Hamstring Reconstruction
What is Proximal Hamstring Reconstruction?
Proximal hamstring reconstruction is a surgical procedure used to repair or rebuild severely damaged or torn hamstring tendons where they attach to the pelvis (at the ischial tuberosity, commonly called the “sit bone”).
The hamstring muscles (back of the thigh) are connected to the pelvis by tendons. In serious injuries, especially complete tears or avulsions where the tendon pulls away from the bone, simple repair may not be possible. Reconstruction uses grafts (either from your own body or donor tissue) to restore the tendon structure and function.
When is Proximal Hamstring Reconstruction Recommended?
Proximal hamstring reconstruction is recommended in situations where the hamstring tendons are too damaged to be repaired directly or have failed to heal properly. This typically includes:
- Complete tendon tears, especially involving two or more hamstring tendons
- Chronic injuries where the tendons have retracted significantly over time
- Failed previous hamstring repair surgery
- Persistent pain, weakness, or loss of function despite conservative treatment (rest, physical therapy)
- High-demand individuals or athletes needing full strength and mobility
In these cases, reconstruction using a graft helps reduce pain, restore tendon function, and improve mobility.
How Should I Prepare for Proximal Hamstring Reconstruction?
Preparation for proximal hamstring reconstruction includes a thorough medical evaluation, imaging tests like MRI, and reviewing medications. Patients may need to stop blood thinners and smoking. Fasting before surgery is required. Preoperative physical therapy may be advised. Arrange home support, mobility aids, and transportation, and follow all surgeon instructions to minimize risks and ensure a smoother recovery after the procedure.
What Happens During Proximal Hamstring Reconstruction?
During proximal hamstring reconstruction, the patient is given general or regional anesthesia. The surgeon makes an incision near the buttock crease to access the torn hamstring tendons. Scar tissue is cleared, and the retracted tendons are identified.
If the tendons cannot be repaired directly, a graft (from the patient or donor) is used to reconstruct them. The graft is then secured to the pelvic bone using sutures or anchors.
The incision is closed, and a dressing is applied. The procedure typically takes 2–3 hours, depending on complexity.
What Does Postoperative Care and Recovery Involve with Proximal Hamstring Reconstruction?
After proximal hamstring reconstruction, care includes pain control, wound care, and the use of a brace to limit hip movement. Weight-bearing is restricted initially, often with crutches. Physical therapy begins gradually to restore strength and flexibility. Avoid excessive stretching or sitting for long periods. Regular follow-ups monitor healing, and full recovery may take several months with consistent rehabilitation and activity modification.
What are the Risks and Complications of Proximal Hamstring Reconstruction?
While generally safe, proximal hamstring reconstruction carries some potential risks, such as:
- Infection at the surgical site
- Bleeding or hematoma formation
- Nerve injury, particularly irritation of the sciatic nerve
- Blood clots (deep vein thrombosis)
- Persistent pain or weakness
- Re-tear or graft failure
- Delayed healing or wound complications
