Proximal Hamstring Avulsion: Surgery vs Conservative Rehab in a Shared Decision Model

Jun 2

Quick answer (for when you're panicking)

If you’ve just been told you have a proximal hamstring rupture or avulsion and you’re stuck on “Do I need surgery or can I rehab this?”, it can feel like one wrong choice will ruin your future.

Two good news pieces from recent research:

In two prospective studies (van der Made et al, 2022, Spoorendonk et al, 2024) using a proper shared decision‑making model, both surgery and conservative rehab led to similarly good outcomes at 12 months for many adults with proximal hamstring avulsions.
Conservative treatment, when done seriously and phase‑based, did far betterthan most people expect. It is not the “giving up” option.

That does not mean surgery never matters. It means the decision is more about your specific tendon pattern, timing, sport demands, and preferences than about a simple “surgery good, rehab bad” story.

What these two studies actually did

Both research groups in Denmark (Spoorendonk et al, 2024) and the Netherlands (van der Made et al, 2022) followed a very similar pattern.

First, they only included people with MRI‑confirmed proximal hamstring avulsions (one to three tendons pulled off the bone at the sitting bone).

Second, they did not randomise people blindly. Instead, they used a shared decision‑making model:

The clinician explained the diagnosis, anatomy, pros and cons of surgery and of conservative rehab, and realistic expectations.
The patient’s age, sport level, number of tendons involved, amount of retraction, time since injury, and preferences were taken into account.
Together they chose surgery or conservative care, then everyone followed a structured rehab programme.

Third, they followed people for about a year and measured:

PHAT scores (Perth Hamstring Assessment Tool, 0–100, higher is better)
Sport activity level
Strength differences between legs
In the Dutch study, follow‑up MRI to see if the tendon had re‑attached (continuity)

So these are not random “stories.” They’re structured follow‑ups of real patients making real choices.

What they found (in plain language)

In both studies, patients started in different places.

Surgical patients tended to have:

More tendon retraction
More tendons involved
Worse function and more symptoms at baseline
Shorter time from injury to first consult

Conservative patients tended to be:

Slightly later in the timeline
Often with somewhat less retraction or fewer tendons involved
Still clearly limited, but not always as severe on paper

Despite that, at 12 months:

PHAT scores were very similar between surgery and conservative groups (around 75–80 out of 100 in both Spoorendonk and van der Made).
Both groups showed clinically meaningful improvements in pain, sitting tolerance, walking, and function.
Strength deficits between legs narrowed in both groups, especially for hip extension.
A solid number of patients in both groups were back to sport, though not everyone returned to their full pre‑injury level within a year.

The Dutch group added MRI at 1 year:

Almost all surgical patients (about 95–100% without reinjury) had clear tendon continuity again.
About half of conservatively treated patients also showed a “neotendon” bridging back to the bone.
Clinical outcomes (PHAT, function, quality of life) were still comparable, even though the imaging looked different.

Put simply: in middle‑aged, mostly non‑elite populations using shared decision‑making and real rehab, both surgery and conservative care can land you in a similar functional place after 12 months.

What this does not mean

It does not mean surgery is pointless. There are still clear situations where surgery is usually favoured, especially in:

Young, high‑demand or elite athletes
Complete three‑tendon avulsions with large retraction
Clear sciatic nerve symptoms or very high functional loss

It also does not mean conservative care is always “just as good.” These were relatively small cohorts, and long‑term (5–10 year) differences are still being studied.

What these studies really kill is the old myth that:

“If you don’t repair it, you’re doomed” for every adult with a proximal hamstring avulsion.

The data do not support that blanket statement.

How to use this if you’re the injured athlete

Instead of asking “Which path is the right one for everyone?”, you can start asking more useful questions with your team:

“Given my age, sport, tendons involved, retraction, and time since injury, where do I sit compared to the patients in these studies?”
“What would good 12‑month outcomes look like for me in real life: sitting, work, sport, confidence?”
“If we go conservative, do we have a serious, phase‑based rehab plan like the ones used in these studies?”
“If we go surgical, what is the realistic complication risk in my world, and what is the plan if I’m not where we hoped at 6–12 months?”

You can literally bring PHAP and UPHAG to your consult, plus a short list of questions:

“Do you think I’m closer to the cases that did well with surgery, or to the ones that did well with conservative care in these newer studies?”
“If we start with conservative rehab for a few weeks, how will we decide whether that route is working or whether we should reconsider surgery?”

The goal is not to win an argument. It is to design a decision you will not regret if you read these same papers in two years’ time.

How to use this if you’re a coach or clinician

For clinicians, these studies support something many already feel in their gut: there is clinical equipoise in a lot of proximal hamstring avulsion cases. That is exactly where shared decision‑making belongs.

Pointing to Spoorendonk and van der Made allows you to say, calmly:

“We have emerging prospective data showing good 1‑year outcomes with both surgery and conservative treatment when we choose carefully together and take rehab seriously.”
“Because of that, this is not a simple ‘must operate’ vs ‘must avoid surgery’ situation. Your preferences, your sport, and your risk tolerance matter.”

For coaches, this gives you language to support your athlete without forcing one direction:

“We know from newer studies that a lot of adults do well at a year whether they go surgery or serious rehab, if the plan is solid.”
“My job is to protect you from being rushed back just for optics. Let’s listen carefully to what your surgeon and physio recommend and then commit fully to that lane.”

Final thoughts

Proximal hamstring ruptures and avulsions sit in an uncomfortable space: rare, painful, slow to rehab, and deeply tied to how you see yourself as an athlete. That is exactly where scary stories and oversimplified advice thrive.

The most honest thing we can say today, looking at these studies, is this:

For many middle‑aged, non‑elite athletes, both surgery and conservative treatment can lead to good 12‑month outcomes when chosen through a shared decision‑making process and backed by structured rehab.
The choice is less about finding the one “correct” path for everyone and more about matching your specific injury and life to the lane that gives you the best chance to be functional, confident, and proud of how you handled this chapter.

You are allowed to ask hard questions.
You are allowed to want more than “just pick something.”
You are allowed to say, “I want a decision I can live with in two years, not just a quick exit from today’s fear.”

Who this actually affects (beyond you)

A decision between surgery and conservative rehab for a proximal hamstring rupture/avulsion never lives only in your head.

When you are stuck between “operate” and “try rehab,” the uncertainty spreads through a small system around you. Not because anyone is doing a bad job, but because this injury sits in a genuine grey zone where urgency is often emotional rather than purely medical. Feeling paralysed, afraid of regret, or worried about “missing the window” is a normal reaction when the stakes feel high and the timelines are not crystal clear.

That tension lands differently on each person:

You, the athlete: carrying the fear that waiting could cost you performance or options, and acting could lead to regret if it doesn’t help.
Your surgeon or sports physician: weighing imaging, tendon retraction, age, sport level, and complication risk, without living inside your daily fear.
Your physio: trying to keep rehab moving and collect real data on function while the long‑term route is still open.
Your coach or employer: needing some sense of planning, even when perfect predictability is impossible.
Your partner or close support person: watching you live in limbo and wanting clarity, but not wanting to push you into a choice.

Instead of carrying that alone, you can use it to shape better conversations.

With your surgeon or sports physician, you can ask:
“Where do you see my case on the spectrum between clear‑surgery, clear‑conservative, and true grey‑zone?”
“If we give ourselves a few weeks of structured rehab, what realistically changes in our decision, and what probably won’t?”

With your physio, you can ask:
“Which changes in strength, pain, or function over the next weeks would actually influence the surgery vs rehab call?”
“How can we keep these sessions purposeful while the final path is still being decided?”

With your coach or employer, you can ask:
“What do you need from me so you can plan honestly without rushing me into a medical decision?”

With your partner or close support person, you can ask:
“What feels hardest about this waiting phase for you, and how can we talk about it without turning every day into a verdict?”

Framing it this way doesn’t remove the difficulty. It turns a lonely, silent burden into a shared, structured problem that you and your team can walk through together.

When you’re stuck on the surgery‑versus‑rehab decision, it can feel like everything depends on one irreversible choice.

If you hold onto that standard, and you use tools like UPHAG, PHAP, and proper shared decision‑making with your own team, you are already doing what the best athletes do in a grey zone: treating your body like a long‑term asset, not a short‑term headline.

In the background, though, most athletes are also quietly wondering whether they really understood their MRI and what life will feel like on the other side of this decision. Seeing the diagnosis, the decision, and the recovery as one connected storyline often makes the grey-zone feel less paralysing. It turns a single terrifying fork in the road into a sequence of smaller, understandable steps that you and your local team can walk through together. If that’s the kind of structure you’ve been missing, the guides can help you zoom out, steady your footing, and then move forward with more confidence.
