Traumatic Posterolateral Corner Of The Knee

NCT03850262 | Unknown

• Study Type: observational
• Target: 40
• Locations: 0 countries
• Sites: N/A

Brief Summary

The posterolateral corner (PLC) is known as the "dark side of the knee" due to its complex and variable anatomy.Its stability is provided by capsular and non-capsular structures that function as static and dynamic stabilizers. The structures of the PLC are primarily responsible for resisting varus angulation and external tibial rotation. They also act as secondary stabilizers, in conjunction with the cruciate ligaments, to prevent anterior and posterior translation during the early phase of flexion (0°-30°) PLC injures are relatively uncommon, occurring in approximately 16% of all knee injuries. They are rarely seen in isolation, as the majority is associated with concomitant cruciate ligament tears, as well as meniscal tears and injuries to the medial ligamentous structure.

Conditions

Traumatic Posterolateral Corner Of The Knee

Outcome Measures

Primary Outcomes (1)

• Accuracy of MRI in diagnosis of forty patients with posterolateral corner trauma of the knee.

  MRI at Radiological department will be done to evaluate injuries of PLC posterolateral corner of the knee in correlation with clinical or operative findings (either open or arthroscopic) as gold standard.

Radiation: MRI

Interventions

MRI RADIATION

The study will be done on 1.5T MR unit (Siemens) and 1.5T MR unit (Philips) at Assuit University Hospital, or 1.5T MR unit (G.E.) at Eman General Hospital. * The field of view varied between 14 cm and 16 cm, and slice thickness varied between 3 and 4 mm, with 0.5 mm intersection gap. * Imaging sequences included sagittal PD proton density, T2 and STIR, axial PD, coronal STIR and coronal oblique.

Study Population

patients with posterolateral corner trauma of the knee

You may qualify if:

• Patients have positive tests of posterolateral corner instability by clinical examination.
• Patients who suspected by Plain X-ray to have posterolateral corner injury.

You may not qualify if:

• Patients whom previously underwent arthroscopy or surgically intervention to knee joint.
• Patients with history of fracture repaired by metal plates or screws.
• Patients have phobia of indoor places.
• Patients with contraindication to MRI like intra-cerebral aneurysmal clips, cardiac pacemaker, and metallic foreign body at region of examination
