The anterior cruciate ligament (ACL) is one of the most vital ligaments in the knee joint, providing stability during movement. ACL injuries are common, particularly among athletes, but they can affect anyone. The severity of an ACL injury is classified into three grades: Grade I, Grade II, and Grade III. Each grade represents a different level of damage and requires tailored treatment. For customized orthopedic treatments, you can consult one of the best board-certified orthopedic doctors and surgeons, Dr. Siddharth Aggarwal. Now, let us understand these classifications for effective recovery and long-term knee health.
Are Treatments the Same for All Grades of ACL Injuries?
The treatment for ACL injuries is not the same for all grades, as the severity of the damage dictates the approach.
- Grade I: Focuses on conservative management with rest, physical therapy, and minimal medical intervention.
- Grade II: Requires more intensive rehabilitation and, in some cases, surgical intervention.
- Grade III: Necessitates surgical reconstruction followed by a rigorous rehabilitation program.
The overarching goal in all grades is to restore knee stability, strength, and function.
Grade I ACL Injury
A Grade I ACL injury is the mildest form of ACL damage. In this type, the ligament is stretched but not torn. Although the fibers of the ACL may have microscopic tears, the ligament remains functional and continues to provide stability to the knee joint.
Individuals with a Grade I ACL injury often experience mild discomfort, swelling, and a feeling of instability, but they can usually perform most daily activities. However, certain high-impact movements or sudden changes in direction may exacerbate symptoms.
Treatment for Grade I ACL Injuries
Some of the treatments required for Grade I ACL injury includes:
-
Rest and Activity Modification
The primary treatment for a Grade I ACL injury is rest. Patients are advised to avoid activities that stress the knee, such as running, jumping, or twisting movements, to prevent further damage.
-
Ice and Compression
Applying ice packs to the injured area helps reduce swelling and inflammation. Compression bandages or knee braces can provide support and prevent the injury from worsening.
-
Physical Therapy
Physical therapy is essential for Grade I injuries. Strengthening exercises targeting the quadriceps, hamstrings, and calf muscles help restore stability to the knee. Balance training and stretching are also integral components of rehabilitation.
-
Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
Medications like ibuprofen or naproxen may be prescribed to alleviate pain and inflammation.
With proper care, most Grade I ACL injuries heal within 2-4 weeks, and individuals can return to their normal activities.
Grade II ACL Injuries
A Grade II ACL injury is a partial tear of the ligament. This means that the ACL is damaged significantly but not completely severed. Such injuries are less common than Grade I and III injuries and are characterized by moderate instability in the knee joint.
Symptoms of a Grade II ACL injury include more pronounced swelling, pain during movement, and difficulty bearing weight on the affected leg. Patients may also experience the knee “giving way” during activity.
Treatment for Grade II ACL Injuries
These are some of the highly recommended Grade II treatments by the best orthopedic surgeons, including Dr. Sidhharth Aggarwal:
-
Rest, Ice, and Elevation
As with Grade I injuries, resting the knee and applying ice packs are the first steps. Elevating the leg can further reduce swelling.
-
Bracing and Support
Knee braces are often prescribed to immobilize the joint and prevent further damage. A hinged brace may be used to allow limited and controlled movement while protecting the ACL.
-
Physical Therapy
Rehabilitation for Grade II injuries involves a more intensive physical therapy regimen compared to Grade I injuries. Therapy focuses on restoring strength, stability, and range of motion. Some exercises may include leg presses, hamstring curls, and stability exercises using a balance board.
-
Injection Therapies
For some patients, injections such as platelet-rich plasma (PRP) may accelerate healing by stimulating tissue repair in the partially torn ligament.
-
Surgery (Optional)
Surgical intervention is not always necessary for Grade II injuries, but it may be recommended for active individuals or athletes whose knee stability is crucial for their lifestyle.
Recovery from Grade II ACL injuries can take 6-12 weeks or more, depending on the individual’s adherence to the rehabilitation program.

Grade III ACL Injury
A Grade III ACL injury is the most severe type, involving a complete tear of the ligament. This level of damage results in significant knee instability, making it difficult to walk, let alone engage in physical activity.
Symptoms of a Grade III ACL injury include:
- Severe pain immediately after the injury
- Significant swelling within hours
- A popping sound or sensation at the time of injury
- Inability to bear weight on the affected leg
- Frequent episodes of the knee buckling or giving way
Treatment for Grade III ACL Injuries
Following are some of the Grade III ACL injury treatments:
-
Initial Management
The immediate focus is on controlling pain and swelling. Patients are advised to rest, ice the knee, and use crutches to avoid putting weight on the injured leg.
-
Surgical Reconstruction
Surgery is the primary treatment for Grade III ACL injuries, particularly for active individuals. The procedure involves reconstructing the torn ligament using a graft from another tendon in the patient’s body (such as the hamstring or patellar tendon) or a donor.
Minimally invasive techniques, such as arthroscopic surgery, are commonly used to reduce recovery time and complications. You can consult Dr. Sidhharth Aggarwal to know more about the treatments for grade III injuries.
-
Post-Surgical Rehabilitation
Rehabilitation after surgery is a multi-phase process that can take 6-12 months. The program includes:
Phase 1: Pain and swelling control, gentle range-of-motion exercises
Phase 2: Strengthening exercises for surrounding muscles
Phase 3: Balance training and functional activities
Phase 4: Gradual return to sports-specific movements and activities
-
Long-Term Management
Some patients may require ongoing physiotherapy or periodic check-ups to ensure full recovery and prevent re-injury.
Conclusion
ACL injuries, whether mild or severe, require prompt attention and tailored treatment. While Grade I and II injuries often heal with conservative approaches, Grade III injuries typically demand surgical intervention for complete recovery. Proper diagnosis and treatment are essential to prevent long-term complications, such as chronic instability or arthritis.
