A computer-based model of the knee was used to study forces in the cruciate ligaments induced by co-contraction of the extensor and flexor muscles, in the absence of external loads. Ligament forces are required whenever the components of the muscle forces parallel to the tibial plateau do not balance. When the extending effect of quadriceps exactly balances the flexing effect of hamstrings, the...

PURPOSE The patients expect optimal knee function after Total Knee Arthroplasty. It is necessary to apply appropriate surgical technique and supervised physical therapy. The optimal management of posterior cruciate ligament remains controversial. Both implant designs, i.e., cruciate retaining and posterior substituting, allow the orthopedic surgeon to achieve excellent clinical outcomes, as mea...

J Babol Univ Med Sci; 18(12); Dec 2016; PP: 7-12 Received: Jun 2 2016, Revised: Jul 27 2016, Accepted: Sep 27 2016. ABSTRACT BACKGROUND AND OBJECTIVE: Nd:YAG laser posterior capsulotomy is a standard method for treatment of posterior capsule opacification (PCO) in adults. However, there is not enough information available regarding the advantages and disadvantages of its conventional techniques...

Objective To evaluate the effectiveness of neuromuscular training in reducing the rate of acute knee injury in adolescent female football players. Design Stratified cluster randomised controlled trial with clubs as the unit of randomisation. Setting 230 Swedish football clubs (121 in the intervention group, 109 in the control group) were followed for one season (2009, sevenmonths). Participants...

the arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. the present article describes the results of arthroscopic examination of 100 patients (mean age 29.4 years 82% male) evaluated from 1996 to 1997 in imam khomeini hospital of tehran. sport injury was the most prevalent cause of referral (40%). the 2 most frequent complaints were knee pain (94%) and ...

Cranial cruciate ligament disease (CCLD) is the most common cause of hindlimb lameness in the dog, being associated with and eventually leading to stifle osteoarthritis. Canine cranial cruciate ligament disease is a gradual degeneration of the ligament extracellular matrix (ECM) leading to ligament rupture. The aetiopathogenesis of this condition is still poorly understood but several risk fact...

Harvesting the central third of the patellar tendon for autograft anterior cruciate ligament reconstruction is thought to compromise quadriceps strength and functional capacity. We compared objective measurements of quadriceps strength and functional capacity in athletes after patellar tendon autograft or allograft anterior cruciate ligament reconstruction. We looked at 33 active male patients ...

Rotating-platform, mobile-bearing total knee arthroplasty was initially developed using a posterior cruciate-sacrificing technique and design. Posterior cruciate-substituting and -retaining, rotating-platform total knee arthroplasty designs were developed later. The purpose of this study was to evaluate a minimum 4-year follow-up of total knee arthroplasty performed with a posterior cruciate-re...

During daily training, shot putters are prone to acute complete anterior cruciate ligament injury, which is mainly treated with early reconstruction under knee arthroscopy to restore stability of injured athletes’ knee as soon as possible, help them towards early recovery and resume normal work and training. During knee arthroscopic treatment, extrusion screws are mainly used for acute complete...

AIM OF THE STUDY Ultrasound examination is widely used in orthopedic diagnostics, however sonographic evaluation of traumatic anterior cruciate ligament insufficiency is still inadequate. Aim of this study is to evaluate diagnostic capability of a new sonographically-guided test for diagnosing complete anterior cruciate ligament insufficiency. MATERIAL AND METHODS In 47 patients, with suspici...
