Editorial Commentary: Isolated Patellofemoral Osteoarthritis May Be Treated Arthroscopically: Arthroscopic Partial Lateral Facetectomy Is a Good Alternative to More Aggressive Techniques.

Isolated patellofemoral osteoarthritis is not uncommon, and treatment remains controversial. Several surgical procedures have been performed to treat this condition. The success of surgery highly depends on the technique and the patient selection.

Cellular and molecular meniscal changes in the degenerative knee: a review.

Background: The important role of knee menisci to maintain adequate knee function is frequently impaired since early stages of knee joint degeneration. A better understanding of meniscal impairment may help the orthopaedic surgeon to orient the treatment of the degenerative knee. This review focuses on changes in meniscal cells and matrix when degeneration is in progress.

Meniscal degeneration in human knee osteoarthritis: in situ hybridization and immunohistochemistry study.

Objective: Meniscus injury is one of the causes of secondary osteoarthritis (OA). However, the role of meniscus is still unclear. Human meniscal distribution of cells and cartilage oligomeric matrix protein (COMP) and their changes in advanced OA were analyzed.

An experimental study of COMP (cartilage oligomeric matrix protein) in the rabbit menisci.

Introduction: Secondary knee osteoarthritis (OA) is currently associated with meniscal injuries, but the pathogenesis is unclear. We analyzed the distribution of cells and cartilage oligomeric matrix protein (COMP) and its changes in the early stages of degeneration in meniscus.

Method: Ten New Zealand rabbits underwent anterior cruciate ligament (ACL)-transection of the right knee-joint.

Multicentric myxoid liposarcoma: report of two cases.

Background: Multicentric myxoid liposarcoma is a rather infrequent tumour that tends to behave aggressively.

Case Presentation: We herein report two further cases of this tumour that have been managed in our Hospital. Both were young men with multiple sites of involvement at the moment of diagnosis and both have shown a bad prognosis with frequent recurrences after treatment and rapid death in one case.

Clinical and radiologic outcomes of surgical and conservative treatment of type III acromioclavicular joint injury.

The management of acute acromioclavicular joint dislocations is controversial. The purpose of this study was to compare the incidence of posttraumatic anatomic alterations after surgical or conservative treatment of type III injuries and to analyze their effect on the outcome. Forty-three patients were evaluated retrospectively, clinically and radiographically, at a 12-month minimum follow-up.

Legg-perthes disease and heritable thrombophilia.

The etiology of Perthes' disease is unclear. Recent reports have suggested that inheritable thrombophilic disorders may be one of its pathogenetic causes. The G20210A prothrombin gene, factor V Leiden, and MTHFR C677T mutations have been identified as predisposing genetic factors for thrombosis.
