Outcome measures
Primary outcome
The primary outcome is cartilage status determined on MRI and expressed by a
semiquantative score for knee osteoarthritis (MOAKS score).
Secondary outcome
Secondary outcomes are clinical and radiological outcome in terms of pain and
functioning measured by patient reported outcome measurements and
patellofemoral osteoarthritis measured on conventional X-rays.
Background summary
Trochlear dysplasia is the most consistent anatomic factor present in patients
with recurrent patellar dislocations. Due to the change in the trochlea during
the trochleoplasty the patellofemoral joint is modified and consequently the
joint kinematics change. This might lead to the development of early
patellofemoral osteoarthritis. It is unknown how pain develops in the long-term
after a trochleoplasty and if the pain is related to radiological outcomes.
Radiological follow-up using MRI and clinical evaluation will provide data to
evaluate the effects of this procedure on patellofemoral OA and pain ten years
postoperatively.
Study objective
To evaluate the radiological and clinical outcomes 10 years after a
trochleoplasty. We are especially interested in the cartilage status and
patellofemoral pain of the patients.
Study design
Cohort study, describing the ten year follow-up of a consecutive case series of
patients who underwent a trochleoplasty.
Study burden and risks
The patients are invited to visit the Sint Maartschliniek once. The additional
time the patient invests in the research is approximately 2 hours. Prior to the
examination, the patient is asked to fill out the questionnaires. During the
visit, X-rays and an MRI are made. In addition, a physical examination will be
conducted. The questionnaires and physical examination will not be additional
to the patient. The total amount of radiation of the X-rays is 0.01 mSv and
falls within the limit of the International Commission of Radiological
Protection.
