Matrix-Applied Characterized Autologous Cultured Chondrocytes Versus Microfracture: Two-Year Follow-up of a Prospective Randomized Trial.

Background: Randomized controlled trials studying the efficacy and safety of matrix-applied characterized autologous cultured chondrocytes (MACI) versus microfracture (MFX) for treating cartilage defects are limited.

Purpose: To compare the clinical efficacy and safety of MACI versus MFX in the treatment of patients with symptomatic cartilage defects of the knee.

Study Design: Randomized controlled clinical trial; Level of evidence, 1.

Comparison of the cellular composition of two different chondrocyte-seeded biomaterials and the results of their transplantation in humans.

Our study compares the histological and immunohistochemical cellular composition of two different chondrocyte-seeded biomaterials and the results of their transplantation. Our study cohort included 21 patients, comprising 19 men and two women with a mean age of 32 years, who were affected by single chondral lesions of the femoral condyles. These patients were enrolled in our study and treated with arthroscopic implantation of the tissue Hyalograft C and/or Brno culture.

Cruciate ligaments in proximal femoral focal deficiency: arthroscopic assessment.

Background: Because there is limited information concerning the cruciate ligaments in proximal femoral focal deficiency, knee arthroscopy was used to identify the changes of cruciate ligaments and their relation to the different types of this deficiency.

Methods: Knee arthroscopy was performed in 21 consecutive patients with deficiency types III, IV, VII-IX using the Pappas classification. A new classification of the knee was created.

[Ipsilateral traumatic dislocation of hip and knee joints. Case report].

Traumatic obturator dislocation of the hip without fracture associated with antero-lateral knee dislocation is considered to be an extreme injury. Such a case, which has never been treated in our department, is reported here. The patient was a 40-year-old man who suffered his injury in a motorcycle accident.

[Total hip replacement from a MIS-AL approach (comparison with a standard anterolateral approach)].

Purpose Of The Study: Minimally invasive surgery (MIS) techniques have recently become a powerful and effective marketing instruments that are often perceived by the patient as the criterion of the surgeon's and institution's standard. In addition to studies reporting the benefits of minimally invasive procedures, some authors have recently found no such benefits or even pointed out some disadvantages. In this paper we present our own view of this issue.
