Filter by:This study aims to determine the ability of medial patellofemoral ligament (MPFL) repair augmented with Biobrace® to decrease the re-dislocation rate after a primary patellofemoral dislocation. First-time patellofemoral dislocation is a significant problem, and the ramifications of recurrence for patients are substantial. Due to the multifactorial nature of the pathoanatomy of patellofemoral instability, it has been difficult to design trials that will show how interventions could affect the natural history of these young patients. No definitive studies have determined whether the surgical reconstruction of the MPFL in patients with mild to moderate pathoanatomic risk factors will decrease the re-dislocation rate after a first-time dislocation. In addition, to date, no synthetic option has provided both biology and strength for ligament augmentation. This innovation may allow for a minimalist approach to keeping the patella centred in the trochlear groove during the healing phase after a first-time dislocation.
The aim of this study is to investigate the role of tibial tubercle osteotomy (TTO) on the subjective and objective outcomes following medial patellofemoral ligament reconstruction (MPFL-R) in patients with an increased tibial tubercle-trochlear groove (TT-TG) distance with or without patella alta. This Pilot RCT will assess the feasibility of conducting this study for: 1. The ability to recruit study patients 2. Adherence to the study protocol 3. Completion rates of patient follow-up at a minimum of 12 months post-operative
The objective of the present study will be to evaluate the clinical patellofemoral joint function (primary endpoint) and radiographically the patellofemoral arthritic degeneration (secondary endpoint) of of MPFL reconstruction with fascia lata allograft at a minimum follow-up of 2, 5 and 10 years in a group of 25 patients.
The objective of the present study is to compare the stability and alignment of the patella in patients with previous recurrent dislocation treated with medial patellar femoral ligament reconstruction with fascia lata allograft, 5 years after surgery by conventional CT and by CT under weight-bearing. Conventional CT will be performed with the patient supine, the knee fully extended and with the muscles of the thigh and leg completely relaxed. On the same day, the patient will undergo a CT scan of the knee under weight-bearing with the Cone Beam Computed Tomography (CBCT) scanner system. The CT images will be viewed through the PACS system by two independently expert radiologists who will measure the tilt, congruence angles and the TT-TG with the methodical notes described in the literature. The use of a CT under weight-bearing allows for the first time to evaluate in a realistic way the stability and tracking of the patella, with the knee flexed and therefore with the activation of the quadriceps muscle.
