Beeinflussen Patellahochstand, Patellaventralisation und Patellalateralisation das patellare Schmerzsyndrom nach Implantation von GSB-Totalendoprothesen?

: We examined the degree of retropatellar pain related to biomechanical factors of the implantation in 31 cases of GSB-endoprostheses without retropatellar alloarthroplasty, loosening or infection. Postoperative patella alta and lateralisation of the patella extended the retropatellar pain syndrom but not tibiaventralisation. These results indicate that certain unfavourable patella positions may be responsible for the retropatellar pain syndrom in patients with a GSB-endoprosthesis.
