Pediatric ACL Injury Treatment Options

Non-operative treatment may be considered in carefully selected patients, particularly those with low-demand activity levels, isolated ACL injuries, or very young children in whom surgical risks are especially significant due to substantial remaining growth.

An 8-year follow-up study of non-surgically managed pediatric ACL patients demonstrated that while satisfactory clinical results were achievable with rehabilitation alone, half of patients ultimately required surgical intervention, the majority exhibited altered muscle strength and limb asymmetry, and most modified their sports to avoid pivoting activities. The risk of secondary meniscal tears is substantially higher in non-operatively managed patients — a risk that compounds with time and continued activity.

If non-operative treatment is pursued, it requires:

• Early MRI to identify and document associated injuries
• Age-specific physiotherapy with a focus on neuromuscular retraining and quadriceps/hamstring strengthening
• Use of a functional knee brace for sporting activity
• Frequent monitoring throughout skeletal maturity to detect any secondary joint damage
• Clear criteria for conversion to surgical management if instability persists or secondary injuries develop

Current evidence strongly supports surgical reconstruction for most active pediatric patients with complete ACL tears, including pre-pubertal athletes. Studies show that ACL-injured patients treated non-operatively have lower return-to-sport rates and are more likely to sustain meniscal injuries. These findings hold true for delayed surgery as well — meaning even watchful waiting carries progressive risk. Most pediatric orthopedic specialists recommend surgical reconstruction once the diagnosis is confirmed and pivot-shift instability is demonstrated on examination under anesthesia.

Surgical indications are particularly strong when:

• The patient has a complete ACL tear with confirmed pivot-shift instability
• A concurrent meniscal or cartilage injury is present or at high risk of occurring
• The patient is an active athlete who wishes to return to pivoting sports
• Non-operative management has failed or the patient demonstrates persistent instability

The choice of surgical technique is directly determined by the patient’s skeletal maturity — specifically, how much growth remains. Dr. Patel uses Tanner staging, radiographic bone age (Greulich and Pyle atlas), and full-length lower limb radiographs to precisely characterize each patient’s skeletal status before selecting a surgical approach. This information forms the cornerstone of the pre-operative plan and determines which of the growth-plate–sparing techniques described in the following section is most appropriate.
