Physical Therapy Guidelines For Total Ankle Arthroplasty

Transcription

Physical Therapy Guidelines for Total Ankle ArthroplastyFor the Clinician: The intent of this protocol is to provide the clinician with a guideline of the post-operative rehabilitation for the patients whoundergo Total Ankle Arthroplasty. It is not intended to be a substitute for clinical decision making regarding the progression of a patient’s postoperative course based on their examination/findings, individual progress, and/or the presence of post-operative complications. If a clinicianrequires assistance in the progression of a post-operative patient, they should consult with the referring surgeon.For the Patient: The timeframes for expected outcomes contained within this guideline may vary from patient to patient based on individualpatient differences, surgical techniques, surgeon’s preference, additional procedures performed, and/or complications. Compliance with all therecommendations provided by your physician and physical therapist as well as your active participation in all parts of the rehabilitation process,are essential to optimizing the success of this procedure.Introduction:Ankle replacement is performed as a treatment for end-stage ankle arthritis (See Figure 1). It is typically indicatedin older, lower demand individuals, as the lifespan of an ankle replacement remains less certain than that for hip orknee replacement. Patients that have arthritis (or fusions) involving the joints adjacent to the ankle joint may alsobenefit from an ankle replacement, because it can help preserve accommodative motion so as not to furtheroverload these other diseased areas. Very young, active patients are usually best served with a well performedankle fusion.Figure 1A: Normal Ankle Joint on X-rayFigure 1B: Ankle Arthritis on X-ray (Loss of ankle joint space)This was written and developed by the therapists of MGH Physical Therapy Services.

Physical Therapy Guidelines for Total Ankle ArthroplastySurgical Procedure:In all ankle replacements, the arthritic surface of the distal tibia (lower leg) is removed, as is the arthritic surface ofthe top surface talus (Figure 2). The resected areas of bone are then replaced with the prosthesis. The prosthesistypically has a metal surface on the tibia and talaris sides, with a polyethylene surface that articulates betweenthem to facilitate motion.Figure 2: Tornier Saltos Talaris Total Ankle ReplacementReference: footeducation.comThis was written and developed by the therapists of MGH Physical Therapy Services.

Physical Therapy Guidelines for Total Ankle ArthroplastyAdditional InformationPain and swelling:This is a procedure that can cause swelling for up to 6-12 months post-op. Redness does not necessarily indicateinfection but would be worrisome with the presence of progressive or persistent pain. Significant drainage fromthe wound is usually a sign of infection.Return to work:Return to work at a full sedentary job no earlier than 3-4 weeks post-op. Return to work at a job requiringsignificant amounts of standing or walking no earlier than 4 months post-op. Return to work for jobs with physicalrequirements between the above extremes is individualized (If uncertain, please contact the surgeon).Important: No patient with a total ankle arthroplasty should be doing a job, sport, or activity causingsignificant, repetitive, high impact to the joint.If you have any questions or concerns related to the content of these rehabilitation guidelines, please contact:MGH Physical and Occupational Therapy Services (MG Waltham)781-487-3800Website: http://www.massgeneral.org/physical-therapy/MGH Orthopedics Foot and Ankle617-724-9338Website: http://www.massgeneral.org/ortho-foot-ankle/This was written and developed by the therapists of MGH Physical Therapy Services.
