Deep pain in the popliteal fossa of the knee?

Hello Doctor, I have been experiencing knee pain for almost three years now.
During this time, I have undergone three MRI scans and had an arthroscopic surgery in early 2021 to remove a bucket handle tear of the meniscus.
However, the surgery did not improve my symptoms.
My knee is almost constantly in pain (whether I am lying down or sitting).
The pain is located deep in the popliteal fossa, on the lateral side.
In the morning, right after I wake up, there is about a 10 to 20-minute period when my knee does not hurt, likely due to the accumulation of joint fluid.
I also periodically have the joint fluid aspirated, but when I return home in the evening, the pain is particularly severe, making it almost impossible to walk.
I have to sit down to take a shower, as I cannot stand for nearly a year.
The pain has extended to my buttocks and the back of my thigh.
I have been checked for sciatica, which showed slight nerve compression, but the doctor said it does not correlate with my pain condition.
Below are the MRI report findings (this is the second report; the third report diagnosed a bucket handle tear of the meniscus):
1.
The patellofemoral joint shows fraying of the cartilage surface in the lateral patellar facet inferior pole (Se:4; Im:8).
2.
A synovial plicae is noted over the medial recess of the patellofemoral joint.
3.
A small amount of effusion with synovial thickening in the suprapatellar bursa, tibiofemoral joint, and patellofemoral joint is noted, favoring synovitis.
4.
The posterior cruciate ligament shows relatively thin fibers in the mid-distal segment.
Correlation with functional stability tests is recommended due to suspicion of insufficiency.
5.
There is no Baker's cyst or focal mass lesion in the popliteal fossa.
Clinical correlation is suggested.
Thank you for your response, Doctor.

Hello: The MRI report you provided does not mention the meniscus tear you referred to in your text.
I may need to review the images or see a third report to provide you with more insights.
On the other hand, regarding the popliteal area, the MRI indicates that there is no Baker's cyst, but it seems that the posterior cruciate ligament has a signal that is not strong enough, which you did not mention in your text.
How did your clinical physician assess the physical examination of your posterior cruciate ligament? I look forward to your reply.
Thank you, and I wish you a speedy recovery.

More Info

Chronic knee pain, particularly deep popliteal discomfort, can be a complex issue that often requires a multifaceted approach to diagnosis and treatment. Based on your detailed description and MRI findings, it seems that your knee pain has persisted for three years despite undergoing arthroscopic surgery for a bucket handle meniscus tear. The pain you experience in the popliteal region, which worsens throughout the day and is accompanied by effusion and synovitis, suggests that there may be underlying issues that have not been fully addressed.

Understanding the Pain
1. Chronic Pain Mechanisms: Chronic pain can arise from various mechanisms, including ongoing inflammation, structural changes in the joint, and even central sensitization, where the nervous system becomes more sensitive to pain signals. In your case, the presence of synovitis (inflammation of the synovial membrane) and effusion indicates that there is still an inflammatory process occurring in the knee joint.

2. Popliteal Pain: The popliteal fossa is an area behind the knee that contains important structures, including nerves and blood vessels. Pain in this area can be due to several factors, including:
- Tendonitis or Bursitis: Inflammation of the tendons or bursae can cause localized pain.

- Nerve Compression: As you mentioned, there is mild compression of the sciatic nerve, which could contribute to pain radiating down the leg.

- Joint Instability: The MRI findings suggest potential insufficiency of the posterior cruciate ligament (PCL), which could lead to instability and pain during movement.

3. Referred Pain: The pain extending to your buttocks and thigh may be referred pain from the knee joint or could indicate issues with the lumbar spine, particularly if there is any nerve root involvement.

Treatment Options
1. Physical Therapy: Engaging in a structured physical therapy program can help strengthen the muscles around the knee, improve stability, and reduce pain. A physical therapist can tailor exercises to your specific needs, focusing on flexibility, strength, and proprioception.

2. Pain Management: Since you are experiencing significant pain, a pain management specialist could provide additional options. This may include:
- Medications: Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, or neuropathic pain medications like gabapentin or pregabalin may be beneficial.

- Injections: Corticosteroid injections into the knee joint can help reduce inflammation and pain. Hyaluronic acid injections may also provide lubrication and pain relief.

- Nerve Blocks: If nerve involvement is significant, a nerve block may provide temporary relief.

3. Surgical Options: If conservative treatments fail, further surgical options may need to be considered. This could include:
- Revision Surgery: If there are structural issues that were not addressed in the initial surgery, a revision may be necessary.

- Decompression Surgery: If there is significant nerve compression, surgical decompression may alleviate symptoms.

4. Lifestyle Modifications: Weight management, activity modification, and the use of assistive devices (like braces or orthotics) can help reduce stress on the knee joint and improve function.

5. Alternative Therapies: Some patients find relief through acupuncture, massage therapy, or other complementary therapies. These can be considered as adjuncts to conventional treatment.

Conclusion
Chronic knee pain, especially with deep popliteal discomfort, can be challenging to manage. It is essential to work closely with a team of healthcare providers, including orthopedic surgeons, pain specialists, and physical therapists, to develop a comprehensive treatment plan tailored to your specific condition. Regular follow-ups and adjustments to your treatment plan based on your response will be crucial in managing your symptoms effectively. Additionally, addressing any psychological aspects of chronic pain through counseling or support groups may also be beneficial, as chronic pain can significantly impact mental health and quality of life.
