LONG-TERM CLINICAL AND GONIOMETRIC FOLLOW-UP OF LATERAL SUTURE SURGERY IN DOGS WITH CRANIAL CRUCIATE LIGAMENT RUPTURE

Abstract

The aim of this study was to evaluate the complications and the short-, medium-, and long-term outcomes following treatment of cranial cruciate ligament (CCL) rupture in dogs using the lateral fa-bello-tibial suture technique. The patients were ten dogs of various breeds, 62.5 ± 18.8 months of age, weighing 30.2 ± 3.3 kg, with unilateral CCL rupture. At 2, 6, 12, 24, and 52 weeks after surgery, the dogs were re-evaluated with clinical examination, gait and pain analysis, and radiography. A major complication was identified in one dog (10%), requiring second surgery due to implant failure and destabilisation of stifle joint. Minor complications occurred in two dogs postoperatively (one late meniscal injury and one case of seroma formation). The short-term outcome at two and six weeks postoperatively was considered good in six dogs and satisfactory in four dogs, while the mid-term outcome (between 12 and 24 weeks) was good to excellent in eight dogs and satisfactory in two dogs. All ten dogs had a good to excellent outcome 52 weeks after surgery. The lateral suture technique is generally safe and given the major benefits, such as lower costs, lower technical difficulty, and minimal requirement for specialised equipment, will probably remain a popular and alternative method for treatment of CCL insufficiency in dogs with good degree of owner satisfaction.
