The Outcomes of Subject After Total Knee Arthroplasty

Study Overview
=================
Brief Summary
-----------------
Total Knee Arthroplasty (TKA) is a standard of intervention for severe knee osteoarthritis, also been proven with benefits in improving pain, mobility, and quality of life. However, the outcomes after TKA is controversial.

Detailed Description
-----------------
Total Knee Arthroplasty (TKA) clinical pathway provides preoperative education, postoperative rehabilitation, and routine outpatient follow-up. The overall functional performance of the patient was assessed. The aim of this study was to analyze (1) clinical pain relief, anxiety reduction and functional recovery after TKA; (2) factors affecting individual functional recovery, such as age, gender, BMI, etc. The results can be used as a reference for improving the quality in TKA patients.

| --- | --- | --- |
| Changes of Western Ontario and McMaster Universities Arthritis Index (WOMAC) | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: (I). Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright (II). Stiffness (2 items): after first waking and later in the day (III).

The assessment was performed at: Baseline: admission date of surgery, discharge from hospital (D/C), 1 month after D/C, 3 months after D/C, 6 months after D/C | Baseline: date of surgery (day 0); discharge from hospital (D/C), an average of 1 week; 1 month after D/C; 3 months after D/C; 6 months after D/C | 
| Changes of knee Range of motion (ROM) | Range of motion in bilateral Knee joints | Baseline: date of surgery (day 0); discharge from hospital (D/C), an average of 1 week; 1 month after D/C; 3 months after D/C; 6 months after D/C |
