Similar outcomes found in cemented, cementless fixation for TKA
No statistically significant differences in clinical or radiologic outcomes were found between cemented and cementless tibial fixation, according to study results.
Researchers randomly assigned 126 patients undergoing primary total knee arthroplasty for degenerative osteoarthritis to receive either cemented or cementless tibial component fixation. Mean follow-up was 113.8 months in the cemented group and 114.9 months in the cementless group.
All patients underwent the same method of clinical and radiologic outcome assessment at 1 year and every year thereafter. At follow-up visits, the patients were asked to report on any complications or reoperations. Patients also underwent evaluation for range of motion, the Hospital for Special Surgery (HSS) Knee Score, WOMAC score, and Knee Society rating system with Knee Society Knee Score and Functional Score at each follow-up.
Results showed no significant differences in mean Knee Society Scores, HSS scores, mean WOMAC scores, mean ranges of knee movement or in radiological results between the two groups, according to the researchers. The researchers also identified no osteolysis in either group.
At final follow-up, both groups had 100% rate of survival of the femoral and tibial components, according to study results. – by Casey Tingle
