Summary: For adults with a degenerative medial meniscal tear, treatment with 12 weeks of supervised neuromuscular and strength exercises may lead to the same level of function, pain reduction and quality of life over 2 years as treatment with arthroscopic partial meniscetomy, but patients treated with supervised exercise may have greater short-term (3 month) improvement in thigh muscle strength.
