Partial Knee Replacement

Partial Knee Replacement, also known as Unicompartmental Knee Replacement, Unicondylar Knee Replacement, Half Knee Replacement, or Knee Microplasty, is a type of Knee Replacement Surgery used when damage is limited to a specific part of the knee joint.

Unlike Total Knee Replacement, Partial Knee Replacement focuses on removing and replacing only the severely damaged portion of the knee while preserving the healthier parts of the joint.

At Asian Orthopaedic Hospital, patients seeking Knee Replacement Surgery in Sabarmati receive a Partial Knee Replacement plan tailored to the location and extent of knee damage, the condition of the surrounding structures, and the patient’s individual requirements.

What Is Knee Microplasty?

In Partial Knee Replacement, the damaged or worn portion of the knee is removed and replaced with an artificial implant made from metal and high-grade polymer.

The procedure preserves the majority of the knee joint by treating only the damaged surfaces. This makes it different from Total Knee Replacement, where the damaged surfaces of the entire knee joint are replaced.

Partial Knee Replacement may be considered when osteoarthritis has primarily affected one side or compartment of the knee while the remaining parts of the joint are relatively preserved.

Key Features of Partial Knee Replacement

  • Treats only the damaged portion of the knee
  • Preserves much of the natural knee structure
  • Uses artificial metal and high-grade polymer components
  • May help preserve natural knee movement and stability
  • Can be considered before more extensive joint damage develops

The live service page notes that Partial Knee Replacement can preserve approximately 70–75% of the natural knee bones and ligaments.

When Is Partial Knee Replacement Considered

Partial Knee Replacement may be considered when osteoarthritis has primarily affected one side of the knee, particularly during earlier stages of the condition.

A detailed orthopaedic assessment is important to determine whether the damage is sufficiently localized for a partial replacement.

Preserving the Natural Knee

One of the important features of Partial Knee Replacement is preservation of the ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament) when they are suitable for preservation.

These ligaments contribute to natural knee movement, stability, and balance after surgery

Treating Localized Joint Damage

When only one compartment of the knee is significantly damaged, treating the affected area rather than replacing the entire joint may be considered.

Individual Assessment

The suitability of Partial Knee Replacement depends on the condition of the knee, extent of cartilage damage, ligament condition, and other clinical factors. A specialist evaluation is required before deciding whether Microplasty is appropriate.

Partial Knee Replacement Journey

Partial Knee Replacement involves careful assessment, surgical planning, treatment of the damaged knee compartment, and appropriate recovery support.

Detailed Knee Evaluation

The knee is assessed to identify the location and severity of joint damage and determine whether the condition is suitable for partial replacement.

Personalized Surgical Planning

The surgical approach is planned according to the affected compartment, cartilage condition, ligament status, knee stability, and individual patient requirements.

Partial Knee Replacement Surgery

During surgery, the severely damaged portion of the knee is removed and replaced with appropriate artificial components while preserving the healthier parts of the joint wherever possible.

Recovery & Physiotherapy

Recovery begins after surgery with gradual mobilization and appropriate follow-up. Physiotherapy may be recommended depending on the patient’s condition and recovery needs.

FAQ’s

If your knee damage is limited to just one part of the joint, while the rest of the knee and its ligaments remain healthy.

Only the damaged section of the knee is replaced, while the healthy bone, cartilage, and ligaments are preserved.

Yes, recovery is generally quicker since less bone and tissue are involved in the surgery.

Yes, because more of your original knee is preserved, movement often feels closer to natural.
