Robotic Total Knee Replacement for Severe Valgus Deformity

Severe knee deformities can take away more than just mobility — they affect independence, confidence, and quality of life. At MIOT International, advanced robotic-assisted total knee replacement surgery is transforming outcomes for patients with even the most complex knee conditions.

This case study highlights the successful treatment of a 63-year-old patient with severe valgus knee deformity, demonstrating how robotic precision, expert surgical planning, and personalised care can restore alignment, stability, and pain-free movement.

Understanding Severe Valgus Knee Deformity

Valgus knee deformity, commonly referred to as an “X-shaped leg”, occurs when the knee bends inward while the lower leg points outward. In severe cases, this condition can be disabling.

Clinical Presentation in This Case

• Knee angulation of 32 degrees inward
• Severe joint wear and tear
• Marked difficulty in walking and standing
• Progressive pain and swelling
• Altered posture leading to back pain
• Increased risk of falls and further joint damage

Such advanced deformities are technically challenging to manage using conventional knee replacement techniques.

Prior to intervention, the patient experienced:

• Persistent pain and swelling
• Difficulty walking even short distances
• Reduced mobility and balance
• Muscle strain and fatigue
• Inability to stand for prolonged periods
• Progressive loss of confidence in daily activities

Conservative treatments were no longer effective, making surgical correction essential.

Why Robotic Total Knee Replacement Was Chosen

In complex deformities, precision is critical. Robotic-assisted knee replacement allows
surgeons to:

• Plan surgery in three dimensions
• Correct deformity with millimetre-level accuracy
• Balance ligaments in real time
• Restore natural knee alignment safely and predictably

At MIOT, robotic technology enables surgeons to address deformities that would otherwise carry a higher risk of imbalance or early implant failure.

Key Advantages

• Greater range of knee motion after surgery
• Less pain compared to conventional methods
• Reduced blood loss
• Shorter hospital stay
• Faster functional recovery
• Lower cardiopulmonary complication risk
• No mandatory pre-surgery CT scans, avoiding additional radiation exposure

The robotic system acts as a precision tool guided by the surgeon, ensuring accuracy without replacing clinical judgement.

Surgical Outcome

Using robotic-assisted total knee replacement:

• The knee deformity was completely corrected
• Proper limb alignment was restored
• No residual deformity remained after surgery
• Implant positioning achieved optimal balance and stability
