Ultra-Precision Robotic Knee Replacement Surgery & Core Medical Technologies

Knee replacement surgery (Total Knee Replacement, TKR) is performed over 100,000 times annually in South Korea, making it one of the most common orthopedic procedures. In recent years, robotic-assisted surgery has grown rapidly thanks to advancements in medical technology — and Wellton Hospital is at the forefront of this evolution.

Wellton Hospital performs Minimally Invasive Robotic TKR (MIS Robot TKR) — completed through a single, minimal incision — offering patients optimal outcomes with faster recovery and fewer complications.

🤖 Advanced Robotic Technology: VELYS System

Wellton Hospital uses the VELYS Robotic-Assisted Solution developed by Johnson & Johnson, a world-class medical technology company. Designed specifically for knee joint surgery, this system delivers precision that leaves zero room for error.

400 fps

Ultra-precise measurement

A high-performance camera analyzes 400 frames per second, measuring joint gap and angle to within 0.5 mm and 0.5° — ensuring only the exact amount of bone needed is reshaped.

100%

Surgeon-led precision

The surgeon remains in full control throughout the procedure, analyzing data and guiding every step — the robot augments skill, it doesn't replace it.

 

⚖️ Perfect Knee Balance: Preventing Complications

One of the most critical factors in a successful knee replacement is achieving the correct balance across the joint.

3D Balance Alignment

Not only is left-right alignment corrected to prevent O-leg or X-leg deformity — the system also perfectly matches flexion and extension balance, ensuring natural movement after surgery.

Pre-operative simulation

Before any bone is cut, the robot checks ligament tension in real time and simulates the optimal resection plan. This prevents post-operative stiffness or joint instability before it can occur.

🏥 Wellton Hospital's 3 Core Technologies for Faster Recovery

When cutting-edge robotics is paired with Wellton Hospital's proprietary surgical expertise, patients return to daily life significantly sooner.

1 Quadriceps muscle preservation technique

Surgical approach

Rather than cutting through the quadriceps (the key muscle at the front of the thigh), the surgeon gently moves the muscle aside to access the joint — preserving its full integrity.

Patient benefit

Since the most important muscle for walking and extending the knee remains intact, patients can stand and walk on the day of surgery — dramatically shortening overall rehabilitation time.

2 Posterior cruciate ligament (PCL) preservation

Surgical approach

The posterior cruciate ligament — one of the key stabilizers of the knee — is retained rather than removed during the procedure.

Patient benefit

Patients experience less of a "foreign body" sensation from the implant, and enjoy notably more stable, natural movement when going up and down stairs.

3 Single-incision robotic surgery — no added cuts, no fracture risk

Surgical approach

Conventional robotic TKR requires additional skin incisions to fix sensor pins to the bone. At Wellton Hospital, pins are secured through the original surgical incision — no extra cuts needed.

Patient benefit

No additional scarring. More importantly, the risk of femoral fracture from forceful pin insertion above the knee is completely eliminated — making this technique safe even for patients with osteoporosis.

A single minimal incision. Muscle and ligament preservation. Robotic accuracy and safety.
MIS Robotic TKR at Wellton Hospital — less pain, faster recovery, and a healthier return to everyday life.
