Surgical treatment and rehabilitation of medial Hoffa XXXX fixed by locking plate and additional screws: A retrospective cohort study.

@entity1 @entity174
PURPOSE: Hoffa @entity174 fixed by only using a single plate or lag screws might be not strong enough to achieve direct stability. The goal of this study is to determine the functional outcome of the surgical treatment and rehabilitation of medial Hoffa @entity174 by a locking plate combined with cannulated or lag screws. METHODS: A total of 13 @entity1 suffering isolated medical @entity174 were identified during the study period (2005.February-2013.February) and retrospectively analyzed. All the @entity174 were treated by open reduction via the medial approach, and internal fixation by a locking plate combined with cannulated or lag screws. Early active rehabilitation including tele-rehabilitation for rural @entity1 with restricted weight bearing was instituted after the surgical treatment. The radiological and functional outcome analysis was performed by using Knee Society Score (KSS), the range of movement (ROM), and the stability of fixation of the @entity1 during 24 month follow-up. RESULTS: The bone union of medial @entity174 was achieved in all @entity1 . The articular surface of medial femoral condyle was anatomically reduced. There was no loss of reduction and fixation. All @entity1 achieved satisfactory knee joint function and regained their walking ability with good clinical results through early postsurgical rehabilitation. Ten @entity1 (77%) had 0  -130   range of motion with full extension; two @entity1 (15%) had 0  -115   range of motion; one @entity1 (8%) had 0  -110   range of motion. The KSS of all the @entity1 were more than 80, and the scores of seven @entity1 (54%) were more than 85. CONCLUSION: Fixation with a locking plate and cannulated or lag screws for medial Hoffa @entity174 seemed to be effective and reliable for achieving anatomical reduction, and gave satisfactory functional results when coupled with aggressive rehabilitation.
