Femoral Implant Rotation
Tibial Rotation
Patellar lateralization

The most common complication of TKA is abnormal patellar tracking.  A normal Q angle is the most important variable in proper patella tracking. It is critical to avoid surgical techniques that lead to an increase in the Q angle. 

Common Surgical errors include:

  • Internal rotation of the femoral component.
  • Medialization of the femoral component.
  • Internal rotation or medialization of the tibial prothesis.
  • Placing the patella prosthesis lateral on the patella.
  • Placing the patella prosthesis to low on the patella.
  • Cutting the patella bone to much or too little.
  • Not doing a lateral release when indicated.
  • Using the wrong design of prosthetic patella implant.
  • Choosing a femoral component with an unfriendly sulcus.
  • Using a femoral component with a too wide intercondylar box.

Partial Knee Replacement

Depending on where arthritis affects the knee, patients may have a partial implant

General indications: Partial knee replacement is intended for use in individuals with joint disease resulting from degenerative and post-traumatic arthritis, and for moderate deformity of the knee.

Contraindications: Partial knee replacement surgery is not appropriate for patients with certain types of infections, any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complications in postoperative care, compromised bone stock, skeletal immaturity, severe instability of the knee, or excessive body weight.

Joint school is a service specifically for people that are about to undergo a hip or knee replacement. We have conducted this gathering for the past 10 years at the offices of Dr Botes in Paarl.

It focusses on patient education and lets you know what to expect through the various steps you will experience, from preparing for admission to recovery at home. Our joint school takes place on a Friday morning bi-weekly. It is a group session compromising up to about 12 persons which include patients and family members. It lasts approximately 1.5 hours and gives you information about :

  • The operation and recovery process
  • Anesthetic options
  • How long you are expected to stay in hospital
  • Exercises to aid your rehabilitation
  • How to avoid and manage complications
  • How to protect yourself against future  infections
  • Any specific preparation you may need to make in readiness for discharge

Providing you with this information will help you to ensure that you have realistic expectations and that you will be equip to take an active role in your recovery process and rehabilitation.
