PURPOSE: Repairs of the posterior horn of the lateral meniscus can be technically challenging. In contrast to medial meniscus repairs, the capsule around the posterior segment attachment of the lateral meniscus is quite thin. This study evaluates the clinical results of an arthroscopic all-inside repair technique for unstable, vertical, lateral meniscus tears, using a suture repair placed directly into the popliteus tendon. METHODS: A retrospective analysis of prospectively collected data from the SANTI database was performed...

The cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. The lesion forms at the anterior cruciate ligament insertion creating a painful extension block between femoral intercondylar notch and tibial plateau. We present 2 cases (3 knees) in which cyclops lesions appeared atypically following bicruciate-retaining total knee replacement. Two lesions occurred in a single patient following bilateral knee replacement. One lesion occurred in an active sportswoman...

BACKGROUND AND PURPOSE: Loss of knee range of motion (ROM) has been reported as the most common complication following anterior cruciate ligament reconstruction (ACLR). Arthrofibrosis of the knee, or specifically Cyclops syndrome, has been described as the formation of a scar tissue nodule adjacent to the tibial tunnel of the anterior cruciate ligament (ACL) graft. This lesion often results in loss of knee extension ROM, pain, and impaired function. CASE DESCRIPTIONS: Three consecutive patients were referred to physical therapy following arthroscopic knee surgery for lysis of adhesions of a Cyclops lesion from a previous ACLR...

BACKGROUND: Cyclops syndrome is characterized by loss of terminal knee extension due to proliferative fibrous nodule formation in the intercondylar notch. This complication occurs in the early postoperative period after anterior cruciate ligament reconstruction (ACLR). The pathogenesis of Cyclops syndrome is not well understood. HYPOTHESIS: Persistent hamstring contracture after ACLR is associated with an increased risk of subsequent Cyclops syndrome. STUDY DESIGN: Case-control study; Level of evidence, 3...

In this exploratory study, gait analysis and quantitative MRI (QMRI) were used to assess biomechanical differences in patients that present with cyclops lesions at 12 months after ACL-reconstruction (ACLR). Thirty ACLR patients without and 10 ACLR patients with cyclops lesions underwent 3T MR T1ρ mapping of the reconstructed knee joint prior to ACLR and at 12 months after ACLR, as well as a gait assessment during a fixed walking speed at 12 months after ACLR. Both external sagittal and frontal plane knee joint moments and joint moment impulses were calculated and assessed throughout the stance phase of gait...

OBJECTIVES: To assess the impact of cyclops lesions with MRI in patients treated for anterior cruciate ligament (ACL) tears on clinical outcome. METHODS: In 113 patients (age 29.8 ± 10.5y; 55 females; BMI 24.8 ± 3.7 kg/m2 ) with complete ACL tear, 3 T-MRI scans were obtained before, 6-months, 1-year (n = 75) and 2-years (n = 33) after ACL reconstruction. Presence and volume of cyclops lesions were assessed. Clinical outcomes were measured using the Knee injury and Osteoarthritis Outcome Score (KOOS) and differences between time points (∆KOOS) were calculated...

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...
