Neighbors-based prediction of physical function after total knee arthroplasty.
The purpose of this study was to develop and test personalized predictions for functional recovery after Total Knee Arthroplasty (TKA) surgery, using a novel neighbors-based prediction approach. Findings showed that predictions were well-calibrated in out-of-sample testing. These predictions have the potential to inform care decisions both prior to and following TKA surgery.

Validation of an electronic coding algorithm to identify the primary indication of orthopedic surgeries from administrative data.
The purpose of this study was to develop and validate an algorithm to identify patients receiving four elective orthopedic surgeries to promote shared decision-making. The surgeries included were: 1) knee arthroplasty to treat knee osteoarthritis (KOA); 2) hip arthroplasty to treat hip osteoarthritis (HOA); 3) spinal surgery to treat lumbar spinal stenosis (SpS); and 4) spinal surgery to treat lumber herniated disc (HD). Electronic medical records were reviewed to ascertain a “gold standard” determination of the procedure and primary indication status. Each case had electronic algorithms consisting of ICD-10 and CPT codes for each combination and indication applied to their record. A total of 790 procedures were included in the study. The sensitivity of the algorithms ranged from 0.70 (HD) to 0.92 (KOA). Specificity ranged from 0.94 (SpS) to 0.99 (HOA, KOA).

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 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.

Risk of subsequent joint arthroplasty in contralateral or different joint after index shoulder, hip, or knee arthroplasty: association with index joint, demographics, and patient-specific factors.
The purpose of this study using HCUP data was to determine how demographic and other patient-specific factors are associated with the risk of subsequent joint replacement in the contralateral or a different joint following an index joint replacement for osteoarthritis. Results showed a relatively high risk of subsequent replacement of the contralateral joint and a relatively low risk of subsequent replacement of a different joint within 5 to 8 years after an index total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty. Obesity was associated with a higher risk of subsequent replacement of the contralateral joint or a different joint.
