BACKGROUND The contribution of lower limb rotational malalignment to patellofemoral pain and instability has been well recognized. The purpose of the present study is to review the role of computed tomography (CT) and magnetic resonance imaging (MRI) in assessment of abnormal rotational alignment of lower limb. EVIDENCE ACQUISITION An analysis of all available literature in the English langua...

Introduction: Distal Femoral fracture may lead to the development of post-traumatic arthrosis knee joint because direct intraarticular injury. Malunion distal femur fracture, intra-articular osseous defects, limb malalignment and compromised surrounding soft tissues in turn affect outcome total arthroplasty (TKA) makes it a technically demanding surgery. Here we report our experience regarding ...

Objective The study aimed to investigate whether there is any association of anterior knee pain and knee function with chondromalacia stage and patellofemoral alignment in patients with anterior knee pain for over a month and with chondromalacia patellae (CMP) detected by magnetic resonance imaging (MRI). Materials and Methods We reviewed the medical records of 38 patients who underwent a kne...

BACKGROUND While matrix-induced autologous chondrocyte implantation (MACI) has demonstrated encouraging outcomes in the treatment of knee chondral defects, there remains little available research specifically investigating its use in the patellofemoral joint. PURPOSE To prospectively evaluate the clinical and radiologic outcome of MACI in the patellofemoral joint. STUDY DESIGN Case series; ...

Dorsal defect of the patella (DDP) is an uncommon but well-documented disease entity. We report a case of bilateral DDP with patellar hypoplasia and patello-femoral malalignment. Detailed imaging features including radiographic, magnetic resonance imaging, and computed arthrotomographic appearances, are described.

Objectives: Knee osteoarthritis (OA) is a common degenerative or post-traumatic condition, and may affect one more compartments, including the medial lateral tibiofemoral patellofemoral articulations. Isolated (PFOA) has been reported in 24% of women 11% men aged > 55 years presenting for evaluation knee pain. PFOA result abnormal mechanical loading across joint, often related to prior insta...

OBJECTIVES To examine the size and direction of osteophyte in knee osteoarthritis (OA) and to determine associations between osteophyte size and other radiographic features. METHODS Knee radiographs (standing extended anteroposterior and 30 degrees flexion skyline views) were examined from 204 patients referred to hospital with symptomatic knee OA (155 women, 49 men; mean age 70, range 34-91 ...

BACKGROUND Isolated chondral lesions of the patella are particularly challenging to treat, and long-term studies of treated isolated patellar lesions are limited. Previous short-term studies have reported favorable outcomes of autologous chondrocyte implantation (ACI) of the patella and/or trochlea, with a trend toward improvement when anteromedialization (AMZ) of the tibial tubercle was perfor...
