Outcome after Tibial Plateau Levelling Osteotomy and Modified Maquet Procedure in Dogs with Cranial Cruciate Ligament Rupture

Abstract

Objective The aim of this study was to compare outcomes after tibial plateau levelling osteotomy (TPLO) and modified Maquet procedure (MMP) for the treatment of cranial cruciate ligament rupture (CCLR) in dogs using clinical and radiographic evaluation and treadmill-based force plate gait analysis. Study Design This study was a prospective, randomized, controlled study. Materials and Methods Sixty-one dogs (76 joints) with CCLR were treated with TPLO (n = 30 dogs, 41 joints) or MMP (n = 31 dogs, 35 joints) and compared with a control group of 16 healthy Labrador Retrievers. Outcomes after surgery were compared by clinical orthopaedic assessment, radiographic evaluation and force plate gait analysis performed preoperatively, and then at 6 weeks, 3 and 6 months postoperatively. For objective comparison of ground reaction forces, the data were compared with the control group. Major complications were reported. Results A significant improvement in ground reaction forces was reached in all surgically treated dogs. No significant difference was found between the surgical methods at any postoperative re-examination. With regard to peak vertical force (PVF), there were significantly more patients with TPLO within the reference range of healthy dogs at the 3 months re-examination than dogs with MMP. There was no significant difference in mean value comparisons between TPLO and control groups 6 months postoperatively. Compared with the control group, mean values of 93.9% (PVF) and 85.9% (vertical impulse [VI]) were reached by the TPLO group and 89.4% (PVF) and 79.9% (VI) by the MMP group, 6 months postoperatively.No significant differences were found regarding major complications or progression of osteoarthritis. Conclusions Although no significant differences were found between the surgical methods, TPLO patients showed superiority with regard to clinical outcome.

Outcome after Modified Maquet Procedure in dogs with unilateral cranial cruciate ligament rupture: Evaluation of recovery limb function by use of force plate gait analysis

“…Our sequential radiographs confirmed the titanium foam wedge’s early osteointegration at 30 days, followed by complete osteointegration by 90 days post-surgery. The reported complication rate following the MMP technique varies between 20% in a study reporting only a major complication rate [ 12 ], and 23% in a study in which minor and major complications rate are summarised [ 6 ]. The major complications reported in a recent study included late meniscal lesions, implant removal due to seroma formation, implant breakage or loosening, tibial fracture and wound complications [ 12 ].…”

“…The reported complication rate following the MMP technique varies between 20% in a study reporting only a major complication rate [ 12 ], and 23% in a study in which minor and major complications rate are summarised [ 6 ]. The major complications reported in a recent study included late meniscal lesions, implant removal due to seroma formation, implant breakage or loosening, tibial fracture and wound complications [ 12 ]. Our study experienced a relatively low major complication rate (8.5%); one case developed a surgical site infection that required medical treatment to resolve, and two dogs suffered a tibial tuberosity fracture.…”

“…Force-plate analysis has been used in several studies to compare the clinical outcome of different surgical techniques objectively, and a cohort of healthy dogs has always been used as a control group [ 10 – 12 , 14 ]. GRFs are influenced by conformation and body size, making a comparison with a control group not always reliable [ 26 ].…”

“…To our knowledge, there is only one study in the veterinary literature that assessed outcomes of dogs undergoing MMP for the treatment of CCLR using force plate gait analysis and healthy dogs as a control group [ 12 ].…”

Clinical efficacy of Curcuvet and Boswellic acid combined with conventional nutraceutical product: An aid to canine osteoarthritis

“…All dogs recruited were free of any compound purported to relieve the clinical signs of OA in order to provide rigorous evidence of the therapeutic potential of curcuvet1 and boswellic acid. Force-plate analysis has been used in several studies as a method to objectively compare the clinical outcome of different surgical techniques or medications [23,24]. Use of force-plate analysis provided accurate and repeatable data on limb function and objective measurement of the efficacy of nutraceutical treatment [23].…”
