Ankle cartilage repair in Singapore is considered when deep ankle pain, recurrent swelling or a catching sensation persists after an injury, and imaging confirms an osteochondral lesion of the talus. Most cases are done arthroscopically, recovery generally runs three to nine months depending on the technique, and the procedure is Medisave-claimable under the applicable Table of Surgical Procedures classification. The following section outlines patient suitability, the techniques used, what the process and recovery involve, the risks, and what it costs.

Ankle cartilage repair is a group of surgical procedures that restore damaged hyaline cartilage on the talar dome, the top surface of the ankle bone. The aim is to relieve pain, improve joint function, and slow progression towards ankle arthritis.
The talar dome is the usual site of osteochondral lesions of the talus (OLTs), where both the cartilage surface and the bone beneath it are damaged. Hyaline cartilage has a very limited blood supply and cannot heal the way a muscle or ligament does. Published reviews of osteochondral lesions of the talus describe a lesion that tends to persist or deteriorate rather than resolve once the cartilage surface is breached.
The joint itself also shapes what is surgically possible. The ankle mortise, the tight bony socket formed by the tibia and fibula around the talus, is far more confined than the knee. That restricts access and influences which techniques can realistically be used.
Not every osteochondral lesion needs surgery. Most patients present with chronic deep ankle pain that has outlasted the original injury, swelling after activity, catching or locking inside the joint, stiffness, or a sense of the ankle giving way. The usual origin is repeated ankle sprains or repetitive impact loading, and chronic ligament laxity is a recognised pathway to secondary cartilage damage because abnormal joint movement gradually wears the talar surface.
For smaller lesions or milder symptoms, non-surgical management is the appropriate starting point:
Surgery is considered when symptoms persist despite three to six months of structured conservative care, or when mechanical symptoms (such as joint locking) restrict daily function. Lesion size, depth, and subchondral bone involvement on MRI help determine surgical suitability. Diffuse ankle osteoarthritis, poor subchondral bone stock, active smoking, and elevated BMI can impair healing and affect procedure durability.
In cases of advanced joint degeneration where cartilage repair is no longer clinically indicated, joint fusion or total ankle replacement may be discussed as alternative surgical options.
Technique selection depends on lesion size, depth, location on the talar dome, the degree of bone involvement, and the patient’s activity level. Treatment protocol selection varies on an individual basis. Guidance on managing talar osteochondral lesions explains how these variables map onto each procedure.
|
Technique |
Approach |
Generally Used For |
Key Consideration |
| Microfracture | Arthroscopic | Lesions under 1.5 cm² without significant bone loss | Produces fibrocartilage rather than hyaline cartilage; results may decline after 3 to 5 years |
| OATS (osteochondral autograft transfer) | Arthroscopic or open | Contained defects with bone involvement | Graft harvested from the patient’s own knee; donor site discomfort possible |
| ACI or MACI (autologous chondrocyte implantation) | Open or arthroscopic-assisted | Larger lesions over 1.5 to 2 cm² | Two-stage procedure; cells cultured in a laboratory before implantation |
| Scaffold-based repair | Arthroscopic or open | Lesions requiring structural support during healing | Used selectively; long-term data still accumulating |
Marrow stimulation remains the most common first-line approach for small lesions. A lesion that looks straightforward on MRI can reveal additional complexity once the joint is inspected, so the final technique is sometimes confirmed intra-operatively.
The surgeon accesses the talar dome, removes the damaged tissue, prepares the underlying bone bed, and then either stimulates the body to produce new repair tissue or transplants healthy cartilage, bone or cultured cells into the defect. From first consultation to full recovery, the pathway typically spans six to twelve months.
The procedure is performed under general or regional anaesthesia, usually as day surgery or a one-night admission.
Recovery generally runs three to nine months for daily activities, with return to sport often taking nine to twelve months. Progression is milestone-driven rather than calendar-driven, and the technique used has a substantial bearing on the early phase.
Patients in sedentary occupations may return within two to four weeks. Physical or standing roles typically need six to twelve weeks. The structure of the programme matters as much as its length.
Physical rehabilitation and non-weight-bearing periods are planned on an individual, milestone-driven basis. Structured timelines and care expectations are reviewed with each patient during pre-operative evaluation.
The intended benefits of treating a talar cartilage lesion, rather than leaving it, may include:
Regarding procedure longevity, current reviews of ankle cartilage repair report that microfracture results can decline after three to five years in some patients, particularly those with larger lesions or high physical demands, because fibrocartilage is biomechanically less resilient than native hyaline cartilage. OATS and cell-based repairs are generally reserved for larger or deeper lesions where fibrocartilage alone is expected to be less durable, though long-term survival data comparing techniques directly remains mixed and individual outcomes vary.
Surgical intervention involves potential risks that require pre-operative clinical discussion.
These risks are reduced, though not eliminated, through careful patient selection, appropriate technique choice and structured post-operative rehabilitation. Individual patient risk factors are evaluated during clinical assessment.
Costs vary with technique, lesion complexity, hospital setting and length of stay. Most arthroscopic cartilage procedures on the talus fall under Table of Surgical Procedures code SB705A, Ankle Therapeutic Arthroscopy (TOSP Table 4A). According to the published bill information, transacted bills for 2023 were as follows.
| Setting | Ward Type | Typical Bill | Typical Bill Range |
| Public hospital, day surgery | Subsidised | SGD2,546 | SGD1,751 to SGD4,004 |
| Public hospital, inpatient | Ward B2 | SGD3,099 | SGD1,930 to SGD4,884 |
| Public hospital, inpatient | Ward C | SGD3,491 | SGD2,804 to SGD4,815 |
| Private hospital, inpatient | Inpatient | SGD27,033 | SGD16,597 to SGD28,587 |
Figures are median transacted bills inclusive of GST, before MediSave and insurance payouts. For private settings, published government fee benchmarks for this code are also available: SGD5,886 to SGD10,464 for the surgeon fee and SGD1,308 to SGD1,744 for the anaesthetist fee, both inclusive of GST.
Factors that influence where a given case sits within these figures:
An itemised estimate can be requested during the pre-operative consultation.
Ankle cartilage repair addresses a focal osteochondral lesion of the talus that has not settled with a properly completed course of physiotherapy, bracing and activity modification. The technique is chosen case by case according to lesion size, depth and bone involvement. Rehabilitation progression is milestone-driven rather than time-bound, and requires comprehensive pre-operative preparation for post-surgical mobility limitations.
If deep ankle pain, swelling or catching has persisted months after an injury, an assessment with a foot and ankle specialist can establish whether a cartilage lesion is the cause and whether ankle cartilage repair in Singapore is a reasonable next step. Diagnostic imaging and a detailed patient functional history guide clinical decision-making.

Hyaline cartilage has a very limited blood supply and little capacity for self-repair once damaged. Without intervention, an osteochondral lesion of the talus tends to persist or worsen over time rather than resolve.
Recovery generally takes three to nine months for most daily activities, with return to sport often requiring up to twelve months. The non-weight-bearing phase alone runs six to twelve weeks depending on technique, and physiotherapy continues throughout.
Arthroscopic cartilage procedures on the talus generally fall under TOSP code SB705A and are Medisave-claimable subject to the prevailing withdrawal limits. MediShield Life and Integrated Shield Plans may provide further coverage, depending on specific policy terms and ward selection.
Microfracture is a marrow stimulation technique that creates small perforations in the bone beneath the lesion to prompt new tissue growth. It suits smaller lesions under 1.5 cm² and produces fibrocartilage rather than true hyaline cartilage. OATS transplants a plug of healthy cartilage and bone from elsewhere in the patient’s joint into the defect, and is generally used for contained lesions with bone involvement where a more structurally durable repair is needed.
Yes. Most patients are non-weight-bearing for six to twelve weeks depending on the technique used, so crutches or a knee scooter should be arranged before the day of surgery rather than afterwards.
If deep ankle pain, swelling, or mechanical catching persists for more than three months following an injury, an orthopaedic evaluation with diagnostic imaging (MRI) can help determine if a cartilage lesion is present.
