ARTICLE HIGHLIGHTS
Research background
The patellofemoral joint stability is aided by the medial patellofemoral ligament (MPFL), along with the medial patellotibial ligament (MPTL) and medial patellomeniscal ligament (MPML). While the MPFL is the primary stabilizer, the MPTL plays a critical role as a secondary limiter. However, there are limited studies on the combined reconstruction of MPFL and MPTL and its advantages.
Research motivation
Different studies on the results of patellar instability management are published with no certain consensus. So, it was necessary to do an analysis to clarify the role of combined reconstruction of MPFL and MPTL in patellar instability management.
Research objectives
To find out the efficacy of combined reconstruction of MPFL and MPTL.
Research methods
Several databases were searched to obtain eligible randomized controlled trials. Outcomes were mechanical ventilation time, length of intensive care unit stay, and duration of postoperative hospitalization.
Research results
Combined MPFL and MPTL reconstruction led to positive outcomes in Kujala scores at 12 and 24-mo follow-ups. The surgeries reduced pain, but the trend of pain reduction decreased over time according to cumulative meta-analysis.
Research conclusions
Combined MPFL and MPTL reconstruction is a safe method with favorable clinical results in patellar dislocation and instability.
Research perspectives
Our conclusion needs further confirmation through the conduct of additional high-quality studies.
