What to Expect : 3 Months post ACL Surgery
WHAT TO EXPECT : 3 MONTHS POST ACL SURGERY
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.
