I'm an expert in the field of sports medicine with a focus on injury recovery and prevention. It's important to understand that healing times can vary significantly based on the severity of the injury, the individual's overall health, and the specific treatment plan followed. Let's delve into the specifics of healing a sprained knee ligament.

Step 1: Initial Assessment and Diagnosis
The first step in treating a sprained knee ligament is to determine the severity of the injury. Ligament sprains are typically classified into three grades:

- Grade I: Mild sprain with minimal damage to the ligament.
- Grade II: Moderate sprain with partial tearing of the ligament.
- Grade III: Severe sprain indicating a complete tear of the ligament.

Step 2: Immediate Treatment
Regardless of the grade, immediate treatment often involves the RICE protocol:
- Rest: Avoid putting weight on the injured knee.
- Ice: Apply ice to reduce swelling and inflammation.
- Compression: Use a compression bandage to help control swelling.
- Elevation: Keep the knee elevated to reduce swelling.

Step 3: Healing Time
The healing time for a sprained knee ligament can vary:

- Grade I sprains are mild and usually heal within a few weeks. Athletes can often return to their activities within a week or two with proper care.
- Grade II sprains take longer to heal and might require up to six weeks for full recovery. During this time, physical therapy may be necessary to regain strength and flexibility.
- Grade III sprains are the most severe and can take several months to heal. Surgery may be required, followed by a lengthy period of rehabilitation.

Step 4: Rehabilitation
Rehabilitation is a crucial part of the recovery process. It involves:
- Strengthening exercises to improve the stability of the knee joint.
- Flexibility exercises to regain the range of motion.
- Balance training to prevent future injuries.

Step 5: Return to Activity
The decision to return to activity should be based on pain-free movement, full range of motion, and adequate strength. It's essential to progress gradually and not to rush the process to avoid re-injury.

Step 6: Prevention
Prevention of future sprains involves:
- Wearing appropriate footwear.
- Warming up and cooling down properly.
- Strengthening the muscles around the knee.
- Practicing proper technique in sports.

It's important to note that maximal ligament strength occurs after six weeks when the collagen fibers have matured, as mentioned in the reference material. However, this is a general guideline and individual healing times may vary.
