“…These are placed under increasing tension during knee flexion and external tibial rotation [23] and create medial, superior and anterior translation in the posterior horn of the lateral meniscus [27]. Similarly, the popliteus muscle also has attachments to the posterior horn of the lateral meniscus and has been implicated in its translation [16]. Furthermore, disruption of the attachments has been associated with lateral meniscal dysfunction [32].…”

“…1 Functional studies on POP activity in humans have demonstrated that the active role of the muscle is to internally rotate the tibia on the femur. 6,7 In initial flexion, the POP retracts the lateral meniscus 8 and unlocks the knee joint by inward rotation of the tibia. The locking mechanism is provided by the larger medial condyle of the femur, which places the tibia in an externally rotated position in extension.…”

The purpose of this study was to determine whether m. popliteus (POP) activity would contribute to the control of knee joint position in unpredictable and in self-initiated provocations of standing balance. Ten healthy women (age 25.2 AE 4.5 years, means and SD) without known knee pathology were tested for postural reactions (1) to unpredictable support surface translations in anterior and posterior directions, and (2) in self-initiated balance provocations in a reaction time (RT) forward reach-and-grip task. Electromyographic activity was recorded from POP and other leg muscles plus the deltoid muscle. Three-dimensional kinematics were captured for the knee joint and the body centre of mass was calculated. POP was active first of all the muscles recorded, regardless of translation direction, and knee joint movements elicited were either knee extension or external rotation of the tibia. In the RT task, the POP was active after initiation of reaching movement, and there was little consistency in the kinematic response. POP activity was not direction specific in response to support surface translation, but appeared triggered from reactive knee joint movement. The response to the support-surface translation suggests that POP served to control knee joint position rather than posture. In the RT task, we could not deduce whether POP activity was attributed to knee joint control or to postural control. ß

“…There is some controversy regarding the exact role of the popliteus tendon. 9,14,56,57 In a previous report of an injury from the same mechanism as described here, 58 arthrotomy for presumed lateral meniscus tear identified an anomalous attachment of the popliteus tendon to the lateral meniscus with an absent posterior third of the lateral meniscus. In another report, three injuries were described in which each patient had disruption of a fascicular attachment between the popliteus and lateral meniscus, which may cause meniscal instability and locking of the knee.…”

Internal Rotation Knee Injury during Ballroom Dance

Dance injuries associated with internal rotation of the leg are unusual and the injuries observed in ballet, modern, and aerobic dance are often associated with the externally rotated (turned out) or neutral (parallel) positions. This report presents a case of an international-style ballroom dancer who sustained a strain to the popliteus tendon without lateral meniscus tear during execution of the syncopated spin, a dance figure involving internal rotation of the leg. Tansient locking of the knee occurred. Pain was located at the posterolateral knee. Examination showed posterolateral joint line tenderness and pain with active external rotation of the flexed knee. Magnetic resonance imaging (MRI) showed effusion around the popliteus tendon. The patient recovered with activity limitation over several weeks. The case demonstrates that ballroom dance activity may result in an internal rotation injury to the knee, an injury that is uncommon in other dance forms.
