Knee — Deep Transverse Friction
What changes when Cyriax Deep Transverse Friction meets the knee? Start with the patient's movement, assess safely, and see what the re-test reveals.
2 specific variationsClinical re-test built in
Important: this is a clinical framework, not a complete technique protocol.
This page was generated from broader regional principles. It can help you frame assessment, patient comfort, safety and reassessment, but its generic positioning, contact and dosage text must not be treated as technique-specific hands-on instruction. Study a detailed, individually authored procedure and use supervised practical training.
Each variation below is written so you can follow patient setup, contact, direction, dose and the re-test that decides whether the technique earned a place in the plan.
01
KneePatellar tendon
Patellar Tendon — Deep Transverse Friction
One question matters more than the name of this variation: will the patient notice a useful change in Pain during decline squat or other tendon-loading task, local tendon tenderness and loading tolerance.? The careful re-test gets the final word.
The change we are looking for
Use only as a short-term adjunct for a localized, chronic patellar-tendon presentation; it is not the main treatment for patellar tendinopathy.
Primary target
Patellar tendon
The movement that tells us
Pain during decline squat or other tendon-loading task, local tendon tenderness and loading tolerance.
Patient focus
Use only as a short-term adjunct for a localized, chronic patellar-tendon presentation; it is not the main treatment for patellar tendinopathy.
Therapist verifies
Pain during decline squat or other tendon-loading task, local tendon tenderness and loading tolerance.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in pain during decline squat or other tendon-loading task, local tendon tenderness and loading tolerance. without symptom worsening.
Full clinical application
1
Position the patient
Supine or long sitting with the knee supported in slight flexion so the quadriceps can relax and the tendon is easy to palpate.
2
Set the contact
Identify the familiar symptomatic portion of the tendon—often near the inferior patellar pole. Use a fingertip or reinforced-finger contact across the tendon while stabilizing the overlying skin.
3
Apply the technique
Move strictly side-to-side across the tendon fibers with a small excursion. Do not rub longitudinally up and down the tendon.
4
Dose & re-test
Use a short, tolerable trial rather than prolonged painful friction. Reassess, then prioritize progressive tendon loading such as isometric/slow resistance according to irritability. Re-test: Pain during decline squat or other tendon-loading task, local tendon tenderness and loading tolerance.
Clinical pearl
The treatment target is a clinically identified tendon, not simply 'pain below the kneecap.' Loading progression matters far more than aggressive friction.
Safety / avoid
Avoid acute tendon tear, marked swelling/heat, recent surgery or a highly irritable reactive presentation.
02
KneeQuadriceps tendon
Quadriceps Tendon — Deep Transverse Friction
One question matters more than the name of this variation: will the patient notice a useful change in Pain with squat/step, resisted knee extension and local tendon tenderness.? The careful re-test gets the final word.
The change we are looking for
Selected adjunct for localized chronic quadriceps-tendon symptoms above the patella.
Primary target
Quadriceps tendon
The movement that tells us
Pain with squat/step, resisted knee extension and local tendon tenderness.
Patient focus
Selected adjunct for localized chronic quadriceps-tendon symptoms above the patella.
Therapist verifies
Pain with squat/step, resisted knee extension and local tendon tenderness.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in pain with squat/step, resisted knee extension and local tendon tenderness. without symptom worsening.
Full clinical application
1
Position the patient
Supine with the knee supported in slight flexion and quadriceps relaxed.
2
Set the contact
Use precise transverse contact over the symptomatic tendon just superior to the patella while avoiding direct patellar pressure.
3
Apply the technique
Small side-to-side movement across the tendon fibers.
4
Dose & re-test
Short tolerable bouts followed by graded quadriceps loading. Re-test: Pain with squat/step, resisted knee extension and local tendon tenderness.
Clinical pearl
Differentiate quadriceps tendon pain from patellofemoral pain before treating the tendon.
Safety / avoid
Avoid acute tear or reactive inflammatory flare.
Safety / do not apply when…
Avoid routine manual therapy with suspected DVT, fracture, acute instability, infection or uncleared postoperative restriction.
Stop or modify if symptoms peripheralize, neurological status worsens, the response is disproportionate or the patient asks to stop.
Clinical rule
A technically correct technique is not automatically a useful technique. Keep it only when the patient's pain, range or function improves in a clinically meaningful way, then transfer that gain into active movement, loading or self-management.
