Background: Limited options exist for young patients with massive, irreparable rotator cuff tears. While several treatment exist, superior capsular reconstruction (SCR) was developed to restore glenohumeral joint stability by preventing humeral head migration during motion. Indications: Arthroscopic SCR is indicated in a tear. Patients require functioning deltoid muscle minimal no arthritis. In addition, should have Hamada grade 2 or less and an intact repairable subscapularis tendon....

Background: Total knee arthroplasty (TKA) demonstrates excellent durability using jig-based manual techniques (manual TKA [mTKA]), but significant rates of dissatisfaction remain. Modifications mTKA and implant designs to improve outcomes have had minimal success. Studies comparing relative robotic-assisted (raTKA) are limited. Purpose: This study sought compare raTKA in patients at a single institution. Methods: We retrospectively reviewed all primary TKAs performed by 1 surgeon from 2015...

Background: Multiple rehabilitation protocols after shoulder surgery have been proposed. The coronavirus pandemic adds an extra layer of complexity to postoperative surgery. Hypothesis: combined use a home-based system, the Shoulder Strengthening and Stabilization System (SSS), telehealth visits will lead acceptable patient self-reported outcomes satisfaction Study Design: Prospective observational cohort. Level Evidence: 4. Methods: A total 132 patients were prescribed SSS virtual clinical...

Purpose The aim of this study was to determine the comparative accuracy and precision routine Magnetic Resonance Imaging (MRI) versus MR arthrogram in measuring labral tear size as a function time from shoulder dislocation. Methods We retrospectively evaluated consecutive patients who underwent primary arthroscopic stabilization between 2012 2021 single academic center. All completed pre-operative MRI or within 60 days injury, subsequently repair 6 months imaging. Intraoperative location...

Peripheral nerve blocks are commonly used in total knee arthroplasty (TKA). Liposomal bupivacaine is an extended-release anesthetic medication that maintains efficacy upwards of 72 hours. This study compared single-shot liposomal (LB) with the standard (SB) a preoperative adductor canal block TKA patients. A double-blind randomized, controlled trial at single institution was performed patients undergoing TKA. injection 31 using 266 mg (20 mL), whereas 32 received formulation 0.5% hydrogen...

To evaluate factors associated with postoperative anterior shoulder pain following arthroscopic suprapectoral biceps tenodesis (ABT) and to determine the clinical impact of pain.A retrospective study patients that underwent ABT between 2016 2020 was conducted. Groups were categorized by presence (ASP+) or absence (ASP-) pain. Patient-reported outcomes (American Shoulder Elbow score [ASES], visual analog scale [VAS] for pain, subjective value [SSV]), strength, range motion, complication rates...
