Introduction:

Total Knee Arthroplasty (TKA) is one of the most frequently performed orthopedic interventions worldwide, with more than 700,000 primary procedures conducted in 2013. This study aims to demonstrate that TKA with cemented components and mobile bearings is a solid treatment option with low complication rates, good clinical outcomes, and adequate long-term survival.

Materials and methods:

this retrospective study included 890 cases in 810 patients diagnosed with grade IV gonarthrosis, with a mean age of 67.80 years and a mean follow-up period of 12.5 years. Joint replacement was performed using the Langenbeck approach. Evaluation was both radiological and functional, using the American Knee Society Score (AKSS) and Oxford Knee Score (OKS) scales to demonstrate long-term results.

Results:

the preoperative clinical AKSS was 58.7, and 94.4 points at 14 years; the preoperative functional AKSS was 56.73, and 72.5 points at 14 years; and the preoperative OKS was 26.77, and 44.2 points at 14 years, with a cumulative survival rate of 98.0% at 14 years, using revision for any reason as the primary endpoint.

Conclusion:

TKA with mobile bearings for the treatment of grade IV gonarthrosis shows favorable functional outcomes, high long-term survival rates, and low complication rates.
