Most arthritis treatment involves different ways to decrease inflammation or distract from the pain that it causes.
These can be grouped into three categories:
1. Activity modification
2. Medications
3. Gating
Activity Modification
This is basically finding ways to decrease the force and motion across the hip, which then may decrease inflammation.
The part about activity modification that most people don't like, is that they like their activities. It's hard to ask people to give up what makes them feel good. If you are a runner or walker, it means mixing in swimming or cycling. If you like long distances, it means pulling back. If you carry a pack it means decreasing your load. It definitely helps, but in the end the time we have is short, and progressively decreasing your activity can have diminishing returns.
Using a cane or a walking pole to decrease the forces generated by the muscles acting across the hip can help significantly. The hip is a lever, and the force experienced at the joint can be greatly decreased by decreasing the work of the muscles that cross the hip. The cane is most effective when used in the hand opposite the effected hip.
Weight loss is very effective at decreasing the force experienced by the hip. This is a global lifestyle modification. Decreasing portions, increasing vegetables and lean protein, and finding ways of burning more calories. I will frequently refer people for outside consultation to help with this, as it is not easy and not as simple as it sounds.
"Hip Therapy" by stretching or strengthening the muscles around the hip does not have an intuitive roll. It is akin to having worn out tires on your car and trying to make it better by driving it faster and farther than usual. Some patients report some transient benefit, but this may be secondary to gating or central endorphin release. It may work for a little while, but many report it increases their pain.
Medications
Inflammation is universal in all forms of arthritis and causes pain. The most effective medications include over-the-counter anti-inflammatories like Ibuprofen and Naprosyn. For some patients, they prefer and find greater efficacy in prescription medications like Celebrex (Celecoxib) and Mobic (Meloxicam). In the end, the pharmacologic basis for how they work is very similar, and each can be very effective. Anti-inflammatory medications are most effective when used consistently over time, and not just when there is pain.
Caution must be exercised as prolonged use of any medication can have side effects. Stomach and colonic ulcers, gastric upset, and easy bleeding are the most common for this family, in addition to being potentially toxic to kidney tissue, and may result in some increase in cardiovascular events in some people. They are avoided in patients who take blood thinners.
Acetaminophen is helpful. It is not a true anti-inflammatory, and is independent from the medications above. It acts in the brain and not at the site of inflammation, but it can be effective in decreasing the perception of pain, and in the end, that is what matters. It is typically very safe, but again there is no free lunch, and acetaminophen is toxic to liver tissue in high doses and in people who have decreased liver function.
Cannabinoids (Marijuana) may have anti-inflammatory properties and may have centrally acting analgesic properties. It has an increasing role in pain management. It is not well quantified and can be difficult to prescribe, but many patients who report efficacy. As there are fewer serious negative side effects than any of the classic pharmaceutical medications, I support its use in pain management.
Narcotics and opioids have no sustainable role in treatment of arthritis pain. They increase sensitivity to pain over a short period of time and are addictive.
Gating
Gating decribes the neurologic mechanism of preempting or inhibiting the signal of one stimulus with another. Imagine nerves that carry pain signals as a train track. Only one train can occupy a track at a time.
With gating we put alternate trains on the same track as the pain signals. Pain signals traveling along specific nerve pathways can be blocked by other signals from another more acceptable stimulus in the area. It is neurologic trickery, but it is the result that matters.
Gating methods are great because there are frequently no downside beside time and cost of the treatment. As arthritis progresses, they may no be sufficiently effective.
Injection
Injection modalities for treatment of hip arthritis are limited without much support for long-term efficacy.
Steroids:
The mainstay is corticosteroid (steroid) injection. This treats the inflammatory component of hip arthritis and can be beneficial in some patients, although its efficacy is variable. Steroids may inhibit tissue metabolism and repair, and should be avoided for 90 days before any planned hip surgery. Unfortunately, in patients with advanced arthritis, the duration of benefit of the steroid is limited. Because of this, steroid injection is used primarily for confirmation of a primary diagnosis as well as buying time when hip replacment isn't convenient or desired.
Platelet Rich Plasma (PRP):
PRP may induce an inflammatory biologic response that may include new tissue and vascular ingrowth. Some patients report benefit. There is not good literature to support its use for treatment of hip arthritis, and therefore PRP is usually not covered by insurance.
Stem Cell Therapy:
This injection modality involves harvesting your stem cells (the cells in your body responsible for making/healing new parts when you need them) and injecting them into your hip joint. Current evidence does not support the use of stem cell therapy at this time and it is also not covered by insurance payor or Medicare for this reason. Generating new cartilage is more complex than squirting cells randomly into the hip joint, and frequently by this stage the hip is no longer smooth and round. There are anecdotal reports of benefit, but it is not supported by high quality studies.
Surgery
Surgery for the hip is considered after all other modalities have not provided satisfactory results. Hip arthroscopy and hip replacement are the two available interventions for hip pathology.
Patients who benefit from arthroscopic interventions are young with identifiable anomalies of the hip that are present prior to arthritic degeneration (loss of cartilage) of the joint itself.
