The tibial plateau is the top of the shinbone, the flat surface the thighbone rests on to form the knee joint. A fracture here, from a fall, a sports injury, or a higher-energy impact, involves the joint surface itself, which makes restoring a smooth, well-aligned surface the central goal.
Because the joint surface is involved, how much the fracture is displaced or depressed strongly influences both treatment and the long-term health of the knee. These fractures also need a careful check of the surrounding soft tissues and the leg's circulation.
Why the joint surface matters
An aligned, smooth joint surface lets the knee glide and share load evenly. When a fracture leaves the surface depressed or stepped, it raises the long-term risk of arthritis, which is why displaced tibial plateau fractures are realigned and fixed.
Symptoms and urgent checks
A tibial plateau fracture causes pain, swelling, and an inability to bear weight after the injury. Because of the energy involved, the evaluation also checks the soft tissues, the ligaments, and the leg's circulation, since significant swelling can occasionally threaten the muscles' blood supply and needs urgent attention.
Dr. Lee evaluates the fracture with X-rays and usually a CT scan to map the joint surface, and examines the soft tissues, ligaments, and circulation. Non-displaced fractures with a well-preserved joint surface are treated without surgery, with protected weight-bearing and early motion.
Displaced or depressed fractures are fixed surgically to restore the joint surface and alignment, supporting it with plates and screws and, when needed, bone graft. The aim is a congruent surface and a stable knee, which is what protects against later arthritis.
Non-surgical treatment
Non-displaced fractures with a preserved joint surface are treated with protected weight-bearing, bracing, and early motion, monitored with imaging to be sure the alignment holds.
Surgical treatment
Displaced or depressed fractures are realigned and fixed with plates and screws, with bone graft when needed to support a restored joint surface. A congruent, stable surface is the goal, since it influences the long-term health of the knee.
Recovery timeline
Recovery protects the joint surface while restoring motion:
- Weeks 0 to 6Protected or limited weight-bearing with early motion to keep the knee from stiffening.
- Weeks 6 to 12Progressive weight-bearing as healing allows, with continued range of motion and strengthening.
- Months 3 to 6Strengthening and a graded return to activity as the fracture consolidates.
What patients commonly misunderstand
Why this break is different:
- It is a joint injury, not just a broken bone. Because the fracture involves the knee's surface, restoring a smooth, aligned surface matters for the long-term health of the joint, not only for the bone to heal.
- Weight-bearing is limited at first. Putting weight on a healing tibial plateau too early can displace the surface. Protected weight-bearing with early motion is the usual balance.
