Surgery For Knee Cap Pain
If your knee cap pain hasn’t been resolved with rehabilitation, your orthopaedic surgeon may recommend an operation called arthroscopic lateral release. This is keyhole surgery that cuts or ‘releases’ the tissues attached to the outer side of the patella (knee cap) called the lateral retinaculum.
Dr. David Colvin, orthopaedic surgeon in Perth. David's specialty is knee and shoulder surgery and sports injuries.
What causes knee cap pain?
Maltracking and tilt of the patella often causes knee cap pain. The knee cap runs in a groove at the front of the knee called the trochlea. When the patella does not run centrally in the trochlear groove, it is called maltracking. A maltracking patellar tilts to the outer side of the knee. The excessive load on the outer half of the knee cap causes pain. Over time, the tissues on the outer half of the knee cap shorten and tighten. The overloaded knee cap can wear, leading to knee cap arthritis.
Without knee cap surgery, we try to stretch the lateral retinaculum that is tight, strengthen the inner quadriceps muscles (VMO), and use taping or a knee cap brace to centralise the knee cap. If this isn't successful, treatment with arthroscopic lateral release surgery may be recommended.
How is a lateral release performed?
The lateral release is performed with keyhole surgery. Arthroscopic knee surgery will achieve two things. Firstly, Dr Colvin can smooth off roughened areas of wear. Secondly, surgery will allow release of the tight lateral retinaculum which will correct the tilt and maltracking of the knee cap. This surgery produces a correction very similar to taping or bracing of the knee cap, but does so permanently.
