Posterolateral instability (PLI) is common with posterior cruciate ligament tears and is less common with anterior cruciate ligament tears, and isolated PLI is rare. There are varying degrees of PLI with respect to pathologic external tibial rotation, and varus laxity. Surgical treatment of PLI must address all components of the PLI (popliteus tendon, popliteofibular ligament, lateral collatera...

BACKGROUND The ideal treatment for patients presenting with bilateral anterior cruciate ligament (ACL) deficiency remains controversial. PURPOSE To evaluate cost and early functional results after bilateral ACL reconstruction at a single setting. STUDY DESIGN Retrospective review. METHODS Eleven patients (22 knees) who underwent bilateral ACL reconstruction at a single setting were compar...

The goal of knee ligament reconstruction is to return the athlete to the previous level of function as quickly and as safely as possible. The appropriate level of aggressiveness in returning the athlete to sport remains controversial. Information in the literature regarding safe return to play has been dominated by the anterior cruciate ligament (ACL) reconstruction literature. The basic concep...

PURPOSE It seems that there is an association between the anterior cruciate ligament (ACL) and stability of the knee. This study aimed to evaluate the balance condition of the injured and non-injured sides of the coper and non-coper ACL-D (deficient) subjects during single and bilateral standing conditions. METHODS This case-control study was carried out on 10 coper and 5 non-coper ACL-D knee...

BACKGROUND The hamstring muscles are well positioned to limit both anterior tibial translation and anterior cruciate ligament strain during the knee flexion phase of a jump landing. We hypothesized that systematically increasing or decreasing hamstring tension during the knee flexion phase of a simulated jump landing would significantly affect peak relative strain in the anterior cruciate ligam...

Meniscal ramp lesions have been reported to be present in 9% to 17% of patients undergoing anterior cruciate ligament reconstruction. Detection at the time of arthroscopy can be accomplished based upon clinical suspicion and careful evaluation without the use of an accessory posteromedial portal. Options for surgical treatment include arthroscopic repair using an all-inside or inside-out techni...

This article describes using of this new, improvised instrument that enables better removal of ACL remnants, increased visibility of the intercondylar notch, precise location of the femoral tunnel and by doing this shortens the operative time. Also, the use of this instrument is cost beneficial, because it decreases the number of disposable shaver tips used and can decrease the cost of the proc...
