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.

Retroperitoneal versus transperitoneal approach for open repair of complex abdominal aortic aneurysms.
This retrospective analysis compared the outcomes of a transperitoneal approach (TP) versus the retroperitoneal approach (RP) for infrarenal abdominal aortic aneurysm (AAA) repair. Several studies have found an advantage for the RP approach. Among a cohort of 1,195 patients identified 729 (61%) underwent cAAA repair via a TP approach and 39% via an RP approach. After adjustment, the RP approach was associated with lower odds of peri-operative death (4.0% versus 7.2%) and lower odds of any major, cardiac, or wound complications and post-operative sepsis. Despite this, the proportion of repairs using an RP approach decreased between 2011 to 2015 and 2016 to 2019.

Reevaluating the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer.
This study reevaluated the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer. The authors looked at the FACS, GILDA, and COLOFOL trials and used a model to predict the large-sample mortality reduction expected for each trial and the implied statistical power. An investigation was done of a potential recurrence imbalance in the FACS trial. The model predicted a mortality reduction of ≤5% and power of <10% for all 3 trials. The FACS recurrence imbalance most likely led to a large relative bias (>2.5) in the hazard ratio for overall survival favoring control. After adjustment, both COLOFOL and FACS results were consistent with model predictions. A 2.6 and 3.6 month increase in life expectancy is predicted comparing intensive extracolonic surveillance-routine computed tomography scans and carcinoembryonic antigen assays with 1 computed tomography scan at 12 months or no surveillance, respectively. A larger trial that would randomize at least 200 to 300 patients is needed, but is not feasible at this time. The authors concluded recent trial results do not warrant de novo skepticism or metastasectomy nor targeted extracolonic surveillance.
