Quadriceps Sparing Knee Replacement


Healthy Joints • Melbourne

Less pain. Quicker recovery. Subvastus (Quadriceps-Sparing) knee replacement

By gently lifting—rather than cutting—the quadriceps tendon, the subvastus approach aims to reduce muscle trauma. Paired with ERAS best-practice care, patients typically experience less early pain and a faster return to walking and daily activities.

Available at Adeney Private, St Vincent’s Private East Melbourne, and St Vincent’s Private Werribee.

What is the Subvastus (Quadriceps-Sparing) approach?

The incision is on the front/inner side of the knee. The vastus medialis is gently lifted—not cut—to preserve the quadriceps mechanism that straightens the knee.

  • Often less early pain (day-1 and early weeks)
  • Earlier straight-leg raise and easier stairs
  • Pairs naturally with ERAS: pre-hab, modern anaesthesia, early walking

If your knee is very stiff or anatomically complex, another approach may be safer—we’ll discuss the best option for you.

Quadriceps preserved vs split Schematic comparison: subvastus preserves quadriceps; medial parapatellar may split tendon. Subvastus (quad-sparing) Quadriceps preserved Muscle gently lifted Medial parapatellar Quadriceps split/cut
Quadriceps-sparing aims to reduce muscle trauma → often less early pain.

ERAS: Comfort-first, movement-earlyEvidence-based

  • Pre-hab & goal-setting so you know what to expect
  • Modern anaesthesia + multimodal analgesia to reduce opioid need
  • Ice, elevation and swelling-control protocols
  • Guided early mobilisation the day of surgery where safe
  • Telehealth and physio follow-up with clear contacts

Your recovery goals

  • Pain under control with a simple plan
  • Confident transfers and first steps
  • Safe stairs practice and home set-up
  • Daily exercises that fit your life

Quadriceps-sparing (Subvastus) vs Medial Parapatellar: what patients feel

What matters to youSubvastus (quadriceps-sparing)Medial parapatellar (traditional)
Early painMany studies report lower early pain scores (day-1 and early weeks) and easier straight-leg raise for many patients.Effective exposure, though some patients report more early anterior knee pain due to quadriceps/patellar handling.
Early functionBetter early ROM and quicker SLR/stairs reported in several RCTs/meta-analyses.Reliable and familiar; early function can be good but may lag when the quadriceps is incised/everting the patella.
Alignment & safetyModern series show no increase in malalignment or component malposition vs MPP when performed by experienced teams.Gold-standard exposure with excellent visibility; widely used and familiar to many surgeons.
Trade-offsMore technically demanding; operative time similar or slightly longer in some hands.Great exposure in stiff/complex knees; may involve more quadriceps/patellar soft-tissue handling.

Bottom line: we choose the approach that best fits your knee and goals—comfort, confidence, and safe, steady progress.

No-Gap Options

No-Gap knee replacement (selected funds & criteria)

For eligible patients insured with Medibank or Bupa, a No-Gap pathway may be available for primary knee replacement when clinical and fund criteria are met.
