The osteochondral healing potential of hyaluronic acid (HA) plus diacerein was evaluated in subchondral-drilling- (SCD-) induced fibrocartilage generation in rabbits. A full-thickness chondral defect was created along the patellar groove of both knees and then SCD was subsequently performed only in the left knee. A week later, the rabbits were allocated into 3 groups to receive weekly intra-art...

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of ana...

We investigated the changes in surface roughness of retrieved femoral components in 18 men and four women at revision knee surgery. The mean age at revision was 68.4 years and the mean period of implantation was for 55.6 months. Eighteen implants were retrieved for aseptic loosening and four for infection. The surface changes in the articulating areas were inspected visually and the roughness (...

Objectives: Patellar dislocations are associated with patellofemoral cartilage degradation following injury and a high risk of post-traumatic osteoarthritis (PTOA). Obesity is also primary factor for OA, but the influence obesity on follow patellar unknown. The current study uses T1ρ-based relaxation time mapping to evaluate body mass index (BMI) properties in acute phase dislocation, compares ...

INTRODUCTION The tibial tuberosity to trochlear groove (TTTG) distance in the western population is extensively studied through various modalities such as X-rays, computerised tomography and magnetic resonance imaging. However, to our knowledge there is very little or no literature support to indicate that TTTG distance has been studied in the Indian population. METHODS We therefore undertook...

Objective- To evaluate the biological compatibility of differentiated stem cells embedded in poly-vinyl-alcohol (PVA) scaffolds for repair of distal femoral cartilage defect.   Design- Experimental in vivo study. Animals- Twelve adult male New Zealand white rabbits were used which were divided into two groups (I, II) six rabbits each.   Procedures- Mesenchymal stem cells were isolated from h...
