Tibial tunnel widening in patients undergoing primary anterior cruciate ligament reconstruction: hydroxyapatite-coated vs. uncoated interference screws.

Introduction: Tunnel widening following anterior cruciate ligament (ACL) reconstruction remains a significant clinical concern. Polyether ether ketone (PEEK) screws offer favorable biomechanical properties and MRI compatibility; however, they lack osteoconductivity, which may contribute to tunnel widening. This study investigated whether hydroxyapatite (HA)-coated polyether ether ketone (PEEK) screws reduce tibial tunnel widening compared to uncoated PEEK screws, considering the osteoconductive properties of HA.

Clinical and radiological outcomes of surgically treated medial malleolus fractures in skeletally immature patients.

Background: Medial distal tibial Salter-Harris Type 3 and Type 4 epiphyseal injuries, also known as McFarland fractures, pose significant risks due to their potential to damage the growth plate and cause long-term joint deformities. Surgical treatment is commonly performed to restore joint congruity; however, there is no clear consensus on whether surgical or conservative treatment yields better outcomes. This study aimed to evaluate the mid-term clinical and radiological outcomes of surgical treatment in patients with McFarland fractures.
