Functional gain and pain relief after total joint replacement according to obesity status.
The researchers examined the changes between preoperative and postoperative function and pain in a large representative U.S. cohort to determine if there was a relationship to obesity status. They found that six months after total joint replacement, severely or morbidly obese patients reported excellent pain relief and substantial functional gain that was similar to the findings in other patients.

Change in physical activity and sedentary time associated with 2-year weight loss in obese adults with osteoarthritis.
The investigators examined if changes in moderate-to-vigorous physical activity (MVPA), light activity, and sedentary behavior are related to weight change over a 2-year period in obese adults with elevated risk for knee osteoarthritis. They found that small increases in MVPA and decreases in sedentary time over 2 years were associated with weight loss among adults with obesity and with or at elevated risk for knee osteoarthritis.

Increasing obesity and comorbidity in patients undergoing primary total hip arthroplasty in the U.S.: a 13-year study of time trends.
The researchers examined the time-trends in key demographic and clinical characteristics of patients undergoing primary total hip arthroplasty (THA). They found that obesity, medical and psychological comorbidity increased and the underlying diagnosis of RA/inflammatory arthritis decreased rapidly in primary THA patients over 13-years.
