Knee Pain

The knee is the body’s hardest-working hinge, and when it hurts, everything from a morning walk to a flight of stairs turns into a negotiation. At Acupuncture Zen in Delray Beach, knee pain is one of the most common concerns patients bring through the door — whether from osteoarthritis, an old athletic injury, or the everyday wear of an active life. Dr. Tony Willcox, A.P., uses acupuncture as a complementary approach alongside orthopedic and physical therapy care, not as a replacement for it.

Knee pain is discomfort in or around the knee joint — the meeting point of the thighbone, shinbone, and kneecap, cushioned by cartilage and stabilized by ligaments and tendons. Because so many structures share such a small, heavily loaded space, pain can arise from the joint surface, the surrounding soft tissues, or referred sources such as the hip. It may be a deep ache, a sharp catch with certain movements, or stiffness and swelling that worsen with activity or with long periods of rest.

Knee pain presents in many ways, and the common contributors include:

• Osteoarthritis — cartilage wear that narrows the joint and stiffens the knee over time
• Tendinopathy, such as patellar or quadriceps tendon irritation from overuse
• Ligament or meniscus injuries from sports or sudden twisting
• Patellofemoral pain — aching around or under the kneecap, common with stairs and squatting
• Bursitis and general overuse from repetitive load

Because a painful knee can stem from a variety of problems — some requiring imaging or surgical evaluation — an orthopedic assessment is considered the right first step to ensure treatment is matched to the actual cause.

In Chinese medicine, several major meridians cross the knee, and persistent knee pain is often approached as Qi and Blood stagnation. This local blockage keeps the joint from moving and recovering freely. When the pain is worse with cold and damp weather, a ‘Bi syndrome’ pattern of obstruction may be considered, and where the knees feel weak and give out, an underlying Kidney or Liver deficiency governing the tendons and bones may be part of the picture. Treatment aims to move that stagnation, warm and free the joint, and ease the muscular tension surrounding it.

Acupuncture targets the joint and the muscles and tendons that support it, aiming to ease local tension and support the body’s natural pain-modulating response. Points are often selected both around the knee itself and along the associated meridians, and electrical stimulation is sometimes added to reinforce the effect.

For pain driven by tight or restricted muscle bands around the knee, dry needling is often used to release those trigger points as part of a broader plan.

A 2024 systematic review and meta-analysis focused on the duration of benefits last found that, for knee osteoarthritis, acupuncture may provide clinically meaningful pain relief and functional improvement for several months after a course of treatment, with a good safety profile (Chen et al., Current Pain and Headache Reports, 2024). The same review was candid that when acupuncture was added on top of exercise-based physical therapy, it didn’t clearly outperform physical therapy alone — a reminder that it works best as one part of an active, well-rounded plan.

A first visit begins with a conversation about how the pain started, what movements aggravate it, whether there’s swelling or instability, and what orthopedic or physical therapy care is already underway. Dr. Willcox will assess the knee’s range of motion and the surrounding muscle chain before choosing a point protocol — which may combine points around the knee, distal points along the involved meridians, and, where appropriate, dry needling of restricted tissue. Most patients feel a deep, dull ache or a muscle release during treatment. Relief usually builds over a series of sessions, particularly for arthritis-related pain that has developed over years.
