Calf release surgery, also known as proximal medial gastrocnemius release (PMGR), is a procedure used to reduce tightness in the calf muscle. Calf tightness is a common contributing factor in a range of foot and ankle conditions, including Achilles tendinopathy, plantar fasciitis and forefoot pain.
Mr Edward Dawe is a Consultant Foot & Ankle Surgeon specialising in the assessment and treatment of conditions related to calf tightness, offering both non-surgical and surgical options where appropriate. Clinics are available in Chichester, Worthing and Haywards Heath.
What is calf tightness?
The gastrocnemius muscle forms part of the calf and crosses both the knee and ankle joints. Tightness in this muscle can increase tension through the Achilles tendon and place additional strain on the foot.
This may contribute to a range of symptoms, particularly with walking, running or standing for prolonged periods.
Non-surgical treatment
Initial treatment usually involves non-surgical measures aimed at reducing calf tightness and improving function.
These may include stretching exercises, physiotherapy, activity modification and supportive footwear. A slant board may be used as part of a structured stretching programme.
When is calf release surgery considered?
Surgery may be considered when symptoms persist despite an appropriate period of non-surgical treatment and continue to affect daily activities or sport.
The decision to proceed with surgery depends on the underlying condition, severity of symptoms and individual patient goals.
Calf release procedures
There are several different surgical techniques described to address calf tightness. These include proximal medial gastrocnemius release (PMGR), Strayer, Baumann and Hoke procedures, as well as open Achilles tendon lengthening.
In many cases, PMGR is an appropriate option as it allows targeted release of the gastrocnemius muscle while preserving overall function.
This procedure may be suitable for a range of patients, including those who are active and wish to return to sport, as well as those with more general activity-related symptoms.
Compared to more extensive foot and ankle procedures, recovery is often more straightforward, although this varies between individuals.
How is PMGR performed?
PMGR is performed through a small incision at the back of the knee. The procedure involves releasing part of the gastrocnemius muscle to reduce tension in the calf and Achilles tendon.
The aim is to improve flexibility and reduce the mechanical load contributing to symptoms.
Recovery after calf release surgery
Recovery following PMGR is usually more straightforward than more extensive foot and ankle procedures, although timelines vary between individuals.
Patients are typically able to mobilise early, with a gradual return to normal activities guided by symptoms and rehabilitation.
Risks and considerations
As with all surgical procedures, there are risks associated with calf release surgery. These are discussed as part of the decision-making process.
The suitability of surgery is assessed on an individual basis.
When to seek specialist advice
If you have persistent symptoms related to calf tightness despite appropriate treatment, specialist assessment can help determine whether calf release surgery may be appropriate.
