ROBOTIC TKR ( Knee Replacement)

What Is Robotic Knee Surgery?

Robotic surgery does not mean that an actual robot performs the entire surgery. Instead, doctors use a robotic surgical arm to execute parts of the procedure, assisting in areas that demand the steadiest hand and navigating small places. Robotics becomes another tool in the doctor’s kit , it helps in

• Prepare the bone.

• Introduce the implant.

• Balance the implant.

• Check for the right fit.

Who is a Candidate for Robotic Knee Replacement?

If you are a candidate for traditional knee replacement, it is likely you are a candidate for robotic-assisted knee replacement, as well. I

Robotic knee replacements are ideal for even the most complex knee joint disease. This includes patients who have:

• Deformities in the femur after an injury

• Complex degeneration

• Hardware from previous surgeries

what are the advantages of robotic knee replacements ?

several advantages of robotic-assisted knee replacement surgery when compared with traditional surgery. Advantages include:

• Enhanced surgical planning. Depending on the robotic option that is right for you, specialized 3-D images are taken in preparation for or during surgery. These images help your surgeon more accurately plan the optimal type and placement of your replacement joint to ensure the right size and fit.

• Greater precision. Robotic technologies enhance your orthopaedic surgeon’s expertise for more precise planning, tissue removal and implant placement. This can cause faster recovery times, fewer complications and a lower likelihood of revision surgery.

• More ligament-sparing options. With the added precision and accuracy from the robotic-assisted knee replacement system, ligament-sparing total knee replacement surgery is available to more patients than ever before.

What is the recovery period after a Joint Replacement surgery ?

With the evolution of quality of fixation ,quality of implants (Us/Eu - IMPORTED ) and confidence of surgeons(specifically trained for joint replacement surgery), there is no 'bed-rest' after Joint Replacement surgeries now-a-days.

The patient gets moving the day after the surgery, with the aid of a walker. Bedside exercises are taught by the physiotherapist, and by the time of discharge 5-7 days after the surgery, the patient is relatively pain-free, and can carry out his day-to-day activities without any assistance. Some kind of walking aid is continued for 6 weeks after surgery. It takes 3 months to gain adequate strength, and normal gait after the surgery.

When does a patient stand and when will he walk after knee replacement surgery ?

Patient stands on the second day and walks with a walker on 2/3 rd day .

What is the duration for which any kind of support is required ?

A walker is used for two -three weeks followed by a cane for another 2-3 weeks , followed by walking without any support.

Should we get a bilateral or staged unilateral knee replacement ?

If the patient is young 65 , minimal comorbidties a simultaneous knee replacement is done , other wise a staged knee replacement with a gap of three months is advised and safe .

What is the anaesthesia ?

Usually spinal with epidural anaesthesia is advised for prolonged postoperative pain control.

What is the time taken for surgery ?

Straight forward knee

30 min - anaesthesia induction

90 min- surgical time

30 min - post op

Diffficult knee - UPTO 2 HOURS SURGICAL TIME

WHAT WILL BE THE POST SURGERY PAIN RELIEF MEASURES?

Post surgery 2- 3 days will be taken care by epidural anaesthesia and analgesic coverage(2 weeks) to give you a very good painless period and recovery .

Success rates of knee replacement surgery - Success rates and quality of life improvements for knee replacement patients are reliably very high. Nine out of 10 knee replacement patients experience an immediate relief from knee pain, and 95% report they are satisfied with their procedure. Approximately 90% of replacement knee joints last 10 years, while 80% are good for 20+ years, depending on patient health and activity levels.

Outcomes vary from patient to patient
