Proximal Medial Patella Restraint Reconstruction: Medial Patellofemoral Ligament and Medial Quadriceps Tendon-Femoral Ligament Reconstruction.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The proximal medial patella restraints (PMPR) are comprised of the medial patellofemoral ligament (MPFL) and the medial quadriceps tendon femoral ligament (MQTFL) and serve as the principal patellar stabilizers in early to mid-flexion of the knee. Indications: PMPR reconstruction is an ideal stabilization technique for recurrent patellar instability or after a first-time dislocation associated with an osteochondral fracture requiring surgical treatment. Technique Description: A single 3 to 4 cm longitudinal incision is made at the midpoint between the medial patella and medial epicondyle. A single hamstring allograft is used. This graft is passed through a slit in the medial aspect of the quadriceps tendon deep to the vastus medialis toward the origin on the femur to create the MQTFL limb. The remaining MPFL limb is anchored to its inferior insertion site on the patella, then laid into a trough along the medial patella. The 2 limbs are then passed through a femoral socket and anchored with a PEEK tenodesis screw at 45° of flexion. Results: The patient's patellar stability was markedly improved with normal physiologic translation, and she was able to return to competitive softball without further dislocation events. Studies evaluating similar combined MPFL/MQTFL reconstructions have reported improvements in recurrent instability. Discussion/Conclusion: This technique for PMPR reconstruction may provide more anatomic and physiologic medial patellar stabilization in cases of patellar instability without increasing time, cost, or complexity of the procedure or recovery.
