BACKGROUND The medial collateral ligament (MCL) is the main static stabilizer of the medial knee. The surgical treatment was recommended in cases with serious medial collateral ligament insufficiency combined with multi-ligament injuries and chronic symptomatic medial instability. Several surgical techniques have been described for the MCL reconstruction, while potential problems including dono...

Primary knee osteoarthritis (OA) is one of the degenerative diseases that destroy auricular cartilage within knee joint and cause pain, varies deformity, decrease knee function. Total knee arthroplasty (TKA) is an effective intervention in order to relieve pain, improve function and QOL (quality of life) in patients with severe osteoarthritis of the knees that have different degrees of varus de...

We reviewed 34 knees in 24 children after a double-elevating osteotomy for late-presenting infantile Blount's disease. The mean age of patients was 9.1 years (7 to 13.5). All knees were in Langenskiöld stages IV to VI. The operative technique corrected the depression of the medial joint line by an elevating osteotomy, and the remaining tibial varus and internal torsion by an osteotomy just belo...

Objective: To ascertain whether spiking of the tibial tubercles is associated with cartilage defects as detected by magnetic resonance imaging (MRI) in osteoarthritis (OA) of the knee joint patients. Methodology: The study was performed on 76 knees of 47 patients with symptomatic tibiofemoral joint (TFJ) OA and 31 apparently normal knees of 16 volunteers as a control group. Angulation of the ti...

OBJECTIVES To evaluate the functional and radiological results of Schatzker type II fractures treated via subchondral raft screws combined with locking plates. METHODS Twenty-four individuals were enrolled in this study between 2010 and 2014. The depressed joint line was elevated and the defect was filled with allograft. Next, two or three subchondral screws were placed in combination with a ...

In this paper we present an algorithm for estimating the rotation index of a closed regular intersection curve from its singular points. On the basis of this index we have also devised a procedure that guarantees that a closed intersection curve will be traced completely, without overlapping. Combining this procedure with marching steps derived from differential geometric properties has resulte...

The aim of this paper is to analyse the operational costs of the Pu-Shin wholesale ®sh market in Taiwan, using both the activity-based costing (ABC) model and the simulation technique. By using simulation results in the calculated model of ABC, allocated resource costs are more accurate and arbitrary allocation is avoided. The objective of this study is to compute the processing cost per kilogr...
