Knee pain is common for runners and knee injuries are very common in athletes who engage in cutting sports, such as soccer, football, basketball, rugby and lacrosse.
- Anterior Cruciate Ligament (ACL) tear: damage to the fibrous tissue running diagonally through your knee that serves in the main restraint in keeping the shin bone in place, preventing your knee from overextending and providing side-to-side support
- Meniscus tear: twisting and/or awkward knee flexion that causes damage to the fibro-cartilage pad that sits between the thigh bone and shin bone
- Kneecap dislocation: when a sudden change in direction puts your kneecap under stress or slips it to the outside of the knee
- Knee sprain: stretching or tearing of one or more of the knee ligaments
- Lateral collateral ligament injuries: partial (sprain) or full tear of the thin ligament that runs on the outside of the knee and keeps the joint stable
- Patellofemoral pain syndrome (front of the knee pain, sometimes referred to as runner's knee): excessive shifting of the patella from activities that involve knee bending
- Patellar tendonitis (sometimes referred to as jumper's knee or knee tendonitis): inflammation or tearing of the tendon connecting the kneecap to the shin
- MCL sprain: the most often sprained ligament in the knee, the medial collateral ligament, occurs when the knee is forced inward with a stress or impact to the outer side of the knee
- Posterior-lateral corner injury: trauma to the knee, a posterior lateral force directed to the inside of the knee, knee hyperextension or excessive knee rotation that damages the static and dynamic stability of the posterior lateral knee
Diagnosis of knee injuries
Life, and sports, puts a lot of wear and tear on your knees. For runners in particular, it may be difficult to know when to see a doctor for knee pain while running. To tell normal pain from more serious signs of injury, look out for sharp pains inside the knee or along the joint lines.
Your doctor will ask questions about the injury, the history of your knee pain and your symptoms and perform clinical tests to measure joint laxity. He or she may order X-rays or MRI scans to verify the diagnosis if significant swelling is present or the exact structures involved are difficult to identify. Clinical measures, tests and imaging will also be used to rule out or evaluate concurrent injuries. In some cases, the knee injury may be given a specific grade to determine its severity and guide treatment planning.
Nonsurgical treatments for injuries of the knee
Injections may be used to reduce joint pain and inflammation associated with knee injuries like cartilage tears, degenerative meniscus and arthritis-related issues. Steroid injection can help improve function, and for less complicated first-time injuries, can be effective as part of a nonsurgical treatment program, which may include wearing a knee brace and participating in physical therapy. Your physician may use musculoskeletal ultrasound to help guide your injection into the joint. Musculoskeletal ultrasound improves accuracy when treating you with steroid injections in the office, and it is used for deeper joints, joints with poor anatomic landmarks and joints with little to no joint space. This technique uses sound waves to create images of the joint and to identify the needle used to inject the joint helping the physician guide it to the affected area. This technique is done in the office and does not expose you to radiation.
Natural Joint Fluid Treatment
This treatment, also known as hyaluronic acid injections, uses an injectable substance made from the building blocks of cartilage to create the type of cushioning cartilage provides. It is primarily used for arthritis of the knee. Those who respond to this treatment can experience relief for up to six months or longer, and this treatment can be repeated if pain returns.
Depending upon the type of knee problem you have, we may suggest lifestyle changes to help reduce the pain and stress on your knees. Your exercise prescription might include low- or no-impact exercises such as swimming or biking, avoiding activities with running and/or twisting and adding moves to improve the strength of your quadriceps. It is also believed that strengthening your hamstrings and gluteals is important to knee health as well. This is part of a current research study at The Ohio State University Wexner Medical Center.
Lifestyle changes like losing excess weight can also reduce the risk of knee problems.
Surgical treatments for ACL tears, meniscus tears and other knee conditions
Knee microfracture surgery repairs significant acute damage to small areas of knee cartilage. An arthroscope (tubular instrument with an affixed camera) is inserted into an incision made in the knee. Small holes (microfractures) are made in the bone near the damaged cartilage. Cells from your bones are released through the microfractures and create new fibrocartilage.You will need crutches to keep the weight off your knee for six to eight weeks, which will help the new cartilage grow.
Kneecap Dislocation Surgery
A direct blow to the kneecap (patella) in contact sports or pivoting injury to the knee are often the causes of a kneecap moving out of place (dislocation). Initial dislocations can often be corrected by wearing a brace for a few weeks and following up with physical therapy. Imaging is often needed to see if a cartilage lesion occurred with the dislocation.In repeat cases where ligament damage occurs, medial patella femoral ligament (MPFL) reconstruction may be necessary. MPFL reconstruction rebuilds the ligament, using a graft from the femur to the kneecap to help prevent further dislocations.
Osteochondral autograft replaces injured cartilage and underlying damaged bone using your own tissue. It is common for knee repair but can be used to repair other joints as well. In this procedure, the injured cartilage and underlying bone are removed. An autograft (replacement cartilage and bone from another part of the patient or knee) is then substituted.The injured area can usually bear weight within four to six weeks. Activity is gradually increased. Athletes can typically return to sports in about six to nine months.
Autologous Chondrocyte Implantation
Autologous chondrocyte implantation (ACI) provides pain relief from larger areas of cartilage damage and cartilage injuries. ACI is a three-stage procedure:Stage 1: Cells are taken from another part of the patient’s knee.
Stage 2: The cells are grown in vitro for about four to six weeks.
Stage 3: The cells are reintroduced into the affected area in the knee under a patch, ultimately forming new cartilage.
Crutches are needed for at least six weeks and up to three months, depending on the condition and other factors of the individual patient. Ongoing rehabilitation is required and essential for cartilage growth, patient mobility and strength.
