Canine total knee replacement performed due to osteoarthritis subsequent to distal femur fracture osteosynthesis

Abstract

A 27-kg German Shorthaired Pointer was referred for evaluation due to the complaint of left pelvic limb lameness and signs of pain in the left stifle joint. Radiographs revealed signs of a healed supracondylar femoral fracture that had been previously repaired at another hospital with an intramedullary pin and two cross pins. In addition, there were signs of severe osteoarthritis (OA). The OA had been managed medically with administration of carprofen and nutraceuticals for nine months without any improvement. Left total knee replacement (TKR) surgery was performed to alleviate signs of pain. The patient was assessed preoperatively and at six months, one year, and two years after surgery using radiology, force platform analysis of gait, thigh circumference measures, goniometry, and lameness evaluation. Following surgery, the dog resumed normal activity without any signs of pain and a good quality of life at 3.5 months. Force plate analysis found that peak vertical force on the TKR limb was 85.7% of the normal contralateral limb after two years. Total knee replacement was a successful treatment to manage knee OA associated with a healed distal femoral fracture and internal fixation in this dog.

An un-commissioned randomized, placebo-controlled double-blind study to test the effect of deep sea fish oil as a pain reliever for dogs suffering from canine OA

“…The following three parts were then included in every round of data collection: (i) Of a total of 19 pain related descriptive scale (0–4) questions on attitude, behaviour, and locomotion, 11 questions formed the owner-assessed HCPI, as described previously [44-47]. (This index now has a new English translation that is closer to the Finnish original; the HCPI-E2, but the validated original remains the same [47,48]). (ii) Two 10-cm VAS: one for lameness and the other for quality of life (QOL).…”

Effect of intraarticular inoculation of mesenchymal stem cells in dogs with hip osteoarthritis by means of objective force platform gait analysis: concordance with numeric subjective scoring scales

“…Kinetic gait analysis has become an accepted technique for accurate and objective evaluation of limb function in humans and animals [ 17 , 18 ]; for that reason, force platform gait analysis can be used as a tool to determine pain, disease, and healing of different units of the locomotor system [ 19 – 21 ]. In the same manner, this device is consistently used as an accurate, objective method to document the efficacy of different medical treatments of OA in dogs [ 22 – 25 ].…”

Custom‐built constrained uniaxial and rotating hinge total knee replacement in cats: Clinical application, design principles, surgical technique, and clinical outcome

“…The primary indication for total knee replacement (TKR) in dogs, just as in man, is end-stage osteoarthritis, 1,2 and the success of canine TKR with both commercial and custom-made implants has been previously demonstrated. [1][2][3][4][5] Feline TKR was first described in a trial in which researchers investigating human metacarpophalangeal joint prostheses used cats as an experimental model. 6 Subsequent researchers reported that a silicon human finger joint prosthesis could be used for TKR in cats, but studies were limited by a small sample size and a short observation period of only 3 months.…”
