PURPOSE The purpose of this study was to evaluate the clinical and imaging results of patients who received intra-articular injections of autologous mesenchymal stem cells for the treatment of knee osteoarthritis. METHODS The study group comprised 18 patients (6 men and 12 women), among whom the mean age was 54.6 years (range, 41 to 69 years). In each patient the adipose synovium was harveste...

PURPOSE The purpose of this study was to compare clinical outcomes after single-bundle anterior cruciate ligament (ACL) reconstruction with a free Achilles tendon allograft using either a transtibial or an anteromedial portal technique and then to quantify the difference in femoral tunnel position between these 2 approaches. This assessment was to be performed with a new method using convention...

AIMS The present study aims to investigate the clinical outcomes of arthroscopic suture fixation in treating tibial eminence fracture with a retrospective study design of two years' follow-up. METHODS A total of 33 patients with imaging evidence of tibial eminence avulsion fractures who underwent arthroscopic surgery between 2008 and 2012 were included in this study. The inclusion criteria fo...

BACKGROUND Anterior knee pain is one of the most common musculoskeletal complaints of young patients. We notice that some patients had normal femoral trochlear, medial and lateral patellar retinaculum, and special patellar morphology, which resulted in a series of symptoms in the flexion of the knee due to the impingement of the lateral articular surface of the patella with the femur. We firstl...

Background:  Despite the introduction of different techniques for meniscal repair, no single procedure is superior in all situations. The new method for meniscal repair named “ modified outside-in technique ” aims to achieve higher primary fixation strength by an alternative suture technique as well as avoid disadvantages of outside-in, inside-out, and all-inside suture procedures. Additionally...

PURPOSE OF THE STUDY Retrograde nailing represents an established fixation method for fractures of the distal femur and offers in femoral shaft fractures an alternative to the existing technique of antegrade nailing. The aim of this study was to investigate in a retrospective analysis the results of retrograde nailing in distal femoral fractures and selected cases of femoral shaft fractures. Em...

Treatment of osteochondral defects in weight-bearing areas of the knee, especially when they are sizeable and involve considerable subchondral bone loss, is a challenging problem. We report our experience on the use of osteochondral allografts with the MEGA-OATS technique in the management of large osteochondral defects of the knee in young patients. Five patients (3 male and 2 female) were inc...

OBJECTIVE To evaluate the surgical aspects that may offer good anatomic and functional results in posterior cruciate ligament (PCL) reconstruction using an autologous graft of the quadriceps tendon and double semitendinosus through a double femoral tunnel. METHODS Fourteen patients with isolated PCL lesions, instability and pain were operated on by arthroscopy and evaluated according to the I...

BACKGROUND The management of severe patellofemoral arthritis in young patients remains a significant problem. For many, patellofemoral replacement is not a desirable option. Current surgical techniques for patellectomy disrupt the extensor lever arm causing weakness. We describe a new technique that maintains the extensor mechanism tension and a case series showing good results for patella-only...

OBJECTIVE The aim of the study was to: 1) evaluate the differences in pre-post operative knee functioning, mechanical stability, isokinetic knee muscle strength in simultaneous arthroscopic patients after having undergone an anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) with hamstring tendons reconstruction, 2) compare the results of ACL/PCL patients with the contro...
