Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to estimate the effect of an application on rehabilitation for osteoarthritis patients after total knee arthroplasty.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Apart from surgical technique, the outcome of total knee arthroplasty (TKA) also largely depend on adequate rehabilitation and subsequent functional recovery after surgery.Rehabilitation affects or even determines various performance of post-operative knee, including knee range-of-motion (ROM), muscle strength, functional independence, all of which subsequently affect patients' quality of life. Conventional way of rehabilitation is exercise therapy, which rely on guidance of therapists and the self-efficacy of patients.

An application (APP) on smart phone was designed for people received TKA to play the role of guider and help improving patients' self-efficacy. This is a single-centre randomized clinical trial, with an anticipation of 200 patients with knee osteoarthritis enrolled, who will be randomly assigned into experiment group or control group. The patients in the experiment group will be introduced to this APP and requested to use it regularly, while the patients in the control group will receive pure conventional rehabilitation. Primary outcome includes Visual analogue scale (VAS) of pain, knee society score (KSS), ROM, ability of daily living (ADL) before operation and at 2 weeks and 6 weeks after surgery. All potential covariates of those two groups, such as age, sex, and pre-operative kellgren-lawrence scores would be matched by completely randomize.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Application Group

People in this arm will be introduced to an APP on smart phone, and receive lessons on how to use it on their own phones. The APP will be installed and prepare to use before surgery. People will be asked and monitored on-line to regularly use the APP.

Group Type EXPERIMENTAL

APP

Intervention Type OTHER

An APP designed for patients experienced TKA, including on-line lessons on the action, frequency, intensity of rehabilitation exercises, and reporting system monitored by stuff from surgery team.

Convention Group

People in this arm receive exactly the same treatment and lessons on post-operative rehabilitation except the reach of the APP.

Group Type NO_INTERVENTION

No interventions assigned to this group
