Pes Anserinus Bursitis

October 2, 2025

Causes, Symptoms & Physiotherapy Treatment | Weaver Physiotherapy Northwich

Pes anserinus bursitis is a painful knee condition that affects many athletes, runners, gym-goers, and even people who don’t consider themselves particularly active. If you’ve been struggling with pain on the inside of your knee, especially when climbing stairs, squatting, or running, pes anserinus bursitis may be the culprit.


At Weaver Physiotherapy & Sports Injury Clinic in Northwich, Cheshire, our experienced physiotherapists regularly help patients recover from pes anserinus bursitis using evidence-based treatment, rehabilitation, and injury prevention strategies. This comprehensive guide explains what pes anserinus bursitis is, what causes it, the symptoms to watch out for, and how physiotherapy can get you back to moving pain-free.


What Is Pes Anserinus Bursitis?


The pes anserinus (“goose’s foot” in Latin) refers to the area on the inner side of the shinbone (tibia) where three major muscles of the thigh insert:

    •    Sartorius

    •    Gracilis

    •    Semitendinosus


These muscles converge and attach at the upper inner tibia, just below the knee joint. Beneath this tendon junction lies a small fluid-filled sac called a bursa, which reduces friction between the tendons and the bone.


Pes anserinus bursitis occurs when this bursa becomes irritated and inflamed, leading to pain and swelling at the inner knee.


Common Causes of Pes Anserinus Bursitis


Pes anserinus bursitis often develops due to overuse, biomechanical issues, or direct stress on the area. Contributing factors include:

    1.    Overuse & Repetitive Stress

    •    Long-distance running, football, cycling, or any repetitive knee flexion can irritate the bursa.

    2.    Poor Biomechanics

    •    Flat feet (overpronation), knock-knees (genu valgum), or weak hip stabilisers increase stress on the inner knee.

    3.    Muscle Tightness or Imbalances

    •    Tight hamstrings or weak quadriceps can overload the pes anserinus tendons.

    4.    Obesity & Deconditioning

    •    Carrying extra bodyweight puts greater pressure on the knee joint and bursa.

    5.    Previous Knee Surgery or Injury

    •    Patients recovering from meniscus surgery or knee arthritis may develop bursitis due to altered movement mechanics.

    6.    Sports Injuries or Trauma

    •    A direct blow to the inner knee can inflame the bursa.


Symptoms of Pes Anserinus Bursitis


The pain from pes anserinus bursitis is usually very specific. Patients typically report:

    •    Pain & tenderness on the inner side of the knee, about 2–3 inches below the joint line

    •    Pain when climbing stairs, squatting, or rising from a chair

    •    Stiffness or swelling around the inner knee

    •    Pain when lying on the affected side with knees together

    •    Discomfort during running, especially uphill


Unlike arthritis, the pain of pes anserinus bursitis is usually localised and does not involve the entire joint.


Diagnosing Pes Anserinus Bursitis


At Weaver Physiotherapy, diagnosis begins with a comprehensive clinical assessment. This includes:

    •    Patient history – When the pain began, activities that aggravate it, medical background

    •    Physical examination – Palpation of the inner knee reveals tenderness at the pes anserinus insertion

    •    Functional testing – Squats, step-ups, and gait analysis to identify contributing movement issues

    •    Differential diagnosis – Excluding conditions like medial meniscus tears, medial collateral ligament (MCL) injury, and knee osteoarthritis, which can mimic similar pain


In some cases, imaging such as ultrasound or MRI may be recommended to rule out other knee conditions.


How Physiotherapy Helps Treat Pes Anserinus Bursitis


Physiotherapy is the gold-standard treatment for pes anserinus bursitis. At Weaver Physio, our Chartered Physiotherapists combine hands-on therapy, exercise rehabilitation, and education to treat both the symptoms and the underlying causes.


1. Pain Relief & Inflammation Reduction

    •    Manual therapy techniques, gentle massage, and modalities such as ice or heat therapy

    •    Electrotherapy or shockwave therapy (if indicated for chronic bursitis)

    •    Advice on activity modification to avoid aggravating movements


2. Restoring Flexibility

    •    Stretching tight hamstrings, adductors, and hip flexors to reduce stress on the bursa

    •    Guided physiotherapy stretches to maintain knee mobility


3. Strengthening Weak Muscles

    •    Targeted exercises for the quadriceps, glutes, and hip stabilisers to improve biomechanics

    •    Gradual progression from bodyweight to resistance-based rehab


4. Gait & Biomechanical Correction

    •    Video gait analysis at Weaver Physio helps identify faulty running or walking patterns

    •    Customised rehab plans to address overpronation, knee valgus, or muscle imbalances


5. Return-to-Sport Rehabilitation

    •    Functional training for athletes including running drills, agility work, and sport-specific conditioning

    •    Education on warm-up, cooldown, and load management to prevent recurrence


Self-Management Tips for Pes Anserinus Bursitis


Alongside physiotherapy, patients can take steps at home to support recovery:

    •    Apply ice packs for 10–15 minutes after activity to reduce inflammation

    •    Use supportive footwear or orthotics if you overpronate

    •    Avoid sudden increases in training volume or intensity

    •    Incorporate regular stretching & strengthening exercises into your routine

    •    Maintain a healthy bodyweight to reduce knee stress


Recovery Timeline


Recovery varies depending on severity, but with the right physiotherapy plan, most patients improve significantly within 4–6 weeks. Chronic cases may take longer, especially if biomechanical corrections are required.


Key to recovery is consistency – sticking with your physiotherapy exercises and avoiding activities that aggravate symptoms until your knee has healed.


Preventing Pes Anserinus Bursitis


Prevention focuses on reducing stress to the knee and correcting risk factors:

    •    Strengthen hips and core to support knee alignment

    •    Stretch hamstrings and adductors regularly

    •    Progress training gradually rather than increasing mileage or intensity too quickly

    •    Wear well-fitted shoes and replace old trainers before they lose support

    •    Book a Runner’s MOT at Weaver Physio for a full biomechanical and gait assessment to catch issues before they become injuries


When to Seek Professional Help


If your knee pain is persistent, worsening, or interfering with daily life, it’s important to see a physiotherapist. Ignoring pes anserinus bursitis may lead to chronic pain, reduced mobility, and compensatory injuries elsewhere.

Persistent pain at the back of the heel can make simple things—walking the dog, climbing stairs, training for the Knutsford 10K or enjoying a run around Tatton Park—feel far more difficult than they should. At Weaver Physiotherapy & Sports Injury Clinic, we provide shockwave therapy ⁠ as part of a structured rehabilitation programme for people with persistent Achilles tendon pain. Our Northwich clinic is easily accessible from Knutsford and supports active adults, runners and sportspeople across Cheshire. The goal is not simply to settle symptoms for a few days. It is to understand why the tendon is painful, improve its capacity for load, and help you return to the activities that matter to you with greater confidence. Achilles Tendinitis or Achilles Tendinopathy? “Achilles tendonitis” is the term most people use when describing pain, stiffness or swelling around the tendon at the back of the ankle. However, when symptoms have persisted for several weeks or months, the more accurate clinical term is often Achilles tendinopathy. Tendinopathy is a complex condition associated with tendon pain, reduced function and lower tolerance to exercise or repeated loading. The tendon may become more sensitive and less able to cope with the demands being placed upon it. It is not always a straightforward inflammatory problem, which is why complete rest, stretching or massage alone may not create a lasting solution. A detailed review of tendinopathy research describes the changes that can occur within painful tendons and the importance of an individualised management approach. Common symptoms include: Pain or stiffness at the back of the heel, especially first thing in the morning Discomfort when walking uphill, climbing stairs or rising onto tiptoes Pain during or after running, football, tennis, gym training or long walks Thickening or tenderness in the tendon Symptoms that improve as you warm up, then return later At Weaver Physio, we assess whether your symptoms are likely to be related to mid-portion or insertional Achilles tendinopathy, and screen for other possible causes of heel and calf pain. If there is concern about a rupture, significant tear or another condition requiring medical investigation, we will advise on the appropriate next step. What Is Shockwave Therapy? Extracorporeal Shockwave Therapy—often shortened to ESWT or radial shockwave therapy—uses controlled acoustic pressure waves delivered through a handheld applicator. It is not an electric shock and does not involve injections or surgery. During treatment, gel is applied to the skin and the handpiece is positioned over the relevant area of the Achilles tendon. The sensation is commonly described as firm tapping or pulsing. Your clinician can adjust the treatment intensity to keep it manageable. Shockwave therapy may be considered for longer-standing tendon pain, particularly where a well-planned rehabilitation programme has not yet delivered the progress you need. It should always be used following a thorough assessment and alongside progressive exercise—not as a standalone “quick fix”. How Shockwave Therapy May Help Achilles Pain Shockwave therapy is thought to influence pain sensitivity and stimulate biological responses within the tendon and surrounding tissues. The practical aim is to create a window in which you can move more comfortably and build strength more effectively. For Achilles tendinopathy, a comprehensive treatment plan may help you to: Reduce pain that is limiting walking, work or sport Improve confidence with daily activity and exercise Progress calf-strength and tendon-loading exercises more successfully Address training errors, footwear issues and movement factors contributing to overload Build resilience for a return to running, sport or long-distance walking Outcomes vary between individuals. Some people notice a change in symptoms early in treatment, while tendon adaptation and improvements in load tolerance typically take longer. We will always discuss realistic expectations and measure your progress against your own goals. Your Shockwave Therapy Assessment Near Knutsford Your journey starts with a detailed physiotherapy assessment. We look beyond the painful spot to understand the full picture, including: Your symptom history and training or activity levels Previous injuries and treatment Calf strength, ankle mobility and balance Achilles tendon tenderness and loading tolerance Footwear, running surface and recent changes in training volume Hip, knee and foot control where relevant This allows us to confirm whether shockwave therapy is an appropriate option and develop a recovery plan tailored to you. Weaver Physio’s team also provides specialist physiotherapy and sports injury rehabilitation ⁠, so your treatment can be integrated with hands-on care, exercise rehabilitation and return-to-sport planning where needed. What Does a Typical Course Involve? A course of shockwave therapy commonly involves three to five sessions, often spaced about one week apart. The exact number and timing will depend on your presentation, response to treatment and rehabilitation goals. Each appointment is combined with guidance on tendon loading. This may include: Isometric calf exercises for pain management Progressive heel raises and heavy slow resistance work Soleus and gastrocnemius strengthening Balance, control and single-leg stability work A gradual return to running, hills, speed work or plyometric exercise Rather than avoiding all activity, we help you find an appropriate level of movement that keeps the tendon challenged without repeatedly exceeding its current capacity. Is Shockwave Therapy Right for You? Shockwave therapy may be suitable if you have persistent Achilles symptoms that have not settled with sensible activity modification and a targeted rehabilitation programme. It is particularly relevant for people who want a non-invasive option before considering more invasive interventions. However, it is not suitable for everyone. Your physiotherapist will discuss relevant precautions and assess factors such as pregnancy, blood-clotting issues, certain medications, recent steroid injection near the treatment area, suspected rupture or other medical considerations. It is also important to seek urgent medical advice if you experience a sudden pop in the back of the ankle, immediate weakness when pushing off, marked bruising or an inability to rise onto your toes. These can be warning signs of an Achilles rupture. Why Choose Weaver Physio? Weaver Physiotherapy & Sports Injury Clinic combines clinical assessment with a practical understanding of sport, training and everyday activity. We are based in Northwich and regularly support patients travelling from Knutsford, Alderley Edge, Holmes Chapel, Middlewich and across Cheshire.

Most people describe shockwave therapy as uncomfortable rather than painful. The feeling is similar to firm tapping against the skin, and the intensity can be adjusted throughout treatment. Mild soreness, redness or tenderness can occur afterwards and usually settles within a few days. How many sessions will I need? Many patients have a course of three to five sessions, usually one week apart. Your clinician will recommend an appropriate plan based on your symptoms, tendon presentation and response to treatment. Can I exercise after shockwave therapy? Light daily activity is usually encouraged, but your clinician may advise avoiding high-impact exercise—such as running, jumping or hard hill work—for a short period after treatment. You will be given clear guidance on what to continue, reduce and progress. Will shockwave therapy cure my Achilles pain? No treatment can guarantee a cure. Shockwave therapy may help reduce pain and support recovery in suitable cases, but lasting improvement usually depends on combining treatment with a progressive loading programme, sensible activity management and a gradual return to sport.
