Orthopedic Surgery

Indications for joint replacement surgery vary depending on the severity of joint pain symptoms. If there is no expected improvement through medication, physical therapy, or exercise therapy, and daily life is significantly affected — or if examinations reveal the progression of arthritis or other related conditions — joint replacement surgery may be considered. However, the appropriate treatment varies depending on the patient's condition, so we recommend a consultation for a personalized assessment.

The length of hospital stay varies depending on individual pain tolerance and recovery progress, but it is typically around 3 to 6 weeks.

Joint replacement surgery is covered by public health insurance in Japan. As a result, patients' out-of-pocket expenses can be significantly reduced by using public healthcare support systems such as the High-Cost Medical Expense Benefit. The scope of eligibility and amount of financial relief depends on factors like income level and insurance type. Please consult us for more detailed information.

In general, most patients can resume everyday activities within 1 to 2 months after surgery. At our facility, rehabilitation begins the day after the operation, and by the time of discharge, most patients are able to perform basic daily tasks. While activities that place significant stress on the joint (such as sitting in a kneeling position or high-impact contact sports) should be avoided, travel and low-impact sports are usually possible.

PRP (Platelet-Rich Plasma) therapy aims to relieve joint pain and reduce inflammation. Although it cannot cure knee osteoarthritis itself, it may help prevent further cartilage damage by suppressing inflammation. At our clinic, regenerative medicine is offered as an alternative option when standard treatments have not achieved satisfactory results. Please note that PRP therapy is not covered by insurance (self-funded) and costs may be high. Like oral medications, treatment effectiveness can vary between individuals.

This treatment is suitable for patients who:
- Have not progressed to the stage where surgery is indicated,
- Are experiencing persistent pain that does not improve with current treatments,
- Prefer to avoid surgery or have difficulties with hospitalization.
Because this therapy places a low physical burden on the body, even elderly patients may be eligible.
