Background: Anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries are on the increase in Nigeria and there is no comprehensive study on the relationship between cruciate ligament thickness with age and gender using Magnetic Resonance Imaging (MRI) among Nigerians. Aim of study: The study aimed to assess the thicknesses of the cruciate ligaments among apparently healthy Nigerian population using MRI. Methods: A total of Ninety-four (94) volunteers aged 21 - 70 years who were referred for MRI knee assessment without any ACL and PCL injuries after radiological assessment of their MRI images by a consultant radiologist were recruited for the study. The study was carried out between June 2018 and December 2018. The Age and gender of the volunteers were recorded and the procedure was thoroughly explained to the participants. After removing all non - MRI compliant metallic objects from their bodies, the volunteers lied supine on the couch, arms by the sides, with head first and the knees were positioned on the knee coils and immobilized with cushions.The standard knee MRI examination protocol was adopted for the examinations using a 0.2 Tesla Siemens Magnetom Concerto MRI equipment. The ACL and PCL were measured at the femoral end, midline, and the tibia end using the computer electronic calipers, and the averages were calculated. The Age and gender - related differences in the cruciate ligament thicknesses were tested using Pearson’s moment correlation coefficient and independent simple t-test respectively at a 5% level of significance. Result: The average ACL thicknesses for male and female subjects were 4.76 ± 0.78 and 4.56 ± 0.89 respectively while the average PCL thicknesses for male and female subjects were 4.76 ± 0.78 and 4.75±0.79 respectively. There were no statistically significant differences (p > 0.005) in mean values of ACL and PCL between male and female subjects respectively. PCL thicknesses increased with age while the ACL thicknesses decreased with age. Age correlated positively with the ACL(r=0.2) as well with the PCL (r =0.4). Conclusion: The growths of the posterior and anterior cruciate ligaments have direct and inverse relationships with age respectively. Male volunteer subjects have thicker cruciate ligaments compared to female volunteer subjects.

Congenital dislocation of the knee, result- ing from an absence of the cruciate ligaments, is  a condition affecting 0.017 per 1000 live births (1).  Although very rare, it has drawn the attention of or- thopaedic surgeons and radiologists because it is  associated with other congential anomalies. This paper presents abnormalities that are isolated to the knee and without evidence of associated syndrome. The absent anterior cruciate ligament (ACL) is associated with a hypoplastic posterior cruciate ligament (PCL), a shallow femoral notch, and hypoplastic tibial spines seen with radiographic and magnetic resonance imaging. The objective of this article is to review the clinical presentation and imaging fndings associated with congenitally absent ACL.

Magnetic resonance imaging has become the gold standard for soft tissue lesions evaluation especially after a traumatic event where there is need for diagnostic confirmation. The objective of the current paper was to evaluate the ability of magnetic resonance imaging in diagnosing soft tissue lesions in patients who underwent anterior cruciate ligament reconstruction compared with arthroscopic findings. Through the ability to diagnose soft tissue injuries, particularly meniscal lesions, magnetic resonance imaging should be considered as fundamental in guiding therapeutic management in patients with anterior cruciate ligament lesions.

Background: Anterior cruciate ligament (ACL) tears are common injuries; they are often associated with concomitant injuries to other structures in the knee, including bone bruises. While there is limited evidence that bone bruises are associated with slightly worse clinical outcomes, the implications of bone bruises for the articular cartilage and the risk of developing osteoarthritis (OA) in the knee are less clear. Recent studies suggest that the bone bruise pattern may be helpful in predicting the presence of meniscal ramp lesions. Evidence Acquisition: A literature review was performed in EMBASE using the keyword search phrase (acl OR (anterior AND cruciate AND ligament)) AND ((bone AND bruise) OR (bone AND contusion) OR (bone AND marrow AND edema) OR (bone AND marrow AND lesion) OR (subchondral AND edema)). Study Design: Clinical review. Level of Evidence: Level 4. Results: The literature search returned 93 articles of which 25 were ultimately included in this review. Most studies identified a high prevalence of bone bruises in the setting of acute ACL injury. Individual studies have found relationships between bone bruise volume and functional outcomes; however, these results were not supported by systematic review. Similarly, the literature has contradictory findings on the relationship between bone bruises and the progression of OA after ACL reconstruction. Investigations into concomitant injury found anterolateral ligament and meniscal ramp lesions to be associated with bone bruise presence on magnetic resonance imaging. Conclusion: Despite the ample literature identifying the prevalence of bone bruises in association with ACL injury, there is little evidence to correlate bone bruises to functional outcomes or progression of OA. Bone bruises may best be used as a marker for concomitant injury such as medial meniscal ramp lesions that are not always well visualized on magnetic resonance imaging. Further research is required to establish the longitudinal effects of bone bruises on ACL tear recovery. Strength of Recommendation Taxonomy: 2.

CONTEXT: A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specific, and anterior cruciate ligament ganglia are usually diagnosed through magnetic resonance imaging or arthroscopy. Not all ganglia diagnosed through magnetic resonance imaging need to undergo surgical treatment: only those that cause clinical signs and symptoms do. Surgical results are considered good or excellent in the vast majority of cases. CASE REPORT: A 29-year-old male presented with pain in the left knee during a marathon race. Physical examination revealed limitation in the maximum range of knee extension and pain in the posterior aspect of the left knee. Radiographs of the left knee were normal, but magnetic resonance imaging revealed a multi-lobed cystic structure adjacent to the anterior cruciate ligament, which resembled a ganglion cyst. The mass was removed through arthroscopy, and pathological examination revealed a synovial cyst. Patient recovery was excellent, and he resumed his usual training routine five months later.
