Purpose: To analyze the results of the use of intra-articular cultured autologous bone marrowederived mesenchymal stem cell (MSC) injections in conjunction with microfracture and medial opening-wedge high tibial osteotomy (HTO). Methods: Fifty-six knees in 56 patients with unicompartmental osteoarthritic knees and genu varum were randomly allocated to the cell-recipient group (n 1⁄4 28) or cont...

INTRODUCTION Most current cell-based cartilage repair techniques require some form of scaffolds and 2 separate surgical procedures. We propose a novel, scaffold-less technique of cartilage repair in the human knee that combines arthroscopic microfracture and outpatient intra-articular injections of autologous bone marrow-derived mesenchymal stem cells (MSCs) and hyaluronic acid (HA). MATERIAL...

We carried out a prospective study of 71 patients who had undergone reconstruction of the anterior cruciate ligament with the ABC scaffold. Their mean age was 28 years (18 to 50). All had either sub-acute or chronic traumatic deficiency of the ligament. The mean period of follow-up was five years (four to seven). Assessment included the use of the International Knee Documentation Committee scor...

BACKGROUND The meniscus plays a key role in the functioning of the knee. At the present time, meniscal repair has becomes the main treatment for meniscal tear. Compared to open surgery, arthroscopic meniscal repair has become popular because of shorter time need for the operation, the smaller wound, and better accessibility to the tear portion, which is particularly difficult during open surger...

BACKGROUND The Lysholm knee scale, first published in 1982, is an eight-item questionnaire designed to evaluate patients after knee ligament injury. However, as a tool developed in English, its use as a validated instrument has been limited to English-language populations. QUESTIONS/PURPOSES The objectives of this study were to test the ease of use, reliability, and validity of a Turkish-lang...

The aim of this study was to examine proprioception with and without muscle tension and knee function in two groups of chronic (> 1 year post-injury) patients with deficient anterior cruciate ligaments with distinctly different functioning levels. The well (WF) and poor functioning (PF) group was defined as those with a Tegner/Lysholm score equal to or greater than 6/95 (WF, n = 7), and equal t...

INTRODUCTION The Nintendo Wii game console is already used as an additional training device for e.g. neurological wards. Still there are limited data available regarding orthopedic rehabilitation. The authors' objective was to examine whether the Nintendo Wii is an appropriate and safe tool in rehabilitation after orthopedic knee surgery. MATERIAL AND METHODS A prospective, randomized, contro...

OBJECTIVE The purpose of this article is to describe and recommend patient-reported outcome instruments for use in patients with articular cartilage lesions undergoing cartilage repair interventions. METHODS Nonsystematic literature search identifying measures addressing pain and function evaluated for validity and psychometric properties in patients with articular cartilage lesions. RESULT...

BACKGROUND Several instruments and clinical scoring systems have been established to evaluate patients with ligamentous knee injuries. A comparison of individual articles in the literature is challenging, not only because of heterogeneity in methodology, but also due to the variety of the scoring systems used to document clinical outcomes. There is limited information about the correlation betw...

BACKGROUND In recent years, the scientific discussion has focused on new strategies to enable a torn anterior cruciate ligament (ACL) to heal into mechanically stable scar tissue. Dynamic intraligamentary stabilization (DIS) was first performed in a pilot study of 10 patients. The purpose of the current study was to evaluate whether DIS would lead to similarly sufficient stability and good clin...
