Prehab & Rehabilitation — all lessons

The preoperative phase (prehabilitation)

Exercise before surgery — prehabilitation to improve fitness, strength and outcomes, with examples for ACL reconstruction and major surgery.

Advanced Evidence: Emerging evidence 3 min read Reviewed 2026-10-31 Status: draft

Learning objectives

  • Explain the rationale for prehabilitation
  • Summarise evidence for total-body and joint-specific prehab
  • Design a prehab programme with surgical team input
  • Set expectations and safety boundaries

Before this lesson

Why this matters

People who enter surgery fitter and stronger often recover function sooner. Prehab is a practical opportunity, especially for planned surgery.

Evidence

A meta-analysis of total-body prehabilitation found improvements in some postoperative outcomes, though evidence quality varied [santamina2014].

Joint-specific examples

SurgeryPrehab priorities
ACL reconstructionFull knee extension, minimal swelling, quadriceps activation and strength, normal gait
Knee/hip replacementStrength, range, walking capacity, aerobic fitness
Major abdominal surgeryAerobic fitness, breathing exercises, strength

Loading principles still apply [khan2009], within surgical restrictions.

Common mistakes and misconceptions

Case study

A 28-year-old awaiting ACL reconstruction completes 6 weeks of prehab, restoring full extension and improving quadriceps strength. Early post-operative milestones are reached sooner than his surgeon’s usual expectations.

Short-answer & application questions

  2. List criteria a surgeon may want before ACL reconstruction.
  3. Explain prehab benefits to a patient.

Key takeaways

  • Prehabilitation aims to enter surgery fitter, stronger and with better function.
  • Total-body prehab has been associated with improved postoperative outcomes in some populations.
  • For ACL reconstruction, restoring range, reducing swelling and building quadriceps strength before surgery is commonly recommended.
  • Programmes must follow surgeon and physiotherapist guidance.
