OBJECTIVE To use forward dynamic simulations of forward and backward pedaling in order to determine whether backward pedaling offers theoretical advantages over forward pedaling to rehabilitate common knee disorders.DESIGN. A comparison of knee joint loads was performed during forward and backward pedaling.BACKGROUND. Pedaling has been shown to be an effective rehabilitation exercise for a vari...

patellofemoral pain syndrome (pfps) is the most common overuse syndrome in athletes. it is one of the causes of anterior knee pain in athletic population who come to the sports medicine clinic. patellofemoral pain is more common among female athletes especially adolescents and young adults. symptoms include: persistent pain behind the patella or peripatella. pain increases on ascending and desc...

INTRODUCTION Iatrogenic patellar fracture is reported as a complication of patella procedures, such as medial patellofemoral ligament reconstruction, reconstruction of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and resurfacing the patella in total knee arthroplasty. CASE PRESENTATION A 65-year-old lady with right patella fracture was treated with ope...

The principles of rehabilitation after medial patellofemoral ligament reconstruction are similar to those guiding rehabilitation after other ligamentous reconstructions of the knee, such as anterior cruciate ligament (ACL). The key features are to address pain control, range of motion (ROM), quadriceps strengthening, and proximal lower limb control. Return of full ROM, pain control, and protect...

In order to reconstruct the medial knee to restore the original biomechanical function of its ligamentous structures, a thorough understanding of its anatomic placement and relationship with surrounding structures is required. To restore the knee to normal kinematics, the diagnosis and surgical approach have to be aligned, to successfully reconstruct the area of injury. Three important ligament...

BACKGROUND Medial patellofemoral ligament (MPFL) reconstruction has become one of the most common and widely used procedures to regain stability among patients with recurrent lateral patellar dislocation. While recent studies demonstrated low recurrence rates, improved patient-reported outcome measures, and a high rate of return to sports, limited literature explored its effectiveness as an iso...

INTRODUCTION Chronic patellofemoral instability occurs mainly in adolescent females and can also be induced by medial patellofemoral ligament (MPFL) injury. There are no case reports of MPFL reconstruction for chronic patellofemoral instability due to MPFL injury in aged populations. CASE PRESENTATION 81-year-old female presented with left knee pain, giving way, and patellar instability while...
