Sagittal joint instability in the cranial cruciate ligament insufficient canine stifle. Caudal slippage of the femur and not cranial tibial subluxation.
OBJECTIVE This in vivo study qualitatively describes the sagittal motion pattern of the cranial cruciate ligament (CrCL) insufficient canine stifle in operated and unoperated joints with cranio-caudal laxity on palpation. MATERIAL AND METHODS Sagittal stifle kinematics were recorded in vivo in dogs (> 15 kg BW) with unilateral (n = 7) or bilateral (n = 6) complete CrCL rupture and positive cr...
متن کاملEffect of cold compression therapy on postoperative pain, swelling, range of motion, and lameness after tibial plateau leveling osteotomy in dogs.
OBJECTIVE To evaluate the effect of cold compression therapy (CCT) on postoperative pain, lameness, range of motion of the stifle joint, and swelling following tibial plateau leveling osteotomy (TPLO) in dogs. DESIGN Randomized, blinded, placebo-controlled clinical trial. ANIMALS 34 client-owned dogs with unilateral deficiency of a cranial cruciate ligament undergoing TPLO. PROCEDURES Dog...
متن کاملComputer-assisted gait analysis of the dog: comparison of two surgical techniques for the ruptured cranial cruciate ligament.
OBJECTIVES To compare the improvement in degree of lameness following surgical repair of cranial cruciate ligament rupture in dogs using computer-assisted gait analysis. METHODS Two groups of 14 dogs were used. One group was treated by a capsular-fascial imbrication method, and the other group by tibial plateau levelling osteotomy (TPLO). All dogs underwent gait analysis prior to surgery, as ...
متن کاملA comparison of outcomes following tibial plateau levelling osteotomy and cranial tibial wedge osteotomy procedures.
The 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 l...
متن کاملTreating Patellar Ligament Desmitis
Patellar ligament inflammation has been reported to follow tibial plateau leveling osteotomy (TPLO) procedures. While self-limiting, severe cases can result in marked lameness and prolonged recovery. Based on favorable results for shock wave therapy (SWT) of tendon and ligament injuries in other species, a clinical trial was conducted in dogs to determine if SWT would have a beneficial effect o...
