Knee pain

Interesting Facts about Physical Therapy and Health

1-Direct access to physical therapy for neck and back pain can save you money

- Individuals with neck or back pain who see a physical therapist first before going to see a physician have on average $1,543 lower cost through the course of their care compared to those with a physician referral. 1


2-Sham (placebo) surgery may be just as beneficial as actual surgery

- A review of 6 previous research studies on sham surgery compared to actual surgery for many orthopedic conditions has shown that indivifrduals who had sham surgery had similar outcomes compared to those that had the actual surgery. 2


3-Only 44% of total knee replacements in the United States meet criteria to be performed

-In a study done on a group of individuals who received knee replacements, 34% were deemed to be inappropriate for a total knee replacement, 22% were inconclusive, and only 44% met criteria to actually be performed. Considering that more than $20 billion are spent each year on hip and knee replacements in the US it is possible that a great deal of money is spent on surgeries that really shouldn’t be performed. 3, 4


4-One in five individuals who get a spinal fusion require a second spinal fusion within 4 years.

- In a study of 433 individuals that had a lumbar spinal fusion about 20% of those individuals had to have a reoperation to their spine within 4 years. The most common reason for reoperation was pathology to an area adjacent to the initial surgery site. 5 This is especially concerning when considering the outcomes of lumbar fusion. In fact 55.8% of individuals that have a lumbar fusion report that they are no better or worse. 6


5-Meniscus repair surgery does not improve functional outcome compared to physical therapy

-A physical therapy protocol that focuses on knee range of motion, knee strength, and aerobic conditioning that consists of about 9 visits of therapy was just as effective as arthroscopic surgery of the meniscus according to patient reports at 6 months and 12 months. 7


6-Heavy load deadlifts can reduce low back pain

-The once prevailing belief that lifting heavy things was bad for your back can be put to rest. In a study of individuals with persistent (chronic) low back pain it was found that 12 weeks of progressively heavier deadlifting significantly reduces low back pain. Progressive deadlifting with training for proper form was just as effective as other physical therapy training for reducing low back pain. 8


7-When picking a running shoe comfort should be the most important factor

-When it comes to reducing injuries in runners with running shoes or inserts, it appears that the variable that is most important is that the runner select a shoe or an insert that they feel is the most comfortable. The decision on what kind of shoe should be decided by the runner, and not be swayed by fancy jargon used by a salesperson. 9


8- It is a myth that CrossFit is more dangerous than other sports such as running

-In a study from 2018 out of 1032 runners, 198 (19%) of them reported an injury, while out of 144 CrossFit athletes 12 (8%) of them reported injuries. Though the key to avoid injuries in any sport is proper training and skilled coaching. 10


9- Lumbar disc herniations will most commonly resolve on their own with no surgical intervention.

-A recent meta-analysis showed that 66.66% of lumbar herniations will spontaneously resolve with conservative care and no surgery. 11 The most unique aspect of spontaneous disc resorption is that it appears that the most severe cases of disc herniations are also the most likely to spontaneously resolve. 12

10- 50% of all non-contact ACL injuries can be prevented with proper training

-As little as 3 sessions of 20 minutes that includes strength and motor control training over 9 weeks can significantly reduce the risk of having an ACL injury by 50%. 13


11- Back braces and education about lifting techniques are not actually helpful at reducing low back pain

-A review from 2018 done on all past research found that back braces and instruction on lifting technique, regardless of whether or not it was 30 minutes or 4 hours, do not actually reduce the likelihood of someone getting back pain at work. In fact what was actually beneficial was performing exercise interventions such as back and abdominal strengthening, stretching, and cardiovascular fitness training 14


12-Breaks during work help prevent and reduce low back pain

-The best part is that they also do not impede on work production. It is definitely clear that active breaks from work are superior to passive breaks. 15 In this same vein a sit to stand desk can be helpful at reducing low back pain experienced at work. 16


13- Running does not actually increase the likelihood of an individual developing arthritis

-Despite what was once thought that arthritis develops related to overuse of joint; it actually appears that running does not increase the prevalence of arthritis. 17 In fact what we actually see is that recreational running is better for your knee cartilage than a sedentary lifestyle. 18 We see increases in arthritis in the hands linked to obesity which is indicative of the role that inflammation from fat tissue has in the development of arthritis in our bodies. Thus, exercise and maintaining a healthy lifestyle are ideal for reducing the likelihood of developing arthritis. 19


14- In order to improve endurance capacity athletes should include heavy and explosive resistance training to their training program.

-Many endurance athletes are still cautious of adopting heavy resistance training out of fear that it will impair their performance. Heavy lifting with fewer repetitions and sets in major lifts, both powerlifting and olympic lifts are helpful for endurance athletes as it improves neural recruitment of the muscles and decreases the oxygen demand to generate the same amount of force, thus improving running economy. 20
