Brief Summary:

Rehabilitation after total knee arthroplasty is very important in terms of range of motion of the knee, muscle power, normal gait, pain control and consequently the patient's satisfaction. Convectional rehabilitation methods in assist of therapist required high demand of resources. Recently, outpatient clinic or tele-communication tool based rehabilitations were investigated and reported equivalent results. However, those methods also required group or one-to-one facing that restricted availability of the exercise.

With development of the motion tracking technology, new device that gives real time feedback with augmented reality images can be used for rehabilitation in home-based setting.

This study aims to compare the clinical outcomes after the rehabilitation by interactive home-based device or conventional inpatient setting.

Condition or disease Intervention/treatment Phase
Osteoarthritis, Knee Arthroplasty Rehabilitation Device: Home Rehabilitation using Interactive device Other: Inpatient Rehabilitation Not Applicable

Detailed Description:

The objective of this work is to compare the pain, stiffness, function and satisfaction between groups at 6 months after the total knee arthroplasty.

The investigators hypothesized that the clinical outcomes of rehabilitation by interactive home-based device are not inferior than that by conventional inpatient setting.

The study design is a single-blind non-randomized controlled trial. Patients takes different rehabilitation method but the outcome assessor is blinded. The clinical outcome is compared at preoperative, postoperative 6weeks, 3months. And clinical outcome consists of Range of Motion (ROM), WOMAC (Western Ontario and McMaster University Arthritis Index ) score, Knee Society Score, Time-up-go (TUG) test.

Arm Intervention/treatment
Experimental: Interactive Device Rehabilitation Device: Home Rehabilitation using Interactive device
Rehabilitation is performed using interactive motion tracking augmented reality device. 6 exercises are included in one-day rehabilitation program. Each exercise is recorded in aspect of compliance, completion.

Active Comparator: Inpatient Rehabilitation Other: Inpatient Rehabilitation
Patients are given the exercises in the setting of inpatient rehabilitation

Primary Outcome Measures :
  1. Change in Western Ontario and McMaster Universities Index(WOMAC index) [ Time Frame: preoperative, postoperative at 6, 12 weeks ]
  2. Change in Knee Society Score [ Time Frame: preoperative, postoperative at 6, 12 weeks ]
  3. Change in Time-Up-Go (TUG) test [ Time Frame: preoperative, postoperative at 6, 12 weeks ]
