Knee Function in Patients With Two or More Episodes of Patella Dislocations

Joint Instability

Patients aged 12 - 30 years, with recurrent patella dislocations, are consecutively included into a randomized prospective study. This study comparess the outcome of two forms of treatment for recurrent patella dislocation. One group is offered reconstruction of the medial patellofemoral ligament (MPFL), the second group is offered a standardized training program.

Outcome After Soft Tissue Realignment of the Tibial Insertion of the Patella Tendon

Patella Dislocation

Soft tissue realignment of the tibial insertion of the patella tendon is a simple operative technique for treating dislocation of the patella in childhood and adolescence. It is performed in children with either recurrent dislocation or complicated primary dislocation in cases with malalignment or maltracking of the patella and a lateralised tibial tuberosity. It can be performed in patients with open epiphyses. We investigate long-term outcome after this procedure.

The Impact of Tibial Tubercle-trochlear Groove Distance and Patellar Height on the Outcome of Isolated...

Patellar Dislocation

The investigators plan to perform a prospective observational cohort study of patients undergoing MPFL reconstruction for the treatment of episodic patellar instability in the absence of significant degenerative disease. The investigators will follow these study subjects for a minimum of two years to monitor their functional and clinical outcome.

Clinical Outcomes Following Patellar Dislocation in Young Athletes

Patella Dislocation RecurrentPatellar Dislocation

The purpose of this study is to identify predictors of future injury and disability following LPD. The investigators' long term goal is to improve longitudinal outcomes of athletes with LPD following surgical and non-surgical management. Currently, there is limited information available to clinicians regarding appropriate criteria for returning athletes to sports participation following LPD. The evidence produced by this study will provide necessary information to develop appropriate rehabilitation strategies that may reduce the risk for future patellar instability and associated patellofemoral joint dysfunction and pain.

PROMs and Patellar Tracking After Isolated MPFL Reconstruction.

Patellar DislocationPatellar Dislocation2 more

Patellar dislocations cause pain and functional decline in adolescents, which can be restored by a MPFL reconstruction. Yet, many reconstruction methods are being used clinically as consensus on the ideal MPFL reconstruction method is lacking. We propose a soft-tissue loop reconstruction method which potentially decreases the risk for of iatrogenic fracture of the patella and prevents femoral tunnel malposition.

Development of a Test Battery for Measurement of Knee Function in Patients With Patellar Instability...

PatellaJoint Instability1 more

About six months after patella stabilizing surgery postoperative restrictions are commonly lifted and patients may consider whether a return to activity/sports is feasible. Currently, there are no evidence-based criteria to determine a patients readiness for sports and/or activity (RTS) following stabilizing surgery. The purpose of this project was therefore to investigate the feasibility of a test battery to evaluate knee function in postoperative follow-up evaluation - and in RTS decisions - for patients with patellar instability. Banff Patellofemoral Instability Instrument 2.0 and Norwich Patellar Instability Score is being translated and validatend in a Norwegian population. Furter is patients experience of living with patellar instability explored.

The Clinical Results of Derotational Osteotomy Based on 3D Osteotomy Template for Treatment of Recurrent...

Recurrent Patellar DislocationOsteotomy1 more

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
