Persistent Pain in Left Knee: Causes and Treatment Options - Orthopedics

More Info

---

Persistent pain in the knee, especially following a traumatic event like a car accident, can be quite concerning and may stem from various underlying issues. In your case, the history of a meniscus tear and ongoing pain suggests that there may be residual damage or complications related to the initial injury.


Possible Causes of Persistent Knee Pain
1. Meniscus Injury: Since you were diagnosed with a medial meniscus tear, it’s possible that the tear has not healed properly or that there is a new tear or degeneration of the meniscus. The meniscus acts as a cushion and stabilizer for the knee joint, and any damage can lead to pain, swelling, and limited mobility.

2. Cartilage Damage: Along with the meniscus, the articular cartilage that covers the ends of the bones in the knee joint can also be damaged during an injury. Cartilage damage can lead to osteoarthritis over time, which is characterized by joint pain, stiffness, and swelling.

3. Ligament Injuries: Injuries to the ligaments, such as the anterior cruciate ligament (ACL) or medial collateral ligament (MCL), can also cause persistent pain and instability in the knee. These injuries may not always be apparent immediately after an accident.

4. Synovitis: Inflammation of the synovial membrane, which lines the knee joint, can occur due to injury or overuse. This condition can cause pain and swelling, particularly during movement.

5. Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion the knee joint, can also lead to pain, especially when kneeling or applying pressure to the knee.

6. Referred Pain: Sometimes, pain in the knee can be referred from other areas, such as the hip or lower back, particularly if there are issues with the sciatic nerve or other structures.


Treatment Options
1. Physical Therapy: Engaging in a structured physical therapy program can help strengthen the muscles around the knee, improve flexibility, and restore function. A physical therapist can tailor exercises to your specific needs and limitations.

2. Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation. However, it’s important to use them as directed and be aware of potential side effects, especially with long-term use.

3. Injections: Corticosteroid injections can provide temporary relief from inflammation and pain. Hyaluronic acid injections may also be considered to lubricate the joint.

4. Surgery: If conservative treatments fail and the pain significantly affects your quality of life, surgical options may be explored. This could include arthroscopy to repair or remove damaged meniscal tissue or other procedures to address cartilage damage.

5. Activity Modification: Avoiding activities that exacerbate the pain, such as kneeling or high-impact sports, can help manage symptoms. Low-impact exercises like swimming or cycling may be beneficial.

6. Weight Management: Maintaining a healthy weight can reduce stress on the knee joint, potentially alleviating pain.


Conclusion
Persistent knee pain following an injury is not uncommon, and it’s crucial to seek a thorough evaluation from an orthopedic specialist. They may recommend imaging studies, such as an MRI, to assess the current state of the knee structures. Based on the findings, a personalized treatment plan can be developed to address your specific issues and improve your quality of life. Remember, early intervention can often lead to better outcomes, so don’t hesitate to seek medical advice.
