“…LaPrade et al [21, 26] recommended a field of view that included the fibular head and styloid on all projections and demonstrated that MRI was accurate in depicting the integrity of the individual components of PLC in 20 patients with high‐grade PLRI. A problem with MRI, however, is that it has low credibility in chronic injury cases [12, 39].…”

Diagnosing posterolateral rotatory instability (PLRI) is difficult because it occurs rarely, takes time to manifest, and no single definitive tool exists in diagnosing posterolateral corner injuries. We sought to evaluate the correlation between rotational degrees in the dial test and physical and arthroscopic findings that surgically verified PLRI in the knee joint. Patients (n = 67) who were diagnosed as having PLRI and received posterolateral reconstruction (n = 57) and repair (n = 10) from 1998 to 2006 were recruited. Preoperative physical findings were evaluated under anesthesia, and arthroscopic findings during surgeries were analyzed. A dial test with post-anesthesia (spinal or general) was conducted. We divided patients into three subgroups (A: <15 degrees, B: 15-20 degrees, and C: >20 degrees), according to differences in rotational degrees in the dial test. All tests showed significant differences among the three groups and positive findings increased as the rotational degrees increased. No test showed a statistically significant difference in the specific group. All tests except for popliteal hiatus widening showed significant differences among the three groups and positive findings also increased as the rotational degrees increased. The total incidence and positive rate of each physical examination and the popliteal hiatus arthroscopic findings in PLRI significantly increased as the rotational degree in the dial test increased. The number of positive findings on physical examination was larger than the number of positive findings by arthroscopy in all three groups.

Tendinous insertion of semimembranosus muscle into the lateral meniscus

et al. 1997

Forty-two cadaver knees were used for morphologic and MRI observations of the tendinous distal expansions of the semimembranosus m. and the posterior capsular structures of the knee. A tendinous branch of the semimembranosus m. inserting into the posterior horn of the lateral meniscus was found in 43.2% of the knees dissected, besides five already known insertional branches; capsular, direct, anterior and inferior, as well as the oblique popliteal ligament. The tendon had three morphologic types; thin, broad and round. All three types moved the lateral meniscus posteriorly when pulled on. Thus, the semimembranosus m. may also have a protective function for the lateral meniscus as well as the already well established function of protecting the medial meniscus in knee flexion. When a semimembranosus tendon attachment to the posterior horn of the lateral meniscus is present, its normal insertion is difficult to differentiate from a lateral meniscus tear in MRI and this may cause misdiagnosis.
