Cranial Cruciate Ligament Rupture

SummaryThe objective of the present study was to determine the tibial plateau angle (TPA) in cats without stifle pathology and to compare it with cats suffering from an isolated cranial cruciate ligament rupture. Mediolateral radiographs of the stifle were taken and the tibial plateau angle was measured based on the method previously described by Slocum and Devine (1983) for dogs. Three observers with different levels of experience evaluated the radiographs of all of the cats in this study. The mean tibial plateau angle measured by all three observers in the cats with a rupture of the cranial cruciate ligament (CCL) was 3.1° greater than in cats without stifle pathology. Neither gender, age, body weight nor degenerative joint disease had an influence on measurement results. The authors found an inter-observer variability of ± 5.3°. Hence it can be concluded that cats with cranial cruciate ligament rupture have a greater TPA, and this at least lends some credence to the possibility of higher TPA being a predis-posing factor for cruciate injury in this species.

Cranial Cruciate Ligament Rupture

Cranial cruciate ligament rupture is the major cause of lameness and degenerative joint disease in the canine stifle. The cause of this disease is multifactorial, especially involving degenerative and inflammatory changes. Many techniques have been described for the management of this condition, and current recommendations include the use of corrective osteotomies, most recently using the Maquet (or modified Maquet) procedure. This technique is fundamentally similar to the classical tibial tuberosity advancement (TTA), but without the use of the bone plate. The main advantages of using this technique are a shorter operative time and less use of implants. The main complication of this technique is an increased risk of tibial crest fracture. This report describes the Maquet technique for the treatment of a three-year-old male West White Terrier dog with rupture of the cranial cruciate ligament. Cruciate ligament rupture was diagnosed by a positive cranial tibial drawer test. Mediolateral stifle radiography performed under anesthesia with the stifle in 135° of extension demonstrated a tibial plateau angle of 22°. A cage of six millimeters was necessary to allow advancement. The Maquet technique produced excellent post-operative results, including early weight-bearing and neutralization of the cranial tibial drawer. The consolidation time of the osteotomy was 63 days.

Cranial Cruciate Ligament Rupture

SummaryThe objective of this study was to determine whether clinical outcomes were superior and complication rates were lower in dogs that had had a cranial cruciate ligament rupture treated by tibial plateau levelling osteotomy (TPLO), compared to those dogs that had been treated using the original cranial tibial wedge osteotomy (CTWO) procedure. Thirty-seven client-owned dogs with cranial cruciate ligament rupture were included in the study: 19 dogs underwent a TPLO procedure, and 18 dogs underwent a CTWO procedure. The study was retrospective, with the data being obtained from medical records and a review of radiographs. The long-term outcome was assessed by means of an owner questionnaire using a visual analogue scale. For the majority of factors that were reviewed, there was not a significant difference in outcome between the dogs that had a TPLO or those that had undergone a CTWO. All of the dogs showed a rapid return to weight bearing after surgery, and at the six week re-examination, the majority of the dogs did not have any pain on stifle palpation. They displayed a good stifle range of motion and significantly lower lameness scores than those prior to surgery. The complication rates did not differ between the procedures, however, within this small sample of dogs, complications following a CTWO were more likely to require revision surgery.

Improved Outcome

PICO question In dogs over 15 kg, with cranial cruciate ligament rupture is there evidence of improved outcome following tibial plateau levelling osteotomy or lateral fabellotibial suture? Clinical bottom line Although the evidence is not conclusive, the literature reviewed here suggests that tibial plateau levelling osteotomy (TPLO) results in superior limb function and owner satisfaction compared to placement of a lateral fabellotibial suture (LFS). There is currently insufficient evidence to determine if there is a difference in complication rates or osteoarthritis (OA) development following TPLO or LFS.

Abstract Objective The aim of this study was to report efficacy of a modified tibial plateau levelling osteotomy (TPLO) with double cut and medial crescentic closing wedge osteotomy (TPLO/MCCWO) to treat dogs with cranial cruciate ligament rupture and concurrent tibial valgus. Study Design This study was a cases series. Materials and Methods Medical records of dogs that had TPLO with medial crescentic closing wedge osteotomy were reviewed. Data collected included signalment, body weight, pre- and postoperative tibial valgus angle, tibial plateau angle (TPA), surgical planning, corrective osteotomy technique, method of fixation, complications, and length of time to radiographic healing. Results Fifty-two surgical procedures performed in 45 dogs (7 bilateral) were included in the study. Mean age at surgery was 54 months, and body weight ranged from 5 to 63 kg (mean: 36.5 kg). Mean pre- and postoperative mechanical medial proximal tibial angle were 101° (98°–107°) and 92.80° (88°–97°) respectively. The mean pre- and postoperative TPA were 27.80° (16–35°) and 6.50° (3–11°) respectively. Intraoperative complications occurred in two stifles: in one stifle over-rotation of the proximal tibial segment resulted in a TPA of –8°, with immediate revision to a 5° TPA; in the second stifle a fissure of the lateral tibial cortex developed during insertion of a screw and required adjunctive fixation. No postoperative complications were recorded and all osteotomies healed uneventfully. Conclusions Tibial plateau levelling osteotomy/medial crescentic closing wedge osteotomy is an effective treatment for dogs with cranial cruciate ligament rupture and tibial valgus allowing accurate correction of the tibial deformity with a low complication rate.

Cranial Cruciate Ligament Rupture

Patellar desmopathy in dogs after tibial plateau levelling osteotomy has been described in many studies. Tibial tuberosity advancement is a biomechanically different technique. It is assumed that the patellar ligament is loaded with little force similarly as after tibial plateau levelling osteotomy. Various aspects related to secondary patellar desmopathy are not completely understood. This study deals with computed radiography measurement of patellar ligament thickness after tibial tuberosity advancement in dogs with cranial cruciate ligament rupture. The thickness of the patellar ligament in exactly predetermined locations was measured from mediolateral radiographs of stifle joints. A total of 18 dogs (20 knee joints) with cranial cruciate ligament (ligamentum cruciatum craniale) rupture underwent three radiographic examinations of the knee (preoperative examination and control examination 7 and 15 weeks after the surgery). Significant difference was found between the thickness of the patellar ligament in the first and second examinations. Some of the demographic factors possibly related to patellar ligament thickness (age, sex, body weight, type of cranial cruciate ligament rupture, arthrotomy, cage size, meniscal injury, time between surgery and radiographic examination) were analyzed. However, statistical analyses did not show any effect of these factors on the thickness of the patellar ligament, except for the time between surgery and radiographic examination. These findings can extend the surgeons’ knowledge of biomechanical aspects of tibial tuberosity advancement.
