When analyzing the extensive, long-term survivorship data of unicompartmental knee arthroplasty (UKA) compared to total knee arthroplasty (TKA) within major national joint registries, what is the consistently observed statistical reality regarding revision rates?
A
UKA consistently demonstrates a significantly lower overall revision rate than TKA.
B
UKA and TKA possess statistically identical 15-year survivorship profiles.
C
UKA has a much higher revision rate for deep infection but a lower rate for aseptic loosening.
D
UKA generally demonstrates a higher overall revision rate, heavily influenced by a lower threshold for surgeons to revise a partial knee.
