BACKGROUND: There have been very few reports on isolated medial tibial plateau osteonecrosis, and the condition has not been clearly described. Unicompartmental knee arthroplasty (UKA) may be an appropriate treatment method for this condition. The aims of this study were to report our experience of using mobile-bearing knee implants for osteonecrosis of the medial tibial plateau and to discuss the etiology and treatment of this type of osteonecrosis. METHODS: This study included six consecutive patients with isolated medial tibial plateau osteonecrosis treated with an Oxford mobile-bearing knee implant...

PURPOSE: Recently, it has been recognized that meniscocapsular ('ramp') lesions of the posterior one-third of the medial meniscus frequently occur during injuries causing ACL rupture, and that these lesions are easily missed at arthroscopy. Furthermore, it is clear that these lesions are biomechanically significant, adding to the deficits caused by ACL rupture, and that their repair can reverse this. The efficacy of an all inside repair technique has been questioned by some authors and by those who advocate a suture shuttle technique via an accessory posteromedial portal...

EDITORIAL
Romain Seil
Thirty-five years after their initial description, ramp lesions of the medial meniscus in anterior cruciate ligament (ACL)-deficient knees are slowly being rediscovered. Routinely repaired in open ACL and peripheral reconstructions before the era of arthroscopic ACL reconstruction, ramp lesions have been largely ignored in the last 2 decades. Following the growing number of studies analyzing the causes of residual laxity after ACL reconstructions over the last decade, ramp lesions are increasingly being implicated, and thus investigated, but remain poorly understood...

While interpreting routine magnetic resonance imaging (MRI) of the knee joint, a radiologist may encounter various cystic lesions such as ganglion, synovial, and meniscal cysts, among others. In some cases, MRI may demonstrate cystlike lesions around the knee due to fluid distention of normal bursa and recesses, the diagnosis of which should not be difficult if a radiologist is familiar with their characteristic location and MRI appearance. In addition, there are cyst mimickers such as hematomas, abscesses, vascular lesions, and neoplasms around knee joint that may pose a diagnostic challenge on routine MRI...

Purpose: To identify early determinants of clinical outcome after knee cartilage repair. Methods: 205 patients were evaluated before surgery and at median 14-years follow-up. Results: Baseline factors predicting a good outcome were: single lesion; normal appearing cartilage surrounding the lesion; high baseline Lysholm score; short duration of symptoms; non-involvement of the patella-femoral joint; young age; and small defect. Factors predicting a poor outcome were: multiple lesions; low baseline Lysholm score; degenerative cartilage surrounding the lesion; long symptom duration; meniscal lesion; and large defect...

BACKGROUND: The meniscus plays an important role in the integrity of the knee joint. Therefore, meniscus tissue preserving techniques for the therapy of meniscus injuries seem to be reasonable. One of the important questions is whether meniscal repair can prevent the knee joint from early onset of osteoarthritis. METHODS: According to the review of the current literature, the principles of a successful meniscal repair are explained and the functional outcome and its impact on the prevention of osteoarthritis are analyzed in this article...

BACKGROUND: Static anterior tibial subluxation of the lateral compartment after an anterior cruciate ligament (ACL) injury highlights an increased anterior position of the tibia relative to the femur. However, the precise cause of this phenomenon is not entirely clear. Recently, an increased posterior tibial slope (PTS) has been identified as an independent risk factor for noncontact ACL injuries. HYPOTHESIS: An increased PTS is associated with an increased anterior position of the lateral compartment of the tibia relative to the femur after acute ACL injuries...

A meniscal injury should not automatically lead to surgery. Even in light of all the developments in arthroscopic surgery, non-operative management still has a place in the treatment algorithms for lesions around the knee. In this second publication of the German guidelines for meniscal surgery, the authors describe the various treatment possibilities, their indications and offer critical insight into the various therapeutic options. This will allow the patient and physician alike to make the proper individual decisions...

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...
