NCT ID: NCT05763108 Completed - Clinical trials for Recurrent Patellar Dislocation

Clinical Significance and Coexistence of Polymorphisms of Individual Collagen-coding Genes

Start date: April 1, 2022
Phase:
Study type: Observational

The purpose of this study is to assess correlation between recurrent patella dislocation and genetic polymorphism rs1800012 of the COL1A1 Gene and rs12722 of the COL5A1 Gene.

NCT ID: NCT05184439 Completed - Clinical trials for Patellofemoral Osteoarthritis

Evaluation of Adductor Magnus Tenodesis in Patients With Recurrent Patellar Dislocation.

Start date: November 25, 2021
Phase:
Study type: Observational

Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon.The aim of the study is to assess the effectiveness of this surgical procedure in long follow-up. The outcomes will be evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton-Deschamps index, sulcus angle, congruence angle, and patellofemoral angle). This is a continuation of the research published in 2015 with longer follow-up at least 10 years. All available patients will be evaluated with the same protocol, using the same methods and devices. Functional outcome is planned to be measured with scales as above. In radiological assessment Merchant and lateral knee weight bearing view and additionally MRI will be performed. Isokinetic test will be performed in two speeds of 60 and 180 deg/s. Most of important isokinetic parameters such as peak torque, torque in 30 deg, time to peak torque, peak torque to body weight both for quadriceps and hamstrings will be measured and compared to those from former research. Dedicated statistical test will be used for both: analysis of present status and differences from former results.

NCT ID: NCT05119088 Completed - Joint Instability Clinical Trials

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

Start date: January 4, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04838158 Completed - Children, Only Clinical Trials

Assessment of Knee Flexor Muscles Strength in Patients With Patellar Instability

Start date: January 10, 2015
Phase: N/A
Study type: Interventional

The study enrolled 33 patients with confirmed recurrent patellar dislocation, including 6 patients with bilateral involvement. In the study group, both side hamstring muscle were evaluated at the velocities of 60 and 180 deg/s for the following parameters: peak torque, torque in 30 degree of the knee flexion, angle of peak torque and peak torque hamstring to quadriceps ratio (H/Q ratio).

NCT ID: NCT04438109 Completed - Clinical trials for Patellar Instability

Clinical Outcome of the Dynamic Reconstruction of the Medial Patellofemoral Ligament (MPFL)

Start date: April 12, 2019
Phase:
Study type: Observational

In a single surgical center, 213 consecutive patients with 221 knees were surgically treated for recurrent lateral patellar dislocation between 07/2010 and 12/2016. All patients obtained dynamic reconstruction of the MPFL with detachment of the gracilis tendon at the pes anserinus while maintaining the proximal origin at the gracilis muscle. Patellar fixation was performed by oblique transpatellar tunnel transfer and tenodesis screw. Follow-up data including Kujala-, BANFF- and Norwich patellar instability score as well as Return-to-Sport and pain level were collected at a minimum follow-up of 2 years

NCT ID: NCT03983213 Completed - Clinical trials for Patellar Instability

The Comprehensive Assessment in Children After Surgical Treatment of Patellar Recurrent Dislocation.

Start date: May 28, 2019
Phase:
Study type: Observational

The aim of this prospective study is to assess extension apparatus function of the knee based on clinical, radiological, isokinetic and gait analysis data in patients after surgical treatment. There will be used physical examination, Lysholm-Tegner and Kujala scale for clinical assessment. Merchant and lateral X-ray pictures will be analysed for patellar position verification along with isokinetic and gait evaluation to produce conclusions referring to efficacy of the treatment. All subjects included in the study were treated with mpfl reconstruction. Follow-up longer than 2 years in all cases, about 45 patients included.

NCT ID: NCT03798483 Completed - Patella Dislocation Clinical Trials

INDividualised EXercise for Kneecap Dislocations

INDEX-KD
Start date: January 24, 2019
Phase: N/A
Study type: Interventional

This study is a feasibility study. It will assess areas of uncertainty relating to the implementation of an individualised exercise programme for patients with a recent kneecap dislocation. This will help determine if a future larger study is feasible, and inform the design and conduct of future research that would aim to optimise outcomes after a kneecap dislocation.

NCT ID: NCT03304119 Completed - Clinical trials for Patellar Dislocation

Torsion of the Tibial Tuberosity, a New Factor of Patellar Instability?

Start date: April 1, 2016
Phase:
Study type: Observational

Patellar instability (recurrent patellar dislocation) can occur at any age. It is most often seen in young subjects, especially among adolescents. It is commonly accompanied by anatomical factors. A new factor not described in bibliographic sources and characterized by an external torsion of the tibial tuberosity is frequently found in patients with patellar instability thanks to MRIs. This does not seem to be the case when there is no patellar pathology. A statistical study is needed to assess this rotary anomaly. Validate the predictive benefits when measuring the torsion of tibial tuberosity in cases with recurrent patellar dislocation.

NCT ID: NCT03040232 Completed - Clinical trials for Patellar Dislocation

Clinical Outcomes Following Patellar Dislocation in Young Athletes

Start date: January 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02569931 Completed - Clinical trials for Patellar Dislocation

The Unstable Kneecap - the Impact of Anatomy on Function

SPRING
Start date: December 2015
Phase: N/A
Study type: Interventional

The principal objective of the study is to find out which everyday activities make the kneecap unstable in people with patellofemoral instability. Analysing how a patient with an unstable kneecap walks will help us to determine if surgery is successful in these patients by seeing if better scores on patient questionnaires are found in patients following surgery and whether these patients also have a better pattern of walking. The investigators aim to use cameras and pressure pads to see how patients walk before and after surgery and see how this compares to patient scores on the questionnaires. If the investigators find that patients walk better after surgery they can justify that surgery is worthwhile for the patient and cost effective for the NHS.
