Results from this study demonstrated women, patients 70 years and older, obese patients, those with diabetes, depression disorders and rheumatoid arthritis had a higher chance of conversion to total knee arthroplasty 2 years following a knee arthroscopy.
Researchers identified 68,090 patients older than 50 years who had a knee arthroscopy for either partial meniscectomy, chondroplasty or debridement between 1998 and 2014. Investigators stratified patients who underwent total knee arthroplasty (TKA) at 1 year, 2 years or 3 years following knee arthroscopy. Patient age, race, sex, obesity, diabetes, nicotine dependence, depressive disorder and rheumatoid arthritis were among the risk factors analyzed.
Findings showed at 1 year, 2 years and 3 years, the TKA incidence was 10.1%, 13.7% and 15.6%, respectively. Investigators noted factors associated with a higher risk of conversion to TKA at 2 years included obesity, depressive disorders, rheumatoid arthritis, women, age 70 years and older, and diabetes. Patients who were aged 50 years to 54 years had the lowest chance for TKA conversion. Men had a lower risk of conversion to TKA compared with women.
When obesity was combined individually with the top risk factors for conversion to TKA, investigators found no combination had a higher relative risk compared to obesity alone. by Monica Jaramillo
