Articular Cartilage Lesions

Background. Articular cartilage lesions of the talus remain a challenging clinical problem because of the lack of natural regeneration and limited treatment options. Microfracture is often the first-line therapy, however lesions larger than 1.5 cm2 have been shown to not do as well with this treatment method. Methods. The objective of this retrospective study was to evaluate the outcomes of iliac crest bone marrow aspirate concentrate/collagen scaffold (ICBMA) and particulated juvenile articular cartilage (PJAC) for larger articular cartilage lesions of the talus. Fifteen patients undergoing ICBMA or PJAC for articular cartilage lesions of the talus from 2010 to 2013 were reviewed. Twelve patients, 6 from each treatment option, were included in the study. American Orthopaedic Foot and Ankle Surgeons (AOFAS), Foot and Ankle Ability Measure (FAAM), and Short Form–12 (SF-12) outcome scores were collected for each patient. Results. The mean age was 34.7 ± 14.8 years for ICBMA and 31.5 ± 7.4 years for PJAC. Lesion size was 2.0 ± 1.1 cm2 for ICBMA and 1.9 ± 0.9 cm2 for PJAC. At a mean follow-up of 25.7 months (range, 12-42 months), the mean AOFAS score was 71.33 for ICBMA and 95.83 for PJAC (  P = .019). The FAAM activities of daily living subscale mean was 77.77 for ICBMA and 97.02 for PJAC (   P = .027). The mean FAAM sports subscale was 45.14 for ICBMA and 86.31 for PJAC (  P = .054). The SF-12 physical health mean was 47.58 for ICBMA and 53.98 for PJAC (  P = .315). The SF-12 mental health mean was 53.25 for ICBMA and 57.8 for PJAC (  P = .315). One patient in treated initially with ICBMA underwent revision fixation for nonunion of their medial malleolar osteotomy, which ultimately resulted in removal of hardware and tibiotalar arthrodesis at 2 years from the index procedure. Conclusion. In the present analysis, PJAC yields better clinical outcomes at 2 years when compared with ICBMA for articular cartilage lesions of the talus that were on average greater than 1.5cm2.

Category: Arthroscopy Introduction/Purpose: With reported incidence rates ranging from 40% to 70% post ankle sprains and fractures, osteochondral lesions of the talus (OLT) are not uncommon. However, management of such defects remains challenging. Microfracturing is considered the standard treatment for symptomatic OLTs.Larger lesions however typically require more invasive restorative procedures such as autologous osteochondral transplantation. Microfracture results are variable due to the fact that the resulting reparative fibrocartilage is weaker and biomechanically inferior to native hyaline cartilage. In this study, we examine the functional and radiological outcomes following use of a new arthroscopic technique utilizing a mixture of micronized allograft cartilage matrix (BioCartilage) (Arthrex, Naples, FL) soaked in Bone Marrow Aspirate Concentrate (BMAC) to fill OLTs. Methods: Eighty-six consecutive patients treated for OLT using arthroscopic debridement and BioCartilage matrix soaked in BMAC were identified. All patients were treated by a single fellowship-trained sports medicine and foot and ankle surgeon. Functional outcomes were assessed using the Foot and Ankle Outcome Score (FAOS) and Patient-Reported Outcomes Measurement Information System (PROMIS). This information was obtained from a prospective registry at the authors’ institution. Wilcoxon signed rank tests were used to determine statistical significance between pre and postoperative clinical scores. Additionally, an attending radiologist assessed the reparative cartilage morphology on postoperative MRI scans. This was evaluated and scored using a modified magnetic resonance observation of cartilage tissue (MOCART) scoring system. Results: Thirty-one patients (19 Females; 12 Males) with a mean age of 37.8 years (Range 15–54) had a minimum follow-up duration of 12 months and were thus included in this review. Mean follow-up duration was 15.8 months (Range 12 –25.7). The mean patient BMI was 27.4 (Range 19.6 – 39.4), while the average osteochondral lesion size was 85.9 mm2 (Range 35 – 220). The Physical Function domain of the PROMIS score, demonstrated statistically significant change, improving from 40.63 ±8.31 to 48.31 ±10.07 (p=0.02). The Pain Intensity domain also improved significantly from 49.06 ±9.32 to 42.14 ±9.38 (p=0.03). The Pain Interference domain and FAOS scores did improve but not reaching statistical significance. The mean MRI MOCART score was 69 ±13.34 with 13.3 months average follow-up duration. Conclusion: Achieving the longest duration possible of symptom-free functioning postoperatively is the main goal of any cartilage repair procedure. Augmentation of an articular lesion’s infill with BioCartilage and BMAC may help enhance the biomechanical properties of the reparative fibrocartilage construct and its longevity. Our initial findings demonstrate favorable patient-reported outcomes. Moreover, postoperative MRIs demonstrate the majority of the lesions showed either complete or hypertrophic infill, complete or hypertrophic integration, homogenous repair tissue, and isointense signals. Long-term studies prospectively assessing the effectiveness of this technique in maintaining pain-free-function of the ankle joint are warranted.

Objectives: Osteochondritis dissecans (OCD) is an idiopathic alteration of the subchondral bone which may lead to early osteoarthritis. This condition is commonly seen in the knee and is more common in young, athletic individuals. Several techniques have been developed to address the variable presentation of OCD in the knee, each with varying results. To our knowledge the use of autogenous bone marrow supplementation to an OCD lesion has not been described. The purpose of this study was to determine the radiographic healing of OCD lesions of the knee in a cohort of young, active patients who underwent retroarticular drilling of an OCD lesion with supplemental back-filling with bone marrow aspirate concentrate as an adjuvant to facilitate healing. Methods: We evaluated adolescent patients who were diagnosed with OCD of the knee who had previously failed non-operative, conservative treatment. All subjects underwent retroarticular drilling of the knee with supplemental back-filling of the lesion with bone marrow aspirate concentrate (BMAC®), harvested from the ilium, by two Orthopaedic Surgeons from a single institution. Based off previously published definitions, lesions were assigned as small if < 320 mm2 or large >320 mm2. All lesions were then followed radiographically for evidence of healing. Healing was graded based off the ROCK (Research in OsteoChondritis of the Knee) group radiographic healing criteria, which has shown excellent reliability. The healing was rated by two independent reviewers and when disagreements were noted a third reviewer was brought in to facilitate group consensus on healing. Results: 52 lesions in 49 patients were included in the study. 26 right knees, 26 left knees with 41 lesions located on the medial femoral condyle and 11 lesions located on the lateral femoral condyle. The mean age of the subjects was 12.5 (10 - 17) years old. 30 subjects were male, 19 were female. All lesions were categorized as immobile lesions based off the ROCK Arthroscopy Classification. The average OCD lesion size was 407 mm2 (132 - 899 mm2), respectively. The mean amount of BMAC® used per OCD lesion was 60 mL (45 - 120 mL). 40 lesions (76.9%) were rated as healed at a mean of 10.6 (2 - 32) months. 10 lesions (18.9%) were rated as 25-75% healed and 3.8% were rated at 0 - 25% healed at latest follow-up. 76.5% of large lesions were rated as healed at final follow-up. Whereas 77.8% of small lesions were rated as healed at final follow-up. There were three complications (1 rash from skin glue, 1 suture abscess, and 1 contact dermatitis from surgical cleansing prep) however no complications were noted from the surgical intervention or BMAC®. Conclusion: Overall healing rates with surgical treatment of OCD lesions that have failed non-operative interventions are variable. For immobile lesions, mainstay treatment options include retroarticular and transarticular drilling. Based off previous definitions of lesion size, the mean lesion size in our cohort would be categorized as “large” with 65% of our lesions falling into this category. Previously published series have shown that large lesions are significantly less likely to heal. Despite this we showed a 76.5% healing rate for large lesions. Overall, the adjuvant supplementation of BMAC® as back-fill for retrograde drilling of large OCD lesions of the knee has shown excellent results with no serious complications associated with its use. Future randomized trials are necessary to evaluate the comparative effectiveness of this treatment method.

Time Point

Background: The treatment of osteochondral lesions of the talus (OLTs) with a juvenile cartilage allograft is a relatively new procedure. Although other treatment options exist for large OLTs, the potential advantage of a particulated juvenile allograft is the ability to perform the procedure arthroscopically or through a minimal approach. No previous studies have looked at the results of an arthroscopic approach, nor have any compared an arthroscopic technique with an open approach. Purpose: To compare the outcomes of an arthroscopic transfer technique with the previously published open technique. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 34 patients (mean age, 33 years) underwent treatment of talar cartilage lesions with a DeNovo NT Natural Tissue Graft. Of these treatments, 20 were performed arthroscopically and 14 were performed with open arthrotomy. There was no statistically significant difference between the groups with respect to age, lesion width, lesion depth, lesion length, or operative time. The mean lesion area was 107 mm2. The scores from 6 different validated outcome measures were recorded for patients in each group preoperatively and subsequently at 6 months, 1 year, 18 months, and 2 years. Results: Comparing outcome scores at each time point to baseline, there were no statistically significant postoperative differences found between open and arthroscopic approaches with regard to the visual analog scale (VAS) for pain ( P = .09), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale ( P = .17), Foot and Ankle Ability Measure (FAAM)–sports subscale ( P = .73), Short Form–12 (SF-12) physical health summary ( P = .85), SF-12 mental health summary ( P = .91), or FAAM–activities of daily living subscale ( P = .76). Conclusion: The treatment of talar articular cartilage lesions with a DeNovo NT Natural Tissue Graft demonstrated no significant differences in outcome at 2 years regardless of whether the graft was inserted with an arthroscopic or open technique. Clinical Relevance: Our analysis demonstrated no significant difference between an arthroscopic versus open approach at any time point for the first 2 years after implantation of a juvenile particulated cartilage allograft for large OLTs. With that said, both groups demonstrated improvement from baseline. These findings indicate that surgeons with different levels of comfort utilizing arthroscopic techniques can offer this treatment modality to their patients without altering their planned surgical approach. In addition, this will be particularly helpful in counseling patients for surgery when the extent of the defect will be evaluated intraoperatively. Patients can be counseled that they will likely have the same incisions regardless of whether they require debridement, microfracture, or implantation of a particulated allograft.

Background: Articular cartilage lacks the ability for intrinsic repair after acute injury, and focal articular cartilage lesions cause significant morbidity worldwide. Arthroscopic debridement (chondroplasty) represents the majority of cartilage procedures of the knee; however, limited data exist regarding outcomes after chondroplasty performed in isolation of concurrent procedures or not as a primary treatment for osteoarthritis (OA). Hypothesis: Arthroscopic mechanical chondroplasty is beneficial for patients with a focal cartilage lesion of the knee in the absence of meniscal pathology or OA. Study Design: Case series; Level of evidence, 4. Methods: Potential participants were identified by querying billing data from a 3-year period in a single-surgeon practice, and eligible patients were verified to meet inclusion criteria through electronic medical record review. OA was quantified through Kellgren-Lawrence (KL) scoring. Subjective patient-reported outcome (PRO) scores, including International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Tegner, Lysholm, and Veterans RAND 12-Item Health Survey (VR-12), were collected preoperatively and at follow-up intervals. International Cartilage Repair Society (ICRS) grade and lesion size were determined at arthroscopy. Linear regression was used to determine the effect of baseline score on final follow-up score. Correlated regression equations were used to assess the relationship of covariates and change in PRO scores. Results: Fifty-three of 86 (62%) eligible participants completed postoperative questionnaires at an average of 31.5 months (range, 11.5-57 months). The mean patient age was 37.3 ± 9.7 years and mean body mass index (BMI) was 27.7 ± 5.6 kg/m2; 33 (62%) participants were women. The mean treated lesion size was 3.3 ± 1.9 cm2, of these, 36 (68%) were ICRS grade 2 or 3, and 42 (79%) patients had a KL score of 0 to −2. On average, the cohort demonstrated significant improvement from baseline for almost all PRO scores. Regression analysis of change in score versus baseline indicated participants with lower preoperative scores gained more benefit from chondroplasty. Correlated regression equations showed KL score >0 and male sex had a consistent positive effect on change in PRO scores, high ICRS grade had a consistent negative effect, and lesion size, age, and obesity had no effect. Eight patients (15%) required further surgical intervention within the follow-up period. Conclusion: The clinical efficacy of chondroplasty for repair of focal cartilage defects of the knee has not been studied in isolation from concurrent orthopaedic procedures. Our data show that arthroscopic mechanical chondroplasty is beneficial to patients, and response to surgical intervention is correlated with baseline PRO scores, sex, ICRS grade, and KL score.

Bone marrow aspirate concentrate (BMAC) is now commonly used in orthopedic surgery. Animal studies showed promising results for cartilage, bone, and soft tissue healing; however, many of these outcomes have yet to be translated to human models. While there has been an increase in the use of BMAC in foot and ankle procedures, the associated clinical evidence is limited. The purpose of this review is to analyze the existing literature in order to evaluate the safety and efficacy of BMAC in foot and ankle surgery.

AbstractRestoration and repair of articular cartilage injuries remain a challenge for orthopaedic surgeons. The standard first-line treatment of articular cartilage lesions is marrow stimulation; however, this procedure can often result in the generation of fibrous repair cartilage rather than the biomechanically superior hyaline cartilage. Marrow stimulation is also often limited to smaller lesions, less than 2 cm2. Larger lesions may require implantation of a fresh osteochondal allograft, though a short shelf life, size-matched donor requirements, potential challenges of bone healing, limited availability, and the relatively high price limit the wide use of this therapeutic approach. We present a straightforward, single-stage surgical technique of a novel reparative and restorative approach for articular cartilage repair with the implantation of a cryopreserved viable osteochondral allograft (CVOCA). The CVOCA contains full-thickness articular cartilage and a thin layer of subchondral bone, and maintains the intact native cartilage architecture with viable chondrocytes, growth factors, and extracellular matrix proteins to promote articular cartilage repair. We report the results of a retrospective case series of three patients who presented with articular cartilage lesions more than 2 cm2 and were treated with the CVOCA using the presented surgical technique. Patients were followed up to 2 years after implantation of the CVOCA and all three patients had satisfactory outcomes without adverse events. Controlled randomized studies are suggested for evaluation of CVOCA efficacy, safety, and long-term outcomes.

Harvest Site

Background Autologous bone graft is the gold standard in orthopedics, with the iliac crest the most common harvest site. In an attempt to minimize morbidity with open bone graft harvest from the iliac crest and still maintain the benefit of collecting and transplanting live cells and growth factors, bone marrow aspirate concentrate (BMAC) from the iliac crest has become increasingly popular. However, any harvest procedure can potentially cause pain and complications. The purpose of this study was to evaluate the safety and complications of BMAC from the iliac crest for use in foot and ankle fusion procedures. Methods A retrospective chart review was performed on all patients who underwent BMAC harvest from the iliac crest with their foot or ankle procedure by 1 of 4 fellowship-trained surgeons (2014-2017) with a minimum of 6-month follow-up. Patients were evaluated for complications, pain, and functional limitation secondary to the harvest. The final outcome follow-up was conducted using a specifically designed telephone questionnaire to assess patient satisfaction. A total of 55 patients were included, with a median age of 58 years (range 31-81 years) and 69% were women. Results Out of 55 patients, 52 (94.5%) reported good to excellent results, and satisfaction with the procedure at the time of the questionnaire. Three patients reported persistent complications and some element of dissatisfaction after 6 months. Some patients reported transient complications (hematomas and numbness) that eventually resolved. Fifty percent of patients reported some element of immediate post-operative pain. However, at the time of final follow-up, only 2 reported persistent pain at the harvest site lasting up to 6 months, but it was not activity limiting. Conclusion BMAC harvest is a safe procedure with a high rate of patient satisfaction and minimal morbidity. Levels of Evidence Level IV: Case series
