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.
Contemporary theatres with a coordinated peri-operative team focused on comfort, pain control and early mobility.

- Enhanced recovery nursing
- Local rehab options coordinated
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.
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 you | Subvastus (quadriceps-sparing) | Medial parapatellar (traditional) |
|---|---|---|
| Early pain | Many 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 function | Better 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 & safety | Modern 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-offs | More 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 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.
Eligibility varies by policy and clinical factors. We’ll confirm details with your fund and provide a written estimate.
Next steps
- Book a consultation (telehealth available).
- Pre-hab & medical optimisation to set you up for success.
- Subvastus (or the approach that best fits you) + ERAS plan.
- Guided early mobilisation and personalised rehab.

We’re happy to discuss how these findings apply to your situation, including when another approach may be safer (e.g., very stiff or complex knees).
