Knee Conditions

Knees tell us a lot by how they hurt: a pop and swelling, a catch, or stiffness that built over years.
Torn ACL
A pop, fast swelling, and a knee that gives way.
Torn Meniscus
Joint-line pain with catching or locking.
Knee Osteoarthritis
Stiffness after rest, pain on stairs, swelling after activity.
Knee Pain in Older Adults
Knee pain over fifty, treated conservatively first.
Post-Traumatic Arthritis
An old injury that keeps causing problems.
Inflammatory Arthritis of the Hip and Knee
Swollen, warm, stiff joints, often several at once.

What it is

Torn ACL

The ACL runs through the center of the knee and stops the shin from sliding forward and rotating under the thigh.
When it tears, it does not heal, and the knee loses the stability it needs for cutting and pivoting.Half of ACL tears come with a meniscus or cartilage injury at the same time.

Torn ACL

Symptoms

A pop at the moment of injury, swelling within hours, and difficulty bearing weight at first.Once the swelling settles, the knee feels unstable or gives way with pivoting, stairs or uneven ground.
Some patients walk normally in a straight line and only notice the problem when they return to sport.

Swelling within hours

Torn ACL

Causes

Most tears are non-contact: planting and cutting, landing from a jump, or a sudden stop.Skiing, basketball, soccer and football account for many. Direct blows to the knee cause the rest.Female athletes tear the ACL at several times the rate of males in the same sports.
Torn ACL

How We Diagnose It

The exam is often diagnostic once swelling allows it.X-rays rule out fracture. MRI confirms the tear and shows the meniscus, cartilage and other ligaments.We see acute knee injuries within days so the plan can start early.Ski season is ACL season in Utah Valley; we see acute knee injuries within days so the plan starts before the swelling settles. Dr. Christensen, Dr. Taylor, Dr. Wallentine and Dr. Carlson operate at Utah Valley Hospital and Spanish Fork Hospital.
Torn ACL

Treatment Options

Patients who want to return to pivoting sports, or whose knee gives way with daily life, are offered ACL reconstruction with a tendon graft. Repairable meniscus tears are fixed at the same time.Lower-demand patients may do well with rehabilitation and a brace. Either way, early motion and quadriceps strength come first.
