A cannula can comprise a main body portion having an outer peripheral surface, a longitudinal axis, a transverse axis that is perpendicular to the longitudinal axis, and opposing first and second ends that are spaced relative to the longitudinal axis. A through-bore can extend through the main body portion. The through bore can comprise a first guide bore, a second guide bore spaced from the first guide bore relative to the transverse axis, and a connecting portion that extends between the first bore and the second bore. A tip portion can extend from the second end of the main body portion relative to the longitudinal axis. The tip portion can comprise a bore therethrough that is coaxial with the first guide bore.

An unmet need of orthopedic practitioners is a clinically-relevant measurement device and technique to objectively quantify joint (e.g., knee) stability, including rotational stability. An apparatus and method is disclosed for performing a mechanical joint movement test, such as a knee pivot shift test, through the application of standardized dynamic loads (e.g., using a constant-tension spring or other mechanism). When used for knee evaluation, this test reliably induces the characteristic 'pivot' tibial subluxation/reduction event in an ACL-deficient knee, allowing for more sensitive detection of deficiencies in rotational knee stability, quantification of the relative importance of knee stabilizers, and comparison of the performance of contemporary ACL reconstruction techniques. The test allows for better understanding joint biomechanics and for defining unique kinematic and kinetic signatures for common joint injuries, such as knee injuries, that will be valuable for diagnostic purposes.
