Knee cap pain(Anterior knee pain)


One of the reasons for knee cap pain is

abnormal tracking of knee cap. The treatment

depends on the exact reason for abnormal tracking.


The treatment options are


  1. Insole to correct flat feet
  2. Physiotherapy to balance weak quadriceps
  3. Lateral release (dividing tight band of tissue)
  4. Tibial tuberosity osteotomy (Fulkerson osteotomy)
  5. Reconstruction of a damaged ligament (MPFL) after

dislocation of knee cap (patella)

  1. Tibial osteotomy if the legs are rotated






Dislocated knee cap



Will my leg be in a plaster cast or splint?


Your leg will be in a splint for 6 weeks.

The splint is locked for 3 weeks

with the knee straight.

It is unlocked to allow bending of the knee

at 3 weeks.


When will I start to walk on the operated leg?


You will start to walk the following day with

a pair of crutches putting partial weight through the

operated leg.


What are the risks of operation?


  1. Infection
  2. Nerve and arterial damage
  3. Compartment syndrome (swelling of the leg)
  4. Blood clots in the legs (DVT) and lungs (PE)
  5. Non-union of the bone cut
  6. Rarely persisting knee cap pain


How will you reconstruct the MPFL?


One of the hamstring tendons is used a graft.

Drill holes are made in the knee cap and femur.

The graft is passed through the tunnels made in the

knee cap and femur and fixed with a special screw to

prevent the knee cap from dislocating again.
