| Abstract | BACKGROUND: Risk stratification is critical in patients with cirrhosis undergoing THAs and TKAs, as they may be more likely to have serious medical and surgical complications. As opposed to the Child-Pugh scoring system, which has limited use for orthopaedic surgeons inexperienced in assessing ascites and hepatic encephalopathy, the Model for End-stage Liver Disease (MELD) is an easily calculated, validated scoring system for severity of liver disease based on common laboratory values; however, its usefulness for predicting complications after elective arthroplasty has not been studied. QUESTIONS/PURPOSES: The purposes of this study were to determine the differences between patients with cirrhosis and control subjects in (1) hospital length of stay, discharge disposition, and readmission within 90 days; (2) early postoperative (90 days) medical complications potentially related to liver disease; (3) surgical complications within 90 days and any time after the procedure; (4) mortality rates after THA and TKA; and in addition, (5) to use the MELD score as a predictor for risk of complications and mortality. METHODS: Institutional database query software used coding data identified 115 patients with liver cirrhosis before having THAs or TKAs from 2000 to 2012 and 115 control subjects without cirrhosis matched by age, sex, procedure, and year of surgery. Early postoperative and longer-term medical and surgical complications were compared. Regression analysis was used to determine a MELD score that predicted greater risk of complications. RESULTS: Compared with matched control subjects, patients with cirrhosis had prolonged length of stay and higher rates of discharge to nursing facilities, readmission in 90 days, and urinary tract infections (p < 0.01), renal failure (p = 0.03), blood transfusions (p < 0.01), gastrointestinal hemorrhage (p = 0.04), dislocations (p = 0.01), infections (p = 0.02), and revisions (p = 0.04) within 90 days. One-year (p = 0.01) and longer-term (p = 0.0002) mortality rates were greater in patients with cirrhosis. A MELD score of 10 or greater predicted a three times increased likelihood (odds ratio [OR]) of any complication (95% CI, 1.28-7.00; p = 0.01) and 4.1 times increased likelihood (OR) of death (95% CI, 1.42-11.86; p < 0.01). CONCLUSIONS: Patients with cirrhosis undergoing THAs and TKAs should be counseled regarding their increased risk of medical complications, surgical complications, and death. A MELD score of 10 or greater is associated with a high rate of complications, although this finding needs further validation because we were unable to control for all medical confounders. LEVEL OF EVIDENCE: Level III, prognostic study. See the Instructions for Authors for a complete description of levels of evidence. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
