Fixed-bearing versus high-flexion RP total knee arthroplasty (TKA): midterm results of a randomized controlled trial
1Department of Orthopaedic Surgery, Military Hospital Kirkee, Pune, Maharashtra, 20, India. amit3460@gmail.com.
Background:
We compared the midterm results after total knee arthroplasty (TKA) using PFC Sigma RP-F mobile model with PFC Sigma PS fixed model.
Materials And Methods:
In this randomized controlled trial, we analyzed 50 knees that underwent TKA with PFC Sigma RP-F and 60 knees with PFC Sigma PS fixed model. The follow-up period ranged from 76 to 104 months.
Results:
The knee score, function score, and radiographic evaluation were significantly not different between the two groups at final follow-up. No revisions, subluxations, dislocations, or infections were seen. Also, no radiographic evidence of component loosening, osteolysis, or malalignment was observed in any knee. The results for both groups show good patient satisfaction.
Conclusions:
The midterm clinical and radiographic results of the two prostheses did not show significant differences between the two groups.
Level Of Evidence:
Level of evidence is level II.
