For many patients, especially those with partial ruptures or minimal symptoms, conservative management may be sufficient. This includes:

• Rest: Avoiding activities that exacerbate the condition is crucial for healing.
• Ice Therapy: Applying ice packs can help reduce swelling and alleviate pain.
• Compression and Elevation: Using compression bandages and elevating the leg can further assist in managing swelling.
• Physical Therapy: Once the acute phase has passed, physical therapy may be recommended to restore strength and flexibility. This often includes specific exercises tailored to the individual’s needs.

2. Medications

• Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can help manage pain and inflammation.
• Corticosteroid Injections: In some cases, corticosteroid injections may be considered to reduce inflammation, although they should be used cautiously due to potential side effects on tendon healing.

3. Surgical Intervention

If conservative treatments fail to provide relief or if the rupture is complete, surgical intervention may be necessary. Surgical options include:

• Tendon Repair: This involves suturing the torn ends of the tendon back together. The specific technique may vary based on the location and severity of the rupture.
• Tendon Transfer: In cases where the tendon is severely damaged, a tendon transfer from another part of the body may be performed to restore function.

4. Postoperative Rehabilitation

Following surgery, a structured rehabilitation program is critical for recovery. This typically includes:

• Immobilization: The affected leg may be placed in a cast or splint to allow the tendon to heal properly.
• Gradual Mobilization: Once healing progresses, physical therapy will focus on gradually increasing range of motion and strength.
