AI Article Synopsis
- The study aimed to assess the effectiveness of arthroscopic surgery for recurrent patellar dislocation through the reconstruction of the medial patellofemoral ligament.
- 25 patients (10 males and 15 females, average age 18.4) with a history of recurrent dislocation underwent the procedure, resulting in significant improvements in knee function and pain relief.
- Post-surgery, there were no complications, and patient assessments showed marked increases in knee range of motion and improved scores on clinical evaluation tools, indicating that the surgical method was both safe and effective.
Article Abstract
Objective: To observe the therapeutic effects of arthroscopic treatment for recurrent patellar dislocation by anatomical reconstruction of medial patellarfemoral ligament.
Methods: From June 2009 to December 2014, 25 patients with recurrent patellar dislocation were treated with anatomical reconstruction of medial patellarfemoral ligament surgery under arthroscopy. There were 10 males and 15 females, with an average age of 18.4 years old (ranged, 15 to 25 years old ). There were 15 patients who had a medical history of sports injury, 7 patients had a chronic impairment history, and the other 3 patients had the symptoms without obvious predisposing causes. Fourteen patients had injuries on the right knee and 11 patients had injuries on the left knee. All the patients suffered from patellar dislocation 3 to 10 times. After operation, the exercise of knee joint were performed postoperatively. The knee range of motion, Lysholm score, Kujala score, Insall criteria, Patellar apprehension test and patellar grinding test were observed to evaluate the clinical effects.
Results: All the patients were followed up, and the duration ranged from 12 to 48 months, with an average of 24.8 months. After surgery, all the wounds were healed excellent and there were no complications like surgical incision infection or patellar redislocation. The ranges of motion was increased from preoperative (105.40±5.93)° to postoperative(122.60±5.42)°. At the latest follow-up, the Lysholm scores were increased from preoperative 64.12±7.49 to postoperative 91.44±5.53, the Kujala scores were increased from preoperative 57.88±5.10 to postoperative 92.44±2.69. According to the Insall criteria, 19 patients got an excellent result, 5 good and 1 fair.
Conclusions: It has a satisfactory clinical therapeutic effect on anatomical reconstruction of medial patellarfemoral ligament under arthroscopy for the treatment of recurrent patellar dislocation. It is helpful for the relief of clinical symptoms and improvement of knee joint function.

Objectives: To propose a reliable and standard 3D assessment method to analyze the effect of weight-bearing (WB) status on the location of patella and clarify the diagnostic performance of 3D parameters for recurrent patellar dislocation (RPD) in WB and non-weight-bearing (NWB) conditions.
Methods: Sixty-five knees of RPD patients and 99 knees of controls were included. Eight landmarks, two lines and a coordinate system were defined on 3D bone models of knees based on weight-bearing CT and non-weight-bearing CT.

Background: Studies have revealed abnormalities of the epiphyseal plate of the distal femur in patients with trochlear dysplasia, but it is unclear whether the epiphyseal plate could be remodeled after surgical correction of patellar dislocation.
Purpose: To investigate whether the morphology of the epiphyseal plate and trochlea could be improved after medial patellar retinaculum plasty in skeletally immature patients and to investigate the correlations between the morphology of the epiphyseal plate and trochlear dysplasia as well as clinical outcomes.
Study Design: Cohort study; Level of evidence, 3.

Background: Radiological measurements can predict patellar dislocation and are used to plan patella-stabilizing surgery in patients who have patellofemoral instability. However, it is unclear whether these measurements can predict subjective symptoms in patients without previous stabilizing surgery.
