INTRODUCTION Reconstructing a torn anterior cruciate ligament (ACL) in a knee that has had prior ACL surgery presents challenges, especially if multiple procedures have been done in the past. Revision ACL surgery will continue to become more common as the number of primary ACL reconstruction procedures continues to increase. A common problem faced by the surgeon in the revision setting is an en...

An isometer, a highly compliant spring-scale device for measuring suture displacement, has been used intraoperatively by surgeons to select the optimal placement of the femoral tunnel for an anterior cruciate ligament graft. The isometer measures the displacement of a suture centered in a tibial tunnel and attached to an intraarticular location on the femur before the femoral tunnel is drilled....

The tarsal tunnel syndrome consists of a complex of symptoms affecting the foot and is thought to be due to a compression neuropathy of the posterior tibial nerve within the fibro-osseous “ tunnel “ that lies beneath the flexor retinaculum on the medial side of the ankle. No comprehensive description of this condition can be found until 1962, when two isolated cases were reported (Keck 1962, La...

Background The residual laxity after transtibial posterior cruciate ligament (PCL) reconstruction has been reported by several authors. The sharp angle where the graft exits the tibial tunnel, which is known as "killer turn", is believed to be the main reason. The purpose of this study was to reveal the mechanism of "killer turn" and its effect on both graft and tunnel inlet. Methods A total ...

BACKGROUND Regarding reconstruction surgery of the anterior cruciate ligament (ACL), there is still a debate whether to perform a single bundle (SB) or double bundle (DB) reconstruction. The purpose of this study was to analyze and compare the volume and surface area of femoral and tibial tunnels during transtibial SB versus transportal DB ACL reconstruction. METHODS A consecutive series of 2...

OBJECTIVES To evaluate and compare bone tunnel positioning in anterior cruciate ligament (ACL) reconstruction surgery using the arthroscopic technique and the open technique consisting of arthrotomy. METHOD A comparative retrospective study on 70 patients with ACL lesions was conducted. Thirty-five patients underwent ACL reconstruction by means of the open technique and 35 by means of the art...

Many complications have been reported during or after anterior cruciate ligament (ACL) reconstruction, including infection, bleeding, tibial tunnel widening, arthrofibrosis, and graft failure. However, arterial injury has been rarely reported. This paper reports a case of an anterior tibial arterial injury during bicortical tibial drilling in arthroscopic ACL reconstruction, associated with an ...

Tarsal tunnel syndrome characterises a complex of symptoms that result from compression of the posterior tibial nerve as it passes through the fibro-osseus tunnel located beneath the flexor retinaculum on the medial aspect of the ankle.' The syndrome has been described in several case reports and review articles24 since Keck's5 and Lam's6 original case reports in 1962. Whereas other nerve entra...

Tarsal tunnel surgery complicated with ganglia or any other type of cystic mass can be a very challenging operation. Preoperative planning before any tarsal tunnel surgery involving a soft-tissue mass is imperative. Plans to reconstruct the posterior tibial nerve and/or artery should be in place. The authors will present a case study that involved tarsal tunnel syndrome with an associated gangl...

Tarsal tunnel intracompartment pressures were determined in 10 fresh-frozen normal human adult cadaver specimens. With the foot and ankle held in mild plantarflexion and neutral eversion-inversion, mean tarsal tunnel pressure was minimal (2 +/- 1 mmHg). However, when the foot and ankle were positioned in full eversion, mean tarsal tunnel pressure increased to 32 +/- 5 mmHg (P < or = 0.005); in ...
