Knee replacement is increasingly one of the treatments international patients consider when looking at medical care in China.

For patients whose osteoarthritis is limited to one part of the knee, unicompartmental knee arthroplasty (UKA) — also known as partial knee replacement — may sometimes be an option instead of total knee replacement.

But for someone considering travelling to China, the important questions are usually much more practical:

How quickly can I walk after surgery? How long will I stay in hospital? What does the operation cost in China? And how long should I remain in China before flying home?

A recent case published by Guangdong Second Provincial General Hospital provides a useful real-world example.

A 72-Year-Old Patient Travels to Guangzhou for Partial Knee Replacement

The patient was a 72-year-old man from the Chaoshan region of Guangdong.

He had significant knee osteoarthritis and had already been considering knee replacement surgery.

However, he had recently undergone hip surgery and spent several months recovering. After experiencing a major joint operation, he was reluctant to undergo a total knee replacement if a less extensive procedure was possible.

He eventually travelled to Guangdong Second Provincial General Hospital in Guangzhou for assessment.

According to the hospital's published case, his knee condition was considered suitable for unicompartmental knee replacement.

Rather than replacing the whole knee joint, the surgeons replaced only the damaged portion.

The hospital reported that the operation took approximately 30 minutes, with estimated blood loss of less than 20 mL.

The patient was able to begin walking the following day and was discharged after approximately 48 hours.

This was one patient's individual recovery experience and should not be treated as a guaranteed outcome for every UKA patient.

What Does Partial Knee Replacement Involve?

UKA replaces only the part of the knee affected by advanced arthritis while preserving more of the patient's remaining bone, cartilage and ligament structures.

This is one reason the procedure is sometimes described in China as a form of “knee-preserving surgery.”

However, UKA is not suitable for every patient with knee osteoarthritis.

If arthritis affects several areas of the knee, or if there are significant ligament, alignment or stability problems, another procedure such as total knee replacement may be more appropriate.

For an international patient, the most useful first step is therefore not simply asking:

“Can I have a partial knee replacement?”

but rather:

“Do my X-rays and medical records show that I am a suitable candidate for UKA?”

A Chinese orthopaedic specialist can usually begin assessing this after reviewing recent imaging and medical records.

What Was Recovery Like in This Case?

The early recovery reported in the Guangzhou case was relatively fast.

The patient began getting out of bed and walking on the day after surgery.

Before discharge, he was able to practise walking with a mobility aid and also practise going up and down stairs.

Approximately 48 hours after surgery, he was discharged from hospital.

This is one of the attractions of partial knee replacement for appropriately selected patients: the operation may involve less tissue disruption than a total knee replacement, allowing some patients to begin rehabilitation relatively quickly.

However, there is an important distinction for international patients:

Being discharged from hospital does not mean being fully recovered or ready to take a long international flight.

The patient may still need walking assistance, wound monitoring, rehabilitation and postoperative follow-up.

How Much Does Partial Knee Replacement Cost in China?

There is no single national price for UKA.

Costs vary depending on the hospital, implant, whether robotic assistance is used, length of admission and the patient's individual treatment needs.

Instead of relying on advertised package prices, we collected several real patient hospital settlement records from major Chinese hospitals.

Real UKA Hospital Bills in China

These figures are individual real-world examples, not fixed quotations from the hospitals.

An overseas patient should request a current estimate based on their own case.

Domestic Implant Cost Examples

Based on these cases, unilateral UKA using a domestic implant cost approximately:

RMB 20,000–32,000 before insurance reimbursement.

That does not mean every hospital in China will charge within this range, but it gives international patients a useful reference based on actual hospital bills.

Rehabilitation Can Add to the Final Cost

The Shanghai Sixth People's Hospital case also demonstrates why the hospital surgery bill may not represent the entire treatment cost.

The patient recorded approximately RMB 56,393.68 in medical expenses associated with the operation and hospital treatment.

The patient subsequently received inpatient rehabilitation at another facility.

When rehabilitation, meals and caregiver services were included, the documented overall treatment-and-recovery expenditure reached approximately:

RMB 93,767.67

This illustrates an important point for overseas patients:

The surgery bill is only one part of the possible total cost.

Rehabilitation, accommodation and personal assistance may also need to be considered.

What Should an Overseas Patient Prepare?

A patient does not necessarily need to travel to China before a Chinese surgeon can begin reviewing whether UKA may be appropriate.

The most useful records are recent knee X-rays, especially weight-bearing X-rays if available, together with MRI if one has already been performed.

Previous orthopaedic reports, records of earlier knee or hip surgery, current medications and information about treatments already attempted — such as physiotherapy or injections — can also be useful.

It is better to provide the original imaging files whenever possible rather than only sending photographs or screenshots of the scans.

The first goal is to allow the specialist to answer a basic question:

Is this patient likely to be suitable for partial knee replacement, or is another treatment more appropriate?

How Long Should an International Patient Stay in China?

The patient in the Guangzhou case left hospital approximately 48 hours after surgery.

Several other real UKA bills we reviewed showed hospital stays of around 3–6 days.

But an overseas patient should not plan to fly home based only on the discharge date.

After leaving hospital, the patient may still need time for wound review, mobility training, rehabilitation, medication adjustment and postoperative review by the surgeon.

Long-distance travel immediately after lower-limb surgery can also raise concerns about blood-clot risk.

For this reason, the appropriate time to fly home should be decided with the treating surgeon based on the patient's actual recovery.

For an international patient, it may therefore be more useful to think of the treatment journey as:

arrival in China → hospital assessment → surgery → hospital discharge → early recovery and follow-up → return home

rather than simply calculating how many nights are spent inside the hospital.

Is Partial Knee Replacement in China Worth Considering?

For patients who have already been advised to consider UKA, China may offer several practical advantages.

Major Chinese public hospitals perform large numbers of joint procedures, and real patient bills show that the cost can vary significantly depending on the implant and technology selected.

From the cases reviewed for this article:

Domestic-implant unilateral UKA was approximately RMB 20,000–32,000.

Cases using imported implants were around:

RMB 50,000 or more.

One imported Stryker case using robotic assistance had a total hospital bill of approximately:

RMB 55,745.

But cost should come after the medical question.

The first step is determining whether the patient's pattern of knee arthritis is actually suitable for partial replacement.

Once that is established, the patient can compare hospitals, surgeons, implant options, estimated costs and recovery arrangements.

Getting a Knee Replacement Assessment in China

China MedCare helps international patients access medical care in China.

For patients considering knee surgery, we can help organize medical records, identify suitable orthopaedic specialists, coordinate hospital appointments and assist with the practical arrangements surrounding treatment.

For patients receiving treatment in Shenzhen, in-person medical concierge support can also be arranged throughout the hospital journey.

China MedCare does not diagnose patients or determine whether UKA or total knee replacement is appropriate. The treatment plan must be determined by a qualified orthopaedic surgeon after reviewing the patient's medical records and imaging.

Case-source note: The main patient story is based on a case published by Guangdong Second Provincial General Hospital. Cost examples are based on publicly shared patient hospital settlement records from the hospitals named above. These are individual historical examples rather than guaranteed current prices.
