Joint surgery in cats is 3 procedures with a 7-fold price gap between the cheapest and the most expensive, and the gap is created by the implant, not by the surgeon's time. Femoral head ostectomy runs USD 1200-2800, GBP 900-2200 or CNY 3000-8000 per side. Cruciate repair runs USD 2500-5000, GBP 2000-4200 or CNY 6000-15000. Total hip replacement runs USD 5000-9000, GBP 4000-7500 or CNY 15000-35000. Every figure below is a range, and the same operation moves 1.5-3x between regions.
3 procedures, 3 different bills
Femoral head ostectomy. The head and neck of the femur are removed, and a false joint forms from scar tissue over 8-12 weeks. It takes 60-90 minutes, needs 1-2 nights of hospital care, and has no implant, which is why it is the cheapest of the 3 and the one most often done when the hip is damaged beyond repair.
Cruciate repair. A torn cranial cruciate ligament is stabilised either with an osteotomy that changes the tibial angle or with an extracapsular suture. Surgery runs 90-120 minutes, plus 1-3 nights. The implant and the saw guide add USD 400-1500 to the surgical fee, and that single line is most of the difference between a 2500 quote and a 5000 one.
Total hip replacement. A cemented or cementless cup and stem replace the joint. It takes 2-3 hours, needs 3-5 nights, and carries an implant cost of USD 1500-4000 alone. It is also the only 1 of the 3 that requires a CT scan in most hospitals, at 400-900, before the implant size is ordered.
The 3 procedures priced in 3 regions
| Procedure | US (USD) | UK (GBP) | China (CNY) | Surgery time, nights |
|---|---|---|---|---|
| Femoral head ostectomy | 1200-2800 | 900-2200 | 3000-8000 | 60-90 min, 1-2 |
| Cruciate repair, one side | 2500-5000 | 2000-4200 | 6000-15000 | 90-120 min, 1-3 |
| Total hip replacement, one side | 5000-9000 | 4000-7500 | 15000-35000 | 2-3 h, 3-5 |
| Implant and guide, cruciate | 400-1500 | 350-1200 | 800-3000 | billed inside |
| CT before THR | 400-900 | 350-800 | 600-1500 | 20-40 min |
| Rehab, 6-12 sessions | 240-1080 | 200-900 | 600-2400 | 30-45 min each |
Across the table the spread from 240 to 35000 is real but it is a spread across procedures. Within one row, the regional difference is 1.5-3x, and it is narrowest on the implant line, because a titanium stem costs the same wherever it is implanted. It is widest on the hospital nights and the surgeon's fee, which track local labour.
What the surgical fee excludes
Rarely is the quoted fee the total. Pre-anaesthetic bloodwork adds 100-250, radiographs 150-400, and a CT 400-900 if the hospital requires one. Anaesthesia is sometimes a separate 250-600, sometimes bundled. Hospital nights run 150-450 each, so the 3-5 nights after a total hip replacement add 450-2250 before any complication.
Rechecks at 2, 6 and 12 weeks add 40-100 each, and physiotherapy adds 40-90 per session across 6-12 sessions. A cat that needs a second side staged 8-12 weeks later faces the surgical fee again, though most hospitals quote the second side 10-20% lower because the imaging and workup do not repeat.
Why cats are not small dogs on this bill
Cat joint surgery is priced differently for 3 reasons. Size: a 4-5 kg cat needs a smaller implant, and the smallest available sizes carry a premium rather than a discount. Bone: cats have thinner cortices, so a cruciate repair that works in a 30 kg dog needs different fixation, and the revision rate for the wrong technique is what drives the second operation. Handling: a cat that will not tolerate 6 weeks of leash rest needs a 10-14 day confinement plan and often a 4-6 week recheck window instead of the 8-12 weeks used in dogs.
The diagnostic path is also more expensive per kilogram. A cat with a limp that will not localise needs radiographs at 150-400, and often a CT at 400-900, because the lesion may be in the hip, the stifle or the spine. That 550-1300 of imaging is spent before a surgical fee is quoted, and it is not refundable if surgery turns out to be the wrong answer.
4 lines that appear after the operation
- An implant removal or a revision within 12 months: 800-2500, and the most expensive single event in the whole episode.
- A 10-14 day wound check plus staple removal: 30-80, occasionally bundled.
- Pain management at home for 7-14 days, dispensed by the hospital: 40-150, priced by weight and duration.
- A 6-8 week recheck with repeat radiographs: 150-400, the visit that decides whether the second side gets done.
Choosing between the 3 on cost alone fails
The 3 procedures are not interchangeable. Femoral head ostectomy at 1200-2800 suits a cat with a fractured femoral head or a hip that cannot be salvaged, and it works because a cat's small body mass lets a false joint carry the load. Cruciate repair at 2500-5000 preserves the joint surface and is chosen when the ligament is the only problem. Total hip replacement at 5000-9000 is reserved for a cat with severe hip disease and a owner prepared for 3-5 nights and 12 weeks of restriction.
A quote that offers the cheapest of the 3 for a problem the other 2 exist to solve is not a saving. The right comparison is 2-3 estimates for the same named procedure, with the implant brand, the nights and the recheck schedule written down, which is the same discipline described at the emergency surgery price list.
Where the money goes over 12 months
For a cruciate repair, the 12-month total is 2500-5000 for surgery plus 150-400 of imaging, 450-1350 of nights, 240-1080 of rehab and 120-300 of rechecks, so 3400-8100 in the US. A joint supplement given for a year adds 150-600, and that line is priced separately at the yearly joint supplement cost. The same episode in China totals CNY 7000-21000 at the low end of each band, and the 1.5-3x regional spread holds at the total as well as at the line.
Insurance and payment structure change the timing rather than the total: 6 instalments across 3400-8100 is a different monthly number from 1 payment, and the cost estimator returns the same 3 bands the hospital quotes.
3 numbers belong in the record before the cat is discharged: the implant lot number if there is one, the date of the last radiograph, and the weight at discharge. Those 3 lines cost nothing and answer the first 4 questions any later clinician will ask.
Frequently asked
Is the cheapest joint surgery always femoral head ostectomy?
It is the cheapest at 1200-2800 in the US, but it is also irreversible: the femoral head is removed and a false joint forms over 8-12 weeks. It suits a fractured head or an unsalvageable hip, not a stable joint with 1 torn ligament, where a 2500-5000 cruciate repair preserves the surface. Comparing the 2 on price alone answers the wrong question, since the operations treat different problems.
What does a total hip replacement include for 5000-9000?
The implant alone is 1500-4000, and the CT required to size it adds 400-900. The fee covers 2-3 hours of surgery, 3-5 nights at 150-450 each, and the discharge radiographs. Bloodwork at 100-250 and rehab at 40-90 per session across 6-12 sessions sit outside most quotes. A second side staged 8-12 weeks later is usually quoted 10-20% lower because the imaging does not repeat.
Why is the same operation 3 times cheaper in another country?
The implant costs close to the same everywhere, so the gap sits in the surgeon's fee and the hospital nights, which track local labour. Within one row of the price table the regional spread is 1.5-3x, narrowest on implants and widest on 3-5 nights of care. Moving a cat abroad for surgery adds travel, a 4-6 week recheck problem and no implant warranty, which is why the comparison rarely closes on price alone.
