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.

Important patient characteristics differ prior to total knee arthroplasty and total hip arthroplasty between Switzerland and the United States.
The researchers compared preoperative patient and clinical characteristics from two large cohorts who underwent either total knee (TKA) or hip (THA) arthroplasty, one in Switzerland, the other in the US. They found substantial differences between US and Swiss cohorts in pre-operative patient characteristics and pain levels, which has potentially important implications for cross-cultural comparison of TKA/THA outcomes.

Preoperative pain and function: profiles of patients selected for total knee arthroplasty.
The researchers examined patient-reported preoperative pain and function profiles to understand symptom severity at the time of total knee arthroplasty (TKA) decision. Of 6,936 patients, 77 percent had high pain and poor function (group 4), 19 percent had high pain "or" poor function (groups 2-3), and 5 percent had little pain and high function before TKA (group 1).

KOOS pain as a marker for significant knee pain two and six years after primary ACL reconstruction: a Multicenter Orthopaedic Outcomes Network (MOON) prospective longitudinal cohort study.
The researchers applied three different models of Knee injury and Osteoarthritis Outcome Score (KOOS) thresholds for significant knee pain to an anterior cruciate ligament reconstruction (ACLR) cohort to identify prevalence and risk factors. They concluded that significant knee pain is prevalent after ACLR; with those who undergo subsequent ipsilateral surgery at greatest risk.
