Minimally Invasive Total Knee Arthroplasty
關節炎晚期,包括骨關節炎、類風濕性關節炎、痛風性關節炎、外傷性骨關節炎以及自發性膝骨壞死,可能因為疼痛、關節積液、變形以及活動範圍受限,而導致嚴重的功能障礙。
全膝關節置換手術可以提供新的、平滑的關節面(關節表面重建)並矯正患肢的變形(重新對線),是骨科領域中最令人滿意的手術之一。
🦵 Minimally Invasive Surgery
Minimally Invasive Total Knee Replacement (MIS-TKR) is a joint reconstruction surgery designed to minimize incision size, reduce postoperative pain, and accelerate recovery. Compared to traditional total knee replacement, MIS uses smaller incisions and specialized instruments to more precisely replace the damaged joint while preserving more of the tendons, ligaments, and soft tissues.
🛠 Surgical Procedure and Features
The average duration of a minimally invasive total knee replacement is less than 30 minutes for a single knee and under 70 minutes for bilateral procedures. The incision size is typically around 8 to 10 cm. More importantly, compared to traditional methods, this technique causes significantly less trauma to the quadriceps muscle, meaning most patients do not require walking aids after surgery.
🩸 Multimodal Blood Management
Our standardized protocols include intra-articular medication injections to reduce blood loss, along with postoperative blood transfusion planning. Even for simultaneous bilateral knee replacements, patients can recover safely and comfortably.
💊 Multimodal Pain Management
We utilize a combination of oral medications, intravenous injections, and patient-controlled analgesia (PCA). This significantly enhances early rehabilitation and patient satisfaction. With this approach, nearly all patients are able to walk on the first day after surgery.
🛡 Prevention of Venous Thromboembolism (VTE)
VTE is a known complication after total knee replacement, but it is effectively preventable. Our preventive regimen includes low molecular weight heparin (LMWH), low-dose aspirin, and Factor Xa inhibitors to reduce the risk of thrombosis.
🧑⚕️ Professional Rehabilitation Program
Team of experienced orthopedic surgeons, physiatrists, physical therapists, and nurse specialists support patients through a comprehensive rehab plan. This includes:
-
Continuous Passive Motion (CPM) therapy
-
Cold therapy (icing)
-
Assisted walking and stair training
-
Education and support for postoperative recovery
🧑⚕️ Indications (Who is a Candidate?)
-
Severe osteoarthritis
-
Rheumatoid arthritis
-
Loss of knee function interfering with daily activities (e.g., climbing stairs, walking)
-
Chronic knee pain unresponsive to medication
🔧 Step-by-Step Procedure
-
Accurate Evaluation
X-rays or MRI are used to assess knee joint damage before surgery. -
Small Incision Entry
A small anterior incision of about 8–12 cm is made over the knee. -
Tissue Preservation
Specialized instruments help avoid damage to key tendons and ligaments. -
Removal of Damaged Bone
Diseased joint surfaces and deformed bone are carefully excised. -
Implantation of Prosthesis
Metal and polyethylene prosthetic components are installed. -
Closure and Recovery
With a smaller wound and less trauma, patients often begin walking shortly after surgery.
🌟 Key Benefits
-
Smaller, more cosmetically appealing scar
-
Less blood loss, reduced need for transfusion
-
Milder postoperative pain and quicker recovery
-
Shorter hospitalization and earlier return to mobility
-
Ideal for elderly patients or those seeking rapid return to function
⚠️ Important Notes & Potential Risks
-
Not all patients are suitable for MIS—those with severe deformities or prior knee surgeries may require traditional methods
-
Regular postoperative rehab is essential to restore mobility and strength
-
Rare risks include infection, blood clots, prosthetic loosening
-
Surgeon experience and hospital equipment are key to successful outcomes
🎯 Ideal Candidates
-
Younger or more active individuals
-
Moderate-to-severe joint degeneration without major deformity
-
Those aiming for rapid return to work and daily life
