Lateral patellar Hyperpressure

PURPOSE OF THE STUDY The study retrospectively reviews the outcomes of patella stabilisation surgeries performed at our department in the period 2010-2020. It aimed to provide a more thorough evaluation, to compare the respective types of MPFL reconstruction and to confirm the beneficial effect of tibial tubercle ventromedialization on patella height. MATERIAL AND METHODS In the period 2010-2020, a total of 72 stabilisation surgeries of patellofemoral joint in 60 patients with objective patellar instability (OPI) were performed at our department...

Patellofemoral cartilage degeneration is usually associated with a tight lateral retinaculum (lateral hyperpressure). The position of the patella on the femoral groove under hyperpressure makes reasonable access to the cartilage defects difficult for the arthroscopist. Frequently, the surgeon can barely see the cartilage, and the problem cannot be satisfactorily managed. By performing a lateral release and tilting the patella with a laterally drilled Kirschner wire, the articular surface of the patella can be completely exposed, allowing even perpendicular holes to be drilled whenever necessary...

Some chondromalacia are caused by an hyperpressure on the lateral articular facet of the patella. The authors describe the clinical signs and the radiological findings in this condition. It is due to a retraction of the lateral patellar ligament. They have operated on 133 cases and reviewed 115 knees. After a simple section of the lateral patellar ligament, results were satisfactory in 80 percent of the cases. Biopsies of the malacic cartilage were performed and pathological changes were described.
