Evaluation of a cranial arthroscopic approach to the stifle joint for the treatment of femorotibial joint disease in horses: 23 cases (1998-1999).

This research describes a surgical treatment approach to the stifle joint in horses dealing with femorotibial joint diseases. The success of the approach was assessed in 23 horses and found to be generally effective with some noted limitations.

Research Methodology

• The researchers conducted a retrospective study on the medical records of 23 adult horses.
• This study focused on the treatment of femorotibial joint disease, a common issue in horses that affects their mobility and performance.
• The researchers used a single-portal cranial arthroscopic approach to access and treat the stifle joint. This involved using the femoropatellar joint as the point of access, which allows for controlled access and reduced risk of damage to articular structures.

Findings of the Research

• Twenty-nine stifle joints of 23 horses were examined and treated using this approach.
• The majority of the conditions treated were subchondral bone cysts, which were found in 12 of the 23 horses. Unilateral cruciate ligament desmitis, meniscal tearing, or a combination of both were found in 9 horses. Only 2 horses had evidence of degenerative joint disease without cystic lesions or soft tissue trauma.
• Out of the 21 horses for which outcome data was collected, the treatment was considered successful in 15 cases. Success was defined as the horse returning to a level of performance equal to or better than what they were at prior to injury and lameness.
• For specific conditions, the success rate varied. Eight of the 12 horses treated for medial femoral condylar cysts had successful outcomes, while all four horses treated for cruciate ligament lesions returned to showing activity. However, none of the three horses with meniscal tearing were able to perform successfully post-treatment.

Conclusions of the Research

• The study concluded that the femorotibial joint could be effectively evaluated and treated through a single-portal cranial arthroscopic approach.
• This technique was found to be straightforward to perform and allowed for controlled access to the femorotibial joint, which reduced the risk of accidental damage to articular structures.
• It also required fewer access portals, providing an advantage over other techniques.
• While generally successful, the technique showed variable effectiveness depending on the specific condition being treated.
