Area of Science:

Orthopedic surgery
Sports medicine
Surgical technique innovation

Background:

Proximal hamstring tendon tears are common athletic injuries.
Surgical repair is increasingly used for these injuries.
Current endoscopic techniques use simple or mattress sutures.

Purpose of the Study:

To evaluate a modified whipstitch technique for endoscopic proximal hamstring tendon repair.
To hypothesize that this technique provides superior suture purchase and tendon fixation compared to traditional methods.

Main Methods:

Endoscopic repair in the prone position using two gluteal crease portals.
Placement of a triple-loaded suture anchor in the ischial tuberosity.
Construction of a modified whipstitch using a tissue penetrator and suture-passing device.

Main Results:

Endoscopic repair shows improved functional outcomes in most patients.
Over 70% of patients achieve an acceptable symptom state post-surgery.
Return-to-sport rates range from 77.3% to 95% in reported literature.

Conclusions:

A modified whipstitch offers a potentially more durable endoscopic hamstring tendon repair.
This technique may combine the benefits of open repair with reduced endoscopic surgery complications.
Further research comparing suture techniques and outcomes is warranted.
