Technology-assisted rehabilitation following total knee or hip replacement for people with osteoarthritis: a systematic review and meta-analysis.

ABSTRACT: BACKGROUND:To evaluate the effectiveness and safety of technology-assisted rehabilitation following total hip/knee replacement (THR/TKR). METHODS:Six electronic databases were searched without language or time restrictions for relevant studies: MEDLINE, EMBASE, Cochrane Library, CINAHL, SPORTDiscus, Physiotherapy Evidence Database (PEDro); from inception to November 7th, 2018. Two reviewers independently applied inclusion criteria to select eligible randomised controlled trials (RCTs) that investigated the effectiveness of technology-based interventions, compared with usual care or no intervention for people undergoing THR/TKR. Two reviewers independently extracted trial details (e.g. patients' profile, intervention, outcomes, attrition and adverse events). Study methodological quality was assessed using the PEDro scale. Quality of evidence was critically appraised using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS:We identified 21 eligible studies assessing telerehabilitation, game- or web-based therapy. There were 17 studies (N?=?2188) in post-TKR rehabilitation and 4 studies (N?=?783) in post-THR rehabilitation. Compared to usual care, technology-based intervention was more effective in reducing pain (mean difference (MD): -?0.25; 95% confidence interval (CI): -?0.48, -?0.02; moderate evidence) and improving function measured with the timed up-and-go test (MD: -7.03; 95% CI: -?11.18, -?2.88) in people undergoing TKR. No between-group differences were observed in rates of hospital readmissions or treatment-related adverse events (AEs) in those studies. CONCLUSION:There is moderate-quality of evidence showed technology-assisted rehabilitation, in particular, telerehabilitation, results in a statistically significant improvement in pain; and low-quality of evidence for the improvement in functional mobility in people undergoing TKR. The effects were however too small to be clinically significant. For THR, there is very limited low-quality evidence shows no significant effects.

Project description:Reduced external knee adduction moments in the second half of stance after total hip replacement have been reported in hip osteoarthritis patients. This reduction is thought to shift the load from the medial to the lateral knee compartment and as such increase the risk for knee osteoarthritis. The knee adduction moment is a surrogate for the load distribution between the medial and lateral compartments of the knee and not a valid measure for the tibiofemoral contact forces which are the result of externally applied forces and muscle forces. The purpose of this study was to investigate whether the distribution of the tibiofemoral contact forces over the knee compartments in unilateral hip osteoarthritis patients 1 year after receiving a primary total hip replacement differs from healthy controls. Musculoskeletal modeling on gait was performed in OpenSim using the detailed knee model of Lerner et al. (2015) for 19 patients as well as for 15 healthy controls of similar age. Knee adduction moments were calculated by the inverse dynamics analysis, medial and lateral tibiofemoral contact forces with the joint reaction force analysis. Moments and contact forces of patients and controls were compared using Statistical Parametric Mapping two-sample t-tests. Knee adduction moments and medial tibiofemoral contact forces of both the ipsi- and contralateral leg were not significantly different compared to healthy controls. The contralateral leg showed 14% higher medial tibiofemoral contact forces compared to the ipsilateral (operated) leg during the second half of stance. During the first half of stance, the lateral tibiofemoral contact force of the contralateral leg was 39% lower and the ratio 32% lower compared to healthy controls. In contrast, during the second half of stance the forces were significantly higher (39 and 26%, respectively) compared to healthy controls. The higher ratio indicates a changed distribution whereas the increased lateral tibiofemoral contact forces indicate a higher lateral knee joint loading in the contralateral leg in OA patients after total hip replacement (THR). Musculoskeletal modeling using a detailed knee model can be useful to detect differences in the load distribution between the medial and lateral knee compartment which cannot be verified with the knee adduction moment.

Project description:BackgroundA patient-engagement and pathway-management program for patients undergoing primary total hip and knee replacement was evaluated. Health-service and multimedia features supported by technology were integrated with existing enhanced recovery after surgery (ERAS) practices. The primary objective was to demonstrate the impact on length of stay. The secondary objective was to assess the impact on clinical, patient-focused, and financial outcomes.MethodsTwo thousand and eighty consecutive patients undergoing primary total hip replacement (n = 1,034) and total knee replacement (n = 1,046) were classified into "pre-program" (retrospectively assessed [n = 1,038]) and "program" (prospectively assessed [n = 1,042]) cohorts. Patients in the program cohort were subdivided according to those who were eligible for criteria-based outreach support (OS) (n = 401) and those who were ineligible for this service (NOS) (n = 641). Clinical outcomes were assessed for all patients, and patient-focused outcomes were assessed for a subset (n = 223).ResultsThe mean reduction in length of stay ranged from 20% (1.2 days) to 42% (2.5 days) following total hip replacement and from 9% (0.6 day) to 31% (2 days) following total knee replacement (p < 0.001). Clinical outcomes (readmissions, complications, emergency department re-attendance rates) were not significantly negatively impacted. The Oxford Hip Score had numerically larger improvement after total hip replacement in the OS group than in the pre-program group (4.1-point increase), and the Oxford Knee Score had numerically larger improvement after total knee replacement in the NOS group than in the pre-program group (0.8-point increase). The patients in the program cohort (either OS or NOS) rated overall health gain as higher than those in the pre-program cohort (gain in numerical rating scale, 1.4 points for patients managed with total hip replacement, 0.6 points for patients managed with total knee replacement). Older patients and those with higher comorbidity indices benefited most with respect to length of stay and multiple clinical outcomes. Patient experience was significantly improved across domains (p < 0.001 to p = 0.003). Potential savings for patients managed with total hip replacement (£401.64 [$267.76] per patient) exceeded estimated program charges of £50 [$33.33] to £60 [$40] per patient, whereas the potential savings for patients managed with total knee replacement (£76.67 [$51.11] per patient) were sufficient to achieve a reduction of total system costs.ConclusionsTechnology-enabled programs may deliver enhanced care at lower costs for patients undergoing lower-limb arthroplasty. Shorter durations of inpatient stay without a negative impact on clinical outcomes and improved patient-focused outcomes and experience can deliver substantial value that can be especially beneficial for older patients and those with greater medical complexity.Level of evidenceTherapeutic Level III.

Project description:Computer assisted surgery was pioneered in early 1990s. The first computer assisted surgery (CAS) total knee replacement with an imageless system was carried out in 1997. In the past 25 years, CAS has progressed from experimental in vitro studies to established in vivo surgical procedures.A comprehensive body of evidence establishing the advantages of computer assisted surgery in knee and hip arthroplasty is available. Established benefits have been demonstrated including its role as an excellent research tool. Its advantages include dynamic pre-operative and per-operative assessment, increased accuracy in correction of deformities, kinematics and mechanical axis, a better alignment of components, better survival rates of prostheses and a better functional outcome. Adoption of computer navigation in the hip arthroplasty is still at an early stage compared to knee arthroplasty, though the results are well documented. Evidence suggests improved accuracy in acetabular orientation, positioning, hip offset and leg length correction.Among the orthopaedic surgeons, navigated knee arthroplasty is gaining popularity though slowly. The uptake rates vary from country to country. The Australian joint registry data shows increased navigated knee arthroplasty from 2.4% in 2003 to 28.6% in 2015 and decreased revision rates with navigated knee arthroplasty in comparison with traditional instrumented knee arthroplasty in patient cohort under the age of 55 years.Any new technology has a learning curve and with practice the navigation assisted knee and hip arthroplasty becomes easy. We have actively followed the evidence of CAS in orthopaedics and have successfully adopted it in our routine practice over the last decades. Despite the cautious inertia of orthopaedic surgeons to embrace CAS more readily; we are certain that computer technology has a pivotal role in lower limb arthroplasty. It will evolve to become a standard practice in the future in various forms like navigation or robotics.
