More than 70% of osteochondritis dissecans (OCD) lesions in the knee joint occur on the posterolateral surface of the medial femoral condyle, designated as the classic area. Approximately 15–20 % of OCD lesions in the knee joint occur in the inferior–central part of the lateral femoral condyle, and 1 % or less occur on the patellofemoral joint surface [1, 2]. We encountered a patient who simult...
background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...
Lateral retinacular release is a useful resource in knee surgery that can be used for disorders of the extensor mechanism. For many years, it was indiscriminately used in the treatment of the various patellofemoral joint alterations, with conflicting functional results. This study aimed to analyze the changes that have occurred in the indications and clinical effectiveness of lateral retinacula...
BACKGROUND The mediopatellar plica is a synovial fold representing an embryonic remnant from the developmental process of the synovial cavity formation in the knee. We aimed to examine the frequency of MRI-detected mediopatellar plica and its cross-sectional association with MRI-detected cartilage damage and bone marrow lesions (BMLs) in the patellofemoral joint (PFJ) in a cohort of subjects wi...
BACKGROUND The intent of the present study was to determine the effectiveness of massage therapy in the rehabilitation of post-anterior cruciate ligament reconstruction patellofemoral pain syndrome. The primary complications following surgical repair of the anterior cruciate ligament-classified as patellofemoral pain syndrome-are hamstring flexion contracture and quadriceps weakness, leading to...
The purpose of this study was to determine if persons with patellofemoral pain (PFP) exhibit differences in patellofemoral joint reaction forces (PFJRFs) during functional activities. Forty females (20 PFP, 20 controls) underwent two phases of data collection: (1) magnetic resonance imaging (MRI) and (2) biomechanical analysis during walking, running, stair ascent, and stair descent. A previous...
[Purpose] For preventing the patellofemoral pain syndrome, this study aims to suggest a proper squat method, which presents selective muscle activity of Vastus Medialis Oblique and muscle activity ratios of Vastus Medialis Oblique/Vastus Lateralis by applying squat that is a representative weight bearing exercise method in various ways depending on the surface conditions and knee bending angles...
Purpose The purpose of this study was to investigate the impact of varying knee flexion and quadriceps activity on patellofemoral indices measured on magnetic resonance imaging (MRI). Materials and Methods MRI of the knee was performed in 20 patients for indications other than patellar or patellofemoral pathology. Axial and sagittal sequences were performed in full extension of the knee with ...
In total knee arthroplasty (TKA), patellofemoral groove design varies greatly and likely has a distinct influence on patellofemoral biomechanics. To analyse the selective influence, five patellofemoral design variations were developed based on Genesis II total knee endoprosthesis (original design, being completely flat, being laterally elevated, being medially elevated, and both sides elevated)...
Between 1999 and 2001 thirty knees underwent a semitendinosus tendon plasty to recreate the medial patellofemoral ligament for recurrent patellar dislocation. The mean follow-up was 38 months. The mean improvement of the patellofemoral congruence angle after surgery was 14 +/- 7 degrees. All patients ended up with a full range of motion, except one patient, whose flexion was limited to 120 degr...
