Is walking good for torn ligaments?

The permission table: the ankle sprain that should walk, and the joint that should be imaged first

Is walking good for torn ligaments is a question that needs a table rather than a verdict, because the answer depends on which ligament, how badly torn and which day, and a reader who takes a yes meant for a sprained ankle onto a knee that cannot bear weight has been given the wrong permission, so the honest page writes the table. Row one is the commonest torn ligament there is, the grade one or two lateral ankle sprain, the ankle rolled under on a kerb or a landing, the outer ligaments stretched or partially torn, swollen and sore but able to take weight. For this row the answer is yes, and early: the ankle sprain literature compared functional treatment, protected weight bearing within pain from the first days with a brace or tape and a progressive exercise programme, against immobilisation in a cast, and found functional treatment returned people to work and sport faster with no worse ankle stability afterwards, so walking is not something a sprained ankle is allowed to do despite the injury, it is part of the treatment, the load telling the healing fibres which way to lie, the muscles around the joint staying awake and the swelling pumped away by the calf. The walk is within pain, on flat ground first, in supportive shoes with the brace or tape on, for short distances that lengthen as the days pass, and it is not a run, a hill or a turn until the physiotherapist says so. Row two overrides every other row and comes before it: any joint that cannot bear weight for four steps, both immediately after the injury and when it is assessed, or that is tender at the bony points the Ottawa ankle and knee rules define, the back edges and tips of the ankle bones, the base of the fifth metatarsal, the navicular, the head of the fibula, the kneecap, is imaged before it is walked on, because those signs mark a fracture until an X-ray proves otherwise and the Ottawa rules exist precisely so that fractures are not walked on under the belief that they are sprains. A reader who cannot take four steps does not have a walking question yet; they have an X-ray question, and the walking table resumes after it.

The complete tear, the rule for every grade, what walking is not, and where collagen sits

Row three is the complete tear, the grade three sprain in which a ligament has parted entirely, the anterior cruciate in a pivoting knee above all, and the grade three collateral tears of the knee and the high ankle sprain that involves the ligaments between the shin bones. For this row walking is as the clinician allows and not as the reader decides, usually with a brace and sometimes crutches in the first days, weight bearing progressing as the swelling settles and the muscles switch back on, and the stop sign is a knee that gives way, buckles or feels as if it will, because each giving-way episode in a cruciate-deficient knee risks the meniscus and the cartilage that the ligament was protecting, and those do not heal the way the ligament might; a reader with a complete cruciate tear walks under a physiotherapist's programme while the surgical conversation, reconstruction or structured rehabilitation, is had with a specialist on their knee and their sport, and does not walk through instability to prove a point. The rule for every row: walk within pain and never through instability. Pain within tolerance during and after is the ligament being loaded at a level it can use, the loading that the healing literature shows produces a stronger and better-aligned repair than rest, while sharp pain, a joint that shifts, catches or gives way, and swelling that returns after a walk are the tissue saying the load was too much, and the distance, the surface and the pace are progressed under a physiotherapist rather than by feel. What walking is not: it is not the whole rehabilitation, which adds strength work for the muscles around the joint, balance and proprioception training that a torn ligament has cost, and sport-specific movement before a criteria-based return; and it is not sped by anything swallowed, since walking loads the ligament and nothing in a tub loads anything. Where collagen sits, for completeness: around fifteen grams with roughly 50mg of vitamin C an hour before a loading session doubled a collagen synthesis marker in a small trial, so some physiotherapists use the pre-loading protocol beside the rehabilitation sessions, and the walk is a loading session of a kind, though the protocol is timed to the programme's exercises rather than to every walk to the shop, a marker adjunct with no ligament outcome trial and no claim. The worked example is that adjunct on its true terms: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, below the protocol's grams, taken for vitamin C's collagen formation sentence through the months a ligament takes, and moving no one off the table above. Is walking good for torn ligaments: for the sprained ankle, yes and early; for the joint that fails four steps, after the X-ray; for the complete tear, as allowed and never through giving way; and for all of them, within pain and under a programme.
