Show moreBackground: Physiotherapy is a proven effective treatment strategy after total knee and hip arthroplasty (TKA/THA), however there is considerable practice variation regarding its timing, content and duration. This study aims to compare the (cost-) effectiveness of a standardized, treat-to-target postoperative physiotherapy strategy with usual postoperative care.Methods: Using a cluster randomized study design, consecutive patients scheduled for a primary TKA/THA in 18 hospitals in the Netherlands will be assigned to the treat-to-target physio therapy strategy or usual postoperative care. With the treat-to-target strategy a standardized, individually tailored, exercise program is aimed at the attainment of specific functional milestones. Assessments are done at baseline, 6 weeks and 3, 6, 9 and 12 months follow up. The primary outcome will be the Knee injury / Hip disability and Osteoarthritis Outcome Score - Physical Function Short Form (KOOS-PS / HOOS-PS) at 3 months follow up. Secondary outcomes are the numeric rating scale for pain, the Oxford Knee and Hip Scores, performance-based test and the EuroQol 5D-5L for quality of life. Healthcare use, productivity and satisfaction with postoperative care are measured by means of questionnaires. In total, 624 patients will be needed of which 312 TKA and 312 THA patients.Discussion: The study will provide evidence concerning the (cost-) effectiveness of the treat-to-target postoperative physiotherapy treatment compared to usual postoperative care. The results of this study will address an important evidence gap and will have a significant impact in daily practice of the physio therapist. Show less

Show moreObjective We conducted a meta-analysis to estimate the risk of adverse events, life expectancy, and event-free life expectancy after the Ross procedure in adults. Methods We searched databases for reports evaluating the Ross procedure in patients aged more than or equal to 16 years of age. A microsimulation model was used to evaluate age- and gender-specific life expectancy for patients undergoing the Ross procedure. Results Data were pooled from 63 articles totaling 19 155 patients from 20 countries. Perioperative mortality was 2.5% (95% confidence interval [CI]: 1.9-3.1; N = 9978). We found a mortality risk of 5.9% (95% CI: 4.8-7.2) at a mean follow-up of 7.2 years (N = 7573). The rate of perioperative clinically significant bleeding was 1.0% (95% CI: 0.1-3.0); re-exploration for bleeding 4.6% (95% CI: 3.1-6.3); postoperative clinically significant bleeding from 30 days until a mean of 7.1 years was 0.5% (95% CI: 0.2-1.0). At a mean of 6.9 years of follow-up, reintervention rate of any operated valve was 7.9% (95% CI: 5.7-10.3). The risk of valve thrombosis was 0.3% (95% CI: 0.2-0.5) at 7.6 years; peripheral embolism 0.3% (95% CI: 0.2-0.4) at 6.4 years; stroke 0.9% (95% CI: 0.7-1.2) at 6.5 years; and endocarditis 2.1% (95% CI: 1.6-2.6) at 8.0 years. Microsimulation reported a 40-year-old undergoing the Ross procedure to have a life expectancy of 35.4 years and event-free life expectancy of 26.6 years. Conclusions Ross procedure in nonelderly adults is associated with low mortality and low risk of adverse events both at short- and long-term follow-up. The surgical community must prioritize a large, expertize-based randomized controlled trial to definitively address the risks and benefits of the Ross procedure compared to conventional aortic valve replacement.
