• Range of Motion Exercises: Gentle stretching and mobility exercises help maintain joint flexibility and prevent stiffness.
• Manual Therapy: Techniques such as joint mobilization may be employed to improve knee function.

Pain Management

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Medications like ibuprofen or naproxen can help reduce pain and inflammation.
• Ice Therapy: Applying ice packs to the knee can alleviate swelling and discomfort.

2. Orthotic Devices

Knee Braces

• Functional Bracing: A knee brace may provide additional support and stability, particularly during activities that stress the knee.
• Unloader Braces: These are designed to shift weight away from the affected area, potentially reducing pain during movement.

3. Invasive Treatments

Injections

• Corticosteroid Injections: These can provide temporary relief from inflammation and pain.
• Hyaluronic Acid Injections: This treatment aims to improve lubrication in the joint, potentially enhancing mobility and reducing pain.

Surgical Options

• Arthroscopy: In cases where conservative management fails, arthroscopic surgery may be indicated. This minimally invasive procedure allows for direct visualization and treatment of the meniscal tear.
• Meniscectomy: Removal of the damaged meniscal tissue.
• Meniscal Repair: If the tear is suitable for repair, this option aims to preserve as much of the meniscus as possible.

4. Post-Treatment Rehabilitation

Following any surgical intervention, a structured rehabilitation program is critical. This typically includes:
- Gradual Return to Activity: A phased approach to resuming normal activities, guided by a physical therapist.
