McMaster Universities Osteoarthritis Index and the following tests: functional reach, single‐leg stance, ten‐meter walk, timed up and go, chair rise, and stair climbing.<strong></strong></p><p class="abstract"><strong>Results:</strong> A 4×3 (group×time) repeated‐measures analysis of variance showed significant improvement in all of the outcome measures for all of the BMI groups at the 2‐month and 6‐month follow-up assessments (p&lt;0.05 for all). No significant intergroup differences at the 2‐month and 6‐month follow-up assessments were observed for any of the mobility measures except the functional reach and single‐leg stance (p&lt;0.05).</p><p class="abstract"><strong>Conclusions:</strong> Patients with class II/III obesity benefit from early post‐TKR outpatient rehabilitation and respond well. Also, the patients with lower BMIs showed significant improvements and patients with a high BMI might require additional balance-based exercises in their post-TKR rehabilitation protocols.</p>

Abstract Background and Purpose. Pain and physical function are core outcome measures for people with osteoarthritis, and self-report questionnaires have been the preferred assessment method. There is evidence suggestingthat self-reports of physical function represent what people experience when performing activities rather than their ability to perform activities. The purpose of this study was to examine the factorial validity of performance-specific assessments of pain and function. Subjects. The sample consisted of 177 participants who had osteoarthritis of the hip (n=81) or knee(n=96) and who were awaiting total joint arthroplasty. Methods. Through a cross-sectional design, participants performed 4 performance activities (self-paced walk test, stair test, Timed “Up & Go” Test, and Six-Minute Walk Test). Outcomes were time or distance (function) and pain ratings obtained immediately after each activity. The authors conceptualized 2 correlated factors, with pain items loading uniquely on 1 factor and functional items loading on the second factor, and uncorrelated error terms. Confirmatory factor analysis was applied. Results. Initial analysis yielded results consistent with the conceptualized model in this study with the exception of a nonzero correlation between the stair pain and function error terms. Dropping the stair test provided results consistent with the conceptualized model. Discussion and Conclusion. Given the limitations of self-report alone as a method of obtaining reasonably distinct assessments of pain and function, the extent to which performance-specific assessments could accomplish this goal was examined in this study. It was found that collectively the walk test, Timed “Up & Go” Test, and Six-Minute Walk Test yielded 2 factors consistent with the health concepts of pain and function. The authors believe that the application of these tests may provide clinicians and clinical researchers with more distinct impressions of pain and function that complement information from self-report measures.
