Unicompartmental Total Knee Arthroplasty
The normal knee joint has three compartments – the medial, the lateral and the patello femoral. In young patients with early arthritis only one of the compartments may be involved. For eg. Involvement of only the medial compartment in early osteoarthritis of the knee. In such cases it is possible to do a unicompartmental knee arthroplasty in which only one compartment is replaced as against the total knee or tricompartmental knee arthroplasty.

The unicompatmental knee arthroplasty is routinely done at Sancheti Institute of Orthopaedics and Rehabilitation.
Advantages
Ideal for younger patients
High success rate
Earlier recovery of function
Earlier discharge from hospital and return to work
Less pain and less blood loss
Preservation of knee ligaments (cruciates) thereby achieving more normal knee function
Preservation of bone stock
Easier revision to total knee arthroplasty at a later date
   
Disadvantages
The only major disadvantage is that only few patients meet the criteria for a unicompartmental knee arthroplasty.
Recovery
The patient is able to walk on the next day of surgery
Within 24 to 48 hours the patient can raise his/her leg and bend the knee beyond 70 0.
The patient is able to climb stairs within 4 days of surgery
Computer assisted Knee Arthroplasty
     
The success of a total knee arthroplasty depends upon the accuracy of the placement of the components. In computer assisted surgery (CAS), probes are placed on the patient which transmit information to the computer via infrared rays. The computer then guides the surgeon to take accurate cuts and place the components precisely.

At Sancheti Institute of Orthopaedics and Rehabilitation, we are regularly performing computer assisted knee replacements.
Advantages
CAS increases the precision and accuracy of total knee replacement surgery
It eliminates the need of intramedullary jigs, thus decreasing blood loss and the risk of pulmonary embolism
It helps the surgeon to avoid errors in technique that could have an adverse effect on prosthesis survival.
As the computer improves the surgeon’s visualization, it enables the use of minimally invasive techniques thus decreasing pain and improving recovery
