But what if, for some runners, the tendon itself isn’t the main driver of pain anymore?In this episode, Brodie breaks down a new 2026 systematic review that may reshape how we think about stubborn, long-standing tendon pain. The paper explores whether nerve ingrowth and abnormal blood vessels around tendons — not degeneration of the tendon tissue itself — may be the real pain source in chronic cases.We unpack the emerging research, explain each intervention in plain language, and discuss who this may (and may not) apply to — especially runners stuck in repeated rehab cycles despite “doing everything right.”This is early, evolving science. But it’s a fascinating glimpse into where chronic tendon treatment may be heading next.What You’ll Learn in This EpisodeWhy some chronic tendon pain may be neuropathic (nerve-driven) rather than structuralHow abnormal blood vessels and nerves grow into painful tendons over timeWhy traditional loading programs sometimes stop working in very chronic casesWhat “neural modification” treatments aim to do — and why they’re gaining interestThe six intervention categories reviewed in the paper (explained simply)How strong (or limited) the current evidence actually isWhere this research fits alongside exercise-based rehab, not against itInterventions Reviewed (Plain-English Overview)1. High-Volume Injections (HVIGI / HVDI)Large volumes of fluid are injected around the tendon (not into it) under ultrasound guidance to mechanically disrupt abnormal blood vessels and pain-sensitive nerves.Key takeaway: Consistent short- to medium-term pain and function improvements, especially in people who had failed exercise-based rehab.2. Sclerosing Polidocanol InjectionsA chemical agent is injected directly into abnormal blood vessels to deliberately close them down, cutting off blood supply to pain-producing nerves.Key takeaway: Moderate to strong pain reductions in very chronic cases, with outcomes comparable to surgery in some studies.3. Radiofrequency MicrotenotomyA minimally invasive procedure using controlled heat to disrupt nerve ingrowth and abnormal vessels at the tendon–paratenon interface.Key takeaway: Very strong results in a small cohort, but higher risk and limited evidence so far.4. Minimally Invasive Paratenon ReleaseScar-like adhesions between the tendon and surrounding tissue are mechanically released to restore tendon movement and reduce nerve irritation.Key takeaway: Large pain reductions and high rates of pain-free outcomes in non-insertional Achilles tendinopathy.5. Electrocoagulation TherapyElectrical energy is used to seal off abnormal blood vessels surrounding the tendon under ultrasound guidance.Key takeaway: Promising early results, but evidence limited to one small study.6. Surgical Interventions (Open & Endoscopic)Surgery physically separates the tendon from irritated surrounding tissue and removes abnormal vessels and nerves.Key takeaway: Effective for some, but invasive, with longer recovery and higher risk.The Big Picture TakeawayAcross very different procedures, outcomes were surprisingly similar.That points to a common mechanism: 👉 Modifying the neural (nerve-driven) pain environment around the tendon, rather than “fixing” tendon structure itself.This doesn’t replace exercise-based rehab — but it may explain why a subset of runners with long-standing, highly sensitive tendinopathy stop responding to load alone.This research is best viewed as a future direction, not a replacement for good rehab principles.

The result is a balanced, evidence-informed discussion that helps runners understand where surgery fits — and where it doesn’t.What You’ll Learn in This Episode:How Surgeons Decide Who Actually Needs SurgeryWhy MRI findings alone are never enoughThe importance of correlating scans with clinical function and symptomsWhy some complete avulsions heal well conservatively — and others don’tHamstring Avulsion vs Proximal Hamstring Tendinopathy (PHT)Key differences between acute avulsions, chronic avulsions, and tendinopathyWhy not all “avulsions” are the same (1-tendon vs 3-tendon injuries)When retraction distance matters — and when it doesn’tCritical Timing WindowsWhy acute avulsions should ideally be operated on within 2–3 weeksWhat happens when diagnosis is delayedWhen chronic injuries become harder (or impossible) to fully restore surgically“Failed Rehab” — What That Really MeansWhy many runners are told they’ve “failed rehab” when they actually haven’tCommon mistakes in conservative treatment (under-loading, poor progression)When even excellent rehab is unlikely to succeed due to tendon biologyWhat Surgery for PHT Actually InvolvesWhat surgeons look for during surgery beyond “tendon thickening”The role of semi-membranosus release, scar tissue, and sciatic nerve involvementWhy surgeons often find structural issues not obvious on standard MRICommon Pre- and Post-Op MistakesWhy under-diagnosis is one of the biggest pre-op risksWhy returning to running too early post-op leads to setbacksThe importance of fixing why the injury happened — not just repairing tissueKey TakeawayMost hamstring injuries — including many cases of PHT — can and should be treated conservatively. But there is a subset of runners where surgery is not only appropriate — it’s the missing piece.This episode helps you understand which group you fall into, without fear-based decisions or false hope.

You’ll learn how healthy tendons are structured, what changes at a microscopic level when tendinopathy develops, and why pain severity often doesn’t match what shows up on scans. The episode explores how factors like load management, low-grade inflammation, oxidative stress, ageing tendon cells, and overall metabolic health all interact to influence tendon pain and recovery. Brodie also discusses what this emerging science means for real-world rehab — including why rest alone doesn’t work, why exercises sometimes stall progress, and why a more holistic approach is often needed. The episode finishes by looking ahead at future treatment directions, from improved diagnostics to regenerative and molecular therapies, while grounding everything in practical takeaways runners can apply right now. If you’re dealing with persistent tendon pain — especially proximal hamstring or Achilles tendinopathy — this episode will help you understand why recovery can be slow and what actually gives you the best chance of long-term success.

Stronger Hamstrings = Better Running MechanicsAthletes with higher eccentric hamstring strength had:Higher stride frequency (cadence)Better control of decelerating the swinging legLower ground contact time (improved efficiency)Lower hamstring activation at sub-max speeds → reduced overload 2. Longer Hamstring Fascicles = Safer, More Efficient LoadingRunners with longer fascicle lengths showed:Less anterior pelvic tiltLower hamstring activationBetter ability to tolerate late-swing loading (a high-irritation phase for PHT) 3. A Two-Way Relationship ExistsStrength ↔ mechanics influence each other.Stronger hamstrings → better running techniqueBetter running technique → better hamstring loading → stronger, longer muscle structure over time This creates a positive adaptation loop. 4. Over-Reliance on the Biceps Femoris = Red FlagRunners with weak or short hamstrings tended to over-activate the biceps femoris long head — the most common site of PHT. Stronger runners shared load better with the medial hamstrings, reducing tendon stress. 🏃 Practical Rehab Takeaways1. Build Eccentric StrengthEccentric strength is one of the strongest predictors of hamstring injury risk. Examples Brodie recommends:Hamstring slidersWeighted eccentric slidersSingle-leg slidersAssisted → full Nordic dropsDeadlifts (when tolerated) 2. Improve Fascicle LengthEccentric exercises at long muscle lengths help lengthen fascicles naturally — more so than stretching alone.3. Strengthen the Medial HamstringsTo prevent overload of the biceps femoris:Use toes-in hamstring curlsToes-in slidersToes-in deadlift variations These help redistribute load more evenly across the tendon. 4. Slightly Increase Cadence (~5%)A small increase in stride frequency may reduce late-swing strain and improve running economy.5. Integrate Running Into RehabBefore adding speed:Build to 30 minutes continuous, easy running → symptom-free Then introduce:Strides (15–20 sec at ~75% speed, 4 reps)Gradual progression based on symptoms the next day Final ThoughtsHamstring strength, muscle architecture, and running technique are deeply interconnected. Improving one helps improve the others — creating a pathway toward better performance and long-term PHT resilience.
