Suture anchors have been commercially developed to facilitate stable attachment of soft tissues to bone. Although their use is well characterized in orthopedic literature, suture anchors may also be of benefit in the reconstruction of large soft tissue defects by plastic surgeons. Suture anchors (Mitek Surgical Products, Inc., Westwood, MA) were used to fasten pedicled muscle flaps to exposed bone in 7 patients at Duke University undergoing reconstruction of large soft tissue defects. The suture anchor appeared to provide stability for the advancement flap, and there were no suspected postoperative muscle dehiscences or suture breakages. The suture anchor provides an easy, secure method to attach soft tissue to exposed bone, and preliminary experience appears to support their use in certain soft tissue reconstruction procedures by plastic surgeons. Suture anchors should be reserved for cases in which a large muscle flap is needed to cover exposed bone and poses a risk of shearing away from the bone, or adequate periosteum and soft tissue is not available for standard suture techniques.

Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
Purpose: Undifferentiated pleomorphic sarcomas (UPSs) demonstrate therapy-induced hemosiderin deposition, granulation tissue formation, fibrosis, and calcification. We aimed to determine the treatment-assessment value of morphologic tumoral hemorrhage patterns and first- and high-order radiomic features extracted from contrast-enhanced susceptibility-weighted imaging (CE-SWI).
Materials And Methods: This retrospective institutional review board-authorized study included 33 patients with extremity UPS with magnetic resonance imaging and resection performed from February 2021 to May 2023.

Background: Comorbidity indices are used to help to estimate patients' length of hospital stay, care costs, outcomes, and mortality. Increasingly, they are considered in reimbursement models. The applicability of comorbidity indices to patients undergoing orthopaedic oncology surgery has not been studied.

Owing to the high invasion depth and easy formation of biofilms, the treatment of subcutaneous fungal infection is intractable and challenging. Herein, we report an injectable and biodegradable hydrogel with bactericidal, quorum sensing inhibition and antioxidant activities for the in situ treatment of subcutaneous fungal infection. The hydrogel (BEPE) was constructed by irradiating mixed bovine serum albumin (BSA), ε-polylysine and epigallocatechin gallate (EGCG)-loaded mesoporous polydopamine (PDA) under near-infrared (NIR) light.

Purpose: Optimal management of retroperitoneal soft tissue sarcoma (RPS) often requires extensive tumor resections, frequently involving gastrointestinal organs. The impact of these procedures on the nutritional status and hemoglobin (Hb) levels of RPS patients remain unexplored. In this study, we aimed to evaluate preoperative nutritional status as well as the prevalence of anemia in RPS patients, and to investigate longitudinal changes throughout the disease course in order to identify potential strategies for prehabilitation.
