Background: The purpose of this individual cohort study is to demonstrate safety and efficacy in removing the trapezium through minimally invasive arthroscopy.
Methods: A prospective case series was performed on all arthroscopic total trapeziectomy procedures for thumb basal joint arthrosis between 2018 and 2022. Patients were followed for up to 1 year. All patients received an examination at each visit to include pain, range of motion, strength, and metacarpal height. Complications, concomitant procedures, and revision procedures were recorded as well.
Results: A total of 49 arthroscopic trapeziectomy procedures were recorded for 46 patients. The average preoperative visual analog pain scale score was 8.8 out of 10, and the postoperative score was 1 out of 10. All patients had a resolution of the carpometacarpal grind test postoperatively. The average preoperative key pinch, 3-point chuck, and grip strength were 9.8 lbs/in, 7.8 lbs/in, and 45 lbs/in, respectively. Final 6-month postoperative key pinch, 3-point chuck, and grip strength were 11.0 lbs/in, 9.8 lbs/in, and 49.2 lbs/in, respectively. Metacarpal height subsided on average 50%. We report one revision and no cases of radial sensory neuritis or flexor tendon rupture.
Conclusions: Arthroscopic total trapeziectomy appears to be a safe and effective treatment for end-stage arthrosis of the thumb basal joint.

Background: Interest in biological augmentation for improving bone-tendon interface (BTI) healing after arthroscopic rotator cuff repair (ARCR) is growing. Dermal fibroblasts, known for collagen synthesis similar to tenocytes, have shown effectiveness in BTI healing in chronic rotator cuff tear (RCT) models in rabbits. However, no human clinical trials have been conducted.

Background Deep learning (DL) methods can improve accelerated MRI but require validation against an independent reference standard to ensure robustness and accuracy. Purpose To validate the diagnostic performance of twofold-simultaneous-multislice (SMSx2) twofold-parallel-imaging (PIx2)-accelerated DL superresolution MRI in the knee against conventional SMSx2-PIx2-accelerated MRI using arthroscopy as the reference standard. Materials and Methods Adults with painful knee conditions were prospectively enrolled from December 2021 to October 2022.
