Enhancing Rotator Cuff Repair in Rabbit Osteoporosis With Chitosan Quaternary Ammonium Salt-Coated Nickel-Titanium Memory Alloy Anchors.
Am J Sports Med
January 2025
Department of Orthopaedics, Lanzhou University Second Hospital, Lanzhou, Gansu, P.R. China.
Background: For patients with osteoporosis and rotator cuff tears, there is still no consensus on current treatment methods. The material, structure, and number of anchors have important effects on the repair outcome.
Purpose: To investigate the use of chitosan quaternary ammonium salt-coated nickel-titanium memory alloy (NTMA) anchors to treat rotator cuff injury in shoulders with osteoporosis in a rabbit osteoporosis model.
Functional Outcomes of Nuts-in-Jelly Mosaicplasty.

Ortho One Orthopaedic Specialty Centre, Coimbatore, India.
Introduction: Interspace defects after osteochondral autograft transfer (OATS) are filled only with fibrocartilage. Attempts have been made to address these issues in OATS with procedures like mega OATS and Hexagonal Osteochondral Graft System. We have described the functional outcomes of a hybrid technique combining a regeneration and a restoration modality to address the interspace defect in OATS.

Purpose: To investigate the effect of concomitant chronic lateral ankle instability (CLAI) on postoperative clinical outcomes in patients with osteochondral lesions of the talus (OLTs).
Methods: Patients who underwent surgery for OLTs between January 2018 and May 2022 were retrospectively evaluated. OLT procedures involved debridement, microfracture, or bone grafting, while concomitant CLAI underwent lateral ligament repair or reconstruction.
All Arthroscopic Osteochondral Autograft Transplantation for Medial Talar Dome Lesions Talus With Burring of the Anterior Lip of the Distal Tibia.

Orthopaedic Department, Faculty of Medicine in Assiut, Al-Azhar University, Cairo, Egypt.
Osteochondral lesions of the talus are chondral lesions affecting the subchondral bone mostly due to acute ankle trauma, including either sprains or fractures. After failure of conservative treatment, operative treatment is necessary, with different surgical techniques described in the literature. We describe a single-step osteochondral autograft transfer to access the medial talar dome lesion that avoids the need for a medial malleolar osteotomy and therefore eliminates morbidity while reducing operative time.

The present study evaluated the clinical outcomes and satisfaction of patients undergoing fresh homologous osteochondral transplantation in the knee as a salvage method. We analyzed eight knees from seven male patients who underwent fresh homologous osteochondral transplantation by a single surgeon. Their follow-up period ranged from 10 months to 5 years and 5 months.
