Patellofemoral Update
Preexisting patellar tendinopathy did not affect ACL reconstruction results with autograft
SAN DIEGO — Mild to moderate preoperative patellar tendinopathy may not significantly affect postoperative outcomes of ACL reconstructions with a bone-patellar tendon-bone autograft, according to results presented here.
Patellar tracking, measurements may predict pediatric patellar osteochondritis dissecans
Published results showed increased tibial tubercle–trochlear groove distance and increased cartilaginous and bony sulcus angles were associated with patellar osteochondritis dissecans in pediatric patients.
BLOG: 3D patellofemoral joint imaging provides new path for better surgical planning
Optimizing surgical intervention for a patient with recurrent patella instability can be challenging, particularly when considering the possibility of adding an osteotomy. Accuracy is paramount.
Medial patellofemoral complex reconstruction may be warranted for first-time dislocation
Results showed combined medial patellofemoral ligament and medial quadriceps tendon femoral ligament reconstruction may yield improved outcomes for skeletally immature patients with first-time dislocations vs. nonoperative treatment.
Thin flap trochleoplasty augments MPFL reconstruction for recurrent patellar instability
Published results showed medial patellofemoral ligament reconstruction combined with thin flap trochleoplasty may yield low rates of redislocation and reoperation for patients with high-grade trochlear dysplasia and recurrent instability.
High-volume surgeons linked with lower revision rates after patellofemoral arthroplasty
Published results showed high-volume surgeons who performed more than five patellofemoral arthroplasty procedures per year had decreased rates of revision compared with low-volume surgeons.
Robotic-assisted MPFL reconstruction may yield improved outcomes vs. freehand technique
According to published results, robotic-assisted medial patellofemoral ligament reconstruction yielded more accurate femoral tunnel positioning, increased functional scores and less radiation exposure compared with a freehand technique.
Tibial tubercle transfer associated with low complication risk with, without distalization
Results published in the American Journal of Sports Medicine showed tibial tubercle osteotomy with vs. without distalization yielded similar postoperative outcomes for patients with patellofemoral instability, malalignment and patella alta.
Trochlear bump, patella alta may predict recurrent instability after MPFL reconstruction
According to published results, patients with dysplasia with a trochlear bump and patella alta may be at increased risk for recurrent instability after medial patellofemoral ligament reconstruction.
Instrument may assess kinesiophobia, outcomes in patients with patellofemoral instability
Results showed significant correlation between patient-reported outcome measures for patients with patellofemoral instability and the Banff Patellofemoral Instability Instrument 2.0, which may assess kinesiophobia and pain catastrophizing.
