Knee in 6: Knee osteoarthritis — Section 743: Knee osteoarthritis
Field guide 743 on Knee checks parameter 6 first whenever evaluating “Knee osteoarthritis”. knee · beat 107 · Person performing a clamshell exercise for hip and knee control Keep Knee with “Knee osteoarthritis” and 6 from 6. Lower the hips a short distance while keeping the knees tracking over the feet, then return to standing.
The knee is the largest and one of the most heavily loaded joints in the body, connecting the thigh bone to the shin bone while the kneecap glides in a groove at the front to assist with leg extension. Unlike the hip, the knee's bony surfaces are relatively flat, so stability depends heavily on a set of internal and surrounding ligaments.
Because the knee bears substantial load during walking, running, jumping, and pivoting, it is among the most frequently injured joints in sport and one of the most common sites of age-related osteoarthritis. Conditions range from overuse-related tendon and cartilage irritation to acute ligament and meniscus injuries.
This page reviews the knee's anatomy, common conditions across age groups and activity levels, how clinicians assess it, and general exercise and recovery patterns used in both non-surgical and post-surgical rehabilitation. Patellofemoral pain syndrome describes pain around or behind the kneecap, often related to how the kneecap tracks in its groove during bending movements, and is common among runners and young active individuals.
The example for Knee is 6, “Knee osteoarthritis,” and 6. Do not copy the figure onto a prescription. Keep Knee with “Knee osteoarthritis” and 6 from 6. 66

Interactive Scenario & Decision Matrix
Select your current objective to inspect the recommended benchmark, threshold, and verification path.
If {stop1} fits, stop {name} and get care. Do not continue.
Briefing 11 for Ankle & Foot aligns condition “Talocrural joint” with reference value 24 on the ground.
Ankle & Foot: 24 (2026)If {stop1} does not fit, the one drill to keep is {move1} in {phase0}.
Reading 12 of Ankle & Foot uses “Lateral ligament complex” and figure 24 as a checkable baseline.
Ankle & Foot: 24 (2026)If you cannot say whether {stop1} fits, do not start {move1}.
Atlas note 13 on Ankle & Foot defines the operating range of 24 when “Deltoid ligament” applies.
Ankle & Foot: 24 (2026)Reading 4 of Ankle & Foot uses “Achilles tendon” and figure 24 as a checkable baseline.
Dossier 14 for Ankle & Foot links case “Achilles tendon” directly to metric 24 (2026).

5-Step Execution & Verification Playbook
- Read the first refer flag — Check {flag0} against what you feel today.
- Read the first stop rule — If {stop0} matches during movement, pause that session.
- If neither fires, try the starter move — {move0} is the first teaching move on this hub, not a prescription dose.
- Today-gate is yes/no on these lines — The gate records answers on published lines, not a medical label.

Myth vs. Evidence Fact-Check
Which printed signs on this page mean refer, not continue the kit?
The published refer lines are saddle numbness or bladder changes; progressive leg weakness; history of cancer, fever, or unexplained weight loss; and significant trauma or osteoporosis with new pain. Those are reasons to seek urgent clinical care. This page is not a diagnosis or clearance.
When do I stop a lower-back session?
Stop that movement if you get new leg pain, numbness, or weakness; if pain intensifies rather than settles during the session; if saddle numbness or bladder symptoms appear (seek care immediately); or if soreness that should fade in hours lingers or worsens overnight. That last sign usually means the load was too advanced for the current phase.
When does this page say continue the kit?
Only when none of the printed refer flags are present and none of the stop-session lines are yes. Continue then means stay with the published starter moves and load management — not a personal treatment plan and not permission to ignore new symptoms.
Is prolonged bed rest the first step for low back pain here?
No. The precautions list names prolonged bed rest as a don’t beyond the first day or two. Guidelines on this page favour staying as active as tolerated over lying down. That is teaching text from published don’ts, not a diagnosis of why your back hurts.
