Summary
The goal of this study was to evaluate different minimally invasive surgical options
as therapy for cranial cruciate ligament rupture and resulting meniscal injuries.
In this study, 81 stifle joints of dogs with complete or partial rupture of the cranial
cruciate ligament were treated with minimally invasive surgery at the Small Animal
Clinic of the University of Veterinary Medicine in Hannover. The patients were divided
into three groups depending on intraoperative diagnosis and the surgical technique
applied. The dogs in group I (n = 26) had an isolated rupture of the cranial cruciate
ligament (CCLR), while those in groups II (n = 26) and III (n = 29) also had an injury
of the medial meniscus. Re-section of the damaged meniscal part was performed by arthroscopically
guided partial meniscectomy (AGPM) on the dogs in group II, while minimally invasive
medial arthrotomy (MIMA) was used on the dogs of group III. All of the stifles were
stabilized with a modified lateral imbrication technique using a braided, synthetic,
absorbable suture material (Panacryl®). Six months after surgery 76.5% of all patients were examined clinically and 74.1%
radiographically for evaluation of the success of the different treatment techniques.
At this examination, there were no signs of lameness in 42.1% of group I (CCLR), 65.0%
of group II (AGPM) and 87.0% of group III (MIMA). Upon palpation, 75.8% of these stifle
joints were found to be stable. Radiographic evaluations did not show any indication
of progression of gonarthrosis in 73.3% of all stifle joints examined here.
