“…The application of TPLO in cats is a controversial subject. In 2018 an ex vivo study was published whose outcomes failed to demonstrate the stabilizing effects of tibial plateau levelling osteotomy on cranial tibial subluxation and tibial rotation angle in a feline model [23].…”

This study aimed to evaluate the clinical and radio graphical outcome of cats following TPLO surgery for cranial cruciate ligament deficiency. Each cat underwent orthopedic assessment, pre-operative radio graphical evaluation, surgical procedure, postoperative management and clinical re-examination 1, 2, and 12 months following surgery. Age, body weights, TPAs, meniscal tears, implants and osteoarthritis progression were recorded. Postoperative OA score was compared with that obtained 1 year after surgery using a paired t-test with commercially available software. Radio graphical evaluation performed 1 year after surgery showed no significant OA progression (P-value > 0.1). Minor complications occurred in one case (#7) in which a mild to moderate seroma was observed ten days after surgery. No major complications were recorded. Although TPLO surgery in cats remains controversial, this study suggests that it was a suitable option for surgical treatment of feline cranial cruciate ligament rupture, but considering the ex vivo outcomes recently published, further in vivo evaluation is strongly recommended.

“…Different locations have been described, but all were localized in the same area, between the insertion of the patellar ligament on the tibial crest and the cranial extremity of the tibial plateau. [16][17][18] As no other description exists for ferrets, we elected to drill the hole in this area. Nevertheless, because of the very small size of the tibia, particular attention should be given when drilling hole because any mistake could lead to a malposition of the hole and a persistent instability of the stifle.…”

A 1‐year‐old, male, neutered ferret was presented with a history of 2 weeks of left hindlimb lameness. Orthopaedic exam and radiographs were consistent with a complete cranial cruciate ligament rupture. An extracapsular stabilization was performed. Progressive lameness improvement was observed during the first 15 days after surgery and a complete resolution was achieved 3 weeks after surgery. Twenty‐one months after surgery, no lameness or recurrence was reported and moderate osteoarthritis developed at radiographic follow‐up. This is the first case of surgical management of cranial cruciate ligament in a ferret with long‐term follow‐up. Even if this disease is rarely reported in this species, cranial cruciate ligament should be included in differential diagnosis of ferret's hindlimb lameness. Surgical management is feasible and could be considered as an alternative to conservative management.

“…Group 1: 'intact stifles' Each specimen (n = 14) was mounted onto the limb press with specified joint flexion angle (hip: 60°; stifle: 120±5°; tarsus: 120±5°). 14,15 Fixation screws at the top-plate were fixed to inhibit upward or downward movement of the top plate. Turnbuckles were tightened to achieve the median PTL predetermined for each specimen, and load was applied until the force-plate measured the proper ground reaction force reflecting 5%, 10%, 20% and 30% BW.…”

“…The biomechanical effects of TTA and TPLO have been evaluated in cats, 14,15 using a downsized limb press derived from the canine model by Warzee et al 16 Both studies evaluated the femorotibial shear force by measuring cranial tibial subluxation. Radiographic assessment of feline cadaveric specimens before and after CrCL transection reflected hindlimbs standing at predefined angles while bearing a load of 30% body weight (BW).…”

Objectives This study aimed to compare the under-and-over technique, a type of intracapsular treatment, and the standard fabella-tibial suture, a method for extracapsular treatment, in achieving immediate, postoperative stifle stability after cranial cruciate ligament (CrCL) rupture by using a feline, custom-made limb-press model. Methods Cadaveric feline hindlimb specimens (n = 14) were positioned in the limb press at predefined joint angles (stifle joint: 120°; hock joint: 120°), and vertical loads of 5%, 10%, 20% and 30% body weight were applied statically. Mediolateral radiographic views were obtained of the stifles under each load before and after CrCL transection, as well as after treatment with either of the two surgical techniques, and differences in distance between two predefined radiographic points for each radiograph were analysed. Results The general linear model showed a significant effect of load ( P <0.01) and technique ( P = 0.004) and a significant interaction between load and technique ( P = 0.006) regarding craniocaudal stifle stability. Distances between predefined tibial and femoral reference points were consistently higher in transected CrCLs than in intact stifles. All standard fabella-tibial suture-treated stifles (n = 7) were stable at all loads tested. Of the seven under-and-over technique-treated stifles, one was unstable at 20% body weight load and three at 30% body weight load. Conclusions and relevance Our model, which appropriately reproduced certain aspects of domestic shorthair cat stifle mechanics, indicated that a 40 lb monofilament nylon prosthesis, tightened at 20 N, produces more favourable biomechanical stabilisation of craniocaudal cruciate-related stifle instability than a 0.5 cm wide strip of fascia lata applied intracapsularly.

Effect of Tibial Plateau Levelling Osteotomy on Cranial Tibial Subluxation in the Feline Cranial Cruciate Deficient Stifle Joint: An Ex Vivo Experimental Study

Abstract: Given that stabilization of the cranial cruciate ligament deficient stifle was not obtained in this model, simple transposition of the tibial plateau levelling osteotomy technique from the dog to the cat may not be appropriate.
