Summary
This study shows that an improved arthroscopic procedure for acute patellar dislocation is a minimally invasive treatment with satisfactory short-term clinical outcomes. The technique demonstrated significant improvements in patient-reported scores and a high rate of excellent or good results without recurrence.
Area of Science:
- Orthopedic Surgery
- Arthroscopy
- Sports Medicine
Background:
- Acute patellar dislocation is a common knee injury.
- Arthroscopic techniques offer minimally invasive treatment options.
- Evaluating improved surgical procedures is crucial for optimizing patient outcomes.
Purpose of the Study:
- To assess an enhanced arthroscopic surgical technique for acute patellar dislocation.
- To evaluate the clinical results and efficacy of this minimally invasive procedure.
Main Methods:
- A cohort of 22 patients (25 knees) with acute patellar dislocation underwent an improved arthroscopic procedure.
- The technique involved lateral retinaculum release and medial capsule/retinaculum repair.
- Clinical outcomes were assessed using Lysholm score, Visual Analogue Scale (VAS), and the Insall scale.
Main Results:
- No recurrence of patellar dislocation was observed during an average 17-month follow-up.
- Significant improvements were noted in Lysholm scores (67.3 to 96.6) and VAS scores (6.5 to 1.8).
- The Insall scale showed excellent results in 18 knees and good results in 5 knees (92% excellent/good rate).
Conclusions:
- The improved arthroscopic procedure for acute patellar dislocation is minimally invasive.
- This technique yields satisfactory short-term clinical outcomes.
- The procedure demonstrates a high success rate and low recurrence in managing acute patellar dislocations.
