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.
