Patients outside the age range of 18–85 years were excluded. All patients who underwent primary total knee arthroplasty for primary end-stage osteoarthritis were included.
APPTRENDS TRIAL TRIAL
We hypothesized that in long term, the app-based exercise program is as good as the control group performing physiotherapy.Ī prospective randomized control trial (RCT) was conducted between April and October of 2016 after obtaining internal review board approval and patient consent. The purpose of this study was to assess the effectiveness and functional outcome of an app-based visual feedback rehabilitation program after total knee arthroplasty in a prospective randomized trial especially in long term. The ease of use can improve patients’ compliance, and encourage them to perform regular exercises at home. In the short term, functional outcome has been shown to be significantly better, although it needs additional instruction in the elderly population for proper use. The GenuSport mobile app was designed to be easy to use for improving postoperative quadriceps weakness and knee motion. This application allows for isokinetic exercises that can be otherwise very costly and time intensive. Since in-person sessions of physiotherapy are not always possible especially in the age of pandemic, a new application-based training device was invented and named GenuSport (GenuSport Knietrainer, Hannover Medical School, Germany). Mobile e-health app has also been shown to improve pain control and decrease opiate use in the initial postoperative period in some instances. Poorer stair climbing test result and slower timed 6-min walk can be observed in 90% of patients. In the first month after surgery, decrease in quadriceps muscle strength is observed in 60% of patients. This includes “enhanced recovery after surgery” (ERAS), which allows early mobilization on the same day of surgery as well as neuromuscular electrical stimulation (NMES). Ī major aspect of achieving functional outcome is the effectiveness of rehabilitation program, in addition to having appropriate anesthesia and sound surgical techniques. In long-term follow-up, excellent results with a small complication rate have been described. Total knee arthroplasty (TKA) is indicated for treatment of end-stage osteoarthritis, to improve pain, mobility and range of motion.
