Causes of Knee Pain
The knee is a complex joint that depends on cartilage, ligaments, tendons, bursae, and the surrounding muscles, all working together. Pain can develop from injury, degeneration, overuse, or mechanical imbalance, often from a combination of these.
Osteoarthritis
The most common cause of knee pain in adults over 50. Cartilage in the knee joint gradually wears down, narrowing the joint space and allowing bone surfaces to contact each other with insufficient cushioning. Pain, stiffness, and grinding sensations develop progressively. Morning stiffness that eases with movement is characteristic. Chiropractic care improves knee joint mechanics, reduces the mechanical stress, accelerates degeneration, and strengthens the supporting musculature to slow progression.
Meniscus Tears
The menisci are two C-shaped pads of cartilage that cushion and stabilize the knee. A tear, from a twisting injury or from degeneration in older adults, produces pain, swelling, clicking or locking of the knee, and a sense of instability. Minor tears respond well to conservative care. Dr. Caroline evaluates the specific pattern of symptoms to determine what is appropriate and refers for imaging when a significant tear is suspected.
Runner's Knee (Patellofemoral Pain Syndrome)
Pain around or behind the kneecap, especially with activities that load the joint in flexion: running, squatting, climbing stairs, or sitting for extended periods. Runner’s knee is typically driven by a combination of patellar tracking problems, quad and hip weakness, and altered gait mechanics. Treating the knee in isolation without correcting these upstream factors is why runner’s knee recurs so consistently.
Patellar Tendinitis
Inflammation of the patellar tendon, the structure connecting the kneecap to the shinbone. Common in athletes who jump, run, or sprint repeatedly. Pain is felt just below the kneecap and worsens with activity. Radial pressure shockwave therapy is one of the most effective treatments available for chronic patellar tendinopathy, particularly in cases that have not responded to rest and stretching alone.
Iliotibial Band Syndrome
The iliotibial band runs along the outer thigh from the hip to the knee. When it becomes tight and inflamed, it causes sharp pain on the outer side of the knee that is typically worst at a specific point in the running or cycling stride. IT band syndrome is a mechanical problem. Treating the band alone without addressing the hip weakness and pelvic mechanics that cause it to overtighten produces temporary improvement at best.
Bursitis
Inflammation of the bursae that cushion the knee joint. Prepatellar bursitis produces swelling directly over the kneecap, typically from repetitive kneeling. Pes anserine bursitis affects the inner side of the knee just below the joint and is particularly common in people with osteoarthritis and in runners. Laser therapy directly addresses the inflammatory component of bursitis in a way that rest and ice cannot fully reach.
Ligament Injuries (ACL, PCL, MCL, LCL)
Ligament sprains and tears produce pain, swelling, and instability. Minor to moderate sprains respond well to conservative rehabilitation. Significant tears often require surgical evaluation. Dr. Caroline assesses ligament integrity during the evaluation and refers for orthopedic consultation when structural repair is indicated. For partial sprains and post-surgical rehabilitation, the combination of laser therapy, adjustments, and progressive rehabilitation accelerates return to function.
Hip and Pelvis Misalignment
Misalignment in the hip or pelvis alters the mechanics of the entire lower extremity. It changes how the knee tracks through its range of motion and creates asymmetrical loading that concentrates stress on specific structures within the joint. Hip and pelvic adjustments are a core component of knee pain care at Balance Atlanta because the knee often cannot be resolved without correcting the underlying imbalance.
Weak Quadriceps and Glutes
The quadriceps and gluteal muscles are the primary stabilizers of the knee and pelvis, respectively. When either group is weak, the knee absorbs more load than it should and the patella tracks abnormally through its groove. Strengthening these muscles alongside direct knee treatment is one of the most important factors in preventing knee pain from returning.
Gout
A form of inflammatory arthritis caused by uric acid crystal deposits in the joint. Produces sudden, severe pain, redness, and swelling, often in the big toe but also in the knee. Functional medicine evaluation at Balance Atlanta can support uric acid management through dietary modification alongside care for the joint inflammation.
