Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

Multimodal Pain Relief After Total Knee Replacement

Knee pain or injuries are very common and have numerous causes. Knee pain can emerge from delicate tissue wounds like ligament sprains and muscle strains. Bone conditions like knee joint pain, Osgood Schlatters, and biomechanical dysfunction can also cause knee pain. Treatment can include basic knee mobilization techniques, taping, massages or knee strengthening exercises completely through a careful recovery method after knee replacement or reconstruction.

Physiotherapy can help you overcome the pain and increase your strength and flexibility. A physiotherapist can suggest you a number of treatments and also help you understand your issue and get you back to your everyday routine. Physiotherapists are said to be successful in getting rid of the source of the knee pain by diagnosing a cause. This includes tightness around the knee and treating it with stretching and exercises.

Following are some of the exercises a physiotherapist might generally recommend for knee pain:

Hamstring stretch: Stretching keeps you flexible and increases your scope of movement, or how far you can move your joints in different directions. It additionally helps you reduce your chances of injuries and pain. Continuously warm up with a five minute walk first. Lie down when you are prepared to stretch your hamstring. Circle a bed sheet around your right foot, use the sheet to pull the leg up and hold for twenty seconds and then lower the leg. Repeat twice and switch legs.
Calf stretch: Use a chair for balance. Bend your left leg. Step back with your right leg and gradually straighten it behind you. Press your left heel toward the floor. You should feel the stretch in the calf of your back leg. Hold for 20 seconds. Repeat twice and then switch legs.
Straight leg raise: It helps build muscle strength to give support to the weak joints. Lie on the floor. Twist your left knee, foot on the floor. Keep the right leg straight, toes pointed up. Tighten your thigh muscles and raise your right leg.
Quad set: With these, you don't raise your leg. Just tighten the thigh muscles, also called the quadriceps, of one leg at once. Begin by lying on the floor. Keep both legs on the ground, loose. Flex and hold the left leg tense for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Cushion squeeze: This move strengthens your legs from the inside so that they can support the knees. Lie on your back, both knees facing inwards. Place a cushion or a pillow between the knees. Press your knees together, squishing the cushion between them. Hold for five seconds and then relax. Do three sets of ten repetitions. Switch legs after every set.
Heel raise: Stand tall and hold the back of a seat for support. Lift your heels off the ground and rise on the toes of both feet. Hold for three seconds. Gradually lower both heels to the ground. Do three sets of ten repetitions.
