Pathological Rupture of the Quadriceps Tendon in a Patient With Osteogenesis Imperfecta With Leg-length Discrepancy:...

Area of Science:

• Orthopedics
• Genetics
• Rheumatology

Background:

• Quadriceps tendon ruptures typically result from severe trauma.
• Pathological ruptures, accounting for one-third of cases, can occur spontaneously or with minor trauma due to underlying systemic diseases.
• Osteogenesis imperfecta (OI) is a rare genetic disorder characterized by defective type 1 collagen, leading to bone fragility, ligamentous laxity, and tendon ruptures.

Purpose of the Study:

• To report a case of pathological quadriceps tendon rupture in a patient with osteogenesis imperfecta.
• To describe the management and outcome of surgical repair in this specific patient population.

Main Methods:

• Case report of a 55-year-old male diagnosed with osteogenesis imperfecta.
• Surgical repair of the right quadriceps tendon rupture utilizing the Krackow suture technique.
• Assessment of postoperative range of motion and pain.

Main Results:

• The patient, diagnosed with OI and presenting with a pathological quadriceps tendon rupture, underwent successful surgical repair.
• Postoperatively, the patient regained preinjury range of motion within 3 months.
• The patient was able to walk without pain following the procedure.

Conclusions:

• Osteogenesis imperfecta is a rare but significant risk factor for pathological quadriceps tendon ruptures.
• Surgical intervention, such as the Krackow suture technique, can lead to favorable outcomes in OI patients with quadriceps tendon ruptures.
• Early rehabilitation and surgical management are crucial for restoring function in these patients.
