Multi-investigator collaboration in orthopedic surgery research compared to other medical fields: Update comparing 2021-2009.

The purpose of this study was to assess the prevalence of multicenter studies in the orthopedic literature compared to general medicine and other surgical subspecialty studies as an update to a previous study. The number of multicenter research studies across three orthopedic surgery journals was higher in 2021 compared to 2009 (7.2% [95% CI: 5.

Medial Patellofemoral Ligament Reconstruction in Obese Patients Results in Low Complication Rates and Improved Subjective Outcomes.

Purpose: To compare outcomes, activity scores, and complication rates of obese and non-obese patients undergoing medial patellofemoral ligament (MPFL) reconstruction.

Methods: A retrospective review identified patients undergoing MPFL reconstruction for recurrent patellofemoral instability. Patients were included if they had undergone MPFL reconstruction and had follow-up for a minimum of 6 months.

No Difference in Complication Rates or Patient-Reported Outcomes Between Bone-Patella Tendon-Bone and Quadriceps Tendon Autograft for Anterior Cruciate Ligament Reconstruction.

Purpose: To compare subjective outcomes and complications of anterior cruciate ligament reconstruction (ACLR) using either bone-patellar tendon-bone (BPTB) or quadriceps tendon (QT) autograft.

Methods: A retrospective analysis of prospectively collected data identified consecutive cohorts of patients undergoing ACLR with either BPTB or QT autograft. Patients with less than 12-month follow-up and those undergoing concomitant osteotomies, cartilage restoration, and/or other ligament reconstruction procedures were excluded.
