Medial knee pain can indicate a number of different root causes. These causes include Pes Anserinus Inflammation/Strain, Medial Meniscus/Cartilage Tear, Osteoarthritis, and Medial Colateral Ligament Sprain. These conditions often arise due to overuse and include inflammation or irritation of the structures that make up the medial knee. Each of these conditions has its own well-established treatments that include rest, icing after activity, anti-inflammatory medications, physical therapy, and strength training. Pes Anserinus Inflammation/Strain -- The Pes Anserinus is the joining of three muscles near the inside of the knee. When one of these muscles, muscle attachments, or the bursas underneath the tendons of these muscles becomes inflamed or strained, this spot can become very painful and cause weakness in the knee. Medial Meniscus/Cartilage Tear - Caused by over-rotation or twisting of the knee, hyper-extending or hyper-flexing the knee, impact on the outside of the knee, or simply from overuse. The cartilage or meniscus becomes damaged on the inside portion of the knee causing less integrity of the system that constitutes the medial knee. Osteoarthritis - The cartilage in the knee degenerates and ceases to provide a smooth surface for bones to move along. The lubricating functionality of the joint is negatively affected and causes irregularities in the bone. Medial Colateral Ligament Sprain (MCL) -- the MCL connects the femur (thigh bone) to the tibia (shin bone). It <b>...</b>
