It is well documented that the strength of the muscles around the knee and hip are important factors in the treatment and rehabilitation of the knee. If you have a sore knee you usually find that the muscles around that knee are weaker than the other side – presuming that there is nothing wrong with the other knee.
You can test the relative strength of the muscles surrounding your knee yourself by
- Doing 15 repetitions of knee extensions, and hamstring curls in the gym using the same weight on each leg. Firstly with the painful knee and then with the good knee and see if there is a difference.
- You can do the same with the leg press but you will be measuring the difference of the combined buttock and quadriceps strength. Research shows that buttock strength is an important factor in knee rehabilitation.
- If you don’t go to the gym you can check out the relative strength by the number of step downs or step ups you can do on one leg compared to the other. Or you could measure the thigh circumference on one leg compared to the other. The thigh of the stronger leg will usually have a bigger circumference.
There are specific exercise regimes you need to do to rectify this imbalance. See you local physiotherapist for help with this.
