How to tell if ligaments are healing?

The order of arrival: six signs that a ligament is healing, in the sequence the biology produces them

How to tell if ligaments are healing is a question that readers want answered with a sign, something to look for in the mirror or feel in the joint, and the honest answer is a sequence rather than a sign, because a healing ligament announces itself in a fixed order that follows the three phases of its repair, and a reader who knows the order can read not only whether the ligament is healing but where in its healing it has reached, which is the more useful thing to know. The first sign is the swelling and warmth falling, over the first days. The inflammatory phase that begins the moment a ligament tears fills the joint and the tissue around it with fluid and inflammatory cells, and the joint is swollen, warm and bruised; as the damaged fibres are cleared and the growth factors that will recruit fibroblasts are released, the inflammatory phase does its work and ends, and the swelling begins to fall from around the third day and is much reduced by the end of the first week in a sprain of the ankle or the knee's medial collateral, with the bruise tracking down toward the toes or the shin as gravity drains it. The second sign is the pain at rest leaving, over the first week or two, as the inflammatory chemicals that sensitised every nerve ending in the joint are cleared with the swelling, so that the ache that kept a reader awake on the second night is gone by the end of the second week and the joint hurts only when it is used. The third sign is the range of motion returning, over the following weeks, as the scar bridges the gap and the joint is moved within the protection of its brace; a joint that could not be bent or straightened fully because of swelling and guarding regains its range, with the stiffness first thing in the morning and after sitting the last part to go, since the healing tissue and the fluid around it stiffen when still. The fourth sign is the pain on load leaving, and it leaves in order of load, as the scar strengthens enough to bear each: walking on the flat stops hurting before stairs, stairs before a jog, a jog before a hop, a hop before a cut or a landing, and a reader can read the scar's strength from which load has stopped hurting and which has not, which is the order the accelerable column on the speed up ligament healing page progresses through. The fifth sign is the joint testing stable when a clinician stresses it: the examiner takes the joint and applies the force that opens it in the direction the ligament restrains, the ankle tilted inward, the knee pushed sideways, and where in the first days the joint opened and the ligament's ends could be felt to be apart, the bridge now takes the tension and the joint stops where the other side stops, which is the sign that the ligament itself, rather than the swelling and the muscles around it, has healed, and the only one of the six that examines the ligament directly. The sixth and last sign is the confidence returning, on single-leg standing, on uneven ground, on landing from a hop, on turning at speed, as the proprioceptive repair that balance training drives catches up with the structural repair; the mechanoreceptors in the ligament that were torn with its fibres and the reflexes they fed are restored by use rather than by time, and a reader who has not done the balance work can have a ligament that passes the stress test and a joint they still do not trust, which is the three phases' last phase on the heal ligaments faster page and the one most often left undone.

The two signals that lie, the signs of not healing and what each means, and the adjunct beside the balance work

Two signals lie, and the honest page names them because between them they account for most of the re-tears and most of the unnecessary worry that follow a ligament injury. The first false signal is the absence of pain, and it is the one most mistaken for healing. Pain leaves a healing ligament as the inflammation ends and the scar bears the load in question, which happens when the scar has perhaps a third to a half of its eventual strength, in the animal studies that have measured a healing ligament's failure load against time; the collagen in the scar goes on maturing for a year after the pain has gone, type 1 replacing type 3, fibrils growing and aligning, cross-links forming, and none of that maturation hurts or stops hurting, so that a joint which feels healed at four weeks is a joint whose scar would re-tear under the load that tore the original, and a return to sport on the signal of no pain is how a healed sprain becomes a re-tear and a re-tear becomes the chronic instability described among the three weaknesses on the weak ligaments page. The fifth and sixth signs, stability on a stress test and confidence on single-leg tasks matched against the other side, are the signals to return on, and the fourth sign's order of loads is the route to them. The second false signal is the scan. A healing ligament looks thickened, irregular, heterogeneous and abnormal on ultrasound and magnetic resonance imaging for a year or more after the injury, because that is what a maturing scar looks like, and a scan at six weeks shows a ligament that appears far worse than the stress test says it is, worrying the reader and sometimes the clinician while adding nothing to the examination's finding that the bridge takes tension; a scan is for the first days, to find a fracture, a gap or an interposed structure that changes the plan, and for the ligament that fails to progress, and not for checking on a ligament that is passing the signs in order. The signs of not healing are the sequence running backward or stalling, and each has a meaning that sends the reader back for examination rather than forward into the programme. Swelling that persists past the second week or returns after activity suggests an injury inside the joint, cartilage or meniscus, or a fracture that the first assessment missed, and an X-ray by the Ottawa rules or a scan is now warranted. A joint that gives way, that buckles under the reader on a step or a turn, suggests either a gap that scarred open because the ends were apart and the first door has closed, or a proprioceptive repair that has not been done, and the stress test tells the two apart. A joint that locks or catches, that sticks at a point in its range or clunks past it, suggests a loose fragment of cartilage or bone or a torn meniscus and is a surgeon's question. Pain that worsens as the programme progresses, rather than easing in order of load, suggests the load has run ahead of the scar or that something other than the ligament is injured, and the programme is stepped back and the joint re-examined. The honest expectation for a ligament that is healing is the six signs in order over weeks to months by grade, and the honest response to a sign out of order is a clinician and not a scan, a supplement or a harder week. Collagen's one ligament trial sits beside the sixth sign: 5g a day for six months in athletes with chronic ankle instability improved a stability score and cut recurrent sprains against placebo, in lax ligaments long healed, which is the proprioceptive and functional territory of the last sign, so the adjunct belongs beside the balance work that brings confidence back, at the trial's powder dose, if anywhere, and no collagen trial has moved any of the first five signs. The worked example is that adjunct at habit scale, stated on its true terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C at 15% of its reference value plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, below the 5g trial dose, carrying vitamin C's collagen formation sentence for cartilage and bones and no ligament claim. How to tell if ligaments are healing: by six signs in a fixed order, with no pain and a clear scan not among them, and a sign out of order sent back to the examiner.
