Long-term outcome of an intra-articular allograft technique for treatment of spontaneous cranial cruciate ligament rupture in the dog

SummaryObjectives: To describe the complications, short and long-term outcome and owner satisfaction of dogs with cranial cruciate ligament rupture treated with a recently described new osteotomy for the modified Maquet technique (N-MMT).Materials and methods: Medical records and radiographs of 82 dogs (84 stifles) were reviewed. Details regarding short-term outcome and complications were recorded from the medical records. Long-term follow-up information was obtained by telephone interview. Historical data and complications were statistically analysed.Results: Major complications occurred in 34/84 stifles. Intra-operative complications occurred in 26/84 stifles, all of which were fissures or fractures of the cortical hinge. Twenty-one of these fractures or fissures were repaired with a figure-of-eight wire. The second most common major complication was late meniscal tears in 3/84 stifles. One dog sustained a complete tibial fracture. Non-displaced fracture of the cortical hinge was the most common postoperative minor complication, which occurred in 5/84 stifles. The median preoperative lameness score was 3 out of 6. Final in-hospital re-evaluation of limb function was available in 58 dogs. The median lameness score at that time was 0 out of 6. Development of osteotomy related complications was not associated with a significant change in the postoperative lameness score.Clinical significance: Subjectively assessed clinical outcome with the N-MMT was good to excellent in this cohort of dogs. However, a high rate of intra- and postoperative complications of the N-MMT procedure was also present in these dogs.

Cranial Cruciate Ligament Rupture

Abstract Objective The aim of this study was to describe short- and mid-term outcomes, complications, implant bioabsorption and owner satisfaction for a modified Maquet procedure (MMP) in which a novel bioabsorbable citrate-based implant is used as the wedge component to treat cranial cruciate ligament rupture in client-owned dogs. Study Design Prospective clinical study of dogs (n = 13) undergoing MMP (n = 15). Intraoperative complications, postoperative complications, clinical follow-up using a 5-point lameness score and radiographs at 8 weeks and 6 months postoperatively were obtained. Mid-term outcome was assessed via physical examination, radiographs, canine orthopaedic index and owner satisfaction questionnaires. Results No catastrophic complications occurred. Major complications occurred in 3/15 stifles. All were surgical site infections and one case required implant removal. Minor complications occurred in 9/15 stifles. Non-displaced cortical hinge fractures were the most common minor complication, and these occurred intraoperatively (4/15) or postoperatively (2/15). Three dogs achieved full function, eight dogs acceptable function and the outcome was unacceptable in two dogs. Most owners were satisfied with the procedure (11/13). Complete implant bioabsorption was not confirmed on mid-term radiographs. Conclusion The described MMP with a citrate-based implant can produce satisfactory mid-term results. However, the long-term outcome of this procedure must be evaluated and technical modifications need to be implemented prior to larger-scale use of this implant.

Cranial Cruciate Ligament Rupture

SummaryObjective: To compare the resulting complications, short-term results, and client satisfaction for treatment of cranial cruciate ligament rupture using either unilateral or bilateral single-session tibial tuberosity advancement (TTA) in dogs.Methods: Medical records of 68 dogs (101 stifles) undergoing unilateral or bilateral single-session TTA were evaluated. Data gathered included signalment, history, physical examination findings, anaesthesia and surgical time, type of cranial cruciate ligament rupture and meniscal injury, implants, and intra-operative and postoperative complications. A mixed effect logistic regression analysis was performed to determine if complications were grouped by surgical procedure. Linear regression was performed to determine the influence of the variables on the occurrence of complications. Values of p <0.05 were considered significant.Results: No major intra-operative complications occurred. Twenty stifles (20%) developed a complication after surgery (11 minor, 9 major). There was no significant difference in occurrence of complications between dogs undergoing unilateral (n = 8) or bilateral single-session (n = 12) TTA (p = 0.69). The only risk factor found to be associated with complication occurrence was age.Clinical significance: This is the first report evaluating the use of bilateral simultaneous TTA. There was no significant difference in complication rates between unilateral and bilateral single-session TTA. Additional evaluation is needed to fully determine the extent of complications and long-term outcome of bilateral single-session TTA.
