Understanding the anatomy of a knee joint

The knee joint is a complex hinge joint that connects the thigh bone (femur) to the shinbone (tibia). It consists of three main compartments: the medial compartment, the lateral compartment and the patellofemoral compartment.

The ends of the bones are covered with smooth cartilage, which facilitates smooth movement and acts as a shock absorber. Ligaments provide stability to the joint and the muscles surrounding the knee joint enable movement and support. Understanding the anatomy of the knee joint is crucial for comprehending the purpose and benefits of robotic knee replacement surgery.

What is robotic knee replacement?

Robotic knee replacement is a surgical technique that combines the expertise and knowledge of an orthopedic surgeon with the precision and guidance of automated technology. During the procedure, the surgeon utilizes a robotic system that assists in planning and executing the surgery with high accuracy.

The surgeon controls the robotic arm and provides real-time feedback, allowing for precise bone cuts, implant positioning and ligament balancing. This technology enhances the surgeon's ability to achieve optimal alignment and balance, improving outcomes and patient satisfaction.

Types of robotic-assisted knee replacements

The following are the different types of robotic-assisted knee replacement surgeries. It’s important to acquaint yourself with each one to know which one would be the most suited for you and what to expect.

Robotic total knee replacement

Robotic total knee replacement involves replacing the entire knee joint with artificial components. It is typically performed for patients with extensive damage or arthritis affecting the entire knee joint.

Robotic partial knee replacement

Robotic partial knee replacement, also known as unicompartmental knee replacement, involves replacing only the affected compartment of the knee joint. It is suitable for patients with localized knee joint damage, usually limited to one compartment.

Robotic unicompartmental knee replacement

Robotic unicompartmental knee replacement is a variation of partial knee replacement that focuses on replacing a single compartment of the knee joint. It is a minimally invasive option for patients with isolated compartmental knee joint damage, offering faster recovery and preservation of healthy tissues.

Indications for robotic knee replacement

If you are suffering from any degenerative knee diseases like osteoarthritis, then robotic-assisted knee replacement is indicated. It’s possible for your doctor to recommend surgery if you have undergone non-surgical treatment options but failed to relieve your symptoms.

Age and activity level

Robotic knee replacement can benefit patients of various ages, but surgeons typically recommend it for individuals who have experienced a decline in knee joint function and are experiencing pain and limited mobility. Doctors also consider activity level, as it can impact the long-term success of the surgery.

Severity and localization of joint damage

The extent and location of the knee joint damage are crucial factors. Robotic knee replacement can be a solution for patients with moderate to severe joint damage that affects the quality of life and is unresponsive to conservative treatments.

Body weight and BMI

Patients with higher body weight or BMI may be at increased risk during surgery and during the recovery period. The surgeon will assess these factors and discuss the potential risks and benefits of robotic knee replacement accordingly.

Joint deformity and alignment

Robotic knee replacement can correct joint deformities and improve alignment. Patients with joint deformities or misalignments that cause pain or instability may be candidates for this surgical approach.

Muscular strength and flexibility

The strength and flexibility of the muscles around the knee joint are essential for successful recovery. Patients with adequate muscular strength and flexibility generally have better surgical outcomes and are suitable candidates for robotic knee replacement.

Common knee conditions treated with robotic surgery

Robotic-assisted joint replacement surgery has successfully addressed various knee conditions. With the precision and customization offered by robotic technology, our surgeons can effectively treat the following conditions:

  1. Osteoarthritis: The most common form of arthritis, characterized by the degeneration of joint cartilage over time.

  3. Post-Traumatic arthritis: Arthritis that develops after a knee injury or trauma, leading to joint degeneration.
  4. Degenerative joint disease: A general term for the progressive loss of cartilage in the knee joint, resulting in pain and limited mobility.
  5. Failed previous joint replacement: Individuals who have undergone a previous knee replacement surgery may require a revision procedure due to implant failure or complications.
  6. Corrective surgeries for joint deformities: Robotic-assisted surgery can help correct knee deformities like bowlegs or knock knees.
  7. Revision surgeries for implant failure: In cases where a previous knee replacement has failed, robotic-assisted surgery can be used to revise or replace the implant.
  8. Complex joint conditions: Some knee conditions, such as severe deformities or complex cases, can benefit from the precision and customization offered by robotic-assisted surgery.
  9. Other knee disorders: Robotic-assisted joint replacement can be used to treat various other knee disorders, including cartilage damage, meniscal tears, and ligament injuries.
