Background: Osteoarthritis is the most common joint disorder in the world that will affect nearly half of all adults by age 85. The appropriate management in patients with mild to severe osteoarthritis still remains a challenging area where viscosupplementation (SYNVISC) can play an important role. Hypothesis/Purpose: To analyze the efficacy of intra-articular injections of SYNVISC (Hylan G-F 2...

BACKGROUND The study aimed to assess long-term clinical outcomes of cartilage lesion treatment with blood stem cells. The analysis of complications of this method was an additional aim. MATERIAL AND METHODS The study group comprised 52 patients with ICRS grade III or IV lesions of 4 to 12 cm2. The assessment was carried out at one and six years following the surgery with the use of KOOS and L...

background: the aim of this study is evaluation of the validity and reliability of the persian version of knee injury and osteoarthritis outcome score (koos) in patients with isolated meniscus injury. materials and methods: one hundred people with isolated meniscal injury (29 females and 71 males with a mean age ± standard deviation [sd] = 32.37 ± 9.97 years) and ?fty normal people with no knee...

INTRODUCTION Knee osteoarthritis is associated with persistent joint pain, stiffness, joint deformities, ligament damage, and surrounding muscle atrophy. The complexity of the disease makes treatment difficult. There are no therapeutic drugs available to halt the disease progression, leaving patients dependent on pain medication, anti-inflammatory drugs, or invasive joint replacement surgery. ...

OBJECTIVES To assess the validity of the Oxford Knee Score (OKS) for use in patients undergoing non-operative management for their knee osteoarthritis (OA) within the National Health Service (NHS). DESIGN Observational cohort study. SETTING Single orthopaedic centre in England. PARTICIPANTS 134 patients undergoing non-operative management for knee OA. MAIN OUTCOME MEASURES OKS, the Inte...

BACKGROUND The WOMAC is the most widely used self-report measure to evaluate physical functioning in hip or knee osteoarthritis, however its ability to discriminate pain and physical functioning (i.e. discriminate validity) has repeatedly been questioned. Little to no data is available on the discriminant validity of alternative questionnaires that measure the same construct, for instance the H...

BACKGROUND Total knee arthroplasty in joints with valgus or varus deformity is technically demanding. Careful soft tissue balance as well as restitution of anatomical knee axis has a profound effect on postoperative function of the joint, however little is known about differences in subjective stability following surgery between preoperative valgus and varus knees. MATERIAL AND METHODS Studie...

Background and purpose - Knee pain after total knee arthroplasty (TKA) is not uncommon. Patellar retention in TKA is one cause of postoperative knee pain, and may lead to secondary addition of a patellar component. Patellar resurfacing in TKA is controversial. Its use ranges from 2% to 90% worldwide. In this randomized study, we compared the outcome after patellar resurfacing and after no resur...

OBJECTIVE To compare, in young active adults with an acute anterior cruciate ligament (ACL) tear, the mid-term (five year) patient reported and radiographic outcomes between those treated with rehabilitation plus early ACL reconstruction and those treated with rehabilitation and optional delayed ACL reconstruction. DESIGN Extended follow-up of prospective randomised controlled trial. SETTIN...

BACKGROUND Successful return to sport is an important outcome measure after anterior cruciate ligament (ACL) reconstruction and a reason for patients' decisions to elect surgery. Rehabilitation programs supervised by physical therapists are routinely prescribed after ACL reconstruction surgery. However, the added advantage of supervised physical therapy after ACL reconstruction is still debatab...
