Challenges due to chronic orthopedic disability (address with OT):

• Disease of a body part
• Fear/Anxiety
• Change in body image
• Decreased functional ability
• Joint deformity
• Pain


Hip Precautions – Posterolateral Approach

6 to 8 weeks:
• No hip flexion greater than 90˚
• No internal rotation
• No adduction (crossing legs or feet)


Hip Precautions – Anterolateral Approach

6-8 weeks:
• No external rotation
• No adduction (crossing legs or feet)
• No extension
• Abduction may also be prohibited


Biologic Fixation

Use of bony in-growth instead of cement to fix the prosthesis. Used in younger people; increases the strength of the fixation and decreases possibility of loosening. Identical precautions to cemented method, but may involve additional weightbearing restrictions.


Unicompartmental Knee Arthroplasty (UKA)

Partial knee replacement. Indicated if there is medial or lateral compartmental damage between the femur/tibia. Often placed with minimally invasive technique, allowing greater knee flexion (up to 90˚) more quickly after surgery. Increased stability obtained immediately due to limited disruption to ligaments and joint structures.


Total Knee Arthroplasty (TKA)

Total knee replacement. Indicated when two or more compartments of the knee are damaged. Various prosthetics based on medical condition/activities performed by client.
• FIXED WEIGHT-BEARING: allows only flexion/extension
• ROTATING PLATFORM/MOBILE WEIGHT-BEARING: allows slight rotation normally available in knee (for younger, more active people or women; more risk of mechanical failure)


Precautions for Knee Replacement

• Start out-of-bed activities first day after surgery
• Ambulatory device may be used for greater stability
• May use knee immobilizer/brace to preserve alignment if joint is unstable
• Avoid excessive rotation for up to 12 weeks
• No restriction on flexion/extension; maintains mobility
• May use continuous passive motion (CPM) device to provide slow movement to improve ROM and reduce edema
• Avoid rotation of knee while weightbearing on it
• Avoid prolonged static positioning (standing/sitting) of knee
• Refrain from kneeling


Bed Mobility post Knee Replacement

• No restrictions that dictate bed mobility procedures
• Supine position most recommended, with knee fully extended (encourages full extension required for ambulation)
• May put bolster under knee for pain control
• Pillow/wedge can be used when side-lying on non-op side
