Knee pain is a common occurrence in weightlifters. Squatting and heavy leg presses are power movements great at building muscle mass. Hack squats are notorious for placing undue strain on the anterior portion of the knee. Weightlifters are also frequently involved in other sports including contact ones such as football. Many of these sports predispose to injuries such as knee meniscal tears. Knee surgery is a common occurrence in weightlifters. Knee meniscal surgery in conjunction with weightlifting accelerates the degenerative arthritis curve progression. Knee osteoarthritis or arthritis, is not at all uncommon in weightlifters as they age.
Professional bodybuilders often have to modify their exercise as they age. Treatment options such as prescription anti-inflammatories, cortisone injections, viscosupplementation injections have not been shown to alter the progression of degenerative osteoarthritis. Platelet Rich Plasma (PRP) injections have been advocated, however Platelet Rich Plasma (PRP) is devoid of stem cells. Stem cells are more effective in regenerative responses than PRP, this is due to the nature of PRP and growth factor functioning, as opposed to the mechanisms both known and unknown of stem cells. Stem cells may work in concert with PRP growth factors, yet stem cells are the master orchestrators of the repair process. This weightlifter after consulted with Dr. Dennis Lox opted to have knee stem cell injections. Following this Dr. Lox recommended a structured program for the gym to continue weightlifting, yet avoid activities and exercise that would not be beneficial to the healing response following knee stem cell injections.
