Happy Friday {{first_name}}!! I hope you had an amazing labor day weekend! Do me a quick favor and share this email with two colleagues of yours! Just hit the fwd button, so they also level up this weekend.
The Case:
M is 24. Club volleyball middle blocker, three clinicians in five months, and he walked in with a folder. Never had this happen before, but it wasn’t a great sign. His pain started in April, two weeks after his team added a second weekly jump block. By June it was sharp and focal below the kneecap: worst on the first few jumps, gone once he is warm, back hard about an hour after he finishes, and stairs the next morning are the worst part of his day.
He rested four weeks in July. Felt great by week three. Went back to full practice and was worse than baseline in eight days.
The Trap:
Most clinics call it patellar tendinitis, rest it, and return the athlete to full sport volume the moment pain resolves. And here is the cruel part — it works. Pain reliably improves with rest, because rest removes the mechanical stimulus provoking a sensitized tendon. The athlete feels better. Everyone declares victory. Then he jumps again and it comes back worse, because during those four weeks his tendon, quadriceps, and calf all lost capacity while his sport demand stayed exactly where it was. He did not return to the gap that injured him. He returned to a wider one. The second version of this trap shows up in better clinics: the clinician knows the research, prescribes eccentric decline squats, hands over a printout. Three sets of fifteen, twice daily, twelve weeks. No staging. No question of whether the tendon is currently reactive or degenerative. Same exercise, very different tissue, completely different result.
The Workup
Royal London Test — positive. Inferior pole tenderness present in extension, gone with the knee flexed. This localizes the symptom generator to the tendon itself rather than the fat pad or retinaculum. Cheap, fast, and it keeps you from treating the wrong structure with the right protocol.
Single leg decline squat — positive, 4/10 familiar pain. This is your load test and your outcome measure in the same movement. The number you get on day one is the number you track for twelve weeks. If you are not recording it, you have no progression criteria — you have a calendar.
24-hour pain response — positive for reactive overlay. Morning stiffness over 30 minutes after loading days, pain up the day after a full practice. Latent aggravation is the single best clinical marker that a tendon is currently reactive. It does not change whether you load. It changes where you start.
Hoffa test and bone stress screen — both negative. No fat pad pain at end-range extension, no night pain, no rest pain, no focal bony tenderness, non-provocative single leg hop. Negative here clears the pathway for progressive loading. Positive here stops the program and starts a referral, because bone stress shares the same neighborhood, the same athlete, and the same load-spike mechanism.
Single leg heel raise capacity — 9 right, 22 left. Calf capacity drives energy absorption at landing. A deficit that size means the patellar tendon is absorbing force the ankle should be sharing. Test this on every lower limb tendinopathy, no matter which tendon hurts.
A REACTIVE tendon is swollen, irritable, acutely overloaded. When you load it hard you make it angrier. A DEGENERATIVE tendon has compromised regions surrounded by healthy tissue that will absolutely respond to load. Under-load it and it never improves. Most athletes symptomatic for months are both. Degenerative core, reactive flare on top.
Now, are you following? You cannot program a tendon until you stage it.
The Plan
Foundation: Start with isometrics, not rest. They give you an analgesic window and load the tendon without the energy-storage demand that provokes a reactive one. Cut provoking sport volume roughly in half, hold all plyometrics, and use the isometric hold as a primer before practice. Exit on a decline squat number and a morning stiffness threshold — not on a date.
Loading: Heavy slow resistance, and genuinely heavy. Slow tempo, high load, low reps, through range, three sessions a week with 48 hours between. Rebuild the calf in parallel, because the soleus is your primary energy absorber at landing. If your athlete finishes the last rep as fast as the first, the load is too light and you just wasted a training block.
Sport-specific: Add rate before you add sport. Fast concentric work first, then low-amplitude contacts with the count logged, then true energy storage (hops, depth work, and a built approach progression) never on consecutive days. This is the stage everyone skips, and skipping it is exactly why athletes get cleared and re-injure in three weeks.
The whole program runs on the pain-monitoring rules: pain during loading up to 5/10 is acceptable, it must return to baseline in 24 hours, and morning stiffness cannot be worse than the previous morning. Break rule two or three and you hold the load. You do not regress. You just stop advancing.
Clinical pearl: Pain that improves with rest and returns worse on re-entry is not a treatment failure — it is a capacity problem wearing a pain costume.

The Practice
The Performance Doctor: Three things in this case make you money, and none of them are an exercise.
The first is the honest timeline. M asked at visit one how long this would take. The real answer was three to six months. He had a showcase in ten weeks. There is real pressure to shave that number down to earn business. It keeps the athlete engaged, it keeps him rebooking, it avoids a hard conversation on day one. It is also a relationship built on something untrue. An athlete who understands why week 8 matters will train through week 8. An athlete who was promised week 6 quits in week 7 and tells his teammates you did not help.
The second is translation. M's club coach called wanting to know if he could play through it at reduced minutes. Reduced minutes is not a load reduction the way coaches think. Volume drops, intensity does not. So do not say "no volleyball." Say "no blocking, no attacking, back row only, 40 total jumps per week logged." That is a restriction a coach can actually implement, and it buys you a referral source instead of an adversary.
The third is the plateau. Around week 9 or 10 most tendinopathy athletes stall out. Better, not gone, improved, not symmetrical. It is the easiest point in the case to keep booking two visits a week, because the athlete still has symptoms and still wants help. Ask yourself honestly whether he needs your hands or your program. At week 10 it is almost always the program, and the program runs fine on a check-in every three weeks.

Dropping visit frequency when the clinical picture supports it is not lost revenue. It is what makes that athlete refer his entire team to you two years from now.
Every patient is unique. Every tendon tells you what it needs if you test it instead of guessing.
In health and strength,
