Total Knee Replacement

Total Knee Arthroplasty — When knee pain is severe, an artificial joint may be an option

When knee osteoarthritis has progressed and conservative treatment no longer relieves the pain, surgery may be considered.
The damaged joint surface is replaced with artificial parts made of metal and polyethylene.
The goals of surgery are pain relief, restoring knee function, and improving quality of life.
An artificial knee joint typically lasts about 15-20 years, and many patients are able to return to comfortable daily living.

1
Examination and imaging to determine if surgery is needed

X-rays and MRI are used to assess the joint condition and decide if surgery is appropriate

2
Overall health assessment and preparation

Cardiovascular and general health are checked to ensure safe surgery

3
Surgery (artificial joint placed under anesthesia)

The damaged joint surface is removed and artificial joint parts are precisely installed

4
Post-surgery rehabilitation for functional recovery

Rehabilitation begins the day after surgery, gradually restoring walking ability

Most patients see improved walking and quality of life after surgery

Surgical techniques and artificial joint materials continue to improve each year, with better durability. When considering surgery, we evaluate the disease stage, age, activity level, and any other health conditions. Surgery is considered only after conservative treatments have been fully tried.

💡

Our clinic provides pre-surgery evaluation and post-surgery follow-up.
The knee replacement surgery itself is performed at a specialized hospital, but we handle pre-surgery examinations, imaging, conservative treatment, and post-surgery rehabilitation and follow-up at our clinic. Please feel free to consult us about whether surgery might be right for you.

💡 Key Points for Your Decision

  • First, try conservative treatment (rehabilitation, injections, medication) thoroughly
  • The timing of surgery matters — not too early and not too late
  • Do not decide based on age alone — consider how much your daily life is affected
  • If you are unsure, come talk to us. We will help you find the best option together
