PURPOSE OF REVIEW Osgood Schlatter syndrome presents in growing children (boys, 12-15 years; girls, 8-12 years) with local pain, swelling and tenderness over the tibial tuberosity. Symptoms are exacerbated with sporting activities that involve jumping (basketball, volleyball, running) and/or on direct contact (e.g. kneeling). With increased participation of adolescent children in sports, we cri...

Abstract Background Medial patellofemoral ligament reconstruction (MPFLR) is a well-established procedure for addressing recurrent patellar dislocation (RPD) in young patients. However, despite being promising RPD with genu valgum, there scarcity of reports on simultaneous MPFLR and closing-wedge distal femoral osteotomy (CWDFO). The purpose the present study was to observe analyse clinical ima...

Objectives: The tibial tubercle to trochlear groove (TT-TG) distance often guides surgical decision- making for patellar instability. Traditional TT-TG measurements are limited by interrater reliability and lack of consideration variable anatomy throughout flexion. purpose this study was compare the traditional measurement three-dimensional measures generated from automated detection with seque...

Segmentation and computer assisted design tools have the potential to test the validity of simulated surgical procedures, e.g., trochleoplasty. A repeatable measurement method for three dimensional femur models that enables quantification of knee parameters of the distal femur is presented. Fifteen healthy knees are analysed using the method to provide a training set for an artificial neural ne...

A porous-coated, cementless, congruent-contact, three-piece, meniscal-bearing total ankle replacement was developed and used clinically over a 2- to 10-year period for patients with disabling ankle arthritis. Polished titanium-nitride ceramic-coated Ti6Al4V tibial and talar components with a deep-sulcus trochlear groove and two lateral fixation fins for the talar onlay component were used. The ...

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...

Purpose The rotational alignment of the femoral and tibial components is closely related to the results after total knee arthroplasty (TKA). In this study, we measured the combined rotational alignment change (ΔCR) after TKA and compared the different influence of symmetric and asymmetric tibial component designs on the combined rotational alignment. Materials and Methods Eighty-four patients...

BACKGROUND The trochlear groove is the rarest location for osteochondritis dissecans (OCD) of the knee, with only about 50 previously reported cases, most of which were treated before the advent of magnetic resonance imaging (MRI) and modern techniques of cartilage fixation or osteochondral transplantation. The purpose of this multicenter study was to assess the patient presentation and clinica...

Osgood-Schlatter disease (OSD) is a condition in which the patellar tendon insertion on the tibial tuberosity becomes inflamed. It is a well-known condition in late childhood characterized by pain and a bony prominence over the tibial tuberosity. Usually, it resolves at the end stages of skeletal growth. Boys are affected more often than girls, and the age of affection is typically in the secon...
