Hip Impingement Symptoms and When to See a Specialist
Femoroacetabular impingement is a bony hip mismatch that creates friction during movement, pinching soft tissue; untreated, it damages the labrum and accelerates early osteoarthritis.
Practical reading from Professor Paul Lee and the Lincolnshire Hip Clinic team — across hip replacement, Arthrosamid, ChondroFiller, PRP and the wider world of hip and groin pain.

Femoroacetabular impingement is a bony hip mismatch that creates friction during movement, pinching soft tissue; untreated, it damages the labrum and accelerates early osteoarthritis.

For focal hip cartilage lesions, ChondroFiller injection places collagen to draw the patient's own stem cells into the defect; AMIC performs arthroscopic surgery to drill bone and release the patient's bone-marrow stem cells, then seals the site with a membrane. Each suits different defect sizes and patient fitness.

ChondroFiller, a collagen scaffold, recruits the body's own repair cells to treat focal hip cartilage defects; the scaffold biodegrades within two years, but benefit typically lasts three to five years.

The hip labrum seals the joint and distributes load; when torn, it cannot repair itself because fibrocartilage lacks blood supply, yet physiotherapy can restore function by strengthening surrounding muscles to compensate.

Hip chondral lesions cannot heal: hyaline cartilage lacks blood vessels, so untreated defects tend to enlarge. Treatment strategy depends on grade, size, and the underlying mechanical cause.

ChondroFiller uses a collagen scaffold to recruit the patient's own repair cells for focal cartilage defects; Arthrosamid, a permanent hydrogel, cushions joints ravaged by diffuse osteoarthritis. Each targets a distinct stage of hip joint disease.

A hip labral tear breaches the seal retaining lubricating fluid in the joint, accelerating cartilage wear over months and years.

ChondroFiller™ gels inside focal hip cartilage defects within three to five minutes of injection, triggered by a pH shift at the needle tip, then recruits the body's own repair cells to replace the biodegrading scaffold with endogenous tissue.

ChondroFiller hip injections cost £6,500–£9,500 privately in the UK under a single all-in tariff, but remain unavailable through the NHS despite clinical data supporting their use in focal cartilage defects.
