Event Description
This report is being filed after the review of the following journal article: kim, g. B. , kim, k. -i. , song, s. J. , and lee, s. H. (2019), increased posterior tibial slope after medial open-wedge high tibial osteotomy may result in degenerative changes in anterior cruciate ligament, the journal of arthroplasty, vol. 34 (9), pages 1922-1928 (korea, south). The aim of this retrospective study is to evaluate the changes in ptsa and the acl before and after mowhto through 2-staged arthroscopic findings and verify whether the acls would be affected by the changed ptsa. Between july 2010 to march 2016, a total of 128 patients (21 male and 107 female) with 164 knees, with a mean age of 57. 2 ± 5. 1 years (42-67) underwent mowhto and concomitant arthroscopy. Surgery was performed using a medial locked plate system (tomofix; depuy synthes, solothurn, switzerland). Plate removal and concomitant second-look arthroscopy were usually recommended for 2 years after index operation. The mean follow-up period was 70. 2 months (23-104). The following complications were reported as follows: in 5 males and 29 females (45 knees), their acl had become worse (progressed group) after the second-look arthroscopy. In a (b)(6) year old female patient, ¿stage 2¿ acl with no synovial coverage was observed at first-look arthroscopy viewed from the anterolateral standard portal. At 26 months postoperatively, the second-look arthroscopy showed ¿stage 3¿ acl with partial tear of some fibers. This report is for an unknown synthes plate/screws constructs. It captures the reported female patients whose acl had become worse (progressed group). This is report 2 of 3 for (b)(4).
