In order to confirm or refute this hypothesis a prospective study has been performed comparing the congruence and sulcus angles and the PT:P ratio in a group of 35 patients with chondromalacia confirmed by arthroscopy and a group of 33 patients with instability, with those of a group of 50 knees in normal volunteers. While there was a statistically significant correlation between an increased sulcus and congruence angle and a high-riding patella in patients with instability, no correlation could be identified in patients with idiopathic chondromalacia. <\/jats:p>","DOI":"10.1302\/0301-620x.68b2.3958019","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:44:12Z","timestamp":1519213452000},"page":"297-300","source":"Crossref","is-referenced-by-count":37,"title":["Radiographic assessment in patellar instability and chondromalacia patellae"],"prefix":"10.1302","volume":"68-B","author":[{"given":"GS","family":"Dowd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G","family":"Bentley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","container-title":["The Journal of Bone and Joint Surgery.
