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.
There is no consensus regarding whether rehabilitation or surgical management is best for the management of a primary patellar dislocation. Consequently this prospective randomized controlled aims to compare the incidence of recurrent knee dislocations and patient reported outcomes of patients with primary patellar dislocations managed with surgery (medial patellofemoral ligament reconstruction) compared to non-operative management (a standardized rehabilitation protocol, control group).
The purpose of this study is to examine the effect of utilizing blood flow restriction (BFR) therapy after distal biceps tendon repair or medial patellofemoral ligament reconstruction (MPFLR) following a tear.
Adult habitual dislocation of the patella is a common dislocation of the patella. The range of lesions is wide and the severity is high. Clinical diagnosis and treatment are difficult. In clinical work, misdiagnosis and treatment are not targeted at pathological mechanisms. This leads to irregular diagnosis and treatment, high failure rate and revision rate, and patients undergoing multiple operations. The project team developed a "four-in-one" surgical technique centered on "tibial tuberosity osteotomy and proximal displacement" in the preliminary research, which overcomes the disadvantages of traditional knee extension surgery and is suitable for adults. Early research Shows safe and effective clinical efficacy. The purpose of this application project is to take independent innovation of core surgical technology as the lead, adopt a two-way cohort study method, compare the clinical efficacy of the new "four-in-one" technology and traditional soft tissue surgery in the treatment of adult habitual patellar dislocation, and analyze and formulate adult habituation Comprehensive and systematic solutions for patella dislocation, relying on this scientific research project to conduct multi-center and large-sample clinical case studies, and evaluate the effectiveness and safety of independent innovative technologies through standardized medical research methods to improve the surgical treatment of adult habitual patella dislocation Success rate, reduce recurrence rate and failure rate, improve the level of clinical treatment of the disease, and finally put forward a special clinical diagnosis and treatment system for the disease in the international academic community.
For severe recurrent patellar dislocation with poor patellar maltracking, derotation osteotomy is an effective clinical treatment. However, derotation osteotomy requires very high requirements for the surgeon. It is necessary to determine the osteotomy surface, control the axis and complete internal fixation in three dimensions. The deviation of the osteotomy surface may cause deformities such as postoperative knee valgus, knee hyperextension, or restricted extension. The hypothesis of this study is to design a 3D osteotomy template for derotation osteotomy with the aid of computer-assisted simulated surgery. Compared with traditional osteotomy, it can effectively improve the treatment effect of recurrent patellar dislocation due to poor patellar maltracking. The incidence of postoperative knee valgus shortens the operation time and reduces the number of intraoperative fluoroscopy. This study intends to adopt a randomized controlled study, and the selection criteria are adolescent patients with recurrent patellar dislocation, aged >14 years, with a positive J sign. The experimental group used mimics 20.0 software to reconstruct the three-dimensional model of the patient based on the full-length images of the lower limbs in the weight-bearing position and the CT of the hip, knee and ankle before the operation. The osteotomy template was designed and 3D printing technology was used to make the osteotomy template for intraoperative osteotomy. The control group used traditional de-rotation techniques. The knee joint range of motion, patella stability, residual rate of J-sign, knee valgus angle, femoral anteversion angle, gait analysis, etc. were compared between the two groups after surgery, and the differences between the two surgical techniques were evaluated
