ACL Tear

Anterior Cruciate Ligament (ACL) Injury & Advanced Reconstruction

A torn anterior cruciate ligament (ACL) is one of the most common yet highly treatable sports injuries. Understanding your injury, stability goals, and surgical or conservative rehabilitation options is the first step toward a safe return to sport and daily performance.

The Anterior Cruciate Ligament (ACL) is one of the four primary ligaments that maintain joint stability in your knee. Running diagonally through the center of the joint, it prevents the shin bone (tibia) from sliding forward relative to the thigh bone (femur) while controlling rotational stability.

Whether from a sudden pivot on the pitch, a jump, or a quick stop, an ACL tear happens in a fraction of a second. Understanding how your ligament was damaged is the first step toward getting your knee stable again.

Arthroscopic view

2. Intra-operative Arthroscopic View

Through high-definition keyhole surgery, I directly inspect your joint to evaluate the exact extent of your tear and ensure every surrounding structure is meticulously treated.

MRI scan

3. Typical MRI Findings

Your MRI gives us a complete picture of your knee. Together, we analyze it to confirm your diagnosis and check if your meniscus or cartilage needs targeted repair at the same time.

Reconstruction

4. ACL Reconstruction (Surgical Technique)

Using precise arthroscopic techniques and your own tissue graft, I reconstruct your ligament to restore its natural anatomy, rotational strength, and long-term joint protection.

Rehabilitation

5. Recovery & Rehabilitation

Surgery is only half the journey. I guide you through a structured, step-by-step rehabilitation plan designed to rebuild your confidence and get you safely back to the activities you love.

“ Clinical Note from Dr. Yousef Muhammad

Not every ACL injury requires immediate surgical reconstruction. The optimal treatment path depends on joint stability, activity expectations, associated meniscus injuries, and your long-term goals. Every treatment plan is individually tailored to restore joint health and safely guide you back to full physical performance.

Frequently Asked Questions

Can an ACL tear heal or be treated without surgery?

Not all ACL tears require surgery. Partial tears or injuries in non-athletic patients with stable knees can often be managed with structured physical therapy and muscle strengthening. However, for active individuals or those experiencing knee instability (“giving way”), surgical reconstruction is usually recommended to restore stability and protect the cartilage and meniscus.

When can I return to daily activities, driving, and full knee flexion after surgery?

Driving is usually permitted after 2 to 4 weeks, depending on which leg was operated on and your pain control. Deep knee bending (such as sitting on the floor or praying with full flexion) is gradually reintroduced during physical therapy as graft healing and range of motion progress safely.

When can I return to sports and running after ACL surgery?

Straight-line running typically begins around 3 to 4 months post-surgery, provided muscle strength and stability are restored. A full return to pivoting and contact sports usually takes between 6 to 9 months, following a personalized rehabilitation program and functional clearance testing.

What is the best graft choice for ACL reconstruction?

The optimal graft depends on your age, activity level, and sport. Common choices include autografts taken from the hamstring tendon, quadriceps tendon, or patellar tendon. During your consultation, Dr. Yousef will evaluate your anatomical needs and athletic goals to select the most suitable graft option for long-term knee stability.
