Some reported bearing fractures are due to entrapment of the bearing between the femoral component and posterior edge of the tibial base plate in unstable meniscal –bearing design TKA. However, so far no cases of bearing fracture has been reported for the rotating platform or anteroposterior gliding designs of mobile bearing TKA. The authors describe two cases of polyethylene stress fracture af...

background there is controversy regarding routine prophylaxis for deep vein thrombosis (dvt) in patients treated via a short leg cast or splint following lower extremity trauma. results there were 95 patients with an average age of 38 ± 13.7 (77.9% males); 46 patients had at least one risk factor for dvt. the d-dimer test was positive in 21(22.1%) patients. dvt was confirmed by due in 3 patient...

introduction: knee osteoarthritis (ko) is the most common joint disease for which there is no optimal treatment. monochromatic infrared photo energy (mipe) is a relatively new light modality used to reduce pain and increase circulation. low level laser therapy (lllt) is another light modality used to reduce pain in ko. methods: the aim of this study was to compare the effects of the mipe and ll...

background:   patellofemoral pain syndrome (pfps) is defined as pain surrounding the patella when sitting with bent knees for prolonged periods of time or when performing activities like ascending or descending stairs, squatting or   athletic activities. patella dislocation is not included in pfps.     purpose:   this review analyzes the evidence based conservative management of pfps.   methods...

the clinical use of prp therapy in the practical setting of orthopaedic fields is increasing partly because of the accessibility of devices that are used in outpatient preparation and delivery. another reason is the strong advertisement of prp procedures as the ultimate treatment and novel technology for knee problems by a few orthopaedic surgeons based on claims of abundant scientific evidence...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

background: osteoarthritis is a disabling musculoskeletal disease with no definite treatment. this study compared the effect of platelet-rich plasma (prp) and transcutaneous electrical nerve stimulation (tens) plus exercise in the treatment of patients with knee joint osteoarthritis.   methods : 54 eligible patients with knee osteoarthritis were randomly allocated into two groups. (irct20121106...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...

To investigate the effect of instability on the remodelling of a minor articular surface offset, we created a 0.5 mm coronal step-off of the medial femoral condyle in 12 New Zealand white rabbits and transected the anterior cruciate ligament (ACL). A control group of 12 rabbits had only ACL resection and the opposite knee was used as the non-operated control. The osteoarthritic changes at 6, 12...

BACKGROUND The purpose of this study was to evaluate the functional and radiographic outcome of fixation of unstable juvenile osteochondritis dissecans lesions of the knee after a minimum of 2 years of follow-up. METHODS A total of 33 unstable juvenile osteochondritis dissecans lesions in 30 patients underwent fixation using bioabsorbable pins through arthrotomy or under arthroscopy. The pati...
