The human knee is made of 3 parts: medial, lateral, and patellofemoral. Unicondylar knee replacement which is also known as partial knee replacement means to rearrange the injured or bad part of the knee which is known as resurfacing in medical term.

Reduced damage to bones, lesser pain, shorter hospital stay

 More ease of mobility

 Better restoration of physiological gait pattern

• Any joint replacement surgery has a risk of developing deep vein thrombosis and/or infection. Generally, complications after UKR are comparatively lesser than that of TKR.

UKR is suitable for patients over 40 years of age. 

Most of the patients are being discharged the same day of the surgery; however, a hospital stay of two to three days may be required in some patients. Patients are able to walk quickly after the surgery. Recovery from the surgery takes typically six to eight weeks.

In most cases, the damage to the cartilage of the knee (due to arthritis) begins from the medial part which later on extends to the lateral part and the patellofemoral side. Replacement of the medial joint at the right time ceases the progression of arthritis.

There are 2 types:

 1. Fixed bearing implants: the tibial insert is fixed to the metal tibial implant and the femoral component rolls on this cushioned surface. It allows the patient to bend and stretch the knee, but not to rotate it normally.

 2. Mobile bearing implants: mobile bearing implants are developed as an alternative to fixed bearing implants to reduce wear and improve range of motion.

 We use mobile bearing implants in all our UKR surgeries.

It is a misconception that UKR is an interual surgery. The success rate of unicondylar/partial knee replacement is the same as total knee. Replacement. Long-term research done by oxford on partial knee replacement showed remarkable results of the clinical study depicting survivorship of 94.0% at 15 years and 91.0% at 20 years in the patients.

TKR requires removal of at least one ligament of the knee whereas UKr does not require removal of any ligament.

UKR saves up to 75% of the healthy tissues of the compound knee joint.

incision during the surgery of UKR is almost half than that of TKR, also there is no muscle incision in UKR.

only 3 days of hospital stay in UKR.

knee prosthesis can be made of stainless steel, cobalt-chromium alloys, titanium alloys, polyethene, girconium etc. 

These are designed to facilitate friction-less movements between two surfaces of the knee.

Partial knee replacement benefits those patients with arthritis whose only medial part of the knee is affected. This surgery is contraindicated in patients having rheumatoid arthritis or gout.

Most of the patient are able to ride a bicycle, swim, and play tennis, however, they should avoid contact sports. The patients are also able to climb stairs and sit crosslegged after the surgery. our ukr surgeries.
