Outcomes of total hip arthroplasty in calcium pyrophosphate deposition disease patients
Main finding · Mortality post-THAResult — go to the resultOdds ratio 0.35 95 % CI 0.26–0.47Authors' conclusion
CPPD patients who underwent THA were more likely to be older, with a greater comorbidity burden, longer LOS and discharged to a non-home setting.
