Runner's Knee
Pain behind or around the kneecap is one of the most common complaints in active patients. When mileage, mechanics, and muscle imbalances combine, the patellofemoral joint takes the hit. We treat the cause, not just the symptom.

Understanding Runner's Knee
Runner's knee does not always resolve with rest. The mechanics driving it need to be addressed.
Runner's knee is the colloquial name for patellofemoral pain syndrome (PFPS), irritation of the cartilage and soft tissue around the kneecap (patella) where it contacts the femur. The patellofemoral joint absorbs significant compressive force during running, squatting, and stair climbing. When the patella does not track correctly through its groove, or when load exceeds the tissue's capacity, pain and inflammation develop.
Despite the name, runner's knee is not limited to runners. It is common in cyclists, hikers, skiers, and anyone who repeatedly bends the knee under load. It accounts for up to 25 percent of all running injuries and is one of the leading reasons active patients seek orthopedic and sports medicine care.
At Joint Freedom, we address the patellofemoral joint directly. From early cases responsive to laser and load reduction to chronic cases requiring PRP.

Who Gets Runner's Knee?
Runner's knee is common in active people of all ages. Female runners and those with specific biomechanical patterns are at higher risk.
Common Risk Factors
- Female sex (higher Q-angle increases patella stress)
- Overpronation or flat feet
- Weak hip abductors and external rotators
- High weekly running mileage or rapid mileage increase
- Downhill running or stair training
- Previous knee injury

Runner's knee is the most common overuse injury in recreational and competitive runners
Symptoms and When to Seek Treatment
Runner's knee is identifiable by where and when the pain occurs.
Common Symptoms
- Dull, aching pain around or behind the kneecap
- Pain that worsens with running, squatting, stairs, or prolonged sitting
- Grinding or crackling sensation when bending the knee
- Stiffness after rest or sitting for extended periods
- Swelling around the front of the knee in some cases
See a Specialist If...
- Pain persists beyond four to six weeks of activity modification
- Running distance is significantly limited by pain
- Pain is worsening rather than plateauing
- Knee gives way or feels unstable on descents
If you are unsure, schedule a free consultation. We will tell you honestly whether treatment is right for you.
Common Causes of Runner's Knee
Three factors that combine to drive most cases.
BIOMECHANICAL
Patellofemoral Malalignment
The kneecap does not track evenly through its groove during knee bend. Weak hip stabilizers, tight IT band, and flat feet all pull the patella off course. Repeated malalignment irritates the cartilage beneath the kneecap and the surrounding soft tissue.
TRAINING OVERLOAD
Too Much Too Fast
Rapid mileage increases are the most common trigger. The patellofemoral joint is highly load-sensitive. Weekly mileage jumps beyond 10 percent, back-to-back long runs, and downhill running all raise injury risk. Training patterns matter as much as anatomy.
MUSCLE WEAKNESS
Hip and Quad Deficits
Weak gluteus medius, tight hip flexors, and quad strength imbalances between legs shift load onto the kneecap. Runners with hip weakness place significantly more stress on the patellofemoral joint than those with adequate hip strength.
How We Diagnose Runner's Knee
Movement assessment and training history are as important as imaging.
Clinical History and Movement Assessment
We assess training load, shoe wear, running surface, and symptom pattern. Single-leg squat mechanics and step-down tests reveal hip strength and patella tracking patterns.
Imaging When Indicated
X-rays assess alignment. MRI or ultrasound identifies cartilage softening, bone marrow edema, or soft-tissue contributors to patellofemoral pain.
Personalized Treatment Plan
Based on your mechanics, training goals, and imaging findings, we build a regenerative and rehabilitation protocol around your running schedule.

What You Can Do at Home
Addressing mechanics and training load is central to every runner's knee protocol.
What Helps
- Hip strengthening: clamshells, side-lying abduction, single-leg bridges
- Quad strengthening in a pain-free range (terminal knee extension, step-ups)
- Foot support with orthotics if overpronation is contributing
- Gradual return to running with walk-run intervals
- Ice after activity to manage symptoms
What to Avoid
- Continuing full mileage through significant pain
- Ignoring hip and foot mechanics while only treating the knee
- Prolonged complete rest without addressing biomechanical contributors
- Downhill running or stairs during active flares
How We Treat Runner's Knee
Two evidence-based options, combined based on severity and chronicity.
REGENERATIVE MEDICINE
PRP Therapy
Platelet-rich plasma injected into the inflamed patellofemoral tissue under ultrasound guidance. PRP reduces chronic joint inflammation and supports cartilage health. Indicated for persistent cases where conservative management has plateaued.
LIGHTFORCE XLi
Laser Therapy
Class IV deep-tissue laser to reduce pain and inflammation around the patellofemoral joint. Often the first in-clinic step for early runner's knee, used alone or alongside PRP for chronic presentations.
Which Treatment Is Right for Your Runner's Knee?
Severity and training goals determine the protocol.
01
EARLY OR FIRST EPISODE
Laser and Load Reduction
Class IV laser series combined with targeted hip and quad strengthening and a modified running plan. Most early cases resolve within four to eight weeks when biomechanical contributors are addressed.
02
CHRONIC OR RECURRENT
Add PRP
PRP series with Class IV laser support. Addresses persistent patellofemoral inflammation and cartilage irritation. Full effect typically by 8 to 12 weeks with continued improvement over several months.
03
ACTIVE RUNNER
Training-Integrated Protocol
We do not ask you to stop running. We modify load, build hip strength, and use in-clinic treatment to allow continued mileage while the joint recovers. Race schedules and event timing are factored into every plan.
How Joint Freedom Compares
What you are actually weighing when you consider your options for runner's knee.
 | Cortisone Shot | Surgery | |
|---|---|---|---|
| What it does | Reduces cartilage irritation, calms inflammation, restores function | Temporarily suppresses inflammation | Modifies knee structures surgically |
| Recovery time | None to minimal | None | 8 to 16 weeks |
| Addresses root cause | Yes | No | Sometimes |
| Long-term results | Durable; full effect typically by 8 to 12 weeks | Temporary; does not address mechanics or cartilage | Reserved for failed conservative care; variable outcomes |
| Risk of side effects | Minimal | Moderate with repeat use (cartilage thinning risk) | High (surgical risk, long rehab) |

Questions About Runner's Knee
Answers from our clinical team.
Rest alone rarely fixes runner's knee. The mechanical cause (typically hip and core weakness, sometimes mobility limitations) does not improve through rest. When you return to running, the same pattern produces the same pain.
Usually not. Most patients reduce volume and intensity for two to four weeks, modify training, and progressively return. Complete rest is rarely the right answer for runner's knee.
For chronic or recalcitrant cases, particularly those with imaging-confirmed cartilage irritation, PRP can be appropriate. For typical first-time PFPS, Class IV laser plus loading correction is usually the right starting point.
No. Runner's knee (PFPS) is pain at the joint surface behind the kneecap. Patellar tendonitis is pain at the tendon below the kneecap. They have different causes and treatments. See the patellar tendonitis page for that condition.
Often yes, with realistic timeline planning. The earlier we address the mechanical cause, the more confident we can be about race day. Schedule a consultation with your race date in mind.
Surgery for typical runner's knee is rare and reserved for cases with confirmed structural problems unresponsive to comprehensive conservative care. The vast majority of cases resolve without surgery.
PFPS is one of the most common diagnoses in youth runners. We treat adolescent cases regularly and coordinate with parents and coaches on return-to-activity plans.
