In PFPS, the clinical symptoms are diffuse peripatellar and retropatellar localized pain with prolonged knee flexion and crepitation during weight-bearing activities such as sguatting, running or going up and down stairs.
Currently, exercise programs have been used mostly in the treatment of PFPS as a non-operative technique.
This study was planned to reveal whether patellar bracing is of benefit in reducing pain and increasing functional capacity in patients with PFPS.
Subjects: Potential subjects were men or women aged 18-40 years with a history of PFPS
lasting at least 6 months.
Conclusion: There is significant weakness of the hip abductor and external rotator muscles, but no alteration in lower extremity kinematics in subjects with PFPS.
PFPS is a common musculoskeletal disorder encountered by physiotherapists, yet its aetiology remains contentious and treatment of this complaint is often challenging.
A suggested reason for the lack of association was that the stair descent task may not have been challenging enough, meaning that the subjects with PFPS were able to maintain lower limb alignment.
Patients who overpronate are more likely to have PFPS than are those whose stride is even.
Rehab for PFPS includes improving flexibility in the hamstrings, iliotibial band, and lateral retinaculum.
Consequently, the best treatment for PFPS includes physical therapy, with a focus on strengthening exercises for the outside of the quadriceps muscle (with an attempted focus on the vastus medialis oblique).
Despite its prevalence, there is no clear consensus in the literature regarding terminology, the aetiology or treatment for PFPS (Thomee, Augustsson & Karlsson, 1999).
There have been numerous theories proposed as the cause of PFPS, such as malalignment of the lower extremity (Thomee et al, 1999), excessive foot pronation, muscle imbalance, quadriceps insufficiency (Brody & Thein, 1998), and patellar incongruence (Gigante, Pasquenelli, Pallidini, Ulisse & Greco, 2001).
