What to Expect : 3 Months post ACL Surgery

WHAT TO EXPECT : 3 MONTHS POST

Note : this are the expectations post a specific surgical technique (All inside technique) in an isolated ACL reconstruction case with peroneus graft ( OUR USUAL TECHNIQUE)

1. Healing & Graft Status

  • The graft is revascularizing and integrating into bone tunnels.
  • It’s not fully strong yet, so pivoting, twisting, or high-impact activity should still be avoided.
  • Internal healing continues even if you “feel normal.”
  • Graft is the weakest between 6 weeks – 4 months, avoid engaging sports.
  • You may experience swelling and pain post exertion/ stiffness at night time also.

2. Range of Motion (ROM)

  • Goal:
    • Full extension (0°) — must be achieved.
    • Flexion: 120–135° (depending on individual progress).
  • Mild tightness at end-range flexion may persist.
  • Swelling should be minimal or only mild after exercises.
  • No restrictions in walking/limp
  • Jogging or brisk walk should not be painful
  • Stairs and car driving should be comfortable.

3. Muscle Strength

  • Quadriceps and hamstring strength: around 60–70% of the opposite side.
  • Ongoing focus:
    • Quadriceps activation (especially VMO).
    • Hamstring co-contraction and hip strengthening.
  • Still some visible thigh muscle loss is normal.
  • Continue on return to sports training
  • Proprioceptive and balance training is mandatory

4. Activities & Physiotherapy

Allowed / Common at 3 months:

  • Stationary cycling (no resistance → gradual resistance).
  • Elliptical trainer, treadmill walking (no running).
  • Step-ups, closed-chain squats, lunges (under supervision).
  • Balance & proprioception training (wobble board, single-leg stands).
  • Squats even weighted squats
  • Leg press 
  • Avoid treadmill

Still Avoid:

  • Jumping, twisting, pivoting, cutting movements.
  • Outdoor running (usually begins around 4–5 months if strength allows).
  • Sports or contact drills.

5. Symptoms You Shouldn’t Have

  • Locking, giving way, or instability — may suggest incomplete strength or graft laxity.
  • Persistent swelling or warmth — may indicate synovitis or overuse.
  • Sharp pain with movement — could be cyclops lesion or over-aggressive rehab.

6. Expected Functional Level (END POINTS)

    • Normal walking without limp.
    • Climbing stairs comfortably.
    • Light daily activities and desk work with ease.
    • Driving (for right knee) usually allowed if reflexes and control are adequate.

7. Red Flags to Re-check With Surgeon

  • Recurrent swelling after exercise (moderate)
  • Loss of previously gained flexion or extension.
  • Knee “giving way” episodes.
  • Persistent anterior knee pain (possible patellar tendinitis or graft impingement).
  • Incomplete knee extension

NOTE : THESE ARE SOME REFERENCE END POINTS FOR ISOLATED ACL TEARS, THERE MAY BE SOME VARIATION. DISCUSS WITH YOUR SPORTS SURGEON IN DETAIL.

NOTE : MENISCUS TEARS IN ADDITION DELAY THE RECOVERY TIMELINES BY AROUND 4-6 WEEKS.
