Summary
Osteochondritis dissecans (OCD) in cats can cause hind limb lameness. Surgical removal of the cartilage flap and bone curettage effectively treated OCD in both stifles of a young cat.
Area of Science:
- Veterinary Orthopedics
- Feline Medicine
- Surgical Pathology
Background:
- Osteochondritis dissecans (OCD) is a developmental orthopedic disease affecting subchondral bone and articular cartilage.
- OCD in cats, particularly of the femoral condyle, can lead to progressive lameness and joint instability.
- Early diagnosis and appropriate surgical intervention are crucial for favorable outcomes in affected animals.
Observation:
- A 9-month-old domestic shorthaired cat presented with progressive right hind limb lameness.
- Radiographic and physical examination findings were consistent with osteochondritis dissecans of the lateral femoral condyle.
- The condition was confirmed intraoperatively during a stifle arthrotomy.
Findings:
- Surgical treatment involved removal of the cartilage flap and curettage of the underlying bone.
- The cat initially recovered from the right hind limb lameness.
- A similar lesion subsequently developed in the contralateral limb and was treated surgically with identical procedures.
Implications:
- This case highlights the potential for bilateral presentation of osteochondritis dissecans in feline stifle joints.
- Successful surgical management of OCD in cats can restore limb function and soundness.
- Further research into the etiology and predisposition of feline OCD may aid in preventative strategies.
