Patellofemoral Pain Syndrome

Date:
By Tommy

 

Does your knee get sore while you are walking or running? Does it hurt when you go to stand up after sitting for extended periods of time or walking down stairs? Is it hard to pin point where the pain is coming from like it is in the knee or behind the knee cap. You may have a condition known as patellofemoral pain syndrome.

Patellofemoral pain syndrome is one of the most common knee complaints of both the young active sportsperson and the elderly. It is the medical term for pain felt behind your knee cap, where your patella (knee cap) articulates with your thigh bone (femur). This joint is known as your patellofemoral joint.


Patellofemoral pain syndrome, is mainly due to excessive patellofemoral joint pressure from poor knee cap alignment, which in time, affects the joint surface behind the knee cap.


Relevant findings can include

- reduced quadriceps strength
- iliotibial band tightness
- inward rotation of the hip
- gluteal muscle weakness
- positive trandelenburg sign
- decreased calf length
- over pronated or flat feet
- laterally tracking patella
- tight hamstrings
- tight hip flexors

What is the best plan for treatment?

“Please keep in mind this is the most ideal plan for treatment and your outcome will vary depending on personal circumstances such as how long you have been experiencing symptoms, compliance to treatment recommendations, advice/exercises prescribed and if you are able to attend follow-up appointments”

Stage 1 (0-2 weeks)

Treatments can include

- soft tissue releases along the vastus lateralis / iliotibial band and maintenance aimed at reducing tightness in the area to assist with the knee cap alignment eg. foam rolling

- correct any misalignment of the hip/pelvis, leg and foot with or without orthotics

- education about walking, stairs, squat and lunge alignment/ form

- prescription of correct application of ice principles as needed

- activity modifications to prevent aggravations

- knee or foot strapping as needed

Stage 2 (2-4 weeks)

- introduction of evidenced based strength training  

- physio to prescribe to you the correct prescription of exercise based on your individual assessment

- start with priority areas first

- continue early therapy interventions as needed

Advice in the first 4 weeks or longer

- limit deep squats and lunges into pain

- avoid sustained kneeling

- avoid going up or down stairs if painful

- do not walk or climb steps pigeoned toe (feet turned inwards)

- do not knock your knees during walking, squatting

- avoid high impact sports unless cleared by physiotherapist

Stage 3 (4-8 weeks) 

- Progression of rehabilitation exercises focusing on correct alignment

- Work on core stability and introduce more dynamic control exercises in standing

Final stage (8-12 weeks )

- Work on high end dynamic strengthening exercises for full return to sports and work

 

When should I see improvements?

Most patients will start to see some reduced pain the first 2 weeks but this time can vary depending on the length / severity of your symptoms and if we were able to follow through the whole treatment plan.

 

How long will it take to get back to normal?

Once the pain has reduced you may consider that you are back to normal and finish treatment.  

However, the pain has reduced only as the inflammation has subsided.  The healing of the cartilage behind the knee cap is slow due to a poor blood supply in the area and can take up to 12 weeks for a structural repair of the cartilage.

Performing the correct retraining of the muscles to control the alignment of your knee will see your injury rehabilitated to its potential.

This gives the you the best chance of managing the injury in the long run as the misalignment of the patellofemoral joint if not completely rehabilitated can re-occur when you return to full activities.

Please keep in mind that this is a team effort to get you better, so lets work together for a better outcome.
