Open Lateral Patellar Retinacular Lengthening Versus Open Retinacular Release in Lateral Patellar Hypercompression Syndrome: A Prospective Double-Blinded Comparative Study on Complications and Outcome

Iatrogenic Medial Patellar Instability: An Avoidable Injury

“…13,18,19 This can be a result of excessive severance of the LR with transection of the vastus lateralis tendon (Fig 5) or can result from releasing an LR that was already lax, showing poor patient selection. An isolated LRR should never be performed in the face of trochlear dysplasia, patella alta, or hyperelasticity.…”

Lateral Retinaculum Lengthening or Release

“…Reports of success for isolated LRR/ L are between 14% and 99%. 13 Success was associated with preoperative lateral tightness diagnosed by the glide and tilt tests, 10,13,29 normal Q-angle, 10,30 presence of lateral patellar tilt on imaging examination, 31 and absence of history of lateral patellar dislocation or subluxation, [31][32][33] as well as absence of severe cartilage damage (grade 3-4 cartilage lesions) 33,34 and thus no severe PF arthritis. Poor results were associated with inadequate patient selection and complications.…”

“…7-12 However, with the correct surgical indication, LRR/L has good clinical results. [13][14][15][16][17] …”

Isolierter patellofemoraler Gelenkersatz

“…Somit Abb. 8 Hinblick auf Schmerzauslöschung und Quadrizepsatrophie ist [28]. Bei fortschreitender lateral akzentuierter patellofemoraler Arthrose kommt die laterale Facettenresektion zum Einsatz.…”
