About this trial

This is an interventional treatment trial for Osteoarthritis

Eligibility Criteria

20 Years - 100 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Include all patients who are surgical candidates for primary TKA with unilateral osteoarthritis
  • All eligible male or female patients between the ages of 20 years to 100 years old
  • All included study participants must be able to give an informed consent.

Exclusion Criteria:

  • Significant femoral or tibial deformity due to congenital or traumatic etiologies, inflammatory arthritis, post-septic arthritis, osteomyelitis, prior infection of knee joint, osteoporosis, dislocated or fragmented patella
  • The presence of infections, highly communicable diseases (e.g. AIDS), active tuberculosis, venereal disease, hepatitis.
  • Significant neurological or musculoskeletal disorders or disease that may adversely affect normal gait or weight bearing.
  • Presence of previous prosthetic knee replacement devices (of any type)
  • Metastatic disease
  • Psychiatric illness
  • Drug or alcohol abuse
  • Body mass index (BMI) > 40 kg/m2

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Total Knee Robotically-Assisted

Total Knee Manual-Executed by Surgeon

Arm Description

The intervention is then performed with a new device and surgical procedure. At first the femur and the tibia are fixed to the operating table with a special clamp and the knee bones are exposed with the standard technique; then the surgeon digitizes the shape of the joint and the computer transfers the planned surgical strategy to a dedicated surgical robot. Resections are performed by the surgeon on a constrained guide held by the robot.

Your orthopaedic surgeon will remove the damaged cartilage and bone, and then position the new metal and plastic implants to restore the alignment and function of your knee.

5. Study Description

Brief Summary
This study will explore if there are any difference in functional outcomes between two different surgical procedures for total knee replacement: robot-assisted versus manually-executed total knee arthroplasty.
Detailed Description
Although total knee arthroplasty (TKA) is an effective treatment for end-stage knee arthritis, improvements in surgical technique remain a necessity. Contemporary designs have bolstered durability, but longer life expectancies have placed an even greater emphasis on survivorship. Additionally, patient satisfaction remains an issue. A prospective randomized clinical trial (RCT) is proposed to compare robotically-assisted versus manually executed primary (TKAs). This study is designed to address the major short-term clinically important issues between the two types of procedures with special emphasis on functional outcome. Patients will be randomized to receive either a robotically-assisted or a manually-executed primary TKA.
