In short: knock knees in adults (medically, genu valgum) reflect the shape of the bone, usually the femur. Exercises improve strength and tracking but cannot change the bone's angle; a distal femoral osteotomy can, straightening the mechanical axis and unloading the outer knee before it wears into arthritis. In Turkey, correction typically costs $8,000-$18,000 all-inclusive.

What are knock knees (genu valgum)?

Genu valgum, the medical name for knock knees, describes legs in which the knees touch while the ankles stay apart when you stand with your feet together. It is entirely normal in children between roughly ages two and five, and in the great majority it straightens on its own. When knock knees persist into adulthood, or appear later through rickets, injury or arthritis, the inward angle is built into the bone, most commonly the lower end of the femur.

Because the deformity lives in the bone, the honest position on adult knock knees mirrors that for bow legs: strengthening and bracing can help how the knee feels and functions, but only surgery changes the angle itself.

What genu valgum does to the knee

A valgus axis funnels body weight through the outer (lateral) compartment of the knee. Over years, that uneven load wears the lateral cartilage, strains the ligaments on the inner side of the knee, and commonly pulls the kneecap out of its normal track, which is why many knock-kneed adults feel pain on the front or outer knee, especially on stairs and slopes. Realigning the leg spreads load evenly across the joint again, easing those symptoms and protecting the cartilage when correction is done before significant wear.

What causes knock knees in adults?

• Unresolved physiologic valgus from childhood that never fully straightened
• Rickets / vitamin D deficiency during growth
• Growth-plate injury or malunited fracture near the knee
• Inflammatory arthritis (such as rheumatoid arthritis) altering joint alignment
• Load-related progression, which excess body weight can accelerate

Can knock knees be fixed without surgery in adults?

For an adult, non-surgical treatment manages the symptoms of knock knees but does not correct the deformity. A well-designed programme strengthening the glutes, hips and quadriceps improves how the kneecap tracks and can meaningfully reduce pain and instability; weight management lowers the load driving cartilage wear; and insoles or braces can help during activity. All of this is worth doing. What none of it can do is re-angle a femur that has finished growing, so claims that specific exercises will "straighten" adult knock knees are not accurate. In children, the situation is different: knock knees in the 2-5 age range are a normal stage of development and almost always resolve without any intervention.

How knock knees correction surgery works

As with bow legs, correction starts from standing long-leg X-rays that quantify exactly where the deformity is and how many degrees the mechanical axis has shifted. Because valgus usually originates in the lower femur, the standard operation is a distal femoral osteotomy (DFO): the surgeon makes a precise cut near the knee and rotates the bone to the calculated correction angle, holding it with a locking plate. Severe or combined deformities may instead be corrected gradually with an external fixator over several weeks. When a patient also wants additional height, correction can be planned together with lengthening so both goals are addressed in a single recovery.

Recovery after knock knees correction

Recovery mirrors bow-leg surgery. Expect protected weight-bearing for around six weeks while the osteotomy heals, a return to normal daily walking by about three months, and clearance for sport between six and nine months, with physiotherapy throughout to rebuild strength and motion. Both knees can be corrected in one anesthesia or staged for comfort, depending on your preference and the surgeon's assessment. Not smoking and good bone-health measures again improve healing.

Knock knees correction cost in Turkey

Bilateral knock knees correction in Turkey typically costs $8,000-$18,000 all-inclusive, depending on whether correction is acute or gradual and how long you stay. The package covers surgery, implants, hospital stay, imaging, physiotherapy and transfers, and your fixed quote follows a free review of your standing long-leg X-rays.

Knock knees and your kneecap: the patellar tracking problem

Beyond cartilage wear, genu valgum has a specific effect many patients feel long before arthritis: it disturbs how the kneecap (patella) tracks. The kneecap normally glides in a groove at the front of the knee as you bend and straighten. A valgus angle changes the line of pull of the quadriceps, tending to draw the kneecap outward and making it track off-centre against the groove. The result is the front-of-knee ache and instability that knock-kneed adults often notice on stairs, slopes and after sitting for a while. Strengthening the inner quadriceps and the hips can improve tracking and is always worth doing, but where the underlying cause is the bone angle itself, only realignment addresses the root of the problem. Correcting the axis restores a more normal line of pull, which is why patellar symptoms frequently improve after a distal femoral osteotomy.

Acute versus gradual correction: which and why

Knock knees, like bow legs, can be corrected in one of two ways. Acute correction re-angles the femur in a single operation and fixes it with a locking plate, efficient and well suited to moderate, well-defined deformities. Gradual correction uses an external fixator to move the angle a little each day over weeks, and is preferred for large deformities, cases combined with lengthening, or when slow soft-tissue adaptation is safer for the nerves. The decision comes from your standing long-leg X-rays, and the surgeon explains which approach fits your case and why as part of your written plan.

Why patients choose Live Taller Now in Istanbul

Turkey has become the world's highest-volume destination for limb lengthening and deformity correction, and Istanbul sits at its centre. The advantage is not simply price, though all-inclusive packages here run a fraction of US and UK costs, it is the combination of an licensed private hospital, a surgeon who performs these operations as a core part of his practice, dedicated in-house physiotherapy, and coordinators who manage the entire journey in English. Just as importantly, we practise honest candidacy: if your X-rays or health profile make you a poor candidate, or your goal exceeds safe limits, you will be told so plainly, with the reasons. Every figure on this page, the gain limits, the 1 mm/day rate, the recovery windows, reflects real orthopedic practice rather than marketing, and every quote is fixed in writing before you commit.

Risks of knock knees correction, and how they are minimized

Distal femoral osteotomy is a dependable operation, but it shares the general risks of bone surgery: infection, delayed healing at the osteotomy, blood clots, temporary nerve irritation from realignment, and the possibility of under- or over-correction. The safeguards mirror those for any deformity correction: precise planning from calibrated standing X-rays, staged weight-bearing to protect healing, an anticoagulation protocol against clots, a strict no-smoking requirement, and gradual correction where slow soft-tissue stretching is the safer route. Physiotherapy rebuilds strength and range of motion throughout recovery, and follow-up imaging confirms the mechanical axis is exactly where it was planned before you are cleared for full activity.

What results can you expect from correction?

A successful knock knees correction delivers three measurable improvements. On X-ray, the mechanical axis is restored to a straight line through the knee, the objective standard surgeons judge success by. In appearance, the inward angle is reduced or eliminated, and the ankles no longer stay apart when the knees touch. In function and comfort, load is redistributed evenly across the joint and the line of pull on the kneecap is normalized, which often eases the front-of-knee ache and instability that valgus produces. Expectations should be set honestly: the operation is a structural realignment aimed at a healthy axis and long-term joint protection, not a purely cosmetic promise of flawless straightness.

Will both knees be corrected at once?

When both knees are affected, they can be corrected in a single anesthesia or staged a few months apart. Doing both together means one recovery period and one trip, which many international patients prefer; staging means only one leg is in early recovery at a time, which some find easier to manage day to day. Neither is universally right, the surgeon weighs the size of the deformity, your overall health, and your circumstances, and recommends the approach that balances safety with convenience for your case.

Is there an age limit for knock knees correction?

There is no strict upper age limit for correcting knock knees in adults, suitability is judged on bone quality and overall health rather than birthdays. The important requirement is skeletal maturity: in a still-growing child or teenager, surgeons often prefer guided-growth procedures that gently steer the growth plates straight, reserving osteotomy for adults whose plates have closed. In healthy adults of working age, correction is routine; in older patients, the surgeon assesses bone density and any coexisting arthritis, since a knee that is already significantly arthritic may be better served by a different operation. As always, the decision follows a proper review of your standing long-leg X-rays and health history rather than a general rule.
