Partial knee replacement simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement.

Osteoarthritis, the most common type of arthritis is a degenerative joint disease in which the joint cartilage gradually wears away. As a result bones rub together resulting in extreme pain. The knee can be divided into three compartments:

  • Patellofemoral – the compartment behind the kneecap

  • Medial compartment – the compartment on the inside of the knee

  • Lateral compartment – the area on the outside of the knee joint


What are the advantages of ConforMIS over traditional implants?

ConforMIS® has developed the personalized knee resurfacing implants with unique advantages against traditional knee replacement options. To design a personalized implant for every individual, surgeon will perform the CT scan of the affected knee of the patient. A 3D image of a patient’s knee is created from CT scans and an implant is designed to conform exactly to individual size and shape.

  • No compromise on the size of the implant as is patient specific

  • Provides better fit of the implant as the implant conforms to the patient’s unique shape of the articulating surfaces of the knee joint

  • Maximizes the implants contact area decreasing the polyethylene contact stress thereby prolonging the life of the implant

  • Preserves more natural bone

  • Maximizes proximal tibial coverage and thus reduces the risk of tibial implant caving in and loosening
