Introduction: Spontaneous quadriceps tendon rupture (SQTR) is a rare injury to the knee extensor mechanism that is usually associated with systemic diseases such as end stage renal diseases (ESRD) and it is more prevalent in the elderly. Due to the underlying pathology, quadriceps tendon rupture warrants special considerations and management in its repair.
Case Report: We present two cases of quadriceps tendon rupture in end-stage renal disease (ESRD) patients. The first case; a 57 years old female who had bilateral SQTR and is undergoing hemodialysis. The second patient, a 26 years old male had unilateral quadriceps tendon rupture caused by minimal trauma. The first patient had a trans-osseous repair by direct suturing the quadriceps tendon stump to the proximal pole patella. The second patient was repaired with a modified Bunnel suture and anchor placement on the proximal pole patella. The first case had a re-rupture of the right quadriceps tendon and the second case has recovered with improved outcomes.
Discussion: Spontaneous quadriceps tendon rupture is usually underlined by degenerative changes of the tendons. Special care is needed to address the pathologic tendon underlying SQTR. The current surgical literature still lacks the statistical data that shows which surgical approach is most optimal for SQTR in ESRD patients.
Conclusion: SQTR rupture is generally an injury of brittle tendons caused by underlying diseases. A multidisciplinary and comprehensive approach including a proper surgical approach and postoperative managements are crucial for good functional outcomes of the extensor mechanism.

Purpose: To biomechanically evaluate a flat posterior cruciate ligament (PCL) reconstruction utilizing rectangular femoral bone tunnels.
Methods: Eight fresh-frozen human knee specimens were tested in a six-degrees-of-freedom robotic test setup. In each testing step, a force-controlled test protocol was performed, including 89 N posterior tibial translation (PTT) in neutral, internal and external rotation, from 0 to 90° of flexion.

Background: Although chronic quadriceps tendon rupture and defect are rare, they pose significant challenges in surgical treatment. In these cases, quadriceps tendon reconstruction is necessary. Either autologous or allogeneic tendons have been used for this reconstruction.

Lateral patellar dislocations represent a common orthopaedic condition in young, active individuals who experience patellar instability. Despite increasing interest in re-creating the natural biomechanics and native knee anatomy when performing medial patellar soft-tissue reconstructive procedures, there is no consensus among surgeons regarding the best techniques to use when reconstructing the medial patellofemoral ligament and medial quadriceps tendon-femoral ligament. This article details a method to reconstruct the medial patellofemoral ligament and medial quadriceps tendon-femoral ligament using a single graft and a single all-suture knotless anchor on the patella.

To compare the clinical outcomes of anterior cruciate ligament (ACL) reconstruction using autografts with and without internal brace augmentation. Data from patients who underwent ACL reconstruction with hamstring and quadriceps tendon autografts, with a minimum follow-up of one year, with or without internal brace augmentation were collected prospectively analyzed retrospectively. The Lysholm and Tegner functional scores were collected before and after surgery, as well as data on postoperative complications.
