MONDAY, April 4, 2022 (HealthDay News) — Hospital length of stay, complications, hospital readmission within 90 days, and revision surgery at two years do not differ for cementless total knee replacement (CL-TKR) versus cemented fixation (CEM) TKR, according to a study presented at the annual meeting of the American Academy of Orthopaedic Surgeons, held from March 22 to 26 in Chicago.<\/p>\n
Kyle Alpaugh, M.D., from Massachusetts General Hospital in Boston, and colleagues reviewed 598 primary unilateral TKRs (170 CL-TKRs and 428 CEM-TKRs) of the same design from 2016 to 2018 to examine early complications and treatment failure, defined as any reoperation.<\/p>\n
The researchers found that patients undergoing CL-TKR were younger and more often male. Computer assistance was used less frequently for CL-TKR. Less operative time was required for CL-TKR (82.6 \u00c2\u00b1 21.4 versus 109.1 \u00c2\u00b1 24.6 minutes), but the groups did not differ in terms of mean length of stay (57 versus 60.5 hours). Ninety-day readmission did not differ between CL-TKR and CEM-TKR (1.8 versus 0.9 percent). At two years, survivorship free from revision was 96 and 95 percent for CL-TKR and CEM-TKR, respectively. CL-TKR failure was 1 percent (two cases) due to aseptic loosening; both cases underwent isolated tibial component revision, with no additional complications.<\/p>\n
“The biggest question now is whether or not cementless total knee replacement will have better long-term durability and fixation than cemented knee replacement,” coauthor Brian P. Chalmers, M.D., of the Hospital for Special Surgery in New York City, said in a statement. “Following these patients to assess long-term outcomes is the next step.”<\/p>\n
