A friend recently asked me for some advice when we were out at dinner. He said he was getting sharp lateral knee pain - so much so that he couldn't kneel anymore to play with his boys on the floor.
My McKenzie method training emphasizes determining which activities make the symptom worse (or produce the symptom) and which activities make the symptom better, so I asked him some questions. He related that the symptom of pain is produced ONLY with kneeling. He is able to walk, jump, and even play basketball without any problems.
I admit, years ago, before I became more skilled at the McKenzie method, his verbal history would have seemed non-informative at best, perplexing at worst. Now, however, his history screams one thing at me: SPINE! It seems that when his lumbar spine is extended his knee is fine and when his lumbar spine is flexed (kneeling sitting on his heels) his knee hurts.
I assessed the knee: full, painless extension and flexion with passive overpressure. I then looked to "clear the spine." I tested his lower extremity myotomes: deficits. I tested his lumbar spine mobility: deficits. We moved his lumbar spine repeatedly into end-range extension - first without pressure and then with overpressure - and tested his kneeling ability. Much better.
His home exercise program is repeated lumbar extension to end-range with overpressure and posture correction. He, of course, also has to temporarily avoid activities of sustained lumbar flexion. We will see if this exercise achieves full resolution of his symptom; we may have to move his spine in a different direction. It is clear, however, that his spine is involved. And my experience leads me to hypothesize that his spine is the only structure at fault here, which should be rapidly fixable using the the McKenzie method.
"Clearing the spine" is of the utmost importance. I have written about this before. The spine is involved in almost every orthopedic issue to at least some degree. (The spine also plays a role in seemingly "non-orthopedic" pathology.) I implore clinicians treating orthopedic pathology to learn how to do it effectively so that they don't miss all of these diagnoses like I used to. -- Laura
