Objective: To report arthroscopic osteochondral fragment removal from the equine cervical spine articular process joints (APJs) including long-term follow-up.
Study Design: Case series.
Animals: Three Warmblood horses with forelimb lameness and/or reduced range of motion of the cervical spine with osteochondral fragments between the cervical vertebrae C /C or C /C .
Method: Arthroscopy of the APJs of C /C and C /C was performed under general anesthesia. Following endoscopic evaluation of the joints, osteochondral fragments were removed using a rongeur.
Results: All horses recovered from anesthesia with no anesthetic or minor postanesthetic complications. One horse needed a second procedure for fragment removal. Fourteen to 31 months post-surgery the horses were sound for their intended use and neurological examination revealed no abnormalities.
Conclusion: Arthroscopic removal of osteochondral fragments can be performed safely in the equine cervical APJs of C /C and C /C resulting in a favorable long-term outcome.
Clinical Significance: Arthroscopic removal is a valid option for horses showing clinical signs that can be attributed to osteochondral fragments in the APJs of the neck.

Osteochondral injuries in the knee are uncommon in the immature skeleton and are usually related to sporting activities. Fixation is required depending on the size and location of the fragment. The standard technique is open reduction and internal fixation with metal screws, which are removed in a second procedure after consolidation.

Background: Postoperative osteolysis may be observed around poly-l-lactic acid (PLLA) pins in osteochondral fragments fixation for an osteochondral lesion of the talus (OLT). Hydroxyapatite (HA) improves biocompatibility, osteoconductivity, and mechanical strength when added to PLLA. This study aimed to compare the characteristics of osteolysis and clinical outcomes of fixation for OLT with PLLA pins vs PLLA/HA pins.

Introduction: Management of osteochondritis dissecans (OCD) lesions of the capitellum is challenging. Historically, variability exists between surgeons in the evaluation, treatment, and return to sport criteria. The purpose of this study was to define the current trends regarding evaluation, nonoperative and surgical management, and return to sport criteria for capitellar OCD lesions among surgeons.

Purpose: To explore the efficacy and feasibility of arthroscopy combined with bone tunnel technique in treating Berndt and Harty stage III or IV osteochondral lesions of the talus (OLT).
Methods: A retrospective analysis was conducted on the clinical data of 21 patients with Berndt and Harty stage III or IV OLT who underwent surgical treatment at our institution from September 2017 to September 2022. Under arthroscopy, the displaced talar osteochondral lesion was restored.
