The medial collateral ligament of the knee joint is one of the most commonly injured ligaments of the knee. Recent data have shown that the thin layer of connective tissue covering the ligament, known as the epiligament, is essential for its nutrition and normal function, as well as its healing after injury. The aim of the present study was to investigate and compare the changes in the epiligament of the medial collateral ligament which occurred during operative and non-operative treatment throughout the first month after injury. We used 27 male Wistar rats randomly allocated to three groups. In the 9 rats belonging to the first group, the medial collateral ligament was fully transected and left to heal spontaneously without suture. In the 9 rats belonging to the second group, the transected ends were marked with a 9–0 nylon monofilament suture. The 9 rats in the third group were used as normal controls. Three animals from each group were sacrificed on days 8, 16, and 30 after injury. Light microscopic analysis was performed on semi-thin sections stained with 1% methylene blue, azure II, and basic fuchsin. Transmission electron microscopy was used to study and compare the ultrastructural changes in the epiligament. The statistical analysis of the obtained data was performed using the Kruskal-Wallis H test and Mood’s median test. The normal structure of the epiligament of the medial collateral ligament was presented by fibroblasts, fibrocytes, adipose cells, mast cells, collagen fibers, and neuro-vascular bundles. On days 8 and 16 postinjury, the epiligament appeared hypercellular and returned to its normal appearance on the thirtieth day postinjury. The electron microscopic study revealed the presence of different types of fibroblasts with the typical ultrastructural features of collagen-synthetizing cells. The comparative statistical analysis on the respective day showed that there was no statistically significant difference in the number of cells between spontaneously healing animals and animals recovering with suture application. These data further prove that spontaneous healing of the medial collateral ligament yields similar results to surgical treatment and may be used as a basis for the development of treatment regimens with improved patient outcome.

Abstract Soft-tissue calcification is characterised by the deposit of calcium in the damaged collagen fibres. The pathology of the phenomenon is not fully known. Trauma, spinal cord injury and traumatic brain injury have been reported as possible risk factors. Hypertrophic calcification of medial collateral ligament can be post-traumatic with unexplained aetiology. It can restrict the normal range of joint motion, affecting performance of activities of daily living, resulting in disturbance of quality of life. It may be managed conservatively, but if unsuccessful, surgical removal of the calcification may be carried out. Here, we present a case of post-traumatic heterotrophic calcification of medial collateral ligament of knee joint and review of current literature.

The primary diabetes-related health concerns are neuropathy and cardiovascular changes. Connective tissue changes can also affect quality of life by increasing ligament and joint capsule stiffness, impairing proprioception, limiting function, and leading to greater risk of falling. Our objectives were to evaluate effects of Type I diabetes and exercise on medial collateral ligament properties and overall knee-joint stiffness and stress relaxation. Thirty-four male Sprague–Dawley rats, approximately two months old, were divided into three groups—sedentary controls (n=10), sedentary diabetics (n=10) and exercised diabetics (n=14). Diabetes was induced by streptozotocin injection. Exercised rats ran 5 days/week, 1 hr/day, at 20 m/min. All animals were sacrificed seven weeks after induction of diabetes. Stiffness and stress relaxation of the whole knee joint was tested in distraction and anterior–posterior tibial displacement. The joint capsule and knee ligaments were then sectioned, preserving the medial collateral ligament (MCL). The MCL structural properties were tested by knee distraction at a flexion angle of 40°. Whole joint stiffness was 23% higher for anterior tibial displacement in the exercised diabetic group, and 31% higher for posterior tibial displacement, compared to controls. Whole joint stress relaxation in distraction was 25% lower for the exercised diabetic group. No differences were found for MCL properties. Diabetes and exercise clearly increased joint stiffness. The effects may be due to tissue adaptation, but appear more likely to be due to increased blood flow that promotes increased tissue glycation in the joint capsule.
