Cyclops lesion was previously described as a fibrous lesion with a granulation tissue core originating from the tibial insertion of the anterior cruciate ligament (ACL) graft. 1 Recently, two case reports described inverted cyclops le - sions, which originated from the femoral aspect of the ACL. 2,3 Both cyclops and inverted cyclops lesions are usually associated with a block to knee extension. Here we present a case of an 18-year-old female who developed a painful inverted cyclops lesion originating from the femoral notch above hamstring autograft without restriction to knee range of motion 20 months after arthroscopically assisted ACL reconstruction...

BACKGROUND: One of the well-studied epidemiological phenomena of anterior cruciate ligament (ACL) injuries is the 2- to 9-fold increase in the relative risk of ACL rupture in female athletes compared with male athletes. However, the influence of patient sex on the outcome after ACL reconstruction remains unclear, with some authors reporting inferior outcomes in females and others noting no significant difference. PURPOSE: To provide a comprehensive systematic review and meta-analysis to examine the possible association between patient sex and the subjective and objective outcomes after ACL reconstruction...

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using autografts or allografts is a common surgical procedure, particularly in young athletes. Although the procedure has excellent success rates, complications such as mechanical impingement, graft rupture, and arthrofibrosis can occur, often necessitating additional surgery. Magnetic resonance (MR) imaging has become a valuable tool in evaluating complications after ACL reconstruction. We report two cases of ACL reconstruction complicated by arthroscopically proven partial graft tears...

Cyclops are among the best-known monsters of Greek mythology, also mentioned in art and literature. According to the most recent scientific knowledge, the malformations caused by defective development of the anterior brain and midline mesodermal structures include cyclopia (synophthalmos), ethmocephaly, cebocephaly and arrhinencephaly. These severe forebrain lesions often are accompanied by severe systemic malformations, and affected infants rarely survive. Neither true cyclopia nor synophthalmos are compatible with life because an anomalous development of the brain is involved...

PURPOSE: The purpose of this study was to investigate the incidence of cyclops lesions and its relationship with the cross-sectional area of the intercondylar notch. METHODS: For this study, 55 patients (24 male and 31 female) underwent follow-up arthroscopy after bi-socket anterior cruciate ligament reconstruction with hamstring tendon grafts were included. All patients underwent magnetic resonance imaging measurements of intercondylar notch dimensions. We compared the femoral intercondylar notch sizes and bone tunnel sizes between knees with cyclops lesions (cyclops group) and those without cyclops lesions (no-cyclops group)...

There have been a few reports of cyclops syndrome following a partial rupture of the anterior cruciate ligament (ACL) without surgical reconstruction. We have reported for the first time a case of cyclops lesion with locking symptoms after partial rupture of the ACL. A 14-year-old girl twisted her right knee when landing after a jump while playing basketball, and locking symptoms of the knee appeared. Cyclops syndrome occurred because of a partial rupture of the posterolateral bundle of the ACL was diagnosed and removed as a lump by punch...

BACKGROUND: The different functions of the two anterior cruciate ligament (ACL) bundles have increased interest in tears of only one of these two bundles. The purpose of this study was to assess the outcome of selective reconstruction of an injured bundle of isolated anteromedial bundle (AMB) or posterolateral bundle (PLB) tears. METHODS: Consecutive series of 147 ACL reconstructions was prospectively analyzed. Patients with partial ACL tears who underwent selective bundle reconstructions were studied...

PURPOSE: 'Clinical cyclops syndrome' is associated with pain and a palpable 'clunk' at terminal extension with the loss of full extension. The aims of this prospective controlled study were: (1) to assess whether the minimal debridement of the ACL stump and notch is associated with an increased incidence of clinical cyclops lesions, (2) to look at the incidence and natural history of 'MRI cyclops' lesions using serial MRI's and (3) to assess whether 'MRI cyclops' lesions are associated with the loss of extension...

Anterior cruciate ligament (ACL) injury was very common, and its reconstruction is one of the most commonly performed orthopaedic surgeries. A standard treatment option for ACL complete rupture in active young patients is debridement of remnant tissue and reconstruction with various types of tendon graft. However, "A tibial peel off tear" of ACL without bony avulsion can be treated using preservation of original ACL and trans-osseous pullout suture repair. The IKDC subjective score was 90, the objective score was A, and the Lysholm score was 95 at 24 months after surgery...

Development of a cyclops lesion is a well described complication after anterior cruciate ligament (ACL) reconstruction. It commonly results in gradual extension loss during the early postoperative course, and magnetic resonance imaging (MRI) of the soft tissue nodule attached to the ACL graft is needed. Cyclops lesions are easy to diagnose based on the symptoms and MRI findings. Previous study showed that 78.6% of cyclops lesions had extension loss within 6 weeks postoperatively, and the diagnosis of 92.8% cases of cyclops lesions was established within 6 months...

INTRODUCTION: Anterior cruciate ligament (ACL) rupture is the most common surgically treated ligament injury. Many efforts have been taken to reconstruct it as anatomically as possible to restore knee stability and, possibly, prevent knee osteoarthritis. SOURCES OF DATA: A literature search was performed using the isolated or combined keywords 'ACL augmentation remnant', 'ACL reconstruction and remnant and stump', 'ACL reconstruction and remnant and stump preserving and stability' and 'ACL remnant complete tear' with no limit regarding the year of publication...
