Purpose To analyze postoperative physical and sexual activity as well as Quality of Life (QoL) after complex patellofemoral reconstructions in female patients suffering from chronic patellofemoral instability (PFI). Methods Female patients aged > 18 years undergoing complex patellofemoral reconstruction for chronic PFI were included. Complex patellofemoral reconstruction was defined as medial patellofemoral ligament reconstruction (MPFL‐R) combined with at least one major bony procedure (distal femoral osteotomy, high tibial osteotomy, and trochleoplasty). Outcome was evaluated retrospectively after a minimum follow‐up of 12 months using Tegner activity scale, Banff Patellofemoral Instability Instrument 2.0 (BPII 2.0), EuroQol‐5D‐3L (EQ‐5D‐3L), EuroQol Visual analog scale (EQ‐VAS), and a questionnaire about sexual activity. Results A total of 34 females (mean age, 26 ± 5 years) with a mean follow‐up of 45 ± 16 months were included. Seventy‐seven percent had one major bony correction + MPFL‐R and 24% had at least two major bony corrections + MPFL‐R. The re‐dislocation rate was 6%. Median Tegner activity scale improved from 3 (range 0–10) to 4 (range 2–6) (n.s.) and an improved activity level was observed in 49% of subjects. QoL scores showed an EQ‐5D‐3L Index Value of 0.89 ± 0.15, EQ‐VAS of 80.3 ± 11.4, and BPII of 68.3 ± 19.1. Thirty‐four percent of patients reported restrictions of sexual activities due to PFI preoperatively with an improved sexual function observed in 60% postoperatively due to less pain, improved mobility, and less apprehension. Postoperative return to sexual activity was 91%, whereof 19% reported current restrictions of sexual function because of pain and/or limited range of motion. Conclusion Despite the complexity and invasiveness of complex patellofemoral reconstruction, combined bony procedures and MPFL‐R resulted in a low redislocation rate, improved physical activity and QoL comparable to values reported after isolated MPFL‐R. Furthermore, sexual activity was improved in 60% of females with preoperative restrictions. Level of evidence IV.
