Midterm clinical results of bi-cruciate stabilized total knee arthroplasty compared with posterior stabilized total knee arthroplasty with single radius design
Purpose
Attempts have been made to enhance knee prostheses design to improve clinical outcomes including bi-cruciate stabilized (BCS) TKA design and single-radius (SR) femoral component design. The complication rate of first generation BCS (fBCS) TKA was higher than that of standard TKA. Regarding BCS TKA, modification of the fBCS TKA system to the second-generation BCS (sBCS) TKA system was performed to avoid complications. This study aimed to compare the midterm clinical results of sBCS TKA and SR TKA.
Methods
We retrospectively reviewed data from TKA patients. A total of 142 patients who were followed up for at least 5 years were enrolled: 61 TKAs using sBCS and 81 TKAs using the posterior stabilized (PS) single-radius (SR) design. The clinical results at 6 months, 2 years, and 5 years postoperatively were compared between the sBCS and SR PS groups.
Results
At 6 months postoperatively, the maximum flexion angle (MFA) of the sBCS group was larger than that of the SR PS group. At 2 years, MFA, KOOS subscales of pain and ADL in the sBCS group were better and at 5 years, the MFA, KOOS subscales of pain and QOL in the sBCS group were better than those in the SR group. There was no significant differences of the ratios of complications and revision surgeries between the two groups.
Conclusion
The midterm clinical results of sBCS TKA were better than those of SR PS TKA in terms of the MFA and KOOS subscales of pain and QOL.
