Recurrent Patellar Dislocation | Introduction

Join us on a captivating journey in this Orthopedic Surgery Lecture on Recurrent Patellar Dislocation! We're here to make learning about this knee condition both fun and engaging as we break down its causes, symptoms, and treatments. This interactive video is perfect for medical students, healthcare professionals, and anyone interested in understanding this common knee issue. ▬ 📌 Recurrent Patellar Dislocation Recurrent Patellar Dislocation is a condition where the patella (kneecap) repeatedly dislocates or slips out of its normal position in the trochlear groove of the femur. This can lead to pain, instability, and a decrease in function, and often requires treatment to address the underlying causes and prevent further dislocations. ▬ 📌 Recurrent Patellar Dislocation Etiology Several factors contribute to the development of recurrent patellar dislocations. Anatomical abnormalities such as shallow trochlear groove, high-riding patella (patella alta), and an increased Q-angle (the angle between the quadriceps tendon and the patellar tendon) can predispose an individual to this condition. Ligamentous laxity, muscle imbalances (particularly weak quadriceps or hip muscles), and a history of prior dislocations can also increase the likelihood of recurrent dislocations. ▬ 📌 Recurrent Patellar Dislocation Clinical Features Patients with recurrent patellar dislocations typically present with pain, swelling, and instability of the knee, which may be exacerbated during activities like squatting, climbing stairs, or pivoting. Additionally, patients may report a sensation of their kneecap sliding out of place or giving way during movement. In some cases, individuals may experience recurrent episodes of dislocation or subluxation, leading to further damage to the surrounding structures, such as cartilage and ligaments. ▬ 📌 Recurrent Patellar Dislocation Imaging Proper imaging is essential for diagnosing and evaluating the severity of recurrent patellar dislocations. X-rays can help identify gross anatomical abnormalities, while MRI scans can provide a more detailed view of the soft tissue structures, such as the medial patellofemoral ligament (MPFL) and cartilage. CT scans may be used to assess the alignment of the patellofemoral joint and to plan surgical interventions, if necessary. ▬ 📌 Non-Operative Treatment The primary goals of non-operative treatment are to reduce pain and swelling, improve knee function, and prevent further dislocations. This can be achieved through a combination of physical therapy, bracing, and activity modification. Physical therapy often focuses on strengthening the quadriceps and hip muscles, as well as improving flexibility and balance, to promote proper patellar tracking and stability. Bracing can provide additional support to the knee and help prevent dislocations during the healing process. ▬ 📌 Operative Treatment When conservative treatments fail to provide adequate relief, surgical interventions may be considered. The choice of surgical procedure depends on the specific anatomical issues and the severity of the condition. Lateral retinacular release can be performed to address tight lateral structures, while MPFL reconstruction aims to restore medial support to the patella. Tibial tubercle osteotomy can correct malalignment, and trochleoplasty can address a shallow trochlear groove. ▬ 📌 Patellectomy and Recurrent Subluxation A patellectomy is a rare and aggressive treatment option involving the removal of the patella. It is typically reserved for cases with severe pain, disability, and recurrent subluxation or dislocation that have not responded to other treatments. This procedure can lead to decreased knee function, reduced range of motion, and an increased risk of Knee arthritis, so it should only be considered as a last resort. ▬ 📌 Other Non-Traumatic Dislocations Apart from recurrent patellar dislocations, there are other types of non-traumatic dislocations that can occur in the patellofemoral joint. Habitual dislocations occur when the patella dislocates during specific movements, while congenital dislocations are present at birth due to developmental abnormalities. These conditions might have different etiologies, clinical features, and treatment approaches compared to recurrent patellar dislocations. ▬ 🎬 5500+ sqadia.com Medical Videos ▬▬▬▬▬▬▬▬▬▬ 👩🏻‍⚕️ Accessible Medical Student Education 24/7/365 💡 Simplifying Medical Learning 💪 Study Hard, Dream Big, Achieve More
