Partial Knee Replacement relieves 58-year-old
patient from chronic pain

A 58-year-old patient with complaints of a severe medial aspect of knee joint pain, persistent for the past 2 years, was brought to Nanavati Super Speciality Hospital. His pain aggravated while walking and felt relieved after taking rest. His disability had progressively intensified in the past 2 months. A detailed clinic-radiological assessment confirmed a Medial Uni-compartmental Osteoarthritis. Consequently, he was recommended for a Partial Knee Replacement (Medial UKR). An expert team at the Specialised Joint Replacement OT at Nanavati Super Speciality Hospital successfully performed a Partial Knee Replacement (Oxford Mobile bearing UKR) on him. As per the routine protocol, he was able to walk on the same day of the surgery after an interval of 7 hrs. After 15 days post the operation, the patient is pain-free and has regained near-normal activity level including sitting on the floor.

Knee Replacement is one of the best options available for Arthritis of the knee when it comes to excellent functioning, correction of deformity and providing stability. However, when only a single compartment of the knee is arthritic, it is possible to replace the single compartment preserving both the Anterior and Posterior Cruciate Ligaments (ACL & PCL) unlike Total Knee Replacement (TKR) where the ACL is absent, and PCL is sometimes sacrificed.

Subsequently, for people in the age group of 50 to 70 years with younger symptomatic knee Arthritis where only the single compartment gets destroyed by a degenerative process with pain as the main symptom, this technique is popularised with refined modern technology. With adequate pre-operative planning in a select patient group, Uni-compartmental Knee Replacement (Partial Knee Replacement) provides the best functional results. It offers excellent pain relief, and because the ACL & PCL are preserved in this technique, it also maintains near normal knee kinematics and functions.

"Partial Knee Replacement surgery is performed to replace only one part of a damaged knee. It can replace either the inside (medial) part, the outside (lateral) part, or the kneecap part of the knee." 1

Partial Total Knee Replacement needs good pre-operative planning, exacting indication and extremely precise surgical technique. It is a highly demanding and rewarding surgery. The partial knee does not offer correction of knee deformity and therefore is not recommended if the deformity is more than 15 degrees. Likewise, it is not advised in advanced arthritis and also for stiff knees.
