Arthroscopic Removal of Traumatic Fractures of the Proximal Medial Trochlear Ridge of the Talus: A Retrospective Analysis of 18 Horses.

Vet Comp Orthop Traumatol

January 2025

Donnington Grove Veterinary Surgery, Newbury, Berkshire, United Kingdom.

Objective:  The objectives of this study were (1) to evaluate the need for flexed radiographs of the proximal medial trochlear ridge (PMTR) after trauma involving medial tarsus; (2) to evaluate outcome following arthroscopic removal of traumatic osteochondral fragments (TOCF) resulting from direct injury to PMTR.

Methods:  Records of patients with wounds to the medial tarsus were searched and those with TOCF of the PMTR included. Patient history, fracture etiology, preoperative diagnostics, and intraoperative findings were documented.

Background: Limitations to using the knee as donor cartilage include cartilage thickness mismatch and donor site morbidity. Using the radial head as donor autograft for capitellar lesions may allow for local graft harvest without distant donor site morbidity. The purpose of this study is to demonstrate the feasibility of performing local osteochondral autograft transfer from the nonarticular cartilaginous rim of the radial head to the capitellum.
