[In vitro evaluation of the maximal possible deformation imposable on the median collateral ligaments in rabbits].

With this study, we identified the maximal level of deformation applicable to medial collateral rabbit ligaments in vitro. According to scanning electron microscopy photographs of ligaments fixed at different elongation level 0% (n = 5), 5% (n = 4), 6% (n = 5), 8% (n = 5), 10% (n = 7), 15% (n = 4) and 20% (n = 4), we concluded that a 6% deformation would be optimal. At that level, the collagen fiber undulation are completely unstretched, and still, no collagen ruptures could be observed.

Management of medial collateral ligament laxity.

Assessment of axial alignment with 3-foot radiographs and valgus-varus stress radiographs is important when managing symptomatic MCL instability. Realignment of the anatomical axis to 0 degrees to reduce the stress on the MCL reduces the symptomatic laxity. The assessment of MCL laxity is important when considering valgus HTO for medial compartment arthritis. A combined opening and closing wedge osteotomy reduces the size of the fragment needed and tensions the MCL at the same time. Interposition proximal tibial allografts may be used to retention combined MCL/LCL laxity as well as to correct associated deformities. As one would expect, defunctioning of the MCL in patients with valgus is best achieved using a varus distal femoral osteotomy.

[Injuries of the medial collateral ligament and anterior cruciate ligament of the knee joint and its surgical-functional treatment using the Lemaire technic].

The operative-functional treatment of ligamentous tears of the knee joint avoids additional damage due to immobilisation and shortens the rehabilitation period. The basic idea and details of the Lemaire operations are explained. With an average follow up time of 3.5 years, 113 ligamentous plasties mainly for recent tears of the medial collateral and anterior cruciate ligament have been clinically and radiologically assessed by an independent surgeon. Excellent and good results were obtained in 80 to 90% of the patients. The lateral plasty for torn anterior cruciate ligaments prevents successfully antero-lateral subluxation and thus protects the menisci from tear and the cartilage from degenerative alteration. No obvious increase of torn menisci and degenerative signs could be detected in our series of evaluated knees. The Lemaire procedure for old and recent tears of the medial collateral and the anterior cruciate ligament carries little operative risk and inconvenience for the patient and is indicated in any age group, for the young patient as well as for the older but still active person. We recommend the Lemaire operation as an alternative method in treating ligamentous injuries of the knee joint.
