Medial patellofemoral ligament reconstruction yielded high return-to-sport rate
ORLANDO — Following medial patellofemoral ligament reconstruction, researchers found 70% of patients returned to sport, but less than half returned to pre-injury levels, according to results presented here.
In a retrospective chart review, Jonathan T. Bravman, MD, and colleagues collected SF-12, Norwich Patellar Instability score and Tegner activity level among 44 knees that underwent medial patellofemoral ligament reconstruction. Bravman noted that almost 30% of patients had concomitant tibial tubercle osteotomy. Results showed all patients experienced improvements in the Norwich Patellar Instability Index and SF-12 scores, and there was no recurrence of dislocation.
“As far as the activity levels, we showed that the Tegner increased from preoperative state of nearly two to almost six postoperatively,” Bravman said in his presentation at the Arthroscopy Association of North America Annual Meeting. “However, and what is probably the most significant finding in this paper is that, the postoperative Tegner was lower than the pre-injury Tegner.”
Bravman noted 72% of patients returned to at least one sport, but 40% were able to return to their pre-injury level of sport.
“Those patients had a preoperative significantly higher initial Tegner compared to those who were not able to return,” Bravman said.
He added nearly half of the patients changed their primary sport or activity postoperatively due to lack of interest, fear of re-injury or moving on with other life factors.
“Of the 30% of knees that had a tibial tubercle osteotomy, they had a significantly worse postoperative Tegner compared to those that did not and no associations were found with any graft, be it auto or allograft, or graft-processing type,” Bravman said. – by Casey Tingle
