    - Compression: Bandaging the knee with an elastic bandage to reduce swelling.
    - Lift the limb: Lifting the leg on pillows while lying down to reduce swelling.
    - Pain and anti-inflammatory medications: Using non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.

   3.2 Intermediate phase (2-6 weeks)

    3.2.1 Intermediate phase goals

    - Continue to reduce pain and swelling
    - Restore range of motion
    - Strengthening the muscles around the knee

    3.2.2 Therapeutic interventions

    - Range of Motion Exercises: Gentle stretching and mobilization exercises to restore full range of motion to the knee joint.
    - Strengthening exercises: Exercises to strengthen the quadriceps muscles of the thigh, gluteal muscles and hamstrings, such as squats with light loads, leg extensions on a machine or isometric exercises.
    - Manual therapy: Massage, soft tissue techniques and joint mobilizations to reduce muscle tension and improve circulation.
    - Kinesitherapy: Exercises in water, such as walking in a pool, can reduce stress on the knee joint and facilitate rehabilitation.

   3.3 Late phase (6-12 weeks)

    3.3.1 Late phase goals

    - Achieve full range of motion
    - Strengthen muscles and improve stability
    - Preparing to return to running

    3.3.2 Therapeutic interventions

    - Advanced Strengthening Exercises: Introduce more intense strength exercises such as squats with heavier weights, weightlifting, leg extensions on a machine.
    - Proprioception and coordination exercises: Exercises to improve balance and coordination, such as standing on one leg, walking on unstable surfaces or using a rehabilitation ball.
    - Functional exercises: Exercises that mimic running movements, such as running on a treadmill with a gentle incline, sprints and running techniques.

   3.4 Return to running phase (12 weeks or more)

    3.4.1 Goals of the return to running phase

    - Gradual return to running
    - Prevention of injury recurrence
    - Maintenance of healthy training habits

    3.4.2 Therapeutic interventions
