Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Current treatment strategies-selected according to lesion size, location, and patient characteristics-range from conservative modalities (weight-bearing restriction, NSAIDs, immobilization) to arthroscopic debridement, bone marrow-stimulating techniques such as microfracture or nanofracture combined with biologic scaffolds, autologous chondrocyte-based procedures (ACI, MACI, AMIC), autologous osteochondral transfers (mosaicplasty/OAT), and more recently, biologic augmentations with platelet-rich plasma (PRP) or bone marrow aspirate concentrate (BMAC).
The microfracture technique is usually performed arthroscopically. Perforation of the subchondral plate recruits mesenchymal stem cells that drive cartilage repair. Concomitant use of a biologic scaffold has been shown to enhance cartilage regeneration and improve functional scores. While microfracture provides an initial stimulus for defect filling, biologic cartilage scaffolds support cell adhesion and foster the formation of hyaline-like tissue. Autologous osteochondral transfers are preferred for larger lesions, and among autologous chondrocyte-based techniques, no meaningful short-term clinical differences have been demonstrated.
Plantar pressure analysis (pedobarography) yields objective information on foot and ankle biomechanics during gait and is widely used to detect changes after orthopedic surgery. By quantifying plantar pressure distribution, pedobarography enables detailed assessment of foot and ankle loading patterns. In patients with talar OCD, gait analyses have shown that the ankle tends to assume a valgus position during walking; medial talar lesions are associated with reduced plantarflexion at the Lisfranc joint, whereas lateral talar lesions demonstrate increased midfoot peak pressure.
This study will evaluate postoperative changes in gait biomechanics-measured by pedobarography-in patients with talar OCD treated arthroscopically with microfracture and a biologic cartilage scaffold. We hypothesize that the abnormal plantar pressure distribution observed preoperatively will normalize after surgery, bringing gait biomechanics closer to those of healthy individuals.

Microfracture + Biologic Scaffold
arthroscopic microfracture and biological scaffold implementation for osteochondral defects of talus
All enrolled patients will undergo a standardized single-stage arthroscopic procedure under spinal or general anesthesia with the patient supine and the ankle placed in appropriated position. Standard anteromedial and anterolateral portals are established. The talar osteochondral defect is inspected, measured, and any unstable cartilage is sharply débrided to create stable vertical walls, exposing healthy subchondral bone. Using a 1.0- to 1.2-mm awl, multiple perforations are made perpendicular to the lesion base, 3-4 mm apart and \~2-4 mm deep, until uniform "marrow fat-bleeding" is observed-mobilizing mesenchymal stem cells .A sterile, resorbable, type-I/III collagen bilayer scaffold is trimmed to the exact defect footprint using a template fashioned intra-operatively.
