ACL Reconstruction in Montclair, NJ

The anterior cruciate ligament (ACL) is a key stabilizer of the knee. A torn ACL often happens during cutting, pivoting, or landing and frequently doesn't heal on its own. Reconstruction replaces the torn ligament with a graft to restore stability and help you return to sport and daily activity.

Symptoms

  • A 'pop' at the time of injury
  • Rapid swelling within hours
  • A feeling that the knee 'gives way' or buckles
  • Difficulty with cutting, pivoting, or stairs

Causes & who it affects

Most ACL tears are non-contact injuries — sudden deceleration, a pivot, or an awkward landing. They're common in soccer, basketball, football, and skiing, and can occur alongside meniscus or cartilage injuries.

Diagnosis

Evaluation begins with your history and a hands-on exam (including Lachman and pivot-shift tests). Imaging — typically X-rays and an MRI — confirms the tear and identifies any associated meniscus or cartilage damage.

Treatment options

1

Pre-operative rehab ('prehab')

Reducing swelling and restoring motion and quad strength before surgery improves outcomes.

2

Arthroscopic reconstruction

Minimally invasive surgery replaces the ACL with a graft (often patellar tendon, hamstring, or quad tendon), chosen with you based on sport and goals.

3

Treating associated injuries

Meniscus repair or cartilage work performed at the same time when needed.

4

Structured rehabilitation

A progressive physical-therapy program is central to recovery and return to play.

Recovery & return to play

Weeks 0–2Control swelling, regain full extension, begin gentle motion and quad activation.
Weeks 2–12Progressive strengthening, normalize gait, build single-leg control.
Months 3–6Running, agility, and sport-specific drills as strength benchmarks are met.
Months 9+Return to cutting/pivoting sport after passing functional and strength testing.

Timelines are general and individualized to each patient — your plan may differ.

Frequently asked questions

Return to cutting and pivoting sports is typically around 9–12 months, and is based on meeting strength and functional milestones — not the calendar alone. Your timeline is individualized.
