Study Notes
Surgical Treatment Options for Canine Cranial Cruciate Ligament (CrCL) Rupture
- Surgical treatment in mature dogs includes extracapsular techniques and osteotomy techniques for stabilizing the stifle joint
- Measures of treatment success for CrCL rupture include clinical stifle stability tests and radiographic evaluation
- Extracapsular techniques involve lateral fabellotibial suture and nylon leader lines for passive and dynamic stability
- Postoperative care for extracapsular techniques includes pain management, activity restriction, and rehabilitation
- Osteotomy techniques, such as tibial plateau leveling osteotomy (TPLO) and tibial tuberosity advancement (TTA), aim to neutralize dynamic cranial tibial translation
- Postoperative care for osteotomy techniques is similar to extracapsular techniques, with a longer activity restriction period
- Treatment options for immature patients include expedited surgical intervention and presurgical management
- Osteotomy techniques for immature dogs can interfere with growth plates, leading to growth deformities
- Comparing osteotomy techniques with extracapsular techniques, osteotomies offer better clinical outcomes and success in lean and small dogs
- Small dogs and cats require special consideration in surgical treatment, with options such as TPLO, TTA, and extracapsular techniques
- Comparison of surgical versus medical management shows that surgery combined with post-op medical management yields better outcomes in the long term
- Concurrent anomalies in CrCL deficient stifles, such as meniscal tears and patella luxation, need to be recognized and addressed during treatment
