abstract: knee joint has major role in lower extremity activities. emong different elements of knee joint complex, anterior cruciate ligament has becom more interested because of its alignment, structural complication, varied never receptors and frequently susceptibility to injury. afterinjury of this ligament knee extensor torque decreases. the aim of this research was that reduce of quadricep...

Few studies have assessed the results of autologous chondrocyte implantation in patients with high-impact activities. The purpose of this study was to evaluate the early functional outcome and activity level after 2-stage autologous chondrocyte implantation in professional soldiers and athletes. Nineteen patients with an average age of 32.2 years were treated with autologous chondrocyte implant...

BACKGROUND Transplantation of mesenchymal stem cells (MSCs) is one possible strategy to achieve articular cartilage repair. We previously reported that synovial MSCs were highly proliferative and able to undergo chondrogenesis. We also found that placing a suspension of synovial MSCs on a cartilage defect for 10 minutes promoted cartilage repair in rabbit and pig models. However, the in vivo ef...

PURPOSE The goal of this study was to evaluate the clinical outcome of single-bundle posterior cruciate ligament (PCL) reconstruction with retention of the PCL remnant and hamstring tendon autograft with interference screw fixation in patients with isolated PCL laxity. TYPE OF STUDY Prospective case series with minimum 2-year follow-up evaluation. METHODS Thirty-one patients for whom conser...

Abstract Background Lateral augmentation (LA) of anterior cruciate ligament reconstruction (ACLR) aims to improve the anterolateral stability knee and patient functional outcomes while reducing complication rates. Despite growing evidence popularity, there have been no studies directly comparing main two methods LA; extra-articular tenodesis (LEAT) Anterolateral (ALLR). Aim To establish level I...

OBJECTIVE Knee cartilage defects represent a socioeconomic burden and may cause lifelong disability. Studies have shown that cartilage defects are detected in approximately 60% of knee arthroscopies. In clinical trials, the majority of these patients are excluded. This study investigates whether patients included in randomized controlled trials (RCTs) represent a selected group compared to gene...

PURPOSE To compare clinical and radiographic results of anterior cruciate ligament (ACL) reconstruction using modified transtibial technique (mTT), anteromedial (AM) portal technique and outside-in (OI) technique. MATERIALS AND METHODS From March 2007 to December 2012, ACL reconstruction was performed using the mTT, AM portal technique and OI technique in 20 patients each. Anteroposterior and...

BACKGROUND At present, there are no registered products for the treatment of subchondral Bone Marrow Edema Lesion (BML) and associated knee pain. Patients who do not respond to current anti-inflammatory therapies are left with limited treatment options, and may resort to operative management with Total Knee Arthroplasty (TKA). We report the use of Pentosan Polysulphate Sodium (PPS) for the trea...

BACKGROUND Patellar tendinopathy can be treated surgically for patients that have failed at least 1 year of nonoperative treatment who continue to have debilitating symptoms. Patellar tendinopathy can cause significant functional deficits, yet little has been reported about the operative treatment of patellar tendinopathy. HYPOTHESIS A combined arthroscopic and open surgical technique for the...

This is a retrospective case-control study of arthroscopic partial meniscectomy for isolated lesions of the lateral meniscus, performed between 1990 and 1995. Thirty-one knees were evaluated after an average follow-up of 8 years: 48.4% had excellent/good IKDC-scores and 64.5% excellent/good Lysholm scores. The Tegner activity score dropped from 7.2 (competitive sports) to 5.7 (recreational spor...
