Bone health, joint health, and skin conditions require modern medical care. Orthopedics, rheumatology, and dermatology are the appropriate disciplines. CrystalStones.com describes the classical mapping; we do not recommend using it for medical timing. If you have a bone, joint, or skin condition, see a doctor.
How does Capricorn map to the body?
Capricorn rules the bones, knees, and skin in classical medical astrology, the body's structural framework. Saturn rules Capricorn, and Saturn was associated in Renaissance practice with the body's cooling, drying, structuring functions.

The mapping
What the tradition mapped
Classical melothesia assigned Capricorn the bones, the knees, and the skin, the regions the tradition read as structural under Saturn. Modern anatomy does not use this mapping.
History
What this historically meant
Capricorn in classical melothesia governs the bones, knees, and skin, the body's structural framework. Saturn rules Capricorn, and in Renaissance practice Saturn was the planet of structure, time, and the body's cooling-drying principle. Saturn-ruled herbs were considered for skeletal and rheumatic complaints. The doctrine of melothesia gives Capricorn the body's most architectural territory.
The symbolic logic is intact: Capricorn is the cardinal-earth sign, the structure-builder, and the bones are the body's structure. Modern integrative practitioners sometimes still reference this when working symbolically with skeletal-system issues.
The modern caveat
Bone health, joint health, and skin conditions require modern medical care. Orthopedics, rheumatology, and dermatology are the appropriate disciplines. CrystalStones.com describes the classical mapping; we do not recommend using it for medical timing. If you have a bone, joint, or skin condition, see a doctor.
Medical astrology is a historical symbolic system, a real and well-documented chapter in the history of Western astrology, not medical advice. The classical rules (Manilius, Culpeper, Hellenistic and Renaissance practitioners) are described here for their cultural and reflective interest. CrystalStones.com does NOT recommend timing surgery, medication, fertility decisions, or any other medical care around moon signs. If you are facing a medical decision, talk to a qualified physician. The classical rule is symbolic; your doctor is not.

Questions
Frequently asked questions
Why did the classical sources give Capricorn the bones?
Symbolic logic: Capricorn is the cardinal-earth structure-builder, and the bones are the body's structure. Saturn (Capricorn's ruler) is the planet of architecture and time.
Which crystals has tradition paired with the Capricorn region of the zodiac body?
Smoky Quartz, Obsidian, and Black Tourmaline are the contemporary symbolic pairings, Saturn-resonant grounding stones. Symbolic only.
What did classical practitioners believe about the knees and Capricorn?
Classical practitioners read Capricorn as the knees' sign and left that region alone while the Moon passed through it. Modern orthopedic surgery does not use the rule. Talk to your surgeon.
