Hamstring Injuries & Proximal Tendon Repair
Comprehensive Diagnostic Evaluation, Non-Operative Rehabilitation Protocols, and Advanced Operative Proximal Hamstring Tendon Repair under Consultant Orthopaedic Surgeon Mr Lebur Rohman
1. Overview of Hamstring Injuries
The hamstring complex consists of three main muscles at the back of the thigh (biceps femoris, semitendinosus, and semimembranosus) that originate at the ischial tuberosity (sit-bone) of the pelvis and extend past the back of the knee joint. Hamstring injuries are among the most frequent athletic soft-tissue injuries, ranging from acute muscle belly strains during high-speed sprinting to full-thickness proximal tendon avulsions caused by forced hip hyper-flexion with an extended knee (such as slipping accidents or sports injuries).
⚡ Muscle Strain (Grade I–III)
Occurs within the muscle belly or myotendinous junction. Symptoms include sudden sharp posterior thigh pain, localized swelling, bruising, and tenderness, typically managed with structured physiotherapy.
💥 Proximal Tendon Avulsion
The main hamstring tendons pull away or detach completely from the ischial tuberosity (sit-bone). Causes severe deep buttock pain, marked leg weakness, persistent fatigue, and sitting discomfort.
🔍 Diagnostic MRI Assessment
An urgent high-definition MRI scan is vital to differentiate between a muscle belly strain, a partial tear, or a complete 3-tendon retracted avulsion to guide appropriate treatment selection.
2. Non-Operative Rehabilitation for Hamstring Strains
Most mild-to-moderate hamstring muscle belly strains (Grades I and II) respond exceptionally well to a structured, progressive rehabilitation protocol focusing on eccentric strength training, progressive lengthening, dynamic core stability, and gradual return-to-running drills.

3. How Proximal Hamstring Tendon Repair is Performed
When a complete rupture or multi-tendon proximal avulsion occurs at the sit-bone, non-operative management often leads to persistent leg weakness, sitting discomfort, and sciatica-like nerve irritation. In active individuals, surgical repair is performed to reattach the retracted tendons securely back to bone.
Surgical Repair Technique
The procedure is performed under general anaesthesia with the patient lying in a prone position. Mr Lebur Rohman utilizes a meticulous anatomical repair approach:
- Exposure & Protection: A small transverse incision is made in the crease below the buttock. The sciatic nerve is carefully identified, decompressed, and protected throughout the operation.
- Bone Footprint Preparation: The retracted tendon ends are mobilized, and the anatomical attachment site on the ischial tuberosity (sit-bone) is cleaned to fresh, healthy bone.
- Suture Anchor Insertion: Specialized bone anchors (typically 2 to 4 bio-compatible suture anchors) pre-loaded with high-strength orthopedic tape are implanted into the sit-bone.
- Anatomical Tendon Reattachment: The high-strength suture tapes are woven through the hamstring tendons, pulling them flush back onto the bone footprint to facilitate solid bone-to-tendon healing.

Following proximal hamstring tendon repair surgery, a structured protective rehabilitation program is essential to safeguard the tendon reattachment while restoring mobility and strength:
- Weeks 0 – 6 (Protection Phase): Crutch-assisted weight-bearing in a protective hip brace preventing excessive hip flexion/knee extension strain on the repaired tendon.
- Weeks 6 – 12 (Mobility & Active Recovery): Gradual weaning from brace and crutches; gentle hip range-of-motion exercises, stationary cycling, and gait retraining.
- Months 3 – 6 (Strength & Dynamic Progressions): Progressive eccentric strengthening, hamstring curl exercises, and light jogging progressions.
- Months 6+: High-speed sprinting drills, agility training, and full return to competitive sports and demanding physical work.

According to Consultant Orthopaedic Sports Surgeon Mr Lebur Rohman, a mid-thigh hamstring muscle strain usually presents as localized cramping or tightness following high-speed running, where walking remains possible despite discomfort.
In contrast, a proximal hamstring tendon avulsion involves the complete tear or detachment of the main tendons from the ischial tuberosity (sit-bone). It is typically caused by forced hip hyper-flexion with an extended knee (e.g. water-skiing, sports tackles, or slipping). Symptoms include a distinct popping sensation, deep buttock pain, severe bruising down the posterior thigh, difficulty bending the knee against resistance, and significant pain when sitting. An urgent MRI scan is required for definitive diagnosis.
Standard X-rays only assess bone structures and cannot visualize soft-tissue tendon ruptures. A specialized posterior hip/thigh MRI scan is critical for Mr Lebur Rohman to evaluate:
- Anatomical location of the injury (muscle belly, myotendinous junction, or bone-tendon origin).
- Number of tendons involved (partial tear vs complete 3-tendon avulsion).
- Tendon retraction distance away from the pelvic sit-bone footprint (retraction over 2cm strongly indicates surgical anchor reattachment).
Acute proximal hamstring tendon repair performed by Mr Lebur Rohman within 2 to 4 weeks yields superior functional outcomes, reduced nerve complication risks, and faster return to sport. Delaying surgery allows the torn tendons to retract further down the thigh, form dense scar tissue, and create painful adhesions around the adjacent sciatic nerve—making delayed chronic repairs technically complex.
To protect the newly reattached suture anchors into the sit-bone, patients undergo a protected recovery phase for approximately 6 weeks. This includes wearing a customized range-of-motion hip brace and using crutches to prevent excessive hip flexion or sudden stretch on the healing tendon footprint.
Under Mr Lebur Rohman's structured rehabilitation plan, average recovery milestones include:
- Sedentary / Desk Work: 2 to 3 weeks (with ergonomic sitting support).
- Driving: 6 to 8 weeks (once off crutches and full emergency stop muscle strength is confirmed).
- Light Running & Jogging: 3 to 4 months post-op.
- High-Speed Sprinting & Contact Sports: 6 months following objective strength and agility discharge testing.
Yes. Chronic proximal hamstring avulsions (injuries older than 6 weeks) can be successfully treated by Mr Lebur Rohman. Chronic reconstruction requires specialized sciatic nerve neurolysis (freeing the nerve from scar tissue) and tendon mobilization to achieve secure suture anchor fixation back to the ischial tuberosity.
