To combine the evidence from studies investigating the efficacy of unimodal perioperative care-components to form and implement an enhanced, evidence-based, cross-continuum, recovery program after total joint replacements to benefit both patients and society.
The experimental approach is a 4-phased model with initial quantification of problem areas. The key findings from this phase have been: substantial knee-extension strength-deficits early after surgery that may or may not resolve over time – but relate to post-operative knee swelling – large variability in indication and regimen for outpatient rehabilitation, and that surgical as well as rehabilitation traditions and myths determine clinical practice more than evidence-based principles. This phase has been followed by a second phase, in which we have investigated the preliminary efficacy of various exercise and surgical modalities aimed at identified problem areas, or developed and validated technology, such as the elastic exercise band-technology (please see pmrc.dk/exercise-adherence/), aimed at identified problem areas. The key findings from this phase have been: no symptom exacerbation by early implementation of progressive resistance training, increased voluntary activation of the quadriceps muscle during fatiguing contractions shortly after surgery, and validated technology that can objectively monitor adherence to home-based exercise.
Currently, the strategy has a strong focus on phase-three, large-scale exploratory or confirmatory studies, using prospective cohorte or randomized controlled trial-designs, respectively, to investigate the effectiveness or efficacy of e.g. various anesthesia and analgesia, different drugs to reduce the surgical stress response, different surgical procedures and perioperative principles, as well as different postoperative exercise therapy-modalities in multi-center, cross-continuum, collaboration with the municipalities around the Copenhagen area. Efforts towards national implementation will follow in phase four.
The research strategy involves ongoing collaboration with frontline research groups and programs, including: The Lundbeck Foundation Centre for Fast-Track Hip and Knee Replacements, Copenhagen, Denmark, Clinical Orthopedic Research Hvidovre, Copenhagen (CORH), Section of Surgical Pathophysiology, Rigshospitalet, Copenhagen,Research Unit, Center for Elective Surgery, Silkeborg, Denmark, Research Unit for General Practice in Aalborg, Aalborg University, Denmark, Health and Rehabilitation Research Institute, Auckland University of Technology, Auckland New Zealand, and the municipalities Hvidovre, Brøndby, and Copenhagen.
