Abstract Background Cranial cruciate ligament rupture (CCLR) is one of the most common causes of pelvic limb lameness in dogs. Risk factors for CCLR include breed (especially large and giant breeds), body weight, gender and spay/neuter status, and age. Few studies have evaluated physical activity and fitness indicators, however, as risk factors for disease. This study used an online questionnaire distributed primarily via social media to assess risk factors for CCLR in dogs actively engaged in agility training or competition to determine demographic and physical activity factors associated with rupture. Results Data from 260 dogs with CCLR were compared to similar data from 1006 dogs without CCLR. All dogs were actively training or competing in agility at the time of CCLR or the time of data submission, respectively. Physical characteristics associated with increased risk of CCLR included younger age, spayed female sex, greater body weight, and greater weight to height ratio. Agility activities associated with increased odds ratios included competition in events sponsored by the North American Dog Agility Council (NADAC), competing at novice and intermediate levels, and competing in fewer than 10 events/year. Odds ratios were lower in dogs that competed in events sponsored by United Kingdom Agility International (UKI). Other activities associated with increased odds ratio for CCLR included involvement in flyball activities and short walks or runs over hilly or flat terrain on a weekly basis. Activities associated with decreased odds ratio included involvement in dock diving, barn hunt, nosework, or lure coursing/racing activities and participation in core balance and strength exercises at least weekly. Conclusions These results are consistent with previous studies demonstrating that body weight and spay/neuter status are risk factors for CCLR in dogs. This is the first report to demonstrate that risk of CCLR in agility dogs is decreased in dogs that engage in regular core strengthening exercises, compete more frequently, compete at higher levels, and compete in more athletically challenging venues.

Concomitant cranial cruciate ligament rupture (CCLR) is a common complication in small breed dogs with patellar luxation (PL) with an elusive pathogenesis. Surgical treatment is available and commonly includes remodelling osteotomies. While these modern techniques have shown good functional results, access is limited due to the high costs for owners and the need for special surgical equipment. The objectives of the study were to evaluate the frequency and risk factors for concomitant CCLR in small breed dogs with PL. To study the outcome and complications of the combination of the Wedge recession osteotomy (WR) and Tibial tuberosity transposition (TT) with a Fascia over-the-top (OT) or a Capsular and fascial imbrication technique (CFI) for the simultaneous treatment of PL and concomitant CCLR. A retrospective study is presented here. The signalment, body weight, luxation grade and direction, affected side, bilateral or unilateral PL, CCLR and meniscal status were analysed. The surgical treatment for PL and concomitant CCLR, outcome and complications were investigated. Of 233 small breed dogs with PL, 52 (22.31%) had a concomitant CCLR. Maltese dogs were more likely to have concomitant CCLR. The mean age for the dogs with PL only was 5.32 years, which was significantly younger than the mean age of dogs with PL and concomitant CCLR (7.39 years). Overweight dogs with PL were prone to develop concomitant CCLR. Surgical stabilisation with a combination of WR, TT and OT or CFI had excellent or good results in 86.63% of the cases, while 16.67% of the cases developed complications. In conclusion, PL and concomitant CCL ruptures can be managed successfully by performing a combination of WR, TT and OT or CFI. The outcomes and complication rates are comparable to remodelling osteotomies. Moreover, these techniques are less expensive and can be performed with standard surgical equipment. These findings should be beneficial for clinical diagnosis, client education and treatment.

SummaryPatients at the Blue Star Foundation animal hospital in Gothenburg, Sweden, underwent a procedure with an extracapsular suture technique for cranial cruciate ligament rupture. Two groups were compared; one of the groups received rehabilitation by the owner, and the other received professional rehabilitation by a trained physiotherapists. The dogs where reexamined at four, 12 and 24 weeks postoperatively. The results were ‘good’ in both groups but a difference was not seen between the groups. This study shows that in the dogs with a body weight of between 25 and 50 kg with cranial cruciate ligament rupture, the extracapsular suture technic gives good results, provided that the dogs are actively walked on the leash postoperativly.

SummaryThe effect of two suture types, monofilament polybutester and braided polyester, on stifle joint biomechanics after extra-articular repair of cranial cruciate ligament rupture was evaluated by analysis of the instant centre of motion. The instant centres of motion and resulting velocity vectors were determined radiographically on both stifles of eight fresh canine cadavers before and after cranial cruciate ligament transection. After ligament transection, all 16 stifles were repaired with an extra-articular technique utilizing a double strand of suture placed between the lateral fabella and the tibial tuberosity. One stifle on each cadaver was repaired with each suture type. The instant centres of motion and resulting velocity vectors were re-evaluated post repair. All stifles had normal instant centres of motion prior to transection of the cranial cruciate ligament. Neither ligament transection nor extra-articular repair with either suture type resulted in an abnormal change in the instant centre of motion.

The aim of this study was to evaluate if the modified Insall Salvati (IS) method can be applied for the canine patient despite differences of proximal tibial morphology, and if such potential differences are also seen in dogs with cranial cruciate ligament rupture. Insall Salvati method is a simple and convenient method for determination of the vertical position of patella, by dividing the length of patella by length of the patellar ligament. The influence of the variable proximal tibial morphology on the modified (IS) index was measured and the value of modified IS index in healthy dogs (n = 25) was compared with dogs with cranial cruciate ligament rupture (n = 26). Medio-lateral radiographs of 102 stifles were evaluated. Patellar ligament length (PLL), patellar length (PL), modified IS ratio and the height of insertion point of patellar ligament on tibial tuberosity were measured. Data of the IS ratio were compared with the value of the height of the insertion point with no significant difference (P = 0.36). There was no significant difference (P = 0.07) in the PLL:PL ratio between dogs affected or unaffected with cranial cruciate ligament rupture. Based on the results of this study we can conclude that the morphology of the cranio-proximal tibia and the height of insertion point of the patellar ligament do not have an influence on the value of the modified IS index both in healthy dogs and in dogs with cranial cruciate ligament rupture.
