Lateral Gutter Knee Anatomy

The lateral gutter drive through sign signified as the ability to advance the arthroscope into the posterolateral compartment between a lax popliteus tendon and the lateral femoral condyle suggests an avulsion of the popliteus off the femur.

Lateral gutter knee anatomy.

With knee flexed to 90 move to medial compartment. The lateral gutter should be visualized and again a similar inspection to the medial gutter should be performed looking for synovitis loose bodies and marginal osteophytes. The patellofemoral joint occurs where the patella and the femur meet behind the kneecap and comprises the third compartment of the knee. 54 7 and a gentle milking maneuver should be performed to assess for the presence of loose bodies that may move back and forth within the popliteal hiatus.

Thus the medial femoral condyle and medial tibial plateau are more elongated or ovoid than in the lateral compartment. Lateral meniscus medically reviewed by the healthline medical network the lateral meniscus is attached to the shin and is located on the outer side of the knee. Anterior horn of lateral meniscus. This study suggests using the sign to guide the placement of incisions and the repair procedure.

For further flexing and exposing of the knee joint the subperiosteal tissue should be dissected along the tibial insertion of the patellar tendon. Located on the outside of the knee joint the posterolateral corner plc of the knee functions to stabilize the knee against direct lateral or external forces. Osseous anatomy if an analogy can be made to the elbow the lateral compartment of the knee is analogous to the radiocapitellar joint whereas the medial compartment is analogous to the olecranon trochlear articulation. Injuries that occur to this area are often due to a sports impact injury from sports like football soccer skiing and basketball.

The popliteal hiatus should be identified in this area fig. With knee fully extended start in suprapatellar pouch. Embryology and anatomy the knee develops from mesodermal elements and is initially separated into three compartments medial lateral and suprapatellar. The membrane separating the compartments is resorbed between the 9thto 12thweek of gestation forming a single joint compartment by the 16thweek.

Once the patella is everted a bent hohmann or a z retractor is introduced along the lateral gutter of the tibial metaphysis to maintain the dislocation of the patella and the extensor mechanism.
