Knee Pain: Don't Forget Popliteus

Posted by Stuart Hinds on

Stuart Hinds explains the importance of popliteus trigger points when assessing and treating "Runner's Knee"

 

Trigger points in the popliteus are often associated with knee pain and too often, overlooked

[Latin: poples, ham]

The tendon from the origin of the popliteus lies inside the capsule of the knee joint.

ORIGIN

Lateral surface of lateral condyle of femur. Oblique popliteal ligament of knee joint.

INSERTION

Upper part of posterior surface of tibia, superior to soleal line.

 

Popliteus - Common Trigger Point Site

 

ACTION

Laterally rotates femur on tibia when foot is fixed on ground. Medially rotates tibia on femur when leg is not weight bearing. Assists flexion of knee joint (popliteus “unlocks” extended knee joint to initiate flexion of leg). Helps reinforce posterior ligaments of knee joint.

NERVE

Tibial nerve, L45, S1.

BASIC FUNCTIONAL MOVEMENT

Example: walking.

TRIGGER POINT REFERRED PAIN PATTERNS

Localized 5–6 cm zone of pain (posterior and central knee joint), with some spreading of diffuse pain, radiating in all directions, especially inferiorly.

Popliteus - Typically refers pain to the back and middle of the knee.

 

INDICATIONS

Pain in back of knee squatting/ crouching/walking/running, pain behind knee/calf walking uphill and descending stairs, stiff knee on passive flexion/extension, plantar fasciitis, chronic calf shortening, low back pain, leg cramps.

CAUSES

Post-fracture, splinting, poor orthotics, prolonged driving, twisting sports (e.g. soccer, climbing, skiing, baseball, football), associated with many knee problems.

DIFFERENTIAL DIAGNOSIS

Avulsion. Cruciate ligaments (instability). Baker’s cyst. Osteoarthritis. Tendonitis. Cartilage (meniscus) injury. Vascular (deep vein thrombosis, thrombosis). Tenosynovitis.

CONNECTIONS

Hamstrings (biceps femoris), gastrocnemius (ligamentum patellae), plantaris.

  • Great content! I had an osteopath recently identify this muscle as a potential cause of the pain, or at least inhibitor to rehabilitation from a two-year long PFPS battle now, and following a loosening of it, the pain really subsided temporarily, though this had coincided with some vascular occlusion training during which I felt some (previously missing) VMO activation. Interesting to note, as you say, this muscle is often not addressed and my experiences certainly support this.

    Are there any strengthening exercises that need or should be performed for the muscle or related issues or is this simply a releasing?
