What Game Ready does, and what Compex does

Game Ready and Compex: one manages pain and swelling, the other rebuilds strength

Two problems that do not call for the same tool

After knee surgery, the patient goes home with two problems that do not call for the same tool. The quadriceps no longer responds and loses strength: that is a muscle problem. The knee is swollen and painful: that is a joint problem. No single device does both. Together, they cover the whole recovery.

The Compex addresses the muscle. Electrical stimulation triggers the contraction directly in the quadriceps. It does not need the voluntary command, which the operated knee blocks by reflex for as long as it is swollen and painful. The muscle works from the first days, several times a day, at home. Recommended by the guidelines after ACL reconstruction and after knee replacement,⁷ it gives three times more effect when it starts in the first week,⁵ and its strength gain is still measurable one year later.⁶

The Game Ready addresses the joint. Cryocompression combines cold and dynamic compression. Cold calms the pain; compression acts mechanically on the oedema and drives venous and lymphatic return. In the trials that measured effusion objectively, cryocompression reduced it more than ice alone.^3,4 And by deflating the knee, it lifts the reflex brake that puts the quadriceps on standby: applied before exercise, it gave 30% more voluntary strength to patients four days after surgery.¹

The first rebuilds the muscle. The second relieves and frees the joint. They are not two options, they are two steps of the same recovery.

Why one without the other leaves a gap

With the Compex alone. The muscle works. But in a knee that stays swollen, inhibition persists, voluntary work stays difficult, pain limits the exercises, and the oedema keeps the cycle going.

With the Game Ready alone. The knee deflates, pain drops, the command gradually returns. But during those weeks, the muscle has only been loaded by what the patient managed to contract, which is little. It has lost strength that will have to be made up.

With both. The knee calms down and is released from inhibition; the muscle works while the command repairs itself; active work becomes possible earlier, on a muscle that has not been waiting.

A recovery in two phases that overlap

In the acute phase, the first days. Priority to the knee: pain, oedema, mobility. Cryocompression several times a day. And already electrical stimulation, from the first week, because that is when it brings the most.

In the rebuilding phase, the following weeks. Priority to the muscle: regular electrical stimulation for as long as the quadriceps has not regained its strength, voluntary exercises in progression, and cryocompression before active sessions for as long as the quadriceps is inhibited, then after exertion to control the inflammatory response.

The order within a single day

A question the patient will ask on day one. The answer comes down to one thing. Prolonged cold reduces the contraction the stimulator produces, while it improves voluntary contraction.^8,2 So:

The one combination to avoid: a full cold session right before stimulation. And never place electrodes on skin still numb from the cold.

What it changes for the patient, and for you

For the patient: a recovery that does not stop at the hospital door. The knee is treated several times a day, the muscle works from the first week.

For you: a patient who arrives in session with a less swollen knee and a quadriceps that responds.

In practice

• Electrical stimulation from the first week, at the maximum tolerated intensity.
• Cryocompression from the return home, several sessions a day.
• Cold before active work for as long as the quadriceps is inhibited.
• Compex before Game Ready within the same session.
