BACKGROUND Meniscus allograft transplantation (MAT) has shown efficacy in relieving pain and improving knee joint function, but objective evaluation in a large number of patients is necessary to verify this effect. HYPOTHESIS Meniscus allograft transplantation relieves pain and improves function of the involved knee joint. Objective evaluation provides(More)
BACKGROUND In lateral meniscus allograft transplantation (MAT) using the keyhole method, precise trough drilling is critical for ensuring the graft is placed at the correct anatomic position to minimize the risk of extrusion. However, no study has focused on the effect of bony trough axial obliquity on graft extrusion. Our purpose was to investigate whether(More)
BACKGROUND Little is known about morphologic changes in the remodeling period after human meniscal allograft transplantation (MAT). HYPOTHESIS The gross structure of meniscal transplants may be altered significantly in width and thickness during early remodeling periods. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Thirty-one patients who(More)
The aim of this study was to determine (1) variations in the shape of the proximal, middle, and distal femur in a series of Korean patients who had undergone total knee arthroplasty (TKA), (2) the preoperative relationship between these three parameters and the distal valgus cutting angle referenced off the femoral intramedullary guide, and (3) whether(More)
Severe varus deformity may lead to premature failure of total knee arthroplasties (TKAs) because of technical difficulties associated with satisfactory alignment and good ligament balance. The aim of the study was to assess whether preoperative varus severity would affect the longevity, clinical outcomes, and complication rates of TKAs. From a prospectively(More)
High-flexion knee prosthesis designs are generally thought to be of benefit only in patients with a satisfactory preoperative flexion angle. The aim of the study was to evaluate whether high-flexion designs were indeed worthless in osteoarthritis patients with severe preoperative flexion limitation. The postoperative maximum flexion was compared in(More)
Plain radiographs are frequently used to select appropriately sized meniscal allografts, of which the width and length cannot be always perfectly matched. The objective of this study was to decide which of these dimensions should be matched with a more priority considering proper position of the lateral meniscal transplants. The positions of 34 lateral,(More)
The purpose of this study was to determine the effect of a radial tear on degenerative medial meniscus posterior horn tear extrusion and to identify predictors of medial meniscus extrusion. We reviewed the records of 102 knees with medial meniscus posterior horn tears and degeneration that underwent a partial meniscectomy. Tears were classified as root (n =(More)
With recognition of the biomechanical role of the meniscus, such as load distribution and joint stability in the knee joint, there has been a shift in the treatment of meniscal tears from open total meniscectomy to preservation of the meniscal functions as much as possible with symptomatic relief. Recently, technical development of meniscal surgery, with(More)
BACKGROUND Two previous studies recently raised the possibility of a high risk of early femoral components loosening with high-flexion (HF) prostheses in Asian populations and suggested that the high failure rate of HF TKAs was associated with HF ability. However, these findings are controversial given other studies reporting a low incidence of aseptic(More)
