Background Patellar height has long been considered a risk factor for patellofemoral instability. However, recent pediatric literature demonstrated a reduction in patellar height measurements following medial patellofemoral ligament (MPFL) reconstruction. Purpose To assess the mean change in patellar height and the percentage of skeletally mature patients with patellar height ratios reduced t...

BACKGROUND Whilst patellofemoral pain is one of the most common musculoskeletal disorders presenting to orthopaedic clinics, sports clinics, and general practices, factors contributing to its development in the absence of a defined arthropathy, such as osteoarthritis (OA), are unclear.The aim of this cross-sectional study was to describe the relationships between parameters of patellofemoral ge...

BACKGROUND High tibial osteotomy (HTO) is a well established technique for the treatment of medial osteoarthritis of the knee with varus malalignment. Results of total knee arthroplasty (TKA) after previous HTO are still discussed controversially. The aim of this study was to elucidate the clinical and radiological results as well as perioperative data of prior HTO on TKA. METHODS Forty-one T...

OBJECTIVE To analyze occurrences of trochlear dysplasia in patients with Down syndrome in the presence and absence of femoropatellar instability. METHODS Eleven knees with stable patellae and thirteen with unstable patellae in patients with Down syndrome were compared. Radiographs were produced to evaluate patellar height, trochlear angle and femoropatellar congruence angle. RESULTS The pre...

OBJECTIVES The aim of this study is to evaluate the efficacy of the central (transpatellar tendon) portal technique for the treatment of isolated medial bucket-handle type meniscal tears with the arthroscopic menisectomy procedure. PATIENTS AND METHODS In this study, fifty patients with isolated medial bucket-handle type meniscal tears were evaluated. They were divided into two groups with 25...

Open-wedge high tibial osteotomy (HTO) is an established technique for the treatment of symptomatic varus malaligned knees. In this study, we prospectively followed up 13 patients (14 knees) who underwent navigation system-supported HTO for varus knee deformity. Preoperatively all patients underwent a physical examination, and anteroposterior and laterolateral lower limb weight-bearing digital ...

A lowering of the patella after total knee arthroplasty is accompanied by pain and a restriction of the range of motion. With its etiology being unclear at present, a multifactorial genesis is under discussion. For the first time, we present a case report describing an HIV infection as a possible cause of patella infera.A 54-year-old HIV-positive woman developed patella infera (Insall-Salvati r...

Aim: This study aims to investigate the length, width and thickness of patellar tendon type length patella with MRI reveal normal values ​​of morphology specific Turkish population.
 Material Method: The was conducted 348 individuals (137 males, 211 females) who applied our hospital, had no anterior knee pathology, MRIs. proximal distal tendon, type, prepatellar infrapatellar fat pad signa...

We investigated the clinical outcome of a reconstructive procedure of the medial patellofemoral ligament for the treatment of habitual or recurrent dislocation of the patella in four children (6 knees), with a minimum follow-up of four years. The technique involves transfer of the tendon of semitendinosus to the patella using the posterior one-third of the femoral insertion of the medial collat...
