In the years 1940-55 inclusive 2,668 semilunar cartilages were removed by surgeons working as a team and with a similar outlook on the internal derangements of the knee. The detailed records of the cartilages removed show that a relatively small proportionnamely 4#{149}5 per cent-had no detectable lesion. This proportion nevertheless represents 1 19 cases. The purpose of this paper is to record...

BACKGROUND The goal of total knee arthroplasty (TKA) is to restore knee kinematics. Knee prosthesis design plays a very important role in successful restoration. Here, kinematics models of normal and prosthetic knees were created and validated using previously published data. METHODS Computed tomography and magnetic resonance imaging scans of a healthy, anticorrosive female cadaver were used ...

BACKGROUND Rupture of the anterior cruciate ligament (ACL) is a common sports injury and is known to be associated with an increased risk of knee osteoarthritis. Several studies have indicated that the risk of additional injuries to the menisci and articular cartilage increases with delays in the treatment of ACL tears. However, no consensus has been reached regarding the ideal timing for ACL r...

Dear Editor, The menisci are important tissues in the healthy knee due to their shock absorption and load distribution properties. Meniscal tears are important clinically due to pain and swelling and the mechanical symptoms they cause such as locking. The arthroscopic anatomical classifi cation of meniscal tears was described by Dandy in 1990.1 In the paper, he noted that the majority (69%) of ...

he menisci of the human knee are fibrocartilaginous, crescent-shaped structures that lie on the articular surface of the tibia (Figure 1). They are integral components of knee biomechanics. Injuries to the knee menisci are common, especially among athletes. Short-term sequelae of meniscal injury include knee pain and deficits in knee range of motion. Long-term sequelae may include degenerative ...

Examination of the menisci in knee joints. Dr. P. Miiller (Zntralbl. F. Chir., 1933, no. 35) observed annunciation 1% cases with simultaneous existence artritis deformans patients.

Half-time seminar Elin Folkesson Proteomics of the meniscus and the importance of the meniscus in osteoarthritis Background Osteoarthritis (OA) is one of the most common joint diseases in the world, and there is currently no disease-modifying treatment available. Meniscectomy or arthroplasty are the most common treatments at orthopedic clinics. The knowledge about the early development of OA an...

The existence of abnormal-shaped menisci has been long recognized. The presence of discoid menisci in the human knee is considered to be a congenital malformation with a very low rate of incidence except in Asian populations. Since the publication of Watanabe's Atlas, three types of lateral meniscal abnormalities are generally accepted: the complete and incomplete discoid, as well as the Wrisbe...

INTRODUCTION The knee menisci are critical to the distribution of tibiofemoral contact stresses. This is demonstrated by the deleterious effects of injury or menisectomy on articular cartilage. Meniscus strains reflect load transfer and function in the normal and injured joint, and measurement of strain can be used to assess the efficacy of surgical repair techniques. However, in vivo measureme...
