Patellar Dislocation
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.
Recurrent patellar dislocations may be associated with increased trochlear chondral damage
Published results showed recurrent patellar dislocations were associated with increased incidence and severity of trochlear chondral damage but not patellar chondral damage.
Early rapid rehabilitation may yield positive outcomes for patellar realignment surgery
Compared with conservative rehabilitation, an early rapid rehabilitation protocol may yield improved functional scores and an earlier return to daily activities after patellar realignment surgery, according to published results.
Decreased medial patellar width associated with lateral patellar dislocation
According to published results, decreased medial patellar width may be a more accurate indicator for recurrent lateral patellar dislocation compared with traditional measures such as trochlear dysplasia and patella alta.
Single-leg hop test may predict odds of persistent patellar instability
According to published results, limb symmetry index for baseline single-leg hop for distance and triple hop for distance was significantly associated with persistent patellar instability at 1-year follow-up.
VIDEO: Not all patients with patellar dislocation need more than MPFL reconstruction
NEW ORLEANS — In this video, Beth E. Shubin Stein, MD, discusses when surgeons should perform more than a medial patellofemoral ligament reconstruction in patients with patellar dislocation.
3D-printed models may reveal trochlear variations in patients with patellar dislocation
Results published in the Orthopaedic Journal of Sports Medicine showed 3D reproductions of patellofemoral joint osseous anatomy may reveal trochlear deformities associated with recurrent patellar dislocation.
VIDEO: Understand anatomic factors to address patellofemoral instability, OA
KOLOA, Hawaii — In this video from Orthopedics Today Hawaii, Elizabeth A. Arendt, MD, offered tips and tricks for the management of patellofemoral instability in patients with patellar dislocation and osteoarthritis.
Double-limb graft MPFL reconstruction yielded superior outcomes to single-limb graft
Compared with single-limb grafting, double-limb graft medial patellofemoral ligament reconstruction yielded superior clinical and patient-reported outcomes for the treatment of recurrent patellar dislocation, results showed.
