“… 8 – 10 Neutralisation of the cranial tibial thrust with a tibial plateau levelling osteotomy (TPLO) in cats remains controversial, achieving different results between ex vivo and in vivo studies. 11 – 13 Typically, its stabilisation involves a lateral fabellotibial suture, while a fibula-patellar suture treats caudal cruciate ligament (CaCL) rupture. 1 , 6 Joint immobilisation methods range from external coaptation to rigid transarticular external fixation, though controversy exists due to associated complications.…”

Case summary An 11-year-old female neutered domestic shorthair cat was referred for surgical management of a traumatic right stifle luxation. Orthopaedic examination of the affected stifle under general anaesthesia revealed joint effusion and craniocaudal and rotational instability. Cranial displacement of the tibia with respect to the femur and infrapatellar pad sign were identified on radiography. Intraoperatively, complete rupture of both cruciate ligaments and marked disruption of the mid and caudal poles of the medial and lateral menisci were observed. Both collateral ligaments appeared intact. The remnants of the injured cruciate ligaments were removed, and medial and lateral caudal hemimeniscectomies were performed. A tibial plateau levelling osteotomy (TPLO) was performed to address the craniocaudal stifle instability. Intraoperative assessment of the stifle revealed persistent instability with cranial tibial translation, internal and external rotation, and a positive caudal draw test. A lateral augmentation suture was employed to address the persistent cranial tibial translation and internal rotation. To successfully neutralise caudocranial and external rotational instability secondary to the caudal cruciate ligament deficiency, a medial augmentation suture was placed with the aid of three interference screws. Stifle stability was achieved. A modified Robert-Jones bandage was kept on for 24 h postoperatively. An excellent outcome was achieved, with successful limb function restoration. Relevance and novel information This case report represents the first documented instance of feline traumatic stifle luxation repair by combining a corrective tibial osteotomy and extra-articular augmentation. Notably, it introduces the novel technique of implementing a TPLO with medial and lateral augmentation sutures to address multidirectional stifle instability.

“…[1][2][3]5,7 Osteotomy techniques produce favorable outcomes in dogs compared to extracapsular procedures, and there are a small number of case series in cats documenting promising results with tibial osteotomy techniques. [8][9][10][11][12][13] The biomechanical properties of these 2 techniques used for stifle joint stabilization, with both osteotomies and extracapsular fixation, have been widely evaluated in dogs. [14][15][16][17][18][19][20][21] Nevertheless, there are limited reports available that assess the biomechanical behavior of extracapsular techniques for stifle stabilization in cats.…”

OBJECTIVE To compare the biomechanical properties of lateral femoro-fabella ligament suture (FFLS) and lateral suture with a bone anchor suture (BAS) for management of feline cranial cruciate ligament disease. ANIMALS 12 femurs from 6 mature cat cadavers. METHODS The samples were collected from April to June 2023. The specimens had an FFLS and, subsequently, BAS placed and were positioned into a biomechanical testing machine, preloaded from 5 N to 15 N for 100 cycles, and subsequently, a load to suture failure was applied. The displacement at 5 N and 15 N, the total precycle displacement (millimeters), the force at 3 mm displacement and at failure (newtons), the displacement at failure (millimeters), and the stiffness to failure (Newton:millimiter) were recorded. Nonparametric Wilcoxon signed-rank tests were used to compare data between the 2 groups. RESULTS The displacement at 5 N and 15 N and the total precycle displacement were significantly higher in the FFLS group compared to the BAS group. Additionally, the FFLS group results showed less consistent displacement and marked variability. The force (newtons) at 3 mm displacement was higher in the BAS group. There was no significant difference in force and no significant difference in displacement at failure between the 2 groups. However, the stiffness to failure (N/mm) was significantly higher in the BAS group. CONCLUSION BAS represented a more stable and reliable femur attachment for extracapsular suture in cats. CLINICAL RELEVANCE To demonstrate the stability and reliability between BAS and FFLS and influence implant selection in the treatment of cranial cruciate ligament rupture in cats with evaluation of biomechanical properties.

Tibial plateau levelling osteotomy in eleven cats with cranial cruciate ligament rupture

Abstract: The preliminary results of this study support the use of TPLO in cats, but larger case numbers are needed to evaluate its practicability, as well as long-term outcome (>1 year), especially evaluating the development and the clinical relevance of osteoarthritis.
