Partial Knee Replacement Surgery

Targeted Surgical Care for Partial Knee Joint Damage

Are you suffering from knee pain while walking, moving up stairs, or standing for long durations? The pain, swelling, and stiffness are often due to wear of the protective cartilage of the knee.

Your doctor may recommend knee replacement surgery to you after other non-surgical methods fail to provide relief. But not all such issues necessitate complete knee joint replacement. If damage is not widespread and limited only to one component of the knee joint, then healthy joint components are preserved with the partial knee replacement surgery.

This effective treatment option is often recommended for early-stage knee joint degeneration in which damage is of moderate levels and is localised. The outcomes of this treatment are more favourable if the overall knee stability and alignment are still preserved.

What Is Partial Knee Replacement?

Partial knee replacement (PKR) is also called unicompartmental knee replacement because in this surgical procedure only the damaged portion of the knee joint is replaced with an artificial implant.

The following tissues are preserved in this joint replacement procedure:

  • Healthy cartilage
  • Unaffected bone surfaces
  • Major ligaments of the knee

We understand the fact that everybody is different; so are everyone’s knee joints and the associated issues. Our specialists select the patient-specific implant designs that support natural joint movements without pain and swelling by providing intact joint surfaces.

When Is Partial Knee Replacement Surgery Indicated?

Early-stage knee damage can be stopped from progressing and can be effectively reversed with non-surgical conservative treatment options such as medications, supplementation, physiotherapy, weight management, and injections. If these treatments fail or are no longer effective for relieving pain, knee replacement may be recommended. Your orthopaedic surgeon may consider partial knee replacement if:

  • Damage is localised
  • Pain is limited to one side of the knee
  • Ligaments are intact
  • Knee alignment isn’t disturbed
  • No widespread inflammation

Your doctor will recommend PKR on the basis of thorough symptom analysis, cause of knee damage, clinical examination, imaging test reports, and patient activity requirements.

Knee Conditions Treated with Partial Knee Replacement

The following are the conditions that may lead to knee joint damage and necessitate partial knee replacement:

  • Early-stage or moderate osteoarthritis affecting one compartment
  • Medial or lateral compartment degeneration
  • Isolated cartilage loss with preserved ligaments
  • Knee pain localised to one area
  • Functional limitation despite conservative treatment

How Is Partial Knee Replacement Different From Total Knee Replacement?

Knowing the difference between these two treatments can help patients make informed decisions:

Partial Knee Replacement

  • Replaces only one affected compartment
  • Preserves healthy bone and ligaments
  • Suitable for early, localized disease
  • Smaller incision and less tissue trauma
  • Faster recovery and more natural motion
  • Not suitable for widespread arthritis

Total Knee Replacement

  • Replaces all damaged joint surfaces
  • Removes most joint surfaces
  • Suitable for advanced, multi-compartment disease
  • Larger incision and more extensive surgery
  • Longer recovery period
  • Suitable for widespread degeneration
In simple words, the extent of damage and activity needs of the patients are the main deciding factors behind the treatment choice.

Implants Used in Partial Knee Replacement

The following are the types of specialised implants designed to fit only the affected part of the knee joint:

Femoral Component
  • Covers the damaged portion of the thigh bone
  • Made from cobalt-chromium or similar alloys
  • Allows smooth joint movement
Tibial Component
  • Metal base fixed to the affected area of the shinbone
  • Supports body weight in the treated compartment
Polyethylene Insert
  • High-quality medical plastic spacer
  • Acts as a cushion and reduces friction

The objective is to preserve natural knee joint tissue as much as possible. Therefore, only a few components are used.

Factors Affecting Implant Selection in Partial Knee Replacement

Implant selection mainly depends on the following factors:

  • Age
  • Bone quality
  • Bone and joint anatomy
  • Activity levels
  • Type of disorder
  • Extent and location of cartilage damage
  • Knee alignment and ligament stability
  • Surgeon’s intraoperative assessment

Surgical Approaches for Partial Knee Replacement

The following are the techniques used for partial knee replacement, depending on patient needs and type of damage:

  • Minimally invasive approaches: IIt is the commonly used surgical approach. It is done using smaller incisions and tiny surgical instruments. A small camera is also inserted in the surgical site to have better vision. It supports better implant positioning due to better surgical site vision.
  • Conventional total knee replacement: It is done using one long incision. It causes more tissue damage. It is rarely opted for partial knee replacement. But it may be opted if the anatomy of the joint is complex.

The choice of technique is determined by the type of joint deformity, bone structure, and surgical planning.

Right Candidate for Partial Knee Replacement

You may be considered a good candidate if you have:

  • Knee pain limited to one compartment
  • Preserved knee stability and ligaments
  • Mild to moderate stiffness
  • Minimal knee deformity
  • Good response potential to rehabilitation

Patient age, activity expectations, and joint condition are carefully evaluated.

During Surgery

What to Expect During and After Surgery

The surgery is usually completed between one and two hours. The damaged bone and cartilage are taken out during the procedure, and bone cement or press-fit techniques are used to fix the implants. Before closing, the alignment and stability of the joint are checked.

The patient may expect the following outcomes after the surgery:

  • Assisted standing and walking usually begin within 24–48 hours
  • Physiotherapy starts early to restore movement and strength
  • Swelling and discomfort reduce gradually with rehabilitation

Recovery and Long-Term Outcomes

Recovery progresses in phases:

  • First few weeks

    Improved mobility with minimal support

  • 3–4 weeks

    Better walking endurance and reduced pain

  • 2–3 months

    Return to most daily activities

Our modern knee implants are selected and positioned in such a way as to last for 10–15 years or longer, especially with appropriate activity modification and follow-up care.
