Minimally Invasive Total Knee Arthroplasty

Feature Summary

        The advantages of minimally invasive total knee arthroplasty include a smaller wound size with better cosmesis, less damage of thigh muscle (quadriceps, vastus medialis) to facilitate early recovery without the need of walking aids.



        Advanced stage of arthritis including osteoarthritis, rheumatoid arthritis, gouty arthritis, traumatic osteoarthritis and spontaneous osteonecrosis of the knee can lead to severe functional impairment because of pain, joint effusion, deformity and limited range of motion. Total knee arthroplasty surgery can bring to a new, smooth articulating surface(resurfacing) as well as to straighten the affected leg (realignment), which is one of the most satisfying surgery in the field of Orthopedics.


Procedures and Features

  • Minimally invasive surgery

        Mean operation time of minimally invasive total knee arthroplasty would be around 30 minutes only or less; simultaneous bilateral total knee arthroplasty would take around 70 minutes or less. Wound size would be approximately 8 to 10 centimeters. More importantly, we do less damage to quadriceps muscle during the surgery, compared with traditional surgical approaches. Therefore, walking aids after surgery are usually not required.


  • Multimodal patient blood management

        We have standard protocol including intra-articular medication to reduce blood loss as well as post-operative blood transfusion, which makes patients safe and comfortable even undergoing simultaneous bilateral total knee arthroplasty.


  • Multimodal pain control management

        Combined oral, intra-venous or patient-controlled analgesia devices greatly facilitate early rehabilitation and patient satisfaction. Almost all patients can walk well on post-operative day 1 with our pain management.


  • Venous thromboembolism prevention protocol

        VTE (venous thromboembolism) is one of the common complications following total knee arthroplasty, but can be well prevented. Combination of intravenous low molecular weight heparin, low dose aspirin, factor Xa inhibitor in our protocol can effectively protect against this complication.


  • Professional rehabilitation program

        Our team, composed of experienced orthopedic doctors, rehabilitation doctors, physical therapists, special nurses can help patients with their post-operative rehabilitation protocol, including continuous passive range of motion exercises with machines, ice-packing, walking independently with or without walking aids, walking up- or downstairs and to deal with common questions after surgery.


Estimated cost

        The procedure cost is around 400,000 NTD, depends on the actual medical expenses.
