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.
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.
Hyaluronic acid restores hip joint lubrication; ChondroFiller scaffolds cartilage repair using a collagen gel that self-sets in three to five minutes. These are not interchangeable: HA addresses diffuse osteoarthritis, ChondroFiller targets focal cartilage defects.
Microfracture produces fibrocartilage — scar-like tissue lacking the load-bearing properties of native cartilage — which fails under hip load within 18-36 months; around 62 per cent of repairs fail by four years. AMIC adds a resorbable scaffold that guides the repair toward stronger, hyaline-like cartilage.
