Abstract
Introduction & Objectives:
Medial Patellofemoral ligament (MPFL) reconstruction serves as the primary procedure to restore patellar stability and prevent further dislocation. Many different techniques have been used for the reconstruction of MPFL, but there is no consensus regarding the choice of technique and graft used. This study presents another technique for MPFL reconstruction using a minimal invasive technique de novo and arthroscopic guided to harvest quadriceps tendon (QT) graft without the use of a harvesting tool.
Case Report:
A 37-year-old female presented to the emergency room with the chief complaints of left knee pain and swelling following the third spontaneous dislocation of the patella. The patient had a few episodes of locking sensation and instability of the left knee while walking, especially while climbing stairs. A knee MRI revealed MPFL tear in the left knee. A modified minimal invasive MPFL reconstruction technique was performed.
Result & Discussion:
MPFL reconstruction using quadriceps tendons has shown great outcomes, although it is highly invasive to harvest the graft. A minimally invasive procedure for harvesting quadriceps tendons requires specialized instrumentation. The IKDC, Lysholm, and Modified Cincinnati scores improved significantly from preoperatively 48.3%, 49%, and 51% to 89.7%, 90%, and 95% consecutively. No recurrent patellar dislocations or swelling were reported during follow-up. This study performed a minimally invasive procedure without using specialized instrumentation and the outcome of this procedure is excellent.
Conclusion:
MPFL reconstruction using superficial quadriceps tendon autograft can be done with a minimally invasive technique without the use of specialized instrumentation and has shown excellent knee functional improvement
