Age-related differences in pain, function, and quality of life following primary total knee arthroplasty: results from a FORCE-TJR (Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement) cohort.
The purpose of this prospective, multicenter cohort study was to evaluate the differences in pain, function, and quality of life (QoL) reported 1 year after total knee arthroplasty (TKA) across varying age groups. The researchers preoperatively assessed 11,602 unilateral primary TKA patients, and collected demographic data, comorbid conditions, and patient-reported outcome measures including the knee injury and osteoarthritis outcome score (KOOS), KOOS-12, KOOS Joint Replacement, and Short-Form health survey (12-item) and then collected again at 1-year postoperatively. The study found that prior to surgery, patients less than 55 years reported worse KOOS pain (39), function (50), and QoL (18) scores with poor mental health score (47) than other older patient groups. At 1 year after TKA, patients less than 55 years reported lower KOOS pain, function, and QoL scores when compared to patients 75 years or older. The differences in score changes among the age groups were statistically significant but clinically irrelevant. Further statistical analyses revealed that age was a significant predictor for pain, but not for function at 1 year where KOOS pain score was predicted to be higher in patients 75 years or older when compared to patients less than 55 years of age.

Patient-reported outcomes following cemented versus cementless primary total knee arthroplasty: a comparative analysis based on propensity score matching.
The purpose of this study was to compare baseline and early post-operative global and condition-specific patient reported outcomes (PROs) between patients undergoing cemented versus cementless total knee arthroplasty (TKA). The researchers prospectively collected PROs through the Comparative Effectiveness Pulmonary Embolism Prevention After Hip and Knee Replacement (PEPPER) trial using the short-form of the Knee Injury and Osteoarthritis Outcome Score (KOOS-Jr.), the Patient-Reported Outcomes Measurement Information System Physical Health (PROMIS-PH), and the Numeric Pain Rating Scale (NPRS). Pre- and post-operative outcomes in 5,961 patients undergoing primary TKA between December 2016 and August 2021 were examined. The study found that significant pre to- post-operative were observed in both groups. The researchers concluded that patients with cemented TKA reported early benefit in KOOS-Jr. over those with cementless TKA.

Comparing "people-like-me" and linear mixed model predictions of functional recovery following knee arthroplasty.
This study compared the relative strengths and weaknesses of 2 prediction model approaches for predicting functional recovery after knee arthroplasty: a neighbors-based "people-like-me" (PLM) approach and a linear mixed model (LMM) approach. The authors used 2 distinct datasets to train and then test PLM and LMM prediction approaches. They used the Timed Up and Go (TUG)-a common test of mobility-to operationalize physical function. Both approaches use patient characteristics and baseline postoperative TUG values to predict TUG recovery from days 1-425 following surgery. They then compared the accuracy and precision of the two approaches. A total of 317 patient records with 1379 TUG observations were used to train approaches, and 456 patient records with 1244 TUG observations were used to test the predictions. Both approaches performed similarly in terms of mean squared error and bias, but the PLM approach provided more accurate and precise estimates of prediction uncertainty.

Examination of exclusion criteria in total knee arthroplasty rehabilitation trials: influence on the application of evidence in day-to-day practice.
This study investigated whether total knee arthroplasty (TKA) patients seen in routine practice who meet common exclusion criteria in clinical trials recover differently compared to research-eligible patients. Postoperative functional outcomes were compared using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Timed Up and Go (TUG). A total of 2,528 participants from 27 trials were compared to 474 patients from the clinical dataset. Research participants were older, with lower BMI than patients in the clinical dataset. There were no differences observed in functional recovery rate between groups, except for patients with diabetes whose TUG recovered more slowly than “eligible” patients.

Associations between comorbidity and quality of life outcomes after total joint replacement.
In this study, a cross-sectional, questionnaire-based national survey, the authors examined associations between self-reported and clinician-assessed comorbidity and quality of life (QOL) outcomes after hip and knee replacement. The investigators concluded that the results showed that general QOL outcomes following hip and knee joint replacement, while typically high, were associated with comorbidity burden and BMI.

Effect of outpatient rehabilitation on functional mobility after single total knee arthroplasty: a randomized clinical trial.
Researchers compared post-total knee arthroplasty (TKA) functional mobility outcomes among 3 newly-developed physical therapy protocols with a standard-of-care post-TKA rehabilitation protocol. They found no statistically or clinically significant differences in outcomes across the 4 study arms (control, treadmill, neuromuscular stimulation device, and combination intervention). As outcomes were similar among arms, they recommended that clinicians instead consider relative cost in tailoring TKA rehabilitation.

What outcomes matter to patients after joint or spine surgery?
In this study, semi-structured interviews were conducted with 65 patients undergoing hip or knee replacement, spinal discectomy/laminectomy, or a spinal fusion to examine what patient-reported outcome measures (PROMs) patients identified as most important. The investigators found that patients identified specific preferred outcomes from these surgical procedures that were important and meaningful to them and that framed whether they saw their surgery as a success. They also identified personal factors that they assumed their surgeons knew about, which affected their care and recovery.

Patient outcomes following total joint replacement surgery: a comparison of hospitals and ambulatory surgery centers.
This study used a large claims database of non-Medicare patients to examine inpatient and outpatient total knee replacement and total hip replacement surgery performed on a near-elderly population during 2014-2016. Findings support the argument that outpatient total joint replacement is appropriate for select patients treated in both hospital outpatient departments and ambulatory surgery centers, although in the commercially insured population, the latter services may come at a cost. Until further study of outpatient total joint replacement in the Medicare population becomes available, how this will extrapolate to the Medicare population is unknown.

Using cluster analysis to identify patient factors linked to differential functional gains after total knee arthroplasty.
This study used cluster analysis to identify patient factors linked to different outcomes following total knee arthroplasty (TKA). The study analyzed Short Form 36 Physical Component Score (PCS) trajectories of 656 patients at 3 time points over a 1-year period. The MultiExperiment View (MeV) built-in bootstrapping method was used to assess statistical significance of the clusters. They found two distinct clusters: Cluster 1 included 550 patients (84%) who demonstrated persistent improvement at 6 and 12 months. The remainder of patients consisted of Cluster 2 who demonstrated decline in PCS at 6 months but improved by 12 months. Cluster 1 was found to have higher baseline mental health scores, lower baseline PCS, and a significantly higher proportion of non-Hispanic Whites compared to Cluster 2.

Association of early postoperative pain trajectories with longer-term pain outcome after primary total knee arthroplasty.
Studies to date have not comprehensively examined pain experience after total knee arthroplasty (TKA). Discrete patterns of pain in this period might be associated with pain outcomes at 6 to 12 months after TKA. The purpose of this study was to examine patterns of individual post-TKA pain trajectories and to assess their independent associations with longer-term pain outcome after TKA.

Association of preoperative opioid use with mortality and short-term safety outcomes after total knee replacement.
The purpose of this study was to determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement (TKR). Findings show that continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. Highlights include the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

Improvement in mental health following total hip arthroplasty: the role of pain and function.
This prospective study examined whether mental health improved in patients who had total hip arthroplasty (THA) due to improvement in pain and function 1 year post-surgery. Patients enrolled in a THA registry from 2010 to 2014 were included and the mental component score (MCS) was examined before and 1 year post-surgery. There was a significant improvement in mental health due to less pain and improved function.

Comparison of a Patient-Centered Weight Loss Program starting before versus after knee replacement: a pilot study.
This article reports the results of a randomized pilot study that assessed changes in weight during a Patient Centered Weight Loss Program (PACE) initiated either before or after knee replacement. The feasibility of recruiting and retaining participants over 26 weeks was also examined. Recruitment outreach was extended to patients scheduled for knee replacement. Sixteen participants were randomly assigned to a 14-session weight loss program that started either at least 6 weeks before surgery or at 12 weeks following surgery. The authors conclude that behavioral intervention is challenging but feasible in a knee replacement population. Preliminary evidence suggests that initiating a program 12 weeks after surgery produces greater weight losses at 26 weeks when compared to a program that begins before knee replacement.

Use of patient-reported outcomes and satisfaction for quality assessments.
This study investigated the relationship between PROs and satisfaction among spine surgery patients. The authors hypothesized that there would be significant disparities between patient satisfaction and PROs at the 1-year postoperative time point. The study found that overall, patients undergoing elective lumbar spine surgery reported being satisfied with outcomes, but the reported responses in PROs were much more variable.
