4. Pain Management

For patients experiencing pain associated with dislocations, nonsteroidal anti-inflammatory drugs (NSAIDs) may be recommended to reduce inflammation and pain.

Surgical Treatment Options

If conservative treatments fail to provide relief or if dislocations are frequent and severe, surgical intervention may be necessary. Common surgical options include:

1. Arthroscopic Surgery

Arthroscopy is a minimally invasive procedure that allows surgeons to visualize and repair the structures within the knee joint. This may involve:
- Repairing Ligaments: If ligaments are torn or lax, they may be repaired or reconstructed to restore stability.
- Removing Loose Bodies: Any loose fragments within the joint that could contribute to dislocation may be removed.

2. Open Surgery

In more complex cases, open surgical techniques may be required. This could involve:
- Reconstruction of the Ligaments: Procedures such as the reconstruction of the anterior cruciate ligament (ACL) or medial collateral ligament (MCL) may be performed.
- Realignment Procedures: In cases where the alignment of the knee is contributing to dislocations, realignment of the bones may be necessary.

3. Genicular Nerve Blocks

For chronic pain management associated with recurrent dislocations, genicular nerve blocks may be considered. This procedure involves injecting anesthetic near the nerves that supply the knee, providing pain relief and potentially improving function[7].

Post-Treatment Rehabilitation

Regardless of the treatment approach, rehabilitation is crucial for recovery. A structured rehabilitation program typically includes:
- Gradual Return to Activity: Patients are guided on how to safely return to their normal activities and sports.
- Continued Strengthening and Flexibility Exercises: Ongoing physical therapy may be necessary to maintain strength and prevent future dislocations.
