background: evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative ct scanning. the purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational alig...

INTRODUCTION: A successful surgical outcome in total knee arthroplasty (TKA) depends on multiple factors, including proper rotational and translational alignment of the femoral and tibial components. Small variation in surgical alignment of an implant could potentially have a large impact on knee performance. Several authors have studied the effects of tibial and femoral component’s internal-ex...

BACKGROUND Long term survivorship in total knee arthroplasty is significantly dependant on prosthesis alignment. Our aim was determine which alignment guide was more accurate in positioning of the tibial component in total knee arthroplasty. We also aimed to assess whether there was any difference in short term patient outcome. METHOD A comparison of intramedullary versus extramedullary align...

OBJECTIVES To study the difference in clinical and radiological outcomes between imageless computer-navigated and the conventional technique for performing total knee arthroplasty. DESIGN Prospective case-control study. SETTING University teaching hospital, Hong Kong. PATIENTS Forty-seven patients with imageless computer-navigated total knee arthroplasty were matched with 47 patients with...

BACKGROUND AND PURPOSE Studies have identified factors that contribute to functional limitations in people with knee osteoarthritis (OA), including quadriceps femoris muscle weakness, joint laxity, and reports of knee instability. However, little is known about the relationship among these factors or their relative influence on function. The purpose of this study was to investigate self-reporte...

CONTEXT Knee osteoarthritis (OA) is a leading cause of disability in older persons. Few risk factors for disease progression or functional decline have been identified. Hip-knee-ankle alignment influences load distribution at the knee; varus and valgus alignment increase medial and lateral load, respectively. OBJECTIVE To test the hypotheses that (1) varus alignment increases risk of medial k...

OBJECTIVES Establishing a normative database for anterior plane knee joint alignment in a population is helpful in assessing patients with disorders of the knee joint specially osteoarthritis. Therefore we aimed at establishing the normal alignment in the Sri Lankan adult population using the goniometer which is an inexpensive and simple method of measurement. METHODS A total of 420 healthy a...

OBJECTIVE This study was designed to address a recurring observation in our centre that, despite a satisfactory postoperative radiographic limb alignment, some patients are dissatisfied with the alignment and appearance of their operated leg. We carried out a prospective survey to determine patient perception of limb alignment after total knee arthroplasty (TKA) and whether level of satisfactio...
