Dysplasia surgery outcomes: honest expectations

EMReviewed by Eben Martin, Veterinary Surgeon · Updated August 2026

Total hip replacement succeeds in the large majority of cases, returning near normal function, with a small but real rate of serious complications like luxation or infection. FHO reliably relieves pain with a functional, slightly imperfect gait, best in lighter dogs. Elbow arthroscopy helps selected elbows but does not erase the underlying arthritis.

The honest ledger

  • THR: the large majority of dogs return to essentially normal activity; complications, luxation, infection, fracture, implant loosening, are uncommon but expensive when they happen, which is why surgeon volume and revision policy are fair questions
  • FHO: pain relief is reliable; the result is a functional pseudo joint with mildly reduced extension, excellent in light muscular dogs, more compromised over about 25kg
  • Arthroscopy: removing fragments helps many elbows meaningfully, but the elbow remains dysplastic and arthritis continues on a slower clock; lifetime management stays on the books
  • Juvenile procedures: genuinely change joint development when done in the narrow age window, which is their whole promise and their whole constraint

Choosing under uncertainty

The recurring owner dilemma is a large young dog with bad hips and a budget that covers FHO but strains at THR. There is no universally right answer: an FHO now is real and affordable relief; saving toward THR keeps the ceiling higher; and waiting too long forecloses nothing for THR but costs comfortable years. This exact dilemma, with your dog's x-rays and your actual numbers, is among the most common cases we are asked to referee, and among the most useful.

Common questions

Can an FHO be converted to a THR later if we save up?

Conversion is technically possible but harder and less predictable than a first time THR; it is a bridge to plan with a specialist rather than an assumed safety net. If THR is the likely destination, getting there directly is better.

My dog had THR and limps at week three. Panic?

Some gait wobble early is normal; the panic signs are sudden non weight bearing, rotation, shortening or a clunk. Anything sudden goes to the surgical centre the same day; gradual and improving belongs on the recheck list.
