Background: There are several reports on anatomical differences of the meniscus. However, there are only a few reports on abnormalities in both menisci and anatomical differences in anterior cruciate ligament insertions.
Case Presentation: This is a case report of a 36-year-old Hispanic man presenting symptoms, including knee pain, locking, and effusion, with an anatomical abnormality of the menisci corresponding to the fusion of the posterior horns of the menisci in tandem with the insertion of the posterior meniscus fibers in the anterior cruciate ligament.
Conclusions: This is the first study describing a meniscus anatomical variant with isolated posterior junction of the posterior horn with an anomalous insertion to the anterior cruciate ligament. The recognition of meniscus variants is important as they can be misinterpreted for more significant pathology on magnetic resonance images.

Purpose: This study aimed to assess the posterior cruciate ligament (PCL) angle in anterior cruciate ligament (ACL) deficient knees and correlate it with anatomical and demographic factors such as tibial slope, anterior tibial translation, age, gender, and time of injury.
Material And Methods: Patients were eligible for inclusion if they were clinically diagnosed with an ACL tear confirmed by MRI. For each patient, the following parameters were evaluated: PCL angle (PCLA), medial tibial slope (MTS), lateral tibial slope (LTS), medial anterior tibial translation (MATT), and lateral anterior tibial translation (LATT).

Ganglion cysts are commonly found in areas of constant mechanical stress such as the joints and tendons of the wrist or hand as well as the anterior aspect of the ankle. In the knee, parameniscal cysts are often encountered secondary to meniscal tears or articular degeneration. Intra-articular ganglion cysts are uncommon and often arise from the cruciate ligaments and are found in the intercondylar notch.

Knee osteoarthritis (OA) is a common and debilitating disorder marked by joint degradation, inflammation, and persistent pain. This study examined the possible therapeutic effects of curcumin and vitamin D on OA progression and pain in a rat knee OA model by anterior cruciate ligament transection and meniscectomy (ACLT + MMx). Male Wistar rats were categorized into five groups: control, curcumin-treated (100 mg/kg/day), vitamin D-treated (25 µg/kg/day), a combination of vitamin D and curcumin, and sham-operated.

: Postoperative infection following anterior cruciate ligament reconstruction (ACLR) is a rare yet severe complication that can compromise patient outcomes, leading to prolonged recovery, graft failure, and knee dysfunction. Although infection rates are reported to be less than 2%, it remains essential to implement strategies to reduce infection risk and improve surgical outcomes. : This review explores current evidence on the prevention of infections in ACLR, emphasizing the importance of timely antibiotic prophylaxis and vancomycin presoaking of grafts, which has been associated with a substantial reduction in infection rates.

: Up to 27% of anterior cruciate ligament (ACL) reconstruction cases result in a residual positive pivot shift sign, indicating anteroposterior and rotational instability. This instability can compromise returning to sports and increase the risk of further injuries. The biomechanical role of the anterolateral ligament (ALL) in controlling internal knee rotation is well known.
