An ACL injury is one of the most common and serious orthopedic conditions that affect the knee joint, particularly among athletes and physically active individuals. The anterior cruciate ligament (ACL) is essential for knee stability, and its damage can severely impact mobility and performance. In this blog, we’ll explore everything you need to know about an ACL injury—its causes, symptoms, treatments, and recovery process. We’ll also introduce you to Dr. Divyanshu Dutt Dwivedi, a leading orthopedic doctor in Lucknow, specializing in ACL reconstruction and sports medicine.

What is an ACL Injury?

The anterior cruciate ligament (ACL) is a critical ligament inside the knee joint. Its primary function is to prevent the forward movement (anterior translation) of the tibia (shinbone) over the femur (thighbone), while also stabilizing the knee during rotation. An ACL injury typically occurs when the ligament is stretched or torn due to a sudden twist or impact.

Such injuries are common during sports that involve jumping, pivoting, or sudden changes in direction, such as football, basketball, and skiing. A torn ACL causes the knee to feel unstable, especially when walking on uneven surfaces or descending stairs.

Common Causes and Risk Factors of ACL Injury

Causes

Sudden stops or changes in direction while running
Improper landing after a jump
Direct impact to the knee
Twisting the knee while the foot is planted

Risk Factors

Participation in high-risk sports
Weak hamstrings or quadriceps
Poor coordination and muscle control
Improper footwear or athletic surfaces

An ACL injury can occur in anyone but is particularly common among athletes and active individuals. Female athletes are also at a higher risk due to anatomical and hormonal differences.

Symptoms of ACL Injury

Identifying the signs of an ACL injury early can help ensure timely treatment and prevent further joint damage. Common symptoms include:

A popping sound at the time of injury
Immediate swelling in the knee
Pain and restricted movement
Knee instability or the sensation of the knee “giving way”
Difficulty bearing weight

If these symptoms occur, it’s crucial to consult a specialist like Dr. Divyanshu Dutt Dwivedi, an experienced orthopedic doctor in Lucknow who specializes in knee injuries and arthroscopic surgery.

Why ACL Injuries Must Be Taken Seriously

Each episode of instability following an ACL injury can damage the menisci, the cartilage cushions within the knee joint. A torn meniscus compromises weight distribution, leading to increased friction between bones and early osteoarthritis.

Ignoring an ACL injury not only reduces quality of life but can also cause permanent joint degeneration. Hence, early diagnosis and proper treatment are essential.

ACL Injury Treatment Options

Non-Surgical Management

In cases of partial tears or for patients with a sedentary lifestyle, non-surgical treatment may be considered. This includes:

RICE (Rest, Ice, Compression, Elevation)
Knee bracing
Physical therapy and strengthening exercises

However, for active individuals or complete ACL tears, surgery is usually the preferred option.

ACL Reconstruction Surgery

ACL reconstruction surgery is the most effective way to restore knee stability in a complete ACL tear. This minimally invasive procedure is performed using arthroscopy (keyhole surgery). Dr. Divyanshu Dutt Dwivedi, one of the best orthopedic surgeons in Lucknow, regularly performs ACL reconstruction with excellent patient outcomes.

Procedure

A tendon (usually from the hamstring or patellar tendon) is harvested.
Tunnels are drilled into the tibia and femur.
The tendon graft is inserted to replace the damaged ACL.
Over time, the graft undergoes ligamentization, where it transforms into a functional ligament.

This modern technique ensures minimal scarring, faster recovery, and long-term joint stability.

ACL Injury Recovery Timeline

Recovery from an ACL injury—especially post-surgery—requires a structured rehabilitation plan. Below is a general recovery timeline:

Week 1

Patient is mobilized the same day
Use of walker for initial support
Pain and swelling managed through medication

Weeks 2–6

Partial weight bearing for 2 weeks
Aim for 90° knee movement by week 2
Full range of motion by week 4–6
Physiotherapy sessions begin

Weeks 6–12

Full weight bearing without support
Strength and balance training
Focus on quadriceps and hamstring recovery

6–9 Months

Return to running and sports
Only after detailed evaluation of muscle strength, knee stability, and psychological readiness
A final clearance by the surgeon, such as Dr. Divyanshu, ensures safe return to play

Preventing ACL Injuries

Preventing an ACL injury is better than treating one. Here are preventive tips:

Warm-up and stretch before physical activity
Strengthen muscles around the knee
Use proper technique for jumping and landing
Improve balance and coordination through neuromuscular training
Wear sport-specific footwear

Athletes can benefit from specialized ACL injury prevention programs under the guidance of experts like Dr. Divyanshu Dutt Dwivedi, who also consults on sports fitness and knee injury prevention.
