OBJECTIVE To evaluate change over time of clinical scores, morphological MRI of cartilage appearance and quantitative T2 values after implantation with BioCart™II, a second generation matrix-assisted implantation system. METHODS Thirty-one patients were recruited 6-49 months post surgery for cartilage defect in the femoral condyle. Subjects underwent MRI(More)
Because of their complexity, war injuries inflicted by a blast mechanism often require tailoring of treatment to attain a more individualized solution. We report two cases of bilateral, severely mangled lower limbs with open tibial fractures and crush injuries to the feet. In each case, one limb had to be amputated below the knee, but the other limb was(More)
Osgood-Schlatter disease is a well-known condition in late childhood characterized by pain over the tibial tubercle. This condition usually resolves spontaneously at skeletal maturity. Few patients develop pain over the tibial tubercle. Radiological examination demonstrates a round regular ossification over the tubercle. Treatment is usually symptomatic,(More)
One of the most devastating complications of prosthetic knee arthroplasty is a periprosthetic infection. This complication occurs in 1-2% of knee arthroplasties [1,2] and can exceed 4% in immunocompromized individuals [3] and 7% after revision surgery [4]. Prosthetic infection leads to loosening of the implant, [5,6]. In this circumstances revision surgery(More)
BACKGROUND The introduction of bio-absorbable materials has improved the ability to offer a simple fast and friendly solution to meniscal tears. The technique of meniscal suture with bio-absorbable arrows is associated with lower morbidity and complication rates. AIM The clinical evaluation of treatment of meniscal tear by suture with bio-absorbable(More)
