Arthropathy of Knee, Joint Awareness, Osteoarthritis, Knee
Conditions
Brief summary
Comparison of postoperative patient's joint awareness as well as clinical and radiological outcomes between fixed- and mobile-bearing total knee arthroplasty of which the prosthesis is coated with Titanium-nitride.
Detailed description
Despite numerous comparison studies between mobile- and fixed-bearing TKA as well as several comparison studies regarding clinical and radiological outcomes using titanium-nitride(TiN) prosthesis, there has been no study on postoperative joint awareness despite mobile- and fixed-bearing TKA using TiN prosthesis.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Forgotten joint score | Postoperative 3 years | Questionnaire of evaluating how much the patients are aware of their operate joint during daily activities. The higher, the worse. Range: 0-100 |
| Crepitus | Postoperative 3 years | Any grating, crackling or popping sensation around knee when moving a joint |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Forgotten joint score | Postoperative 5 years | Questionnaire of evaluating how much the patients are aware of their operate joint during daily activities. The higher, the worse. Range: 0-100 |
| Crepitus | Postoperative 5 years | Any grating, crackling or popping sensation around knee when moving a joint |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline Knee Society Score (KSS) at 3 and 5 years | Preoperative and Postoperative 3, 5 years | Patient-reported Outcome measure; The lower, the worse. Range: 0-200 |
| Change from baseline Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 3 and 5 years | Preoperative and Postoperative 3, 5 years | Patient-reported Outcome measure; The higher, the worse. Range: 0-96 |
| Central Sensitization Index (CSI) | Postoperative 3 years | Questionnaire of evaluating how much the patients are sensitized on the pain. The higher, the worse. Range: 0-100 |
| Radiological outcomes | Postoperative 3 years | Measurements of radiological angles |
