BACKGROUND MRI analysis of subtalar ligaments in the tarsal sinus has not been well performed. We retrospectively investigated the appearance of subtalar ligaments using 3D isotropic MRI and compared imaging findings of subtalar ligaments between patients with subtalar instability (STI) and controls. METHODS Preoperative MRIs of 23 STI patients treated with arthroscopic subtalar reconstructio...

PURPOSE To investigate the patterns of medial meniscus (MM) tears in patients with varus knee osteoarthritis who underwent total knee arthroplasty and analyze the factors that could affect MM tears. MATERIALS AND METHODS The patients (365 knees, 268 patients) were classified into three groups; group I with MM posterior horn (PH) tear only; group II with MM root tear only; and group III with M...

Introduction: The normal ACL consists of the anteromedial (AM) and posterolateral (PL) bundles, each having different functions. Recently, authors reported the first clinical procedure for ‘anatomic’ doublebundle ACL reconstruction, in which they defined this procedure as involving transplantation of the 2 tendon grafts at the center of the anatomic attachment of the AM and PL bundles, respecti...

PURPOSE To establish the sensitivity and specificity of indirect signs at magnetic resonance (MR) imaging of anterior cruciate ligament (ACL) tear. MATERIALS AND METHODS MR images of the knees of 89 consecutive patients (54 with torn and 35 with normal ACLs) were reviewed. RESULTS The indirect signs were as follows (first percentage is sensitivity; the second, specificity): angle between la...

Of 353 arthroscopic peripheral meniscal repairs performed using the "outside to inside" suturing technique with rasp preparation of the tear region, 74 repairs (50 medial and 24 lateral) were assessed by second-look arthroscopy and are the basis of this report. Results were graded as either healed, incompletely healed, or failed; these findings were correlated with clinical symptoms and associa...

background: a rare and devastating complication following anterior cruciate ligament (acl) revision reconstruction is femoral fracture.    case presentation: a 35-year old male soccer player with a history of acl tear from the previous year ago, who underwent arthroscopic acl reconstruction and functioned well until another similar injury caused acl re-rupture. revision of acl reconstruction wa...

This study reports 18 patients with 19 combined ligament injuries with complete anterior cruciate ligament (ACL) tear and a minimum grade II medial collateral ligament (MCL) tear who underwent early reconstruction of the ACL and nonoperative treatment of the MCL. Inclusion criteria included ACL reconstruction performed within 3 weeks of initial injury, no history of antecedent injury to the ips...

There are an estimated 80,000 to 100,000 anterior cruciate ligament (ACL) repairs in the United States each year. Most ACL tears occur from noncontact injuries. Women experience ACL tears up to nine times more often than men. Evaluation of the ACL should be performed immediately after an injury if possible, but is often limited by swelling and pain. When performed properly, a complete knee exam...

Unilateral anterior cruciate ligament (ACL) tear is a common injury seen by sports medicine orthopedic surgeons. However, a bilateral simultaneous ACL injury is extremely rare and has been reported only three times in the literature. We present a young female skier with simultaneous bilateral ACL tears that were managed with staged ACL reconstruction. We then conducted a nationwide survey (Unit...
