Aims and objectives
In the literature superolateral part of Hoffa fat pad (SHFP) impingement has been described associated with three of patellar maltracking parameters: patella alta,
increased tibial tubercle-tibial groove(TT-TG) and decreased distance between the posterior part of the patellar tendon and lateral trochlear facet.
However,
the relationship between trochlear dysplasia,
patellar morphology (Wiberg classification) and patellofemoral inclination angle have not been demonstrated statistically significant.
These patients present knee pain that is exacerbated with hyperextension but its importance is controversial because there are asymptomatic people with edema in the SHFP.
In order to establish the importance of edema in SHFP we made the following study.
Our aims and objectives(figure 1) were:
- To determine the variability of different parameters of patellofemoral maltracking in a control group and patients with edema in superolateral part of Hoffa fat pad (SHFP).
- To determine variability of SHFP edema in different MRI of the same patient.
- To compare tibial tubercle-tibial groove distance (TT-TG) and tibial tubercle-posterior cruciate ligament (TT-PCL) values as indicators of patellar instability.
