PURPOSE: In vitro studies have shown promising results for balloon-guided inflation tibioplasty. It was our hypothesis that this technique may be safe and effective for use in depressed lateral @entity174 . METHODS: We performed a prospective study of all @entity1 suffering from a depressed lateral @entity174 , managed in our institution with inflation tibioplasty and a resorbable @entity78 bone substitute injection, between January 2012 and December 2013. Twenty @entity1 , mean age 54.3        12. 8  years, suffering from a depressed lateral @entity174 ( @entity1605 and III) were included. We then aimed to evaluate at a minimum follow-up of one year: (1) the rate of complications, (2) the clinical outcome ( @entity3331 and @entity571 Outcome (KOO) and 12-Item Short Form Health Survey (SF-12) scores); and (3) the radiographic outcome (evaluated by CT-scan). RESULTS: No peri-operative complications occurred. In one @entity1 , @entity78 substitute was found in the infrapatellar fat pad on post-operative radiography with no clinical or radiographic consequences at one year. At one year after surgery, the KOO subscores were: Pain 80 (range 64-93), other symptoms 81.3 (69-93), daily living activities 81.9 (46-99), sport 65.83 (20-100), and quality of life 67.04 (31-100). The SF-12 activity component was 40.4 (28.6-52.2) and SF-12 mental component 47.71 (28 - 67.1). The mean depressed step-off of the lateral joint decreased from 10.7       4.8 mm pre-operatively to 2.7        1.7  mm post-operatively (p   <   0.0001). CONCLUSION: Our observations suggest that the use of balloon-guided inflation tibioplasty with injection of a resorbable bone substitute is safe, and results in a high rate of anatomic reduction and good clinical outcomes in @entity1 with @entity308 . LEVEL OF EVIDENCE: Therapeutic Level IV.
