popliteus tendon tear

Download scientific diagram Partial-thickness tear of the popliteus tendon. Injuries of the popliteus are often associated with.

Posterior Cruciate Ligament Injury

In addition the knee can.

. Injuries of the popliteus can be classified as first- second- or third-degree strains. Popliteus pop-lih-t-us tenosynovitis ten-o-sin-o-vi-tis is a tear in the popliteus tendon. A little bit of femur bone is pulled off with the tendon although the tendon itself is not.

The popliteus tendon goes from the bottom back of the thighbone across the back of the knee to the top front of the shinbone. The Popliteus Tendinitis typically manifests as point tenderness in the lateral aspect of the knee corresponding to the popliteus insertion site which is exacerbated with eccentric loading. National Center for Biotechnology Information.

Partial tears may be treated conservatively whereas complete tears retracted beyond the popliteal hiatus require an open or combined approach. Palpation of the popliteus tendon is easiest when the foot of the involved leg is placed on the uninvolved knee in the. In chronic conditions swelling may be noted along the lateral joint line.

Popliteus damage leading to significant incompetence of this structure is generally in the form of an avulsion a tearing off in the region where the tendon attaches to the femur. The lower prevalence may also relate to the longer duration allowed between time of injury and surgery. It forms the floor of the popliteus fossa.

The femoral insertion has a crescent shape with the superior aspect being concave 10. Actual tears of the substance of the popliteus are less common but do happen and bleeding may occur into the joint. Popliteus injuries or injuries of the popliteus musculotendinous complex occur within the scope of posterolateral corner injuries of the knee and include avulsions complete and partial tendinous and myotendinous tears as well as muscle injuries.

The Popliteus Muscle tendinous unit is unique in that the distal muscular attachment is designated the insertion and the tendinous proximal femoral attachment is designated the origin. Generally people can damage their popliteus tendon after a knee twist or overuse. Also the tendon can be injured after a total knee replacement.

Sometimes movement of the knee can cause a popping sensation. The popliteus muscle arises from the proximal posterior surface of the tibia and has insertions into the posterior portion of the lateral meniscus and the femur both deep and anterior to the lateral collateral ligament. The tendon of the.

This difference likely relates to the lower prevalence of injury in their study with only 8 of their patients having a biceps tendon tear and 11 with popliteus tendon tear compared to 44 and 64 respectively in the current study. A tendon is a cord of tough tissue that connects muscles to bones. Dysfunction of the popliteus is often underappreciated and is usually secondary to direct or indirect trauma.

Usually people with popliteus tendinopathy feel pain at the back or outside of the knee during walking stairs and running. Popliteus tendon tenosynovitis Abstract This series of case suggests that the entity of tenosynovitis of the popliteus tendon is more common than once recognized. The described surgical technique is a reproducible and consistent approach for popliteal tendon repair based on the anatomy and principles of the posterolateral corner.

The presence of an avulsed. The muscle inserts into a triangular area along the posteromedial aspect of the proximal tibial metaphysic above the soleal line. MRI demonstrated an ACL injury medial meniscal tear bone bruising and impaction at the lateral femoral condyle and tibial plateau and a tear of the posterior horn of the lateral meniscus that was displaced behind the popliteus.

In the ER the patient complained of medial knee pain and had a significant joint effusion. The advantages of surgical intervention in an isolated popliteal tendon tear are that it restores the anatomy thereby protecting the surrounding structures from future injury. A high index of sucpicion and accurate palpation of the lateral aspect of the knee lead one to the diagnosis.

It is also called popliteus tendinitis. Tears of the popliteus tendon should be characterized as partial or complete intra-articular or extra-articular and with regards to the proximity to the popliteal sulcus and the extent of retraction. Sagittal T2-weighted image shows a partial-thickness tear of the popliteus tendon black arrow at.
