OCS Surgical & Post-Operative Care

Question 1

What is the primary goal of post-operative care following total knee arthroplasty?

Accepted Answer

Prevent infection and restore knee function

Answer

The primary goals of post-operative care following total knee arthroplasty are multifaceted. Preventing infection is critical to avoid serious complications that could compromise the new joint and patient health. Simultaneously, restoring knee function through early mobilization and physical therapy is essential for the patient to regain mobility, reduce pain, and improve their quality of life.

Question 2

Which complication is most common after spinal fusion surgery?

Accepted Answer

Blood clots

Answer

Deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE), commonly referred to as blood clots, are a significant risk after spinal fusion surgery. Prolonged immobility during and after surgery, along with surgical trauma, increases the risk of venous stasis and hypercoagulability. Prophylactic measures like early ambulation and anticoagulants are often employed to mitigate this common complication.

Question 3

What is the key purpose of a CPM (Continuous Passive Motion) machine post-surgery?

Accepted Answer

To promote joint flexibility and prevent stiffness

Answer

A Continuous Passive Motion (CPM) machine gently and continuously moves a joint through a prescribed range of motion without active muscle engagement from the patient. This passive movement is crucial for preventing the formation of scar tissue and adhesions, which can lead to joint stiffness and contractures post-surgery. By maintaining joint mobility, it aids in the recovery of full range of motion and promotes healing.

Question 4

What is the first line of treatment for post-operative swelling following a knee surgery?

Accepted Answer

Ice, elevation, and compression

Answer

The R.I.C.E. protocol (Rest, Ice, Compression, Elevation) is the gold standard for managing acute post-operative swelling and inflammation. Ice therapy constricts blood vessels, reducing fluid accumulation and pain. Elevation uses gravity to drain fluid away from the surgical site, and compression helps limit swelling while providing support to the injured area.

Question 5

When should a patient begin weight-bearing activities after hip replacement surgery?

Accepted Answer

6-8 weeks post-surgery

Answer

While some hip replacement protocols allow for earlier weight-bearing, a period of 6-8 weeks post-surgery is often recommended for significant weight-bearing activities. This timeframe allows for initial bone healing and soft tissue recovery around the prosthetic joint, reducing the risk of dislocation or implant loosening. The exact timeline can vary based on the surgical approach and individual patient factors.
