What is a proximal hamstring tear?
The hamstrings are the three muscles along the back of the thigh. At the upper end, their tendons attach to the sit bone, the bony point you feel when you sit on a hard chair. “Proximal” means the end closest to the hip.
A proximal hamstring avulsion means one or more of those tendons has pulled off the bone. This is different from a common hamstring strain in the middle of the muscle. Strains are far more frequent and usually heal with rehab.
An avulsion often happens when the hip is forced to bend while the knee is straight. Examples are slipping with one leg sliding forward, or being pulled up while water skiing. It affects athletes, and it also affects people who were just walking on ice.
How do I know if I have one?
Common signs are a sudden pop or sharp pain high in the back of the thigh, trouble walking, and pain when sitting. Bruising may spread down the back of the thigh over the next days. Some people feel weak or unsteady, as if they can’t control the leg when stepping forward.
The large sciatic nerve runs close by. Numbness, tingling, or pain shooting down the leg should be mentioned right away.
An MRI shows how many tendons are torn and how far they have pulled back. Those details shape the discussion that follows.
Do I need surgery for a proximal hamstring tear?
Not always. This is an area where the evidence has changed.
For years, repair was the usual advice for a full avulsion, based on studies with no random assignment. A 2018 review of 795 avulsions found that people who had repairs did better on satisfaction (90.81% vs 52.94%) and strength (Bodendorfer, 2018). But the non-surgical group was very small, and most of the studies were of low quality.
A later randomized trial looked at this directly. It enrolled 119 people aged 30 to 70 at 10 centers in Sweden and Norway. At two years, function scores on a 100-point scale were 79.9 after surgery and 78.5 without it. Non-surgical care was found to be no worse than surgery. There were nine adverse events in the surgery group and three in the non-surgery group (Pihl, 2024).
That trial is the strongest study so far, but it does not settle every case. It did not include people under 30 or over 70. It also can’t tell you what is right for one person’s tear, job, or sport.
When is repair considered?
Repair may be part of the conversation when:
- You are younger or very active, especially in sprinting or jumping sports
- You feel weak or unstable, or can’t trust the leg
- Tendons have pulled well away from the bone
- Non-surgical care has not gotten you where you need to be
These are reasons to discuss surgery, not automatic reasons to have it. Partial tears are often treated with rehab first. In surgical studies, return to sport was 84.5% at an average of 6.5 months, and 92.6% of patients were satisfied (Hillier-Smith, 2022). Those studies looked only at people who had surgery, so they can’t show how the same people would have done without it.
Why does timing matter?
Tendons that have pulled away can scar down and shorten over time. If you and your surgeon decide on repair, doing it sooner is usually simpler than doing it later.
Reviews support this. Repairs done soon after injury had better satisfaction (95.48% vs 83.79%) and less pain than repairs of older injuries (Bodendorfer, 2018). A second review found faster return to sport, fewer repeat tears, and less sciatic nerve trouble with early repairs (Hillier-Smith, 2022).
A French study of 740 repairs had a repeat tear rate of 4.59%. Waiting longer than 32 days from injury was linked to a higher risk (Lefèvre, 2024). The 32-day cutoff was only a modest predictor, and it does not mean a tear is unfixable on day 33. Delayed repairs can still help.
The practical message is to get an MRI and an opinion early, ideally in the first couple of weeks. That is a reason to be seen soon, not a reason to rush into surgery. You still have time to make a calm decision.
What are the risks of surgery?
Repair is usually done through an incision near the crease of the buttock, with anchors placed in the sit bone. Risks include infection, blood clots, wound problems, irritation of the sciatic nerve, a repeat tear, and ongoing pain or weakness. Complications were reported in 23.17% of cases in one review (Bodendorfer, 2018). Results vary from person to person, and no surgeon can promise a certain outcome.
Should I get a second opinion?
It can help if you were told you must have surgery, or told it is too late. It is also useful if you are not sure whether non-surgical care fits your goals. Here’s how a second opinion works.
Where can I see Dr. Pareek?
Dr. Pareek sees patients with hamstring injuries at HSS in New York and at HSS in New Jersey. Bring any MRI images and reports you already have, and the date of your injury.
What does recovery look like?
These are typical ranges. Your surgeon’s plan comes first, and recovery varies from person to person.
- Weeks 0-2: Protect the repairAfter a repair, most people use crutches. Limits on bending at the hip with the knee straight protect the stitches. Some surgeons also use a brace. Sitting may be uncomfortable at first.
- Weeks 2-6: Start gentlyPhysical therapy begins with careful movement and light muscle work. Weight on the leg builds up as your plan allows.
- Weeks 6-12: Walk normallyMost people are off crutches and back to a normal walking pattern. Gentle strength work for the hamstring and hip starts to build.
- Months 3-6: Build strengthTherapy moves toward harder strength and balance work, then light running if your leg is ready.
- Months 6 and beyond: Return to sportMany people return to sport in this window once strength and testing allow. If you are treated without surgery, therapy follows a similar path without the early limits. These are typical ranges, and your surgeon's plan governs.
