The inclusion criteria were as follows: skeletally mature patients with recurrent or habitual patellar dislocation and an increased TT\u2010TG distance, treatment with MPFLR combined with a TTO procedure or isolated MPFLR, and reporting of clinical outcomes and complications. Each\u00a0study was assessed for quality and the level of evidence.

The average Coleman score was 71.56 (range, 55\u201083). The threshold for an increased TT\u2010TG distance ranged from 16 to 20 mm in the included studies. Similar good postoperative outcomes were reported in patients with an increased TT\u2010TG distance treated with MPFLR with versus without a TTO procedure.

The postoperative redislocation rate ranged from 0% to 4.2% in the TTO\u2010with\u2010MPFLR group, and no redislocation was found in the isolated MPFLR group.
