BACKGROUND During the early postoperative period, the fixation of a hamstring graft to the bone tunnel is the primary factor in limiting rehabilitation. HYPOTHESIS The initial fixation strength of a double cross pin fixation technique is comparable with the biodegradable interference screw fixation technique. STUDY DESIGN Experimental laboratory study. METHODS The authors examined the ini...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013009426 DESCRIPTION A 9-year-old girl sustained an injury to her right knee during sliding on the playground. Immediately after the injury, she felt a sharp pain in her knee and she was unable to walk. On physical examination there was marked knee effusion without ecchym...

OBJECTIVE To determine the initial resistance of fixation using the Rigid Fix(®) system, and compare it with traditional fixation methods using metal interference screws; and to evaluate the resistance of the fixation with the rigid fix system when the rotational position of the bone block is altered in the interior of the femoral tunnel. METHODS forty ovine knee specimens (stifle joints) wer...

OBJECTIVES We performed in vitro validation of a non-invasive skin-mounted system that could allow quantification of anteroposterior (AP) laxity in the outpatient setting. METHODS A total of 12 cadaveric lower limbs were tested with a commercial image-free navigation system using trackers secured by bone screws. We then tested a non-invasive fabric-strap system. The lower limb was secured at ...

Historically, arthroscopic anterior cruciate ligament (ACL) reconstruction has a low rate of infection, with a reported prevalence of 0.14% to 5.7%. While uncommon, these infections generally occur early and are characterized by either cellulitis at the graft insertion site and/or septic arthritis. Subacute infections are less well characterized. Although bioabsorbable interference screws have ...

the present review classifies and describes the multifactorial causes of anterior cruciate ligament (acl) surgery failure, concentrating on preventing and resolving such situations. the article particularly focuses on those causes that require acl revision due to recurrent instability, without neglecting those that affect function or produce persistent pain. although primary acl reconstruction ...

the anterior cruciate ligament (acl) is composed of two bundles, which work together to provide both antero-posterior and rotatory stability of the knee. understanding the anatomy and function of the acl plays a key role in management of patients with acl injury. anatomic acl reconstruction aims to restore the function of the native acl. femoral and tibial tunnels should be placed in their anat...

Objectives: The aim of this study was to evaluate the necessity staple use and importance screw diameter in anterior cruciate ligament (ACL) reconstruction. Methods: Twenty-eight sheep hind legs were divided into four groups terms tibial side fixation type as 7 mm bioabsorbable (Group 1), 2), 8 3), 4). maximum force causing insufficiency graft, strength between recorded. results compared among ...
