The majority of results of arthroscopic plica excision have described medial plica excision and mostly been limited to small retrospective reviews. Kent et al. summarized the results of arthroscopic treatment of medial plica in studies published since 1980. 38 In all the studies reviewed, patients had 66% to 98% good to excellent outcomes with plica excision. Weckstrom et al. also recently described retrospective results of military recruits with arthroscopic medial plica resection at median 6-year follow-up. 39 Functional results as determined by the Kujala and Lysholm knee scores were good to excellent in 68% of patients.

Few reports exist of pathologic infrapatellar or suprapatellar plica. Demirag et al. 40 and Boyd et al., 41 in small series described 85% to 91% good or excellent results with arthroscopic resection of symptomatic infrapatellar plica, while Bae et al. 42 reported 90% good or excellent results with excision of a complete, symptomatic suprapatellar plica.
