Musculoskeletal System

Outpatient orthopedic clinic — patient information

A 68-year-old woman is referred to outpatient physical therapy after a right primary total knee arthroplasty (TKA; cemented, posterior-stabilized) for end-stage osteoarthritis. She was discharged home on postoperative day 2 and received home health physical therapy for 2 weeks.

Medical history: type 2 diabetes mellitus (most recent hemoglobin A1c 6.9%), hypertension controlled with lisinopril, and BMI 32 kg/m². Medications also include oxycodone as needed and aspirin 81 mg twice daily for deep vein thrombosis prophylaxis.

Social history and goals: she lives alone in a two-story home with her bedroom on the second floor (14 steps). Her goals are to climb the stairs to her bedroom reciprocally, walk her dog 1 mile, and return to volunteering at a library.

Current status: the incision is healed with no drainage. She used a front-wheeled walker at the initial outpatient visit and has used a single-point cane on level surfaces since week 5. She has attended therapy 3 times a week and reports full adherence to her home exercise program. Today is week 6 after surgery.
