ABSTRACT
Aims: This study aims to evaluate the outcomes of knee arthroplasty for the treatment of severe osteoarthritis in 7A Military Hospital
from Jun 2016 to Jun 2019. Methods: This study used a cross-sectional descriptive approach and made an investigation on 78
patients treated with total knee arthroplasty using Triathlon (Stryker) prosthetic knee in 7A Military Hospital from Jun 2016 to Jun
2019. Results: The maximum, minimum, and average ages of the patients were 95, 53, and 64.8 (11.3) years, respectively. There were
20 males (25.6%) and 58 females (74.4%) patients. Thirty-four patients had left knee arthroplasty, and forty-four had right knee
arthroplasty. The average hospital stay-in was 9.8 (2.8) days, and the average monitor time was 17.2 (0.8) months. The average Knee
Score was 59.6 (10.1) preoperatively and 89.2 (11.6) postoperatively; the difference was significant (p < 0.05). Average Knee Function
Score was 33.5 (4.9) preoperatively and 79.3 (6.1), the difference was significant (p < 0.05). The average knee bending angle was
106.7° (16.2°). Pleasant of treatment outcome was achieved in 79.5% cases. Discussion: The results showed a definite improvement of
knee conditions and functional movement, and the patient’s responses were generally satisfactory, which was compatible with other
literature reports. Conclusion: Knee arthroplasty is an effective treatment for severe cases of osteoarthritis; it relieves the pain,
improves joint movement and ambulation, and increases life quality for the treated patients.
