Hip Non-surgical Treatment

When you are told you have arthritis of your hip or knee joint, Dr. Thornton-Bott will explain the treatment options that are available and these will usually begin with non-surgical treatment.

These will be

Pain Relief Medication

Pain Relief MedicationInitially, the simplest treatment is for you to take analgesia, or pain relieving medication. Some patients with heart issues, asthma, stomach problems or kidney problems may not be able to take an anti-inflammatory medication a it can make these worse. Dr. Thornton-Bott will review your medical history and discuss this with you.

If you are taking regular simple pain medication and still have pain, then you may require stronger medication. Some patients are scared they will get addicted to these stronger medications, but if taken appropriately for severe pain, this is unlikely, and all options will be discussed so you can make an informed decision.

Activity Modification

Activity ModificationChanging what you do can have a dramatic effect on your pain. This can be a small change, such as how you climb the stairs (see physiotherapy below). More major modifications will include changing from jogging (a high impact sport) to cycling, which is low impact and causes less pain. Dr. Thornton-Bott will discuss these options with you, and your physiotherapist can advise and help you with these changes too.

Physiotherapy

PhysiotherapyExercise therapy has been shown to help with both pain and stiffness in patients with osteoarthritis. Sometimes, patients who have been booked for a joint replacement get such a good result from physiotherapy that they no longer require the operation, or at least the operation can be delayed for months or even years!

The exercise regimen will be developed specifically for you by our qualified Physiotherapists who have extensive experience in patients with OA of the hip or knee. Some patients can manage many exercises and others only a few. The aim is to maintain a good range of motion and ensure you are walking as well as you can and as comfortably as you can. Simple measures will be discussed with you such as pain free ways to climb stairs and get out of a chair. These may seem obvious, but just by changing the way in which you do these everyday activities may significantly reduce your pain.

Weight Loss

Weight LossWhen you put your left foot on the ground and swing your right foot forward during walking, you can put 2-3 times body weight through your hip and knee.

This is simple mechanics. The knee and hip are not in the centre of the body, but are a distance away from your centre of gravity, hence body weight multiplied by distance of the hip or knee from the centre of gravity creates a force that is greater then the body weight. (See the fig below) When running, these forces are higher, and when going up and down steps the forces are up to 5 times body weight.

Increased weight, and when excessive, obesity is a universal issue in the developed world. Not only can it cause significant medical problems such as early onset diabetes, it also puts a huge strain on your hips and knees. The articular cartilage resists the forces placed upon the joint, but if these forces are excessive the cartilage can become damaged and become arthritic. When you get arthritis, the increased weight increases the force in the joint and thus increases the pain.

Millions of years of evolution have created a skeleton in a woman of 160cm tall to have an ideal weight of around 55kg, giving her a Body Mass Index (BMI) of 21.5. As such, if you are a woman of 160 cm and weigh 80kg, you are putting up to 75kg (3x25) more through your hip or knee than it is designed to carry. You will have a BMI of 31. Importantly, the reverse is also true, in that if you do weigh 80kg and are 160cm and lose weight, then for every 1kg you lose you will be taking 2-3 kg off your joints. This is why weight loss in patients with osteoarthritis can have a huge impact on your pain. It is common for patients who have moderate OA of the hip or knee and successfully lose weight to also lose some or most of their pain. It can feel very difficult to exercise because of the pain, but weight loss is also 80% of what you eat and 20% what you do. If you are unable to do any exercise, then weight loss is 100% of what you eat.

It is easy to say ‘Lose weight!’ and much harder to do it! There are many avenues and help that is available to patients who want to, or need to lose weight and Dr. Thornton-Bott can discuss these with you. We are here to help you. There are programs that we can introduce you to so you give yourself the best chance. We are here to listen to what you as a person can and cannot manage.

If your arthritis is advanced, then weight loss will not change the need for surgery, such as joint replacement. However, losing weight will make the surgery easier, your risks lower and your rehabilitation easier.

Walking Aids

Walking Aids‘I don’t want a walking stick, people will think I’m old!’ This is a common comment from patients who have arthritis in their hip or knee. However, a walking stick works! The design of the skeleton means that the centre of gravity does NOT pass through the hip, rather the hip joint is roughly 10-15 cm out from the centre of gravity. This means that the muscles around the hip work as a system of levers, (remember levers and moments in physics at school?) These muscles (Abductors) work by pulling on the femur and pelvis to keep the pelvis stable whilst standing and walking. As explained above, when walking you put 2.5-3 times your body weight through the hip joint because of this mechanism of levers and moments.

I’ll explain- When you lift your LEFT leg from the floor to swing it forward during normal walking, your body weight (W in the fig below below) will act through the centre of gravity (centre of the body, at a distance B) and the pelvis will want to pivot around the RIGHT hip joint (the one you are now standing on) and drop down. The gluteus muscles (Abductors) contract on the outside of your RIGHT hip, pulling on the femur and pivoting around your RIGHT hip joint to keep your pelvis level and stop your LEFT hip dropping down. As the Abductors are closer to the hip (distance A) than the centre of gravity, the muscles have to pull quite hard to counter the weight of your body pivoting around the right hip at distance B. This muscle force causes an increase in the joint reaction force (JRF) force through your RIGHT hip. If you have right hip arthritis, then this mechanism will exacerbate your pain. The use of a walking stick in your LEFT hand (for right hip OA) creates an assisting push on the LEFT which reduces the force required by the RIGHT hip abductors, reducing the force in the joint and reducing the pain. Try it... it really works!

A similar effect works on the knee. And of course, you could get a flashy walking stick and look dapper!

Steroid Injection

Steroid InjectionAn aspect of osteoarthritis is inflammation. This is why you may get swelling of the knee, but also pain. Anti-inflammatory medications are good as a baseline but sometimes are not enough to keep the inflammation at bay. In these cases, a steroid injection can be beneficial. Corticosteroid is a potent anti-inflammatory and many patients with early to moderate OA will have a good result, with moderate or even complete pain relief. The benefits from a steroid infection can last from a few weeks up to a year in some cases. If the pain relief lasts for several months it can be repeated. However, in more severe OA, steroid injections are usually not beneficial, and if the benefits are short lived, the next best option will be surgery.

The steroid injection is a very simple injection that is performed by Dr. Thornton-Bott in his rooms when required into the knee. Because of the depth of the joint, steroid injections into the hip are performed with image guidance such as x-ray or low dose CT scan and therefore not in the rooms.
