Patellofemoral Arthritis Orthopedic Physical Therapy

Physical Therapy for Patellofemoral Arthritis

Patellofemoral arthritis is a form of knee arthritis that affects the joint between the kneecap and the thigh bone. This part of the knee is heavily involved in stairs, squatting, kneeling, getting up from a chair, walking downhill, running, jumping, and many daily movements. When the patellofemoral joint becomes irritated, symptoms may include pain around or behind the kneecap, stiffness, swelling, grinding, weakness, or difficulty with activities that load the front of the knee.

Physical therapy for patellofemoral arthritis is not one-size-fits-all. The right treatment plan depends on your symptoms, kneecap mobility, knee range of motion, quadriceps strength, hip strength, balance, walking mechanics, stair tolerance, work demands, exercise routine, medical history, imaging findings when available, and goals. A physical therapy evaluation can help determine which mobility, strength, mechanics, and activity factors may be contributing to your symptoms.

What is Patellofemoral Arthritis?

Patellofemoral arthritis involves degenerative or inflammatory changes in the joint where the kneecap glides along the front of the femur. Some people have arthritis changes on imaging with mild symptoms, while others experience pain, stiffness, swelling, grinding, weakness, or reduced function that affects daily life.

This condition often becomes more noticeable with stairs, squats, kneeling, prolonged sitting, getting up from low chairs, walking downhill, or activities that place greater load through the kneecap. Physical therapy focuses on improving knee mobility, building strength around the knee and hip, improving movement mechanics, and helping the knee tolerate daily activity more comfortably.

What causes Patellofemoral Arthritis?

Patellofemoral arthritis may be related to age-related joint changes, prior kneecap injury, patellar dislocation history, previous knee surgery, repetitive loading, kneecap tracking issues, quadriceps weakness, hip weakness, reduced mobility, genetics, activity history, inflammatory factors, or long-term stress through the front of the knee.

Contributing factors may include limited knee range of motion, reduced kneecap mobility, quadriceps weakness, hip weakness, poor single-leg control, limited ankle mobility, altered stair or squat mechanics, swelling, poor load tolerance, or activity habits that repeatedly flare the patellofemoral joint. A physical therapist can help identify which factors appear most relevant to your symptoms and goals.

Common symptoms of Patellofemoral Arthritis

Patellofemoral arthritis symptoms are usually felt around the front of the knee, behind the kneecap, or along the edges of the kneecap. Symptoms may change based on stairs, squats, sitting time, kneeling, walking distance, swelling, activity level, footwear, and how irritated the joint is at the time.

Front knee pain or pain behind the kneecap

One of the most common symptoms of patellofemoral arthritis is pain around the front of the knee or behind the kneecap. The pain may feel dull, achy, sharp, sore, pressure-like, or deep inside the joint depending on the activity and irritation level.

This symptom pattern may be influenced by patellofemoral joint irritation, cartilage changes, swelling, quad weakness, hip weakness, altered kneecap mechanics, or repeated loading through the front of the knee. The goal of care is often to reduce irritation and improve the knee’s ability to tolerate daily movement.

Common signs of front knee pain or kneecap pain

• Pain around, behind, under, or beside the kneecap
• Aching that worsens with stairs, squats, kneeling, or getting up from a chair
• Discomfort with prolonged sitting or walking downhill
• Pain that increases after longer activity days
• Symptoms that improve temporarily with rest, gentle movement, or activity modification

How physical therapy may help front knee pain

Physical therapy may help reduce front knee pain by improving knee mobility, strengthening the quadriceps, hamstrings, glutes, and calves, improving kneecap mechanics, and guiding activity pacing. Your therapist may also help you adjust movements that repeatedly overload the front of the knee.

Pain with stairs, squats, kneeling, or getting up from a chair

Patellofemoral arthritis often becomes more noticeable during activities that load the kneecap. Stairs, squats, lunges, step-downs, kneeling, sitting down, standing up, getting out of a car, or walking downhill may increase symptoms.

This pattern may be related to quadriceps weakness, hip weakness, limited ankle mobility, reduced knee motion, swelling, poor knee control, or the patellofemoral joint not being ready for the current amount of loading. Physical therapy can help rebuild the strength and mechanics needed for these daily movements.

Common signs of stair, squat, kneeling, or chair-related symptoms

• Pain going up or down stairs
• Symptoms with squats, lunges, step-downs, or kneeling
• Difficulty getting up from a chair or using low seats
• Knee pain when getting in or out of a car
• Hesitation, weakness, or reduced confidence loading the affected leg

How physical therapy may help stair and squat pain

Physical therapy may include quad strengthening, hip strengthening, glute strengthening, ankle mobility work, step-down training, squat modifications, sit-to-stand practice, balance training, and movement retraining. The goal is to improve how the knee handles load during the movements that matter most to your daily life.

Grinding, clicking, stiffness, or swelling

Patellofemoral arthritis may cause grinding, clicking, popping, stiffness, swelling, or a feeling of pressure around the kneecap. These symptoms may be more noticeable during stairs, squats, sitting, kneeling, exercise, or after longer activity days.

Knee noises are not always a problem, especially when they are painless. However, painful grinding, swelling, stiffness, locking, or giving way should be evaluated. Physical therapy can help determine whether symptoms appear related to patellofemoral arthritis, strength deficits, mobility limitations, movement mechanics, or another knee condition.

Common signs of grinding, clicking, stiffness, or swelling

• Grinding, clicking, popping, or crunching around the kneecap
• Stiffness after sitting, driving, resting, or exercise
• Swelling or a heavy feeling around the front of the knee
• A feeling of pressure or irritation behind the kneecap
• Symptoms that increase with stairs, squats, kneeling, or repeated knee bending

How physical therapy may help grinding, stiffness, or swelling

Physical therapy may include knee mobility, swelling management strategies, quad strengthening, hip strengthening, movement retraining, activity pacing, and manual therapy when appropriate. Your therapist can help you understand how to progress activity without repeatedly exceeding the knee’s current tolerance.

Difficulty walking, standing, workouts, or daily activity

Patellofemoral arthritis may interfere with walking, standing, stairs, errands, work tasks, hiking, cycling, lower-body workouts, squats, lunges, tennis, pickleball, field sports, or household chores. Symptoms may appear during activity or later as aching and stiffness around the kneecap.

This pattern may be influenced by activity volume, hip strength, quadriceps strength, knee mobility, balance, recovery habits, footwear, walking mechanics, lifting mechanics, or how quickly activity was increased. Physical therapy can help you stay active while reducing repeated flare-ups.

Common signs of daily activity-related patellofemoral arthritis symptoms

• Front knee pain with walking, standing, stairs, workouts, or sports
• Symptoms with squats, lunges, step-downs, kneeling, or prolonged sitting
• Discomfort that lingers after activity or exercise
• Difficulty returning to normal walking distance or training volume
• Needing to reduce workouts, hobbies, or daily activity because symptoms keep returning

How physical therapy may help activity-related front knee pain

Physical therapy may help identify movement, strength, mobility, and workload factors that are increasing irritation. Treatment may include progressive strengthening, gait training, stair mechanics, squat modifications, low-impact conditioning, workload planning, and a gradual return-to-activity plan.

Related conditions and symptoms physical therapy may address

Patellofemoral arthritis can overlap with several knee, kneecap, hip, leg, and movement-related conditions. A physical therapy evaluation can help identify whether symptoms appear related to patellofemoral joint irritation, quad weakness, hip weakness, swelling, tendon irritation, gait changes, or another contributing factor.

Knee osteoarthritis

Knee osteoarthritis can affect multiple areas of the knee, including the patellofemoral joint. Symptoms may include knee pain, stiffness, swelling, grinding, weakness, and difficulty with stairs, walking, or squatting.

Physical therapy may help improve knee mobility, strength, balance, walking mechanics, and daily activity tolerance.

Patellofemoral pain syndrome

Patellofemoral pain syndrome causes pain around the kneecap and front of the knee. It may overlap with patellofemoral arthritis when front knee pain is aggravated by stairs, squats, sitting, running, or getting up from chairs.

Physical therapy may assess quad strength, hip strength, knee control, foot and ankle mechanics, kneecap mobility, and activity habits to guide treatment.

Chondromalacia patella

Chondromalacia patella refers to cartilage irritation or softening under the kneecap. It may cause front knee pain, grinding, stiffness, or discomfort with stairs, squatting, kneeling, or prolonged sitting.

Physical therapy may focus on reducing irritation, improving strength, improving mechanics, and helping the knee tolerate activity more comfortably.

Quad weakness or hip weakness

Quadriceps and hip weakness can affect kneecap mechanics, knee control, stair tolerance, squat mechanics, walking form, and confidence loading the leg. These strength deficits may increase stress through the patellofemoral joint.

Physical therapy may include progressive strengthening, balance work, gait training, stair mechanics, and functional movement practice.

Patellar tendinopathy

Patellar tendinopathy may cause pain just below the kneecap, especially with jumping, running, squatting, or explosive activity. It can overlap with patellofemoral arthritis when the tendon and kneecap joint are both sensitive to loading.

Physical therapy may include load management, progressive strengthening, tendon loading, landing mechanics, and return-to-activity progressions.

Meniscus-related knee pain

Meniscus irritation can cause joint line pain, swelling, clicking, catching, or discomfort with twisting, squatting, or stairs. Some meniscus changes may occur alongside knee arthritis and may or may not be the main driver of symptoms.

Physical therapy may help improve knee strength, range of motion, balance, and activity tolerance while monitoring symptoms that may need medical evaluation.
