The anteroposterior stability of involved and normal knee in three groups were examined in 3, 6, and 12 months post-operatively, including the Anterior drawer test
, Lachman test, and the stress radiography.
Lachman test: This test is performed in the same way as the anterior drawer test
, but with the knee flexed to 20 degrees.
Orthopedic testing such as positive Lachman's and anterior Drawer test
, indicating ACL instability, (3) along with appropriate imaging confirm the diagnosis and success of reduction.
The Anterior Drawer Test
(Gerber and Ganz, 1984) at 80[degrees] abduction was hypermobile and pain free; at 100[degrees] abduction it was hypermobile and produced pain and apprehension.
The anterior drawer test
is of unproven benefit in diagnosing rupture of the anterior cruciate ligament (ACL).
Similar to an anterior drawer test
, the Lachman test is performed with the patient supine and the knees flexed 20 degrees (instead of 90 degrees as with the anterior drawer test
Baseline measurements included foot posture assessment (using FPI-6), foot characteristics (length, width and length to width ratio), generalized joint laxity (using Beighton and Horan score), lateral ankle ligaments laxity (measured by anterior drawer test
and talar tilt test), static and semidynamic balance (measured by single-leg balance test and star excursion balance test), and goniometric measurement of ankle plantarflexion, ankle dorsiflexion and first metatarsophalangeal dorsiflexion.
Outcome was measured using Lysholm knee score, IKDC Score, Anterior drawer test
, Range of motion of the knee joint and Quadriceps power of ipsilateral knee.
