Unicompartmental Knee Replacement (UKR), also known as partial knee replacement, involves the resurfacing of a specific segment of the knee, serving as an alternative to total knee replacement for patients with localized knee disease. Due to the utilization of a smaller incision in the UKR procedure, patients typically experience minimal or no hospitalization and a faster return to normal activities compared to total knee replacement recipients.

For cases of advanced osteoarthritis confined to a single knee compartment, unicompartmental knee replacement is a viable treatment option. In this surgical intervention, the damaged compartment is replaced with metal and plastic components, preserving the healthy cartilage, bone, and ligaments.

Orthopaedic Evaluation:

Thorough assessment by an orthopaedic surgeon is imperative to determine the suitability of a patient for a partial knee replacement.

Medical History:

Your physician will inquire about your overall health, knee pain, and functional capabilities before performing your knee replacement surgery.

Location of Pain:

Emphasis will be placed on the specific location of pain. Candidates for partial knee replacement often exhibit pain predominantly on either the inner or outer part of the knee. Total knee replacement may be recommended for those experiencing pain throughout the entire knee or in the front (under the kneecap).

Physical Examination:

A meticulous examination of the knee will be conducted to assess range of motion and ligament integrity. Stiffness or weakness in the knee may disqualify a patient from unicompartmental knee replacement, with total knee replacement remaining a potential option.

Imaging Tests:

  • X-rays: Multiple knee X-rays are ordered to determine the extent of damage and deformity, providing insight into the arthritis pattern.

  • Magnetic Resonance Imaging (MRI) Scans: In certain cases, an MRI scan may be recommended to enhance cartilage evaluation.

Before Partial Knee Replacement Surgery

Prior to the procedure, a consultation with an anesthesiologist will be conducted to discuss anesthesia options. This discussion should have been initiated during preoperative hospital visits with the surgeon. Anesthesia alternatives encompass:

  • General anesthesia inducing unconsciousness.

  • Spinal anesthesia rendering the lower body numb while the patient remains awake.

  • Peripheral nerve block a form of regional anesthesia involving the injection of numbing agents near specific nerves to obstruct pain signals from targeted areas. These blocks may be employed in conjunction with general or spinal anesthesia.

Preoperative Preparation:

The surgeon will conduct a pre-surgery assessment, signing the knee with a marker to confirm the correct surgical site.

Surgical Procedure:

A typical partial knee replacement procedure spans 1 to 2 hours.

  • Joint inspection: An incision is made at the front of the knee, allowing the surgeon to explore the three knee compartments, ensuring limited cartilage damage and intact ligaments.

  • Assessment for Total Knee Replacement: If the surgeon deems a partial knee replacement unsuitable, a contingency plan for a total knee replacement may be implemented, with prior discussion to secure patient agreement.

Partial Knee Replacement Procedure:

The procedure involves three fundamental steps:

Bone preparation: Special saws are used to remove damaged compartment cartilage.

Implant placement: Metal covers, replicating joint surfaces, replacing removed cartilage and bone. These metal parts can be cemented to the bone or, in cementless fixation, press-fit to encourage bone integration.

Spacer insertion: A plastic insert is positioned between metal components to create a smooth gliding surface.

Recovery Room at our Hospital

Following the surgery, the patient is transferred to the recovery room for close post-anesthetic monitoring. Depending on the case, the patient is either discharged home or admitted to the hospital room for an overnight stay.

Indications for Knee Replacement:

The recommendation for knee replacement by a Doctors, Surgeons or professionals is contingent upon the persistence of severe symptoms unresponsive to non-surgical interventions. Such symptoms encompass:

  • Joint pain

  • Stiffness

  • Ligament Damage(impaired knee movement)

  • Swelling

Knee replacement surgery is commonly advised for individuals affected by arthritis, with osteoarthritis being the predominant condition leading to this intervention. Although the majority undergoing knee replacement exhibit osteoarthritis, individuals with rheumatoid arthritis may also necessitate this procedure.

In exceptional cases, knee replacement may be suggested by the Doctors in instances of post-traumatic arthritis resulting from a bone fracture in the knee following incidents such as:

  • Car accidents

  • Falls

  • Sports injuries

When to Seek Medical Consultation

Determining the appropriate time to seek medical attention is crucial. In the event of experiencing the following symptoms, prompt contact with our surgeons or healthcare provider is advised:

  • Chest pain.

  • Shortness of breath (dyspnea).

  • Fever exceeding 101 degrees Fahrenheit (39 degrees Celsius).

  • Hemorrhaging.

  • Indications of infection at the surgical site, such as seepage, swelling, discoloration, odor, or a sensation of warmth.

  • Onset or aggravation of pain in the calf, ankle, or foot.

  • Persistent and intense pain unresponsive to prescribed analgesics.
