When the Knee Wasn't the Source of the Pain

He Suffered from Knee Pain for Years… But the Real Problem Wasn't His Knee

Pain is not always caused by the area where it is felt. This case demonstrates how an accurate diagnosis can reveal the true source of pain and guide the most appropriate treatment.

A patient visited Dr. Mohamed Koura's Center for Spine and Joint Pain Management after years of severe knee pain that had significantly affected his mobility and quality of life.

Over the years, he had consulted multiple pain management physicians and orthopedic surgeons. He underwent several therapeutic knee injections and even received radiofrequency treatment for the knee, but each treatment provided only temporary relief before the pain returned.

Looking Beyond the Knee

When the patient arrived at our center, the evaluation did not begin with selecting another procedure or reviewing imaging alone. Instead, it started with a detailed medical history, a careful discussion of his symptoms, a comprehensive physical examination, and a thorough review of his imaging studies.

The clinical findings suggested that the previous diagnosis did not fully explain the patient's symptoms.

The Diagnosis

The patient did have knee osteoarthritis, but it was not the primary cause of his severe pain.

The actual diagnosis was lumbar foraminal stenosis at the L3-L4 level, where narrowing of the neural foramen compressed the L3 nerve root. Because this nerve supplies sensation to the front of the knee, the pain was referred to the knee, making it appear as though the knee joint itself was the source of the problem.

In other words, previous treatments had focused on the location of the pain rather than its underlying cause.

The Treatment Plan

After discussing the diagnosis with the patient, a treatment plan was developed to address the true source of the pain.

A Rimming endoscopic foraminal decompression was performed. This minimally invasive procedure enlarges the narrowed neural foramen, relieves pressure on the affected nerve root, and restores normal nerve function without the need for open spine surgery.

The procedure was completed successfully.

Within a short period, the patient's pain improved significantly. He was able to walk more comfortably, resume his daily activities, and avoid the spinal surgery he had believed would eventually be necessary.

Why This Case Matters

This case highlights the importance of an accurate diagnosis before treatment begins. Although the patient had knee osteoarthritis, it was not responsible for his primary symptoms.

In some patients, knee pain may actually originate from the lumbar spine due to nerve compression rather than the knee joint itself. Careful clinical assessment is essential to identify the true source of pain and determine the most appropriate treatment plan.
