The DeAngelis technique involves placement of a prosthetic suture material, which is aligned to stabilize the joint and function as a replacement cruciate ligament.

The DeAngelis technique also slows the progression of arthritis and provides good results in smaller dogs (<15kg).

• Sudden onset lameness in one hind limb
• No or minimal weight bearing in one hind limb
• Intermittent limping which worsens with exercise (partial tear)
• Swelling of the knee joint
• Difficulty or stiffness rising or jumping

Cruciate ligament rupture or tear can often be diagnosed from a thorough history and physical examination (testing for cranial tibial thrust or cranial draw). Some more subtle tears may require radiographs or arthroscopic exam of the joint to diagnose.

Medical management involves cage rest and exercise restriction for several (3+) months, and is generally only an option for very small dogs and cats. The joint begins to stabilize with scar tissue over several months and results in significantly increased arthritis (when compared to surgical stabilisation). Function of the leg can be termed satisfactory, and requires ongoing management of osteoarthritis and pain.

Surgical stabilisation of cruciate rupture is recommended for almost all cases, and results are superior in 90% of cases.
