Cranial Cruciate Ligament Disease

SummaryObjectives: To compare the conformation of the proximal tibia evaluated on a medio- lateral radiograph between small and large dogs with cranial cruciate ligament disease (CCLD).Methods: Retrospective clinical study with dogs having radiographic evaluation and CCLD confirmed at surgery. The first group (n = 52) was comprised of dogs weighing less than 15 kg and the second group (n = 52) of dogs weighing more than 15 kg. The tibial plateau angle (TPA), the relative tibial tube-rosity width (rTTW), and the Z angle were measured on preoperative radiographs with imaging measurement software. Linear mixed models were used to assess the effect of weight, age, sex, and neutered status on radiographic measurements and to estimate interobserver variabilities.Results: The small dog group had a greater TPA (30.1° ± 5.3; p <0.001 with a mean difference of 4.9° [95% CI: 3.8–6.0]) and Z angle (69.9° ± 5.6; p<0.001 with a mean difference of 6.1° ([95% CI: 4.9–7.4]) than the large dog group. Sex and neutered status further influenced the TPA and Z angle val -ues. No significant effect was observed on the rTTW values. A strong correlation was found between the TPA and the Z angle (r = 0.61, p <0.001). Variances were not significantly different between observers. Overall the interobserver variability was low suggesting that agreement was good.Clinical significance: Small dogs with CCLD have a steeper tibial plateau than large dogs with CCLD. Sex and neutered status also had an effect on some measured variables. This anatomical difference could influence the surgical technique, which may affect the outcome. The good interobserver agreement suggests the observer is unlikely to influence surgical planning.

SummaryArthrographic and intraoperative evaluations of stifles affected with cranial cruciate disease were compared. Arthrography did not appear to be helpful in predicting cranial cruciate ligament pathology. The caudal cruciate ligament was consistently not visualized in the arthrograms and was normal at surgery. The menisci were visualized consistently in the arthrograms, but conclusions could not be made as to the benefit of arthrography in predicting meniscal pathology. Arthrography was not helpful in predicting joint capsule and femoral articular surface pathology. Survey radiographic evaluation was better than arthrography in evaluating joint pathology. When cruciate injury is suspected, after history and physical examination, survey radiographs are better than positive contrast arthrograms at supporting the diagnosis.Positive contrast arthrography was evaluated as a diagnostic aid in canine cranial cruciate ligament disease. It did not appear to be useful in predicting joint pathology. With arthrography, both menisci could be visualized and evaluated for abnormalities. Joint effusion and presence of osteophytes evaluated on survey radiographs was better than arthrography in evaluating joint pathology.

SummaryObjectives: To investigate the conformation of the proximal tibia in small breed dogs with and without cranial cruciate ligament disease (CCLD) and to identify morphologic abnormalities that may predispose to development of CCLD.Methods: Mediolateral radiographs of the entire tibia of dogs <15 kg with surgically confirmed CCLD were retrospectively evaluated. Proximal tibial width (PTW), tibial plateau length (TPL), tibial plateau angle as described by Slocum and Slocum (sTPA), proximal tibial tuberosity angle (PTTA), tibial plateau angle as described by Inauen and colleagues (nTPA), and diaphyseal tibial width (DTW) were measured. The same variables were obtained from mediolateral radiographs of the entire tibia of dogs <15 kg without CCLD. In addition, a quotient nTPA/ PTW, relative tibial tuberosity width (rTTW), and relative body weight (rBW) were calculated for each dog. Independent two-sample t-test (p = 0.05) was used to compare mean ± SD of all measured variables between the two groups.Results: Gender, age, and weight mean ± SD were not significantly different between the two groups of dogs (p <0.05). Dogs with CCLD had significantly greater sTPA (p = 0.015) and rBW (p = 0.016).Clinical significance: In dogs of small breeds, a combination of an excessively steep tibial plateau and an increased relative body weight may predispose to early CCLD development. The slope of the tibial plateau was found to be caused by an abnormal caudal angulation of the proximal tibia, a phenomenon previously associated with CCLD development in small breed dogs in individual cases.

Malignant Neoplasia

An 11-year-old Border collie was presented for left hindlimb lameness associated with cranial cruciate ligament disease. The history included right tibial plateau levelling osteotomy performed approximately two years previously, with a subjectively good outcome. Multiple myeloma had been diagnosed approximately two months before presentation of the left hindlimb lameness. Medical treatment of multiple myeloma included glucocorticoids (prednisolone) and melphalan. Stabilisation of the left stifle was performed with the Simitri Stable in Stride extracapsular articulating implant. The dog demonstrated weightbearing on the operated limb within 24 hours following surgery. Re-examination six weeks following surgery revealed mild left hindlimb lameness, no resentment to manipulation of the left stifle, no cranial tibial thrust and a mild reduction in the range of motion. Hindlimb function was affected by various neurological events considered secondary to the malignant neoplasia; however, left stifle function was good until euthanasia 11 months following surgery.

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.

Objective The aim of this study was to compare complications between dogs with bilateral cranial cruciate ligament disease treated with single-session bilateral tibial plateau levelling osteotomies (BSSTPLO) versus staged bilateral TPLO (STPLO) procedures stabilized with locking plates. Study Design Medical records of client-owned dogs treated with BSSTPLO or STPLO stabilized with locking plates between March 2017 and July 2018 at two associated institutions were reviewed. Patient data and complications from 37 dogs with BSSTPLO and 18 with STPLO were compared between groups. Major complications were defined as any complication that required further surgical or medical treatment whereas minor complications did not. Results Incidence for major complications for BSSTPLO and STPLO was 7/37 and 6/18 respectively. Incidence for minor complications for BSSTPLO and STPLO was 3/37 and 2/18 respectively. No significant differences in minor or major complication rates existed between study groups (p = 0.2). Mean body weight was significantly higher in the STPLO group (p = 0.001); however, no correlation between weight or BCS and complication rate existed within either group. Increasing age was the only significant risk factor for major complications (p = 0.01) in either group. Conclusion Our findings support the claim that BSSTPLO and STPLO performed with locking implants have similar complication rates. The decision to perform BSSTPLO or STPLO in dogs with bilateral cranial cruciate ligament disease should be based on other considerations rather than just complication rates.

Cranial Cruciate Ligament Disease

SummaryThe tibial plateau levelling osteotomy (TPLO) is one of the most common surgical procedures used to treat cranial cruciate ligament disease in dogs. Complications occurring during or after TPLO can range in severity from swelling and bruising to fracture and osteomyelitis. Ten to 34% of TPLO surgical procedures are reported to experience a complication and approximately two to four percent require revision surgery to address a complication. Although the risk factors for many complications have not been fully assessed, the best available evidence suggests that complications of TPLO can be reduced with increased surgeon experience, careful surgical planning, and accurate execution of the surgical procedure. Identification of known or suspected risk factors and intraoperative technical errors allow subsequent action to be taken that is aimed at decreasing postoperative morbidity. There is a need for prospective studies with consistent data reporting in order to fully reveal the incidence risk factors for complications associated with TPLO.

Summary Objectives: To compare tibial plateau angle (TPA) among Labrador Retrievers, Rottweilers, Boxers, and German Shepherd Dogs that had undergone tibial plateau leveling osteotomies (TPLO) for cranial cruciate ligament disease, and to determine if higher TPAs are associated with increased risk for concurrent meniscal injury. Methods: This was a retrospective study including 275 client-owned dogs of one of the four aforementioned breeds that received TPLO radiographs between 1999 and 2005 prior to undergoing the TPLO procedure. The TPA measured by the original surgeon was compared among four breeds and analyzed with respect to presence or absence of meniscal injury diagnosed via arthroscopy or arthrotomy at the time of surgery. Results: Labrador Retrievers, Rottweilers, Boxers, and German Shepherd Dogs had mean TPAs of 25.9°, 26.2°, 25.9°, and 28.2°, respectively. The TPA of German Shepherd Dogs was significantly higher than that of the other breeds of dogs examined. TPA higher than the mean for dogs in this study did not significantly increase the risk for concurrent meniscal injury. Clinical significance: German Shepherd Dogs with cranial cruciate ligament disease had a significantly higher TPA compared to the other breeds examined. Higher TPA did not increase the likelihood of meniscal tears in this study. However, several variables that were not assessed, including the degree of cranial cruciate ligament integrity at the time of surgery and the time between original CrCL deficiency and surgical assessment, could have affected this analysis.
