Cranial Cruciate Ligament Rupture

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.

Cranial Cruciate Ligament Rupture

 Background: It is believed that the inclined tibial plateau angle to be a major cause of cranial cruciate ligament (CCL) rupture, and the treatment of this disease is the tibial plateau leveling for decrease the cranial tibial thrust. However, there are breeds predisposed to rupture of the cranial cruciate ligament and in this patterns breed the tibial plateau is more in­clined due to the conformation of the limb. The aim of this communication was to evaluate the effectiveness of the locking screw and cauterizing the growth plate of the tibial plateau as a preventive method of cranial cruciate ligament rupture. Case: In a young dog, one stifle joint randomly chosen for placing a screw in order to block the tibial plateau growth line. There was placed a 3.5 mm x 20 mm cancellous bone screw in the dorsocranial surface of the tibial plateau of the left hindlimb. Two months after the first surgical intervention, the contralateral limb was cauterized in the tibial plateau growth line. Electrocauterization was performed with a spatula electrode set at 60 watts, performing ablation on the cra­nial third of the tibial plateau physis with access to the medial and lateral surfaces of the proximal tibia. The electrode was placed against the physis for 10 seconds at each site. Both members were followed radiographically to measure the tibial plateau angle and observed the angle reduction. After 30 and 60 days post-surgery, the tibial plateau angle in left hindlimb decreased to 11o and -4o, respectively. However, the decrease plateau tibial angle was intense and severe and the screw was removed of the bone. However, even with the proximal tibial physis still open, withdrawing the screw did not alter the tibial plateau angle, which remained at -4º until the animal reached adulthood. The right left hindlimb was used as a control until the dog was 6 months old, when the tibial plateau angle exhibited a 26°. With the electrocauterization technique the tibial plateau angle decreased to 18° and 16° at 30 and 60 days after surgery, respectively, remaining at this last value until the animal completed its growth. Discussion: In the animals with cranial cruciate ligament rupture is indicate same surgical procedures like tibial plateau leveling osteotomy. In these cases, the recommended tibial plateau angle is aproximattely 5o. This study sought to block the line of growth of the tibial plateau to be reached an angle of approximately 5o. Epiphysiodesis technique with screw was already described for treating CCL rupture in young dogs, and the tibial plateau slope was reduced in all dogs studied. The surgical technique used was effective in blocking the physis; however, we observed that the tibial plateau slope was excessively modified and the screw was removed. This fact is explained by the dog’s immaturity, since the plateau leveling occurs more intensively in very young dogs. In epiphysiodesis using the electrocauterization technique, the same surgical principle of juvenile pubic symphysiodesis for treating coxofemoral dysplasia was used. However, in the current pilot study, it was unable to achieve the desired tibial plateau slope with this technique, possibly due to performing the procedure at an age in which the proximal tibial physis would have limited functional capacity. In this study, there was a reduction in the angle of the tibial plateau in both the techniques. However, further studies should be conducted to in order to confirm the actual effectiveness of both techniques described in this report.

Cranial Cruciate Ligament Rupture

Abstract Objective This study investigated variables associated with surgical site infection (SSI) in dogs with cranial cruciate ligament rupture managed with stifle joint examination and lateral fabellotibial suture stabilization. Study Design A retrospective study of dogs that had stifle arthroscopy, stifle arthrotomy, or a combination of both, followed by lateral fabellotibial suture stabilization for cranial cruciate ligament rupture. All cases had a minimum follow-up of 90 days. Lameness grades were recorded preoperatively, and at 6-week and final follow-up. Results One hundred fifty procedures in 130 dogs met the inclusion criteria. Overall, SSI rate was 17.3% and removal of the lateral fabellotibial suture was performed in 53% of SSI. Multivariable analysis showed significant association between SSI and bodyweight (p = 0.013), and induction using propofol (p = 0.029). Multilevel ordinal logistic regression analysis showed a greater proportion of dogs had a higher lameness grade at 6-week (p = 0.021) and final follow-up (p = 0.002) assessments in the infected compared with non-infected dogs. Conclusion Our study demonstrated a higher SSI incidence than previously reported in dogs undergoing a lateral fabellotibial suture for cranial cruciate ligament rupture. Bodyweight and induction with propofol were identified as significant risk factors for postoperative SSI. Owners could be advised of an increased SSI risk in larger dogs and consideration should be given to selection of induction agent. Dogs that develop an SSI have a worse lameness grade at 6-week and final follow-up.

SummaryMeniscal tears and subchondral bone marrow lesions have both been described in dogs with cranial cruciate ligament rupture, but their possible concurrence has not been evaluated. In a population of 14 dogs exhibiting signs of stifle pain with surgically confirmed cranial cruciate ligament rupture, a short presurgical 1.5T magnetic resonance (MR) imaging protocol including dorsal proton density, dorsal T1-weighted gradient recalled echo, and sagittal fat-saturated dual echo sequences was tested to further investigate these features and illustrate meniscal tears. Interobserver agreement for detection of medial meniscal tears (k = 0.83) and bone marrow lesions (k = 0.87) was excellent. Consensus MR reading allowed detection of nine out of 12 surgically confirmed medial meniscal tears and there was no false positive. All dogs had cruciate ligament enthesisrelated bone marrow lesions in the tibia, femur or both bones. Additionally, among the 12 dogs with confirmed medial meniscal tears, subchondral bone marrow lesions were present in the caudomedial (9 dogs) and caudoaxial (11 dogs) regions of the tibial plateau, resulting in odds ratios (13.6, p = 0.12, and 38.3, p = 0.04, respectively) that had large confidence intervals due to the small group size of this study. The other two dogs had neither tibial bone marrow lesions in these locations nor medial meniscal tears. These encouraging preliminary results warrant further investigation using this clinically realistic preoperative MR protocol. As direct diagnosis of meniscal tears remained challenging in dogs even with high-field MR, identification of associated signs such as subchondral bone marrow lesions might indirectly allow suspicion of an otherwise unrecognized meniscal tear.
