Chronic Patellar Instability

3D printing is emerging as a transformative force spanning across multiple industries. In health care, this cutting-edge technology is revolutionizing the way we evaluate and treat our patients across many disciplines.

In this video, Miho J. Tanaka, MD, PhD, discussed the use of 3D and 4D imaging to better understand the role of trochlear dysplasia for surgical decision-making in patients with patellar instability.

Internal and external rotation of the tibia in relation to the femur may alter tibial tubercle-trochlear groove distance, a key indicator for surgical decision-making in patients with patellar instability, according to results.

Results showed high socioeconomic status, home ownership and full-time employment were predictive of shorter time to evaluation and surgery and improved outcomes for patients undergoing medial patellofemoral ligament reconstruction.

NEW ORLEANS — Medial patellofemoral ligament reconstruction should be the primary treatment for first-time patellar instability in skeletally immature patients, despite historical use of the adductor sling technique, a presenter said.

LAS VEGAS — When assessing patella alta during the management of patellar instability, knee position can influence the measurement of patellar height at the time of radiographs, according to results.

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.

COLORADO SPRINGS, Colo. — Results presented here showed patients who underwent medial patellofemoral ligament repair for patellar instability had a higher failure rate compared with MPFL reconstruction at long-term follow-up.

COLORADO SPRINGS, Colo. — The Sports Medicine Multicenter Research Grant, which reached a “historic” amount of $400,000, has been awarded to Beth E. Shubin Stein, MD, and Shital N. Parikh, MD, for their research on patellar instability.

COLORADO SPRINGS, Colo. — Patients who underwent isolated medial patellofemoral ligament reconstruction maintained outcomes at 5 years with low recurrent instability rates and high return to sport rates, according to results presented here.
