Background: Knee osteoarthritis (OA) is a progressive degenerative joint disease characterized by cartilage degradation and osteophyte formation, leading to chronic pain, reduced mobility, and significant impairment in daily activities. As a primary weight-bearing joint, the knee is particularly susceptible to OA, making it one of the leading causes of disability worldwide.
Methodology: This multicenter clinical study enrolled 150 patients, evaluating a total of 216 knees that underwent total knee arthroplasty (TKA) using the EMPK (EXCEL MEDIAL PIVOTAL KNEE SYSTEM) prosthesis. Clinical outcomes were assessed using validated patient-reported outcome measures (PROMs), including the Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Oxford Knee Score (OKS), both preoperatively and at three months postoperatively.
Results: The study cohort had a mean age of 65.7 ± 7.19 years, with a higher proportion of women patients. At three months postoperatively, the mean OKS increased significantly from 13.4 ± 3.5 preoperatively to 26.7 ± 4.2 (p < 0>
Conclusion: The EMPK prosthesis demonstrated significant short-term improvements in knee function, pain relief, and overall quality of life in patients with end-stage knee osteoarthritis. These findings are consistent with existing literature on contemporary TKA systems, reinforcing the efficacy of EMPK as a reliable surgical option. However, ensuring optimal postoperative management, including infection control and implant longevity strategies, remains critical for sustaining long-term clinical benefits.
