Physio Nexus Academy · Clinical Treatment Framework

ACL Reconstruction Rehabilitation

Criterion-based rehabilitation restores extension, quadriceps strength, movement quality, running and sport capacity while respecting surgical and graft-specific precautions.

Assess → classifyTreat → reassessLoad → progress

Clinical decision pathway

A structured plan, not a recipe

Clinician-led · Individualised
01

Understand

Screen safety, identify the likely clinical pattern and agree meaningful goals.

02

Select

Choose only interventions that match the patient's impairments and preferences.

03

Reassess

Repeat the same comparable sign or functional task after key interventions.

04

Progress

Build capacity and participation using measurable response, not session count.

Before choosing an intervention

Clinical reasoning

  1. 1Follow surgeon-specific restrictions first, then use criteria rather than calendar time alone for progression.
  2. 2Early priorities are extension, swelling control, quadriceps activation and normal gait.
  3. 3Later priorities are strength symmetry, landing control, running, cutting and psychological readiness.

A practical starting sequence

First-session workflow

  1. 1Review operative note, graft and restrictions.
  2. 2Check wound, effusion, extension, flexion, quadriceps activation, gait and DVT warning signs.
  3. 3Start extension restoration and quadriceps activation immediately if permitted.

Assessment & examination

  1. 1Confirm graft type, associated meniscal/cartilage procedures, surgeon restrictions and current rehabilitation phase before progressing loading
  2. 2Track effusion, wound status when relevant, knee extension and flexion, pain and gait
  3. 3Assess quadriceps activation and strength; document the method and compare over time
  4. 4Monitor calf symptoms and screen for DVT when clinically indicated
  5. 5Introduce running, hop and change-of-direction testing only when prerequisites are met and the protocol permits
  6. 6Assess confidence, fear of reinjury and patient-specific work/sport demands alongside physical capacity

Red flags & safety screen

  1. 1Possible DVT: new calf swelling/pain, warmth or unexplained shortness of breath; urgent medical assessment is required, with emergency response for chest pain or breathing difficulty
  2. 2Possible infection: fever, increasing wound redness, drainage or rapidly worsening pain/swelling
  3. 3Locked knee, sudden major extension loss or acute instability event
  4. 4New neurovascular symptoms or rapid unexpected deterioration

Indication · dosage · response

Manual therapy application

  1. 1Patellar mobilization after surgery when safe and needed for mobility.
  2. 2Gentle tibiofemoral mobilization for ROM when cleared.
  3. 3Scar mobilization only after full wound healing.

Adapt to irritability and capacity

Exercise prescription & dosage

  1. 1Quad sets: 5–10-second holds × 10–20 reps, multiple times/day early.
  2. 2Straight-leg raise when no extension lag: 2–3 sets × 8–15 reps.
  3. 3Sit-to-stand/squat/leg press as allowed: 3 sets × 8–15 reps.
  4. 4Progressive knee extension and hamstring work according to graft/protocol.
  5. 5Later running, plyometrics and change-of-direction are criterion-based.

Modalities & adjuncts

  1. 1Cryotherapy/compression 10–20 minutes for swelling/comfort.
  2. 2NMES can be paired with quadriceps contraction when activation is poor.

Progression & regression rules

  1. 1Do not progress high-impact work with significant effusion or poor strength control.
  2. 2Use objective strength and hop testing before return-to-sport decisions.
  3. 3Aim for high limb symmetry plus good movement quality, not symmetry alone.

Home programme

  1. 1Daily extension work early
  2. 2Adhere to weight-bearing/brace instructions
  3. 3Track swelling response to loading

Outcome measures

  1. 1IKDC/KOOS
  2. 2Effusion
  3. 3ROM
  4. 4Quadriceps limb-symmetry index
  5. 5Hop test battery
  6. 6Psychological readiness

Common clinical mistakes

  1. 1Losing full extension early.
  2. 2Progressing based only on postoperative weeks.
  3. 3Underloading quadriceps.
  4. 4Returning to sport without strength/hop testing.

Patient education & self-management

  1. 1Explain that swelling is a load-response signal.
  2. 2Teach DVT/infection warning signs.
  3. 3Set expectations for long-term strength and sport-specific rehabilitation.

Referral & escalation

  1. 1Contact surgical team for increasing effusion, extension block, instability, infection or DVT concern

Clinical use & safety note

This is an educational clinical framework, not an individual prescription or a substitute for diagnosis, medical assessment, local protocols or professional judgement. Exercise dose, manual techniques and adjuncts must be adapted to examination findings, irritability, comorbidities, precautions, patient goals and response. Obtain informed consent, work within training and scope, and refer when indicated. Do not apply every intervention listed to every patient.

The PNA treatment principle

The best plan is not the one with the most techniques. It is the one that identifies the patient's main problem, selects a defensible intervention, measures the response and steadily restores meaningful function.
