Medial Femoral Condyle Free Flap: A Systematic Review and Proportional Meta-analysis of Applications and Surgical Outcomes. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5708. [PMID: 38596574 PMCID: PMC11000773 DOI: 10.1097/gox.0000000000005708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 02/12/2024] [Indexed: 04/11/2024]
Abstract
Background Recalcitrant bone nonunion and osseous defect treatment is challenging and often requires vascularized bone transfer. The medial femoral condyle flap has become an increasingly popular option for reconstruction. The study aims at reviewing its different applications and synthesizing its surgical outcomes. Method A systematic review including all studies assessing surgical outcomes of free medial femoral condyle flap for bone reconstruction in adults was conducted on January 31, 2023. Flap failure and postoperative complications were synthesized with a proportional meta-analysis. Results Forty articles describing bony reconstruction in the head and neck, upper limb, and lower limb areas were selected. Indications ranged from bony nonunion and bone defects to avascular bone necrosis. Multiple flaps were raised as either pure periosteal, cortico-periosteal, cortico-cancellous-periosteal, or cortico-chondro-periosteal. A minority of composite flaps were reported. Overall failure rate was 1% [95% confidence interval (CI), 0.00-0.08] in head & neck applications, 4% in the lower limb (95% CI, 0.00-0.16), 2% in the upper limb (95% CI, 0.00-0.06), and 1% in articles analyzing various locations simultaneously (95% CI, 0.00-0.04). Overall donor site complication rate was 4% (95% CI, 0.01-0.06). Major reported complications were: femoral fractures (n = 3), superficial femoral artery injury (n = 1), medial collateral ligament injury (n = 1), and septic shock due to pace-maker colonization (n = 1). Conclusion The medial femoral condyle flap is a versatile option for bone reconstruction with high success rates and low donor site morbidity.

A chimeric medial femoral condyle chondro-osseus flap with two thin periosteal flaps to reconstruct partial necrosis of talar body: A case report. Microsurgery 2024; 44:e31127. [PMID: 37937805 DOI: 10.1002/micr.31127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 09/20/2023] [Accepted: 10/07/2023] [Indexed: 11/09/2023]
Abstract
Total talar extrusion is a rare complication of high-energy traumas. A consequence of this injury can be avascular necrosis (AVN) of the talus. Patients are confronted with pain, limited range of motion and post-traumatic arthritis. As AVN progresses the talus is gradually destroyed. This report presents the use of a chimeric medial femoral condyle chondro-osseus flap with two thin periosteal flaps to increase vascular supply to the traumatized area, accelerate bone formation, flap integration, and restore articular surfaces in a patient with partial necrosis of talar body. The patient was a 26-year-old female with open left lateral talar extrusion after a motor-vehicle accident that developed a partial avascular necrosis, at the level of the subtalar and ankle joint with altered talar dome surface with partial depression of 2 cm. The patient was in pain and not able to walk. The medial femoral condyle chondro-osseus portion was placed in the talar dome depression to restore the subtalar joint, the periosteal flaps were placed on top to reconstruct the ankle joint restoring the articular surfaces and the correct weight-bearing distribution. No complications or morbidity of donor site were observed. One year after the operation, the patient walks free, without pain. Post-operatory x-ray performed, evidenced progressive bone healing and reduction of the AVN. In the intent of performing a joint-saving procedure, the presented chimeric flap might be effective in the short-term with excellent clinical and radiographic outcomes.

The Frequency and Severity of Complications in Surgical Treatment of Osteochondral Lesions of the Talus: A Systematic Review and Meta-Analysis of 6,962 Lesions. Cartilage 2023; 14:180-197. [PMID: 37144397 PMCID: PMC10416205 DOI: 10.1177/19476035231154746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 01/18/2023] [Accepted: 01/18/2023] [Indexed: 05/06/2023] Open
Abstract
OBJECTIVE The primary aim was to determine and compare the complication rate of different surgical treatment options for osteochondral lesions of the talus (OLTs). The secondary aim was to analyze and compare the severity and types of complications. DESIGN A literature search was performed in MEDLINE (PubMed), EMBASE (Ovid), and the Cochrane Library. Methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS). Primary outcome was the complication rate per surgical treatment option. Secondary outcomes included the severity (using the Modified Clavien-Dindo-Sink Complication Classification System for Orthopedic Surgery) and types of complications. The primary outcome, the severity, and the sub-analyses were analyzed using a random effects model. A moderator test for subgroup-analysis was used to determine differences. The types of complications were presented as rates. RESULTS In all, 178 articles from the literature search were included for analysis, comprising 6,962 OLTs with a pooled mean age of 35.5 years and follow-up of 46.3 months. Methodological quality was fair. The overall complication rate was 5% (4%-6%; treatment group effect, P = 0.0015). Analysis resulted in rates from 3% (2%-4%) for matrix-assisted bone marrow stimulation to 15% (5%-35%) for metal implants. Nerve injury was the most observed complication. CONCLUSIONS In 1 out of 20 patients treated surgically for an OLT, a complication occurs. Metal implants have a significantly higher complication rate compared with other treatment modalities. No life-threatening complications were reported.

Abstract
PURPOSE The purpose of this study was to explore the feasibility and evaluate the clinical outcomes of treatment for phalangeal and metacarpal segmental defects with the induced membrane technique and autologous structural bone grafting. METHODS Sixteen patients who sustained phalangeal or metacarpal bone segmental defects were treated by the induced membrane technique and autologous structural bone grafting from June 2020 to June 2021 at our center. RESULTS The average follow-up was 24 weeks (range, 12-40 weeks). Radiography demonstrated union of all bone grafts after an average of 8.6 weeks (range, 8-12 weeks). All incisions at donor and recipient sites demonstrated primary heal without infection complications. The mean visual analog scale score of the donor site was 1.8 (range, 0-5), with a good score in 13 cases and a fair score in 3. The mean total active motion of the fingers was 179.9°. CONCLUSIONS The feasibility of the induced membrane technique and structural treatment with a cylindrical bone graft for segmental bone defects of the metacarpal or phalanx is demonstrated by follow-up radiography results. The bone graft provided much more stability and structural support in the bone defects, and the bone healing time and bone union rate were ideal.

Abstract
Background Ankle hemiarthroplasty is a 1-piece implant system replacing the talar side of the tibiotalar joint. Hemiarthroplasty offers limited bone resection and may provide easier revision options than joint-ablating procedures. Methods Prospective, multicenter, noncomparative, nonrandomized clinical study with short term follow-up on patients undergoing hemiarthroplasty of the ankle. Radiologic and functional outcomes (Foot and Ankle Outcome Score FAOS, Foot and Ankle Ability Measure [FAAM], Short Form-36 Health Survey [SF-36], Short Musculoskeletal Functional Assessment [SMFA], and visual analog scale [VAS] pain scores) were obtained at 3 and 12 months and the last follow-up (mean 31.9 months). Results Ten patients met the inclusion criteria. Three were converted to total ankle replacement at 14, 16, and 18 months. Pain VAS scores improved on average from 6.8 to 4.8 (P = .044) of the remaining 7 at a mean of 31.9 months' follow-up. For these 7 in the Survival Group, we found that SF-36 physical health component improved from 25.03 to 42.25 (P = .030), SMFA dysfunction and bother indexes improved from 46.36 to 32.28 (P = .001), and from 55.21 to 30.14 (P = .002) in the Survival Group, and FAAM sports improved from 12.5 to 34.5 (P = .023). Conclusion Patients undergoing hemiarthroplasty of the ankle joint for talar-sided lesions had a 30% failure rate by 18 months. Those who did not have an early failure exhibited modest pain reduction, functional improvements, and better quality of life in short-term follow-up. This procedure offers a possible alternative for isolated talar ankle cartilage cases. Level of Evidence Level IV, prospective case series.

Abstract
BACKGROUND Osteochondral lesions of the talus (OLT) are defects affecting the articular cartilage as well as the subchondral bone, on the lateral shoulder possibly associated with trauma. This study presents the results of reconstructing OLT using vascularized osteochondral flaps from the femoral trochlea. METHODS We treated 19 patients with osteochondral talar shoulder defects, using osteochondral flaps from the medial (MFT) or lateral (LFT) femoral trochlea. Functional outcome was evaluated by clinical investigation, visual analogue scale (VAS, 0-10), American Orthopaedic Foot and Ankle Society-Ankle and Hindfoot Scale (AOFAS, 0-100) and The Foot and Ankle Disability Index (FADI, 0-104). Radiographic postoperative follow-up was done by anterior-posterior and lateral X-rays and union of the transferred osteochondral flaps was documented by CT scans. RESULTS The osteochondral flaps fused in all of the 19 cases. After a median follow-up of 45.5 months, the patients showed an average FADI of 94.9 and AOFAS-Ankle and Hindfoot Scale of 91.2. All of them were walking free and normal. Subjective median satisfaction was 1.3 in a scale from 1 to 5. CONCLUSION Vascularized transfer of osteochondral flaps from the femoral trochlea is a reliable treatment option for symptomatic OLT of the medial and lateral talar edge. LEVEL OF CLINICAL EVIDENCE Therapeutic IV.

We present a case report of a man in his 20s with osteochondritis dissecans of the talus, treated with autologous transplantation of a vascularised osteochondral flap. The patient with high level of activity presented to our orthopaedic outpatient department for progressive limping and pain, mainly related to sports. An osteochondritis dissecans grade IV of the medial talus was identified by MRI. A microvascular transfer of osteochondral tissue was performed successfully. At follow-up 1 year after surgery, the MRI examination revealed vital cartilage; the patient was free of pain and had returned to his previous level of activity.

Abstract
BACKGROUND There has been no consensus regarding the treatment of osteochondral lesions of the talus, there has been many attempts to formulate a treatment pathway, with multiple proposed modalities and adjuncts used. OBJECTIVES The aim of this paper was to investigate the evidence published in the recent history, identify the relevant papers, review and summarize the findings, to help clarify the available operative treatment options and their respective efficacies based on the level of evidence provided. STUDY DESIGN & METHODS A literature search through electronic databases MEDLINE and EMBASE was done, these databases were screened for publications and papers form June 2004 to June 2019. Key words were utilised in the search 'talus, talar, tibia, cartilage, osteochondral, ankle, osteochondritis dissecans, articular cartilage'. Studies on adults aged 18-60 years were included. Exclusion criteria were studies with less than 10 patients, or no clear outcome was recorded. Papers were reviewed by the authors and data extracted as per a pre-defined proforma. RESULTS Following screening, 28 published articles were included and reviewed. Of these publications 5 were level I, 7 level II, 4 level III and 12 level IV. The total number of patients was 1061 patients. Treatment modalities included arthroscopic microfracture, drilling, hyaluronic acid injection, platelet rich plasma, osteochondral autologous transplantation (OAT), vascularised free bone graft among others. The most common functional measures used to assess efficacy were the Visual analogue scale (VAS) and the American Orthopaedic Foot and Ankle (AOFAS) score. Follow up ranged from 26 weeks upto 4 years. CONCLUSIONS Despite the abundance of treatment options, high level evidence (level I) remains limited and does not conclude a definitive treatment modality as superior to others. Further research, in the form highly organised randomised clinical trials, is needed to help improve the efficacy and develop new treatment modalities in the future.

Abstract
The management of symptomatic osteochondral lesions of the talus (OLTs) can be challenging. The number of ways of treating these lesions has increased considerably during the last decade, with published studies often providing conflicting, low-level evidence. This paper aims to present an up-to-date concise overview of the best evidence for the surgical treatment of OLTs. Management options are reviewed based on the size of the lesion and include bone marrow stimulation, bone grafting options, drilling techniques, biological preparations, and resurfacing. Although many of these techniques have shown promising results, there remains little high level evidence, and further large scale prospective studies and systematic reviews will be required to identify the optimal form of treatment for these lesions.

Abstract
BACKGROUND The aim of this study was to evaluate the effectiveness and safety of free corticoperiosteal medial femoral condyle (MFC) flap for ankle, hindfoot and midfoot reconstruction in patients with recalcitrant nonunion. METHODS Patients who underwent ankle and foot reconstruction using the MFC flap at our clinic were recruited for assessment of the union rate, time to union and functional outcome. Furthermore, a clinical and radiological examination of the donor knee was performed using both computed tomography and magnetic resonance imaging. RESULTS Thirteen patients with a mean follow-up time of 2.5 years were included; 10 of them had a previously failed ankle and foot arthrodesis. Union was achieved in 11 patients in an average time of 10 months after MFC flap surgery. Donor site morbidity was minor with no radiological evidence for soft tissue or bone complication. CONCLUSION MFC flaps are a useful and safe reconstructive tool and may be considered after failed ankle and foot arthrodesis.

Abstract
Background: Complex hindfoot pathology may benefit from vascularized bone flap reconstruction rather than traditional bone grafting techniques. Medial femoral condyle (MFC) flaps provide vascularized periosteum, skin, and corticocancellous bone. Methods: A retrospective, single-institution cohort study of consecutive MFC flaps performed for complicated hindfoot reconstruction between 2013 and 2019 was reviewed. Radiologic follow-up assessed osseous union and clinical outcomes were evaluated with the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score. Thirty MFC flaps were performed in 28 patients for complex hindfoot pathology. Twenty-seven flaps had adequate clinical and radiographic follow-up (mean 15.8 months). Results: The majority presented with avascular necrosis (83%) and failed prior operations (67%, mean 3.1). Most hindfoot procedures involved arthrodesis (n = 24, 80%); tibiotalocalcaneal (n = 11) and talonavicular (n = 7) most frequently. Mean osseous flap volume was 10.3 cm3 (range 1.7-18.4 cm3); one flap required takeback for venous congestion but no total flap losses occurred. Primary osseous union was initially achieved in 20 patients (74%, mean 217 days). Six flaps developed interface nonunion; 5 underwent revision arthrodesis and ultimately achieved union in 24/27 flaps (89%, mean 271 days). Risk factors for nonunion were body mass index (BMI) >30 ( P = .017) and prior arthrodesis ( P = .042). Mean AOFAS hindfoot scores increased significantly from 52.3 preoperatively to 70.7 postoperatively ( P < .001). Subscore analysis demonstrated significant improvement in postoperative pain scores from 14.2 to 27.3 out of 40 ( P < .001). Conclusion: The MFC free flap provided vascularized bone for complicated foot and ankle reconstruction with relatively low donor site morbidity, promising osseous union results, and improved functional outcomes. Level of Evidence: Level IV, retrospective case series.

Abstract
BACKGROUND Osteochondral defects (OCDs) of the talus are found subsequent to ankle sprains and ankle fractures. With many surgical treatment strategies available, there is no clear evidence on return-to-sport (RTS) times and rates. PURPOSE To summarize RTS times and rates for talar OCDs treated by different surgical techniques. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS The literature from January 1996 to November 2018 was screened, and identified studies were divided into 7 different surgical treatment groups. The RTS rate, with and without associated levels of activity, and the mean time to RTS were calculated per study. When methodologically possible, a simplified pooling method was used to combine studies within 1 treatment group. Study bias was assessed using the MINORS (Methodological Index for Non-Randomized Studies) scoring system. RESULTS A total of 61 studies including 2347 talar OCDs were included. The methodological quality of the studies was poor. There were 10 retrospective case series (RCSs) that investigated bone marrow stimulation in 339 patients, with a pooled mean rate of RTS at any level of 88% (95% CI, 84%-91%); 2 RCSs investigating internal fixation in 47 patients found a pooled RTS rate of 97% (95% CI, 85%-99%), 5 RCSs in which autograft transplantation was performed in 194 patients found a pooled RTS rate of 90% (95% CI, 86%-94%), and 3 prospective case series on autologous chondrocyte implantation in 39 patients found a pooled RTS rate of 87% (95% CI, 73%-94%). The rate of return to preinjury level of sports was 79% (95% CI, 70%-85%) for 120 patients after bone marrow stimulation, 72% (95% CI, 60%-83%) for 67 patients after autograft transplantation, and 69% (95% CI, 54%-81%) for 39 patients after autologous chondrocyte implantation. The mean time to RTS ranged from 13 to 26 weeks, although no pooling was possible for this outcome measure. CONCLUSION Different surgical treatment options for talar OCDs allow for adequate RTS times and rates. RTS rates decreased when considering patients' return to preinjury levels versus return at any level.

Abstract
Surgical treatment options in a chondroblastoma of the talus breaching the subchondral layer with imminent risk of talar collapse in the weightbearing area are limited. A joint-preserving surgery should be advocated. Because current treatment options such as curettage, cryosurgery, or radiofrequency ablation may not be able to prevent a talar dome breakdown in large defects, nonvascularized bone grafting has been advocated to fill the void. To overcome the lack of vitality, a vascularized bone autograft might be an attractive alternative. We present 3 cases where a large talar defect owing to a chondroblastoma was treated with a vascularized bone autograft. In 1 of the cases, a free microvascular iliac crest bone graft was used, whereas in the other 2 cases, a vascularized graft was harvested from the medial femoral condyle. Computed tomographic scans demonstrated a stable incorporation of the graft in all cases. All patients were highly satisfied with the obtained results and showed a clinical functional outcome similar to the contralateral foot after 36, 60, and 72 months. At the latest radiographic follow-up, no evidence of recurrence was observed. In conclusion, a free vascularized bone autograft can be used to treat a large talar defect owing to chondroblastoma in young patients.

Abstract
BACKGROUND Anterior shoulder instability is a debilitating condition that can require stabilization via a Latarjet procedure. PURPOSE The aim of this study was to characterize the histological composition of the articular-sided surface of the coracoid bone graft after Latarjet procedure. Specific features of cells isolated from the coracoid and graft tissues were assessed. STUDY DESIGN Case series; Level of evidence, 4. METHODS Tissue samples were harvested from 9 consecutive patients undergoing arthroscopic debridement and screw removal after arthroscopic or open Latarjet procedure. Tissues were processed histologically. In 2 patients, the samples were analyzed to assess specific cellular properties. RESULTS Safranin O staining indicated that glenoid tissues contained variable amounts of glycosaminoglycan (GAG) and round chondrocytic cells mainly organized in clusters. Graft tissues contained less GAG and were more cellular but were not organized in clusters and had variable morphological features. An association appeared to exist between the cartilage quality of glenoid tissues and that of the graft tissues. Cells isolated from glenoid and graft tissues exhibited similar proliferation capacity. CONCLUSION The results of our analysis show that cells located at the articular-sided surface of transferred coracoid grafts demonstrate fibrocartilaginous properties and may have the capacity for chondral proliferation. Further studies are needed to confirm this observation and future application.

Abstract
BACKGROUND Vascularized grafts from the femur, including the medial femoral condyle and medial femoral trochlea, are increasingly being used. It is critical to understand the lower extremity complications from flap harvest. METHODS The authors searched available literature reporting on femoral flaps using PubMed, Embase, Cochrane Database, and Web of Science. After article selection, data were collected regarding demographics, procedure details, outcomes, and complications. The authors classified outcomes as good, fair, or poor based on pain, range-of-motion, sensory changes, subjective reporting, patient-reported outcomes, and other donor-site complications, including the need for additional procedures. RESULTS Two hundred twenty articles were identified. Forty-five met criteria for review, with data available for 283 patients. No patients had range-of-motion deficits beyond 1 year. Two percent of patients (six of 283) required additional donor-site procedures, with one report of a femur fracture after medial femoral condyle harvest. Only one study on 45 medial femoral trochlea patients presented patient-reported outcomes regarding the knee. Few objective data were presented. Twenty-eight articles presented adequate complication data for 252 patients to be rated as good, fair, or poor. Overall, 89 percent had good outcomes without donor-site complications. Of the 176 medial femoral condyle patients with outcomes reported, 92 percent had good outcomes; and 71 percent of the 48 medial femoral trochlea patients had good outcomes reported. CONCLUSIONS Overall, the reported donor-site morbidity from medial femoral condyle and medial femoral trochlea harvest is low. Chronic knee pain and sensory changes are most frequently reported, especially in medial femoral trochlea patients.

Abstract
PURPOSE The purpose of this systematic review was to identify the most effective surgical treatment for talar osteochondral defects after failed primary surgery. METHODS A literature search was conducted to find studies published from January 1996 till July 2016 using PubMed (MEDLINE), EMBASE, CDSR, DARE and CENTRAL. Two authors screened the search results separately and conducted quality assessment independently using the Newcastle-Ottawa scale. Weighted success rates were calculated. Studies eligible for pooling were combined. RESULTS Twenty-one studies with a total of 299 patients with 301 talar OCDs that failed primary surgery were investigated. Eight studies were retrospective case series, twelve were prospective case series and there was one randomized controlled trial. Calculated success percentages varied widely and ranged from 17 to 100%. Because of the low level of evidence and the scarce number of patients, no methodologically proper meta-analysis could be performed. A simplified pooling method resulted in a calculated mean success rate of 90% [CI 82-95%] for the osteochondral autograft transfer procedure, 65% [CI 46-81%] for mosaicplasty and 55% [CI 40-70%] for the osteochondral allograft transfer procedure. There was no significant difference between classic autologous chondrocyte implantation (success rate of 59% [CI 39-77%]) and matrix-associated chondrocyte implantation (success rate of 73% [CI 56-85%]). CONCLUSIONS Multiple surgical treatments are used for talar OCDs after primary surgical failure. More invasive methods are administered in comparison with primary treatment. No methodologically proper meta-analysis could be performed because of the low level of evidence and the limited number of patients. It is therefore inappropriate to draw firm conclusions from the collected results. Besides an expected difference in outcome between the autograft transfer procedure and the more extensive procedures of mosaicplasty and the use of an allograft, neither a clear nor a significant difference between treatment options could be demonstrated. The need for sufficiently powered prospective investigations in a randomized comparative clinical setting remains high. This present systematic review can be used in order to inform patients about expected outcome of the different treatment methods used after failed primary surgery. LEVEL OF EVIDENCE IV.

Abstract
Symptomatic osteochondral lesions of the talus remain a challenging problem due to inability for cartilage lesions to heal. Numerous treatment options exist, including nonoperative management, marrow stimulating techniques, and autograft-allograft. Arthroscopic marrow stimulation forms fibrocartilage that has been shown to be biomechanically weaker than hyaline cartilage. Restorative tissue transplantation options are being used more for larger and cystic lesions. Newer biologics and particulated juvenile cartilage are currently under investigation for possible clinical efficacy. This article provides an evidenced-based summary of available literature on the use of biologics for treatment of osteochondral lesions of the talus.

Abstract
Aims This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus. Patients and Methods We reviewed the clinical and radiological outcomes of 27 patients who underwent arthrodesis with either vascularised or non-vascularised (conventional) grafts, comparing the outcomes (clinical scores, proportion with successful union and time to union) between the two groups. The clinical outcome was assessed using the Mazur and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores. The mean follow-up was 35 months (24 to 68). Results The mean outcome scores increased significantly in both groups. In the vascularised graft group, the mean Mazur score improved from 36.9 to 74.6 and the mean AOFAS scale improved from 49.6 to 80.1. In the conventional arthrodesis group, the mean Mazur score improved from 35.5 to 65 and the mean AOFAS scale from 49.2 to 67.6. Complete fusion was achieved in 13 patients (76%) in the vascularised group, but only four (40%) in the conventional group. The clinical outcomes and proportion achieving union were significantly better in the vascularised group compared with the conventional arthrodesis group, although time to union was similar in the two groups. Take home message: Vascularised sliding tibial grafts may be used to achieve arthrodesis in patients with OA of the ankle secondary to osteonecrosis of the talus.
