[Rehabilitation pathway after knee arthroplasty with mega prosthesis in XXXX ].

@entity1 @entity421 @entity158
INTRODUCTION: The knee is the most frequent location for @entity421 (60%). Until 30 years ago @entity1 with @entity421 were treated with an amputation of the affected limb; today 85% of these cases are treated with a "Limb Salvage" procedure, through replacement of the affected bone with a mega prosthesis implant. AIM: To measure functional recovery of @entity1 with a knee mega-prothesis and how rehabilitation impacts on quality of life (QOL); another aim is to define rehabilitation guidelines to manage these @entity1 in the rehabilitation pathway. METHODS: A sample of outpatients with knee mega-prosthesis were selected in the follow-up orthopedic oncology surgery between march and may 2013. We measured the functional outcome using the multidimensional standardized Musculoskeletal Tumor Society scale (MSTS) that gives a score (0-5) for each of 7 items: @entity158 , range of motion, stability, deformity, strength, functional activity, emotional acceptance. RESULTS: The sample included 28 outpatients. The median MSTS score was 29 (min 19, max 33) equal to 83%. Only 14 @entity1 (50%) followed a correct rehabilitation path after surgery. DISCUSSION: 21 cases got "excellent" outcomes and 3 "good" (based on MSTS classification). In few cases (n 4) the outcome was "fairly good", related to necessity of a prosthesis surgical revision based on instability of implant (because of usage). Quadricep strength is the item that most affects the final score. There is a statistically significant correlation between high scores and @entity1 who have recently undergone surgery. We found higher scores in @entity1 that followed a physiotherapy program after surgery: the difference was statistically significant. CONCLUSIONS: Mega-prosthesis implants give satisfactory functional outcomes. These outcomes keep high score in time. It is recommended to follow the guidelines described in the purposed rehabilitation program.
