Our Summary

The success of total knee replacement surgery (also known as total knee arthroplasty or TKA) relies on restoring the stability and effective movement of the original knee. The introduction of robotic surgical technology has significantly improved the exactness and consistency of these procedures. This research paper discusses recent robotic TKA systems, looking at the features of the different platforms, their accuracy, and the results for patients. Initial findings suggest patients are benefiting significantly, but we are still waiting for long-term evidence from large-scale clinical trials. Furthermore, improvements in this technology need to be made to address looseness in the knee while tailoring the performance of each patient’s new joint to their individual needs.

Doctor’s Tip

A helpful tip a doctor might tell a patient about knee replacement is to follow the post-operative rehabilitation plan carefully. This may include physical therapy exercises to improve strength and range of motion, as well as advice on gradually increasing activity levels. Adhering to the rehabilitation plan can help ensure a successful recovery and optimal long-term outcomes following knee replacement surgery.

Suitable For

Patients who are typically recommended for knee replacement surgery are those who have severe knee pain and stiffness that limits their daily activities, have not had success with conservative treatments such as medication or physical therapy, have significant joint damage from conditions such as osteoarthritis or rheumatoid arthritis, and have failed to find relief from other surgical procedures such as arthroscopy. Additionally, patients who have a stable and well-functioning knee joint prior to surgery are more likely to have successful outcomes with knee replacement.

Timeline

  • Patient experiences knee pain and limited mobility due to osteoarthritis or other conditions
  • Patient consults with orthopedic surgeon and undergoes pre-operative evaluations and tests
  • Patient undergoes knee replacement surgery with robotic assistance for increased precision and accuracy
  • Post-surgery, patient goes through rehabilitation and physical therapy to regain strength and mobility
  • Patient experiences reduced pain and improved function in the knee
  • Over time, patient continues to see improvements in mobility and quality of life as the knee heals and strengthens.
