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
