Lateral Patellar Tilting

The patella lays laterally and a mild tilt can be Figure CS31Lateral subluxation and tilt of the patella caused by tight lateral structures left knee 30 relaxed. Diagnosis is made clinically with pain with compression of the patella and moderate lateral facet tenderness and sunrise knee radiographs will often show patellar tilt in the lateral direction.

Tight retinaculum on the lateral side.

Lateral patellar tilting

. Its also known as patellar instability or kneecap instability. The kneecap is a small protective bone that attaches near the. Repeated lateral pull tests and patellar tilt tests had fair intrarater and poor interrater reliability.

Lateral release is a minimally invasive surgery used to correct an excessive patellar tilt. Normally the lateral border can be passively elevated until the patella is horizontal or un-tilted. The medial retinaculum is not shown in this illustration.

It involves cutting through a tight retinaculum so that the kneecap can slip properly into its groove thereby restoring its normal alignment.

Our results suggest that care must be taken in placing too much emphasis on these tests when making clinical decisions.

If it is tilted the lateral border of the patella lies in a plane posterior to that of the medial border. These tilt angles paradoxically diminish as patellar tilt increases a potential source of confusion. Patellar subluxation is a partial dislocation of the kneecap patella.

The patella has 4 different planes of motion. If a tilted patella cannot be so manipulated the lateral retinaculum. Most tilt angles use the slope of the lateral facet as a measure of tilt.

Flexionextension mediallateral rotation mediallateral patellar tilt and mediallateral patellar shift. Patellar tilt is when the patella is tilted to one side generally the lateral outer side secondary to tightness in the lateral retinaculum the fibrous restraint at the lateral side of the patella. The stability of the patella is dependent on both osseous anatomy and the integrity of longitudinal and transverse soft tissue stabilizers.

In this study we use an MRI tilt angle that increases in the same direction as the actual tilt which is more intuitive. Patellar tracking disorder is the name given to the condition where the patella kneecap isnt moving correctly 1. This misalignment occurs when there is movement at the knee joint ie when your leg is in the process of bending or straightening.

Lateral patellar compression syndrome is the improper tracking of the patella in the trochlear groove generally caused by a tight lateral retinaculum.
