Bodyweight is the primary criterion separating surgical from conservative management, with dogs weighing more than 15 kg having substantially worse outcomes without surgery and dogs weighing 15 kg or less showing reasonable functional recovery with conservative care.Preventive Vete…+2
The quantitative case for surgery in dogs over 15 kg is compelling. Among dogs managed non-surgically, only 19% of those weighing more than 15 kg were considered clinically normal or improved after an average follow-up of 3 years, compared with 86% of dogs weighing 15 kg or less.The Veterinary… Conservative treatment in overweight dogs over 20 kg carries a documented risk of treatment failure severe enough to result in euthanasia.Preventive Vete… Surgical management leads to reduced lameness and reduced analgesic prescription requirements compared with non-surgical management across the full range of body sizes.Preventive Vete…
In dogs weighing 15 kg or less, conservative management is a defensible first choice. Among small-breed dogs managed non-surgically, 86% were clinically normal or improved at 3 years, and one historic report found 90% of small-breed dogs had no owner-detectable lameness following conservative treatment.The Veterinary… The probability of surgery in UK primary-care practice reflects this: surgical management was chosen in 56% of dogs weighing less than 10 kg versus 86% of dogs weighing 40 kg or more.The Veterinary… Only 15.5% of UK veterinarians supported immediate surgical management for dogs under 15 kg.The Veterinary…
When surgery is chosen, TPLO is the preferred technique for dogs over 15 kg. Among Veterinary Orthopedic Society members, 78.6% preferred TPLO for dogs over 15 kg, compared with 13.9% for tibial tuberosity advancement (TTA), 5.9% for lateral fabellotibial suture (LFS), and 1.6% for the tightrope procedure.Journal of the… This preference was independent of board certification status.Journal of the… The available literature suggests TPLO provides better long-term outcomes than TTA and LFS.Journal of the… TPLO results in superior limb function and owner satisfaction compared with LFS.Veterinary Evid…
Additional clinical factors beyond bodyweight that influence the surgical decision include severity of lameness, degree of stifle instability, patient age, comorbidities, and owner financial constraints — though these have not been formally quantified in epidemiological analyses.The Veterinary…
For small-breed dogs where surgery is elected, TPLO produces good objective outcomes. Force plate gait analysis in dogs 15 kg or less treated with TPLO showed continuous improvement in hindlimb symmetry indices from 1 month postoperatively, reaching near-normal values at 6 months.Veterinary and… TPLO patients reached 93.9% of normal peak vertical force and 85.9% of normal vertical impulse at 6 months postoperatively.Veterinary and…
Surgical site infection (SSI) rate following TPLO is 3.0% to 10.8%, with overall complication rates of 18.8% to 28%. Risk factors for SSI include German Shepherd Dog breed, intact male status, increased bodyweight, longer anesthesia time, concurrent meniscectomy, reduced surgeon experience, and absence of postoperative antibiotics.Journal of the…
