Why rest and a knee support have not fixed it.
Most knee pain is a load problem. The knee is asked to do more than it is ready for, often because the hip, the ankle or a jump in training is passing extra work to it. Rest calms it, then it flares the moment you go back. What changes it is finding where the load comes from and building the knee back up, with someone checking it is working. That is what the programme is for.
The Achilles Method: one practitioner, three phases.

We find what is overloading the knee, looking from the hip down to the foot.

Tension Release
Hands-on treatment to settle the thigh, the calf and the tissue around the knee.

Strength Rebuild
A loading plan written for you, so the knee can take your training again.
Your plan is explained in the room and given to you in writing.

Questions before you book.
About the programme
Can I book the whole programme now?+
Yes. Book it online and your first session is The Cornerstone. If the assessment shows the programme is not right for you, we refund everything except the assessment. You can also cancel within 14 days of booking and pay only for the sessions you have used. Prefer to meet first? Book The Cornerstone on its own, and if you go ahead the £120 comes off the programme.
Do I have to stop training?+
Usually not. Stopping completely tends to lower what the knee can take, so it flares again when you go back. We agree what your knee can handle at your assessment and adjust your running or your leg sessions around it, so you keep training while it settles.
How long does it take?+
The programme usually runs over eight to ten weeks. Your assessment sets the length for your knee, and you leave with the plan to carry on.
What if it is not working?+
If it is not moving, the plan changes, or we refer you on.
Is Alexander a physiotherapist?+
No. Alexander is an ISRM Level 5 Soft Tissue Therapist, not a registered physiotherapist. Physiotherapy on this site describes a type of service, not a registration. If your case needs a registered clinician or a doctor, we tell you and refer you.
Can I claim on health insurance?+
We do not work with private medical insurers. We provide a full receipt and a paid invoice for every session, so if your policy or health cash plan reimburses treatment, you can claim it back yourself.
About knee pain
What is causing my knee pain?+
In active people the most common cause is pain around or behind the kneecap, often called runner's knee (patellofemoral pain). It hurts most when the knee takes load while bent: stairs, squats, hills and sitting with the knee bent for long periods. Other causes include a sore tendon just below the kneecap, common in jumping and heavy leg training, pain on the outside of the knee linked to the IT band, and wear in the joint. Your assessment tells us which you have before a single exercise is set.
Is it my knee or my hip?+
Often both. Weak hips, stiff ankles or the way you land can pass extra load to the knee. That is why the assessment looks from the hip down to the foot, not only at the knee.
Do I need a scan first?+
Usually not. Scans often show changes that are just as common in people with no knee pain at all. Imaging helps after a significant injury, when the knee locks or gives way, or when progress stalls, and we will tell you if yours is one of those.
Should I wear a knee support or strapping?+
If it makes you more comfortable, that is fine for now. It does not change what the knee can take. Building strength does, and that is what the programme is for.
Who gets it?+
Runners, people who squat and lunge in the gym, cyclists, and anyone who has stepped up quickly: a new running plan, a hiking holiday, or a move to a flat with more stairs. We see it at both clinics, in Kings Cross and in Hampstead, and the assessment and the programme are the same at each.
When does knee pain need a doctor?+
Go to A&E or urgent care if you heard a pop or felt the knee give way and it swelled within hours, if you cannot put weight on it, if it is locked and will not straighten, or if it is hot, red and swollen and you feel unwell or feverish.
See your GP first if the knee swells without an injury, if pain wakes you at night and does not ease with rest, or if knee pain comes with pain in several other joints. We screen for all of these at your assessment and refer you on if your case needs it.
