In pediatric patients undergoing medial patellofemoral ligament reconstruction and osteochondral fracture fixation procedures, the rate of follow-up surgery was less than 25%, according to findings.

Daniel W. Green, MD, MS, FACS, and colleagues sought to determine the incidence of recurrent instability and second surgery following osteochondral fracture fixation with concomitant medial patellofemoral ligament reconstruction.

“We know that approximately 10% of cases with acute patella dislocation and a relatively significant osteochondral fracture that early surgical stabilization is often necessary,” Green, of the division of pediatric orthopedic surgery at Hospital for Special Surgery in New York, said in his presentation for the American Orthopaedic Society for Sports Medicine Annual Meeting. The meeting was held virtually. “For the past many years, we’ve done this simultaneously with an MPFL reconstruction with an attempt to try and preserve cartilage going forward.”

The researchers analyzed data from a retrospective review of 321 MPFL reconstructions performed by a single surgeon between 2011 and 2019. Of the surgeries performed, 38 knees underwent MPFL reconstruction with osteochondral fixation.

Green and colleagues found patients had an average age of 14.8 years at surgery and average follow-up of 2.1 years. The surgeon used an average of 4.4 biodegradable fixation nails.

The researchers identified that 27 fractures were fixed to the patella, while 10 fractures were fixed to the lateral femoral condyle or trochlea.

Ten patients required a second surgery on the ipsilateral knee, while eight underwent chondroplasty, Green and colleagues wrote. Four patients had removal of biodegradable fixation nails. Two patients had removal of hemi-epiphysiodesis or tibial tubercle osteotomy (TTO) hardware and one patient each had revision MPFL with TTO or lateral meniscus repair.

The one patient who had revision MPFL reconstruction was diagnosed with juvenile idiopathic arthritis and had three additional surgeries, the researchers wrote. Eight patients had a second surgery performed to address cartilage damage or nail removal.

“I think this is a reasonable approach for treating these patients with osteochondral fractures and patella instability,” Green said.
