background osteoarthritis (oa) is a multifactorial, disabling and degenerative disease that worsens with age and affects patient’s health-related quality of life (hrqol). objectives the current study aimed to assess if age and comorbidities have an influence on knee oa and knee replacement outcome before and after the surgery. methods a quasi-experimental intervention study was conducted on a s...

juvenile idiopathic arthritis is the leading cause of hip replacement in young children. however, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. in this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...

BACKGROUND A meta-analysis was conducted to evaluate the effectiveness of three surgical modalities-gap arthroplasty (GA), interpositional gap arthroplasty (IPG) and joint reconstruction (AR)-in treating temporomandibular joint (TMJ) ankylosis. METHODS A systematic review was performed using the PUBMED, EMBASE and OVID search engines in February 2015 to identify cohort studies with no restric...

INTRODUCTION Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. PURPOSE To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or al...

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...

INTRODUCTION Temporo-mandibular joint ankylosis is a common cause of acquired deformity in children. PURPOSE Surgical correction of the ankylosis only leaves the patient with an uncorrected mandibular deformity. This study was to evaluate the use of distraction osteogenesis for simultaneous correction of the mandibular deformity. MATERIAL This study was done on six children with temporo-man...

INTRODUCTION Mechanical alignment deviation after total knee arthroplasty is a major reason for early loosening of the prosthesis. Achieving optimum cement penetration during fixation of the femoral and tibial component is an essential step in performing a successful total knee arthroplasty. Bone cement is used to solidify the bone and prosthesis. Thickness imbalance of bone cement leads to the...

Ankylosis of the temporomandibular joint (TMJ) is characterized by a bony or fibrous fusion between articular fossa and condyle. It represents one greatest therapeutic challenges in oral maxillofacial surgery. Several treatments have been used for its management, such as gap arthroplasty, interpositional TMJ reconstruction with autogenous bone graft alloplastic prostheses. A 39-year-old Black m...

Objective: Our aim was to establish the existence of intercellular communication through gap junctions (ICGJ) in synovial tissues and to show that gap junction communications in synovial tissue plays a role in the pathogenesis of synovitis in patients with rheumatoid arthritis (RA). Material and methods: Synovial tissues were obtained from patients with RA and osteoarthritis (OA) at the time of...
