Incidence of Coexisting Talar and Tibial Osteochondral Lesions Correlates With Patient Age and Lesion Location

Background: The incidence of coexisting osteochondral lesions (OCLs) of the tibia and talus has been negatively correlated with successful clinical outcomes, yet these lesions have not been extensively characterized. Purpose: To determine the incidence of coexisting tibial and talar OCLs, assess the morphologic characteristics of these lesions, and evaluate whether these characteristics are predictive of outcome. Study Design: Case series; Level of evidence, 4. Methods: A total of 83 patients who underwent surgery for a talar OCL were evaluated for coexisting OCLs of the distal tibia with preoperative magnetic resonance images. Size, location, containment, International Cartilage Repair Society (ICRS) grade, patient age, and patient sex were analyzed for predictors of coexisting lesions or patient outcome. The talar and tibial surfaces were each divided into 9 zones, with 1 corresponding to the most anteromedial region and proceeding laterally and then posteriorly. The Foot and Ankle Outcome Score (FAOS) was evaluated pre- and postoperatively. Results: Twenty-six patients (31%) had coexisting tibial and talar OCLs, with 9 (35%) identified as kissing lesions. Age correlated with coexisting lesion incidence, as older patients were more likely to have a coexisting tibial OCL ( P = .038). More than half of talar OCLs were found in zone 4 (61%), whereas the majority of tibial OCLs were located in zones 2, 4, and 5 (19% each). Patients with coexisting lesions were more likely to have a lateral talar OCL ( P = .028), while those without a coexisting tibial lesion were more likely to have a talar OCL in zone 4 ( P = .016). There was no difference in FAOS result or lesion size between patients with and without coexisting OCLs, but patients with coexisting lesions were more likely to have an ICRS grade 4 talar OCL ( P = .034). For patients with coexisting lesions, kissing lesions were more likely to be located in zone 6 ( P = .043). There was no difference in OCL size or containment between kissing and nonkissing coexisting OCLs. Conclusion: The incidence of coexisting talar and tibial OCLs may be more prevalent than what previous reports have suggested, with older patients being more likely to present with this pathology. The location of a talar OCL correlates with the incidence of a coexisting tibial OCL.

Background: In the long-term follow-up after debridement, microfracture, or drilling of osteochondral lesions in the elbow, subsequent osteoarthritis is a problem. Osteochondral transplantation for these defects has become a more common procedure. However, long-term results are unknown. Purpose: This study was undertaken to evaluate long-term clinical and radiologic outcomes of advanced osteochondral lesions in the elbow treated with osteochondral transplantation. Study Design: Case series; Level of evidence, 4. Methods: The study included 8 patients with osteochondral lesions in the elbow who were treated by autologous osteochondral transplantation between 1996 and 2002. Patients (average age, 17 years) were evaluated pre- and postoperatively by Broberg-Morrey score to assess elbow function and by American Shoulder and Elbow Surgeons (ASES) score for pain analysis. In addition, radiographs (at the first postoperative day, and at 5-year and 10-year follow-up) and magnetic resonance images (8 to 12 weeks postoperatively, and at 5-year and 10-year follow-up) were made to evaluate the joint status. At last follow-up (range, 8-14 years postoperatively), 7 of 8 patients were seen for clinical examination and radiologic analysis. Results: The Broberg-Morrey score increased from an average of 75.9 ± 13.1 to 96.4 ± 2.4 and ASES score significantly improved as follows: worst pain, 7.9 ± 1.1 to 1.6 ± 1.9; rest pain, 3.14 ± 2.7 to 0.6 ± 1.5; weight-lifting pain, 7.6 ± 0.8 to 3.1 ± 1.6; and repetitive movement pain, 5.3 ± 2.4 to 1.6 ± 1.5. Compared with the contralateral side, there was a mean preoperative flexion lag of 12.5° ± 11.6°. At the final follow-up, flexion was free. The mean extension lag was reduced from average 5.4° ± 5.7° to 0°. Radiographs of 2 patients made at final follow-up showed mild signs of osteoarthritis (Kellgren and Lawrence grade I). Postoperative magnetic resonance images showed graft viability in all and a congruent chondral surface in 6 of 7 patients. Conclusion: Clinical long-term results after osteochondral transplantation in the elbow are good to excellent and comparable with midterm results in the literature. Therefore, this technique is a reliable option for satisfactory long-term results regarding treatment of advanced osteochondral lesions in the elbow.

Calcaneal Cyst

Background: Since we have frequently noted osseous cyst-like lesions within the calcaneus on MRI studies, we sought to systematically evaluate this finding to determine the incidence and morphologic characteristics on MRI. Methods: Three observers blinded to age evaluated 198 MRIs of the ankle (74 males, 124 females; mean age 47 years, range 13 to 99 years), recording the presence and size of calcaneal cyst-like foci. Statistical analysis was performed to determine if there was an association with age. Additionally, MRI of 12 ankles precontrast and postcontrast were reviewed for the presence of blood vessels in the calcaneus corresponding to the location of the cyst-like lesions and 24 ankle MR arthrograms were reviewed to evaluate communication of the cyst with the adjacent joint. Results: Of the 198 ankle MRI examinations, 81 (40%) had hyperintense foci, all within the mid-calcaneal body. The size ranged from 0.01 cm 2 to 2.47 cm 2 , with a mean size of 0.36 cm 2 (± 0.45 cm 2 ). Thirty-seven (46%) were linear or elongated, whereas 44 (54%) were ovoid or round. Seven of the 81 foci (8.6% or 3.5% of the total population) were 1 cm 2 or larger. There was no significant association of patient age and presence ( p = 0.49) or size ( p = 0.48) of the focus. Location of the cyst-like foci, which often are ovoid or linear, corresponds to penetrating microvessels on precontrast and postcontrast MRI. One MR arthrogram showed communication of a cyst-like focus and the subtalar joint. Conclusions: Calcaneal lesions are relatively common incidental findings on MRI. These lesions appear to represent intraosseous ganglion cysts that arise from the anterior margin of the posterior facet of the subtalar joint in the anatomical neighborhood where vessels penetrate the superior calcaneal cortex. The lesions can vary is size; however, there is no correlation between patient age and lesion size and no significant association between age and presence of these foci.

Background: While smaller talar dome osteochondral lesions (OCLs) are successfully treated with bone marrow stimulation techniques, the optimal treatment for large or cystic OCLs remains controversial. This study tested the hypothesis that transferring structural autograft bone from the distal tibia to the talus for large or cystic OCLs improves pain and function. Methods: Thirty-two patients with large or cystic OCLs underwent structural bone grafting from the ipsilateral distal tibia to the talar dome. Patients were assessed with subjective patient-centered tools and objective clinical outcomes. Average age was 48.6 ± 14.9 years, and average follow-up was 19.5 ± 13.3 months. Average lesion area was 86.2 ± 23.5 mm2, and average depth was 8.4 ± 3.0mm. Results: At final follow-up, improvement compared to preoperative scores was seen in American Orthopaedic Foot & Ankle Society (65.4 ± 21.2 to 86.9 ± 15.0, P < .05), Foot Function Index (48.9 ± 20.8 to 21.1 ± 18.9, P < .05), visual analog scale for pain (4.7 ± 3.0 to 1.4 ± 1.5, P < .05), and Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (40.4 ± 5.4 to 45.5 ± 7.4, P < .05) scores. There was no improvement in PROMIS pain interference (54.7 ± 18.1 to 52.4 ± 7.3, P > .05). Satisfaction with surgery was 8.4 ± 1.3/10, and 96% of patients would have the procedure again. Ninety-four percent of patients returned to work and/or play. One patient had a deep vein thrombosis 6 weeks postoperatively, and 1 patient underwent ankle fusion at 18 months postoperatively. Conclusion: This study demonstrates that structural bone graft harvested from the distal tibia transferred to the talus was a safe and effective treatment for large and cystic OCLs. Outcomes compare favorably to other described techniques for treatment of these injuries. Level of Evidence: Level IV, case series.

Marrow Stimulation

Objective There remains no consensus on a postoperative protocol following arthroscopic treatment of osteochondral lesions of the talus (OLTs) and most studies report a period of immobilization and nonweightbearing. Outcomes are believed to decrease with larger size. The purpose of our study was to evaluate patients who underwent arthroscopic treatment of large (≥150 mm2) OLTs with immediate unrestricted weightbearing and mobilization postoperatively. Design Patients who underwent arthroscopic bone marrow stimulation for osteochondral defects were identified. Exclusion criteria included lesions less than 150 mm2, additional procedures other than ligament reconstruction, incongruent ankle joint, arthritis, and tibial plafond lesions. Postoperatively, all patients were placed into a soft dressing and were allowed immediate weightbearing as tolerated. Patients were considered failures if their AOFAS (American Orthopaedic Foot and Ankle Society) score was less than 80 or if they underwent osteochondral transplant. Results Thirteen patients were available for follow-up. Two patients underwent osteochondral transplant and were considered failures. Of the remaining 11, the average follow-up time after surgery was 33 months (range, 7-59 months). Average age was 37 years (range, 15-56 years), and lesion size averaged 239 mm2 (range, 150-400 mm2). Average postoperative scores included foot function index 50 (range, 23-136), visual analog scale 3 (range, 0-8), and AOFAS hindfoot 82 (range, 40-100). The group’s overall success rate was 54% (7/13). Conclusion The results of our study are higher than those previously published studies on large lesions with a more restricted postoperative rehabilitation, suggesting that unrestricted weightbearing and range of motion does not diminish patient outcomes. Level of Evidence: IV, Case series.

Purpose: the aim of this study is to report the clinical and imaging results recorded by a series of patients in whom osteochondral lesions of the talus (OLTs) were repaired using the autologous collagen-induced chondrogenesis (ACIC) technique with a completely arthroscopic approach. Methods: nine patients (mean age 37.4±10 years) affected by OLTs (lesion size 2.1±0.9 cm2) were treated with the ACIC technique. The patients were evaluated clinically both preoperatively and at 12 months after surgery using the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS) and a visual analog scale (VAS). For morphological evaluation, the magnetic resonance observation of cartilage repair tissue (MOCART) score was used. Results: the AOFAS score improved from 51.4±11.6 preoperatively to 71.8±20.6 postoperatively, while the VAS value decreased from 6.9±1.8 to 3.2±1.9. The mean MOCART score was 51.7±16.6 at 12 months of follow-up; these scores did not directly correlate with the clinical results. Conclusions: use of the ACIC technique for arthroscopic repair of OLTs allowed satisfactory clinical results to be obtained in most of the patients as soon as one year after surgery, with no major complications or delayed revision surgery. ACIC is a valid and lowinvasive surgical technique for the treatment of chondral and osteochondral defects of the talus. Level of evidence: therapeutic case series, level IV.

Background: Primary rotator cuff repairs in complex cases (older patient age, larger tear sizes, chronic tears) and revision repairs are at high risk for failure of healing. Purpose: To examine clinical outcomes and healing rates in complex and revision rotator cuff repairs with dermal allograft augmentation. Study Design: Case series; Level of evidence, 4. Methods: A retrospective study was made of cases performed by 3 fellowship-trained surgeons via a uniform technique involving rotator cuff repairs with allograft augmentation. In all cases, a 1.5-mm, human, decellularized dermal graft was tied on top of the tendon at the medial row and compressed to the rotator cuff footprint using a double-row technique. Postoperative magnetic resonance imaging (MRI) was performed at a minimum of 6 months and American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and 12-Item Short Form Health Survey scores were collected at a minimum of 2 years postoperatively. Results: A total of 35 patients (23 revision repairs, 12 primary complex repairs) were included. The mean patient age was 57.9 years (range, 41.0-70.5 years). All shoulders had 2-tendon tears (supraspinatus and infraspinatus), and 8 included the upper 50% of the subscapularis. At a minimum of 2 years after surgery (mean, 3.2 years), mean ASES and SANE scores improved from 42.4 and 35.3 to 77.6 and 73.5, respectively ( P < .001). In the 23 patients (66%) with postoperative MRI evaluation, 11 (48%) had images showing the tendons were retorn. ASES (89.7 vs 66.4; P = .04) and SANE (84.1 vs 50.5; P = .02) scores were higher in healed patients than those with retears. The retear group had a higher degree of preoperative fatty atrophy of the infraspinatus ( P = .024). Conclusion: Double-row arthroscopic repair with dermal allograft augmentation of complex and revision rotator cuff tears led to improved functional outcomes. Approximately half of patients experienced a failure of healing, which was associated with poorer functional results.

Background: The purpose of this study was to evaluate the clinical and radiologic outcomes of patients younger than 20 years, treated with the arthroscopic-talus autologous matrix-induced chondrogenesis (AT-AMIC) technique and autologous bone graft for osteochondral lesion of the talus (OLT). Methods: Eleven patients under 20 years (range 13.3-20.0) underwent the AT-AMIC procedure and autologous bone graft for OLTs. Patients were evaluated preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively, using the American Orthopaedic Foot & Ankle Society Ankle and Hindfoot (AOFAS) score, the visual analog scale and the SF-12 respectively in its Mental and Physical Component Scores. Radiologic assessment included computed tomographic (CT) scan, magnetic resonance imaging (MRI) and intraoperative measurement of the lesion. A multivariate statistical analysis was performed. Results: Mean lesion size measured during surgery was 1.1 cm3 ± 0.5 cm3. We found a significant difference in clinical and radiologic parameters with analysis of variance for repeated measures ( P < .001). All clinical scores significantly improved ( P < .05) from T0 to T3. Lesion area significantly reduced from 119.1 ± 29.1 mm2 preoperatively to 77.9 ± 15.8 mm2 ( P < .05) at final follow-up as assessed by CT, and from 132.2 ± 31.3 mm2 to 85.3 ± 14.5 mm2 ( P < .05) as assessed by MRI. Moreover, we noted an important correlation between intraoperative size of the lesion and body mass index (BMI) ( P = .011). Conclusions: The technique can be considered safe and effective with early good results in young patients. Moreover, we demonstrated a significant correlation between BMI and lesion size and a significant impact of OLTs on quality of life. Level of Evidence: Level IV, retrospective case series.

Case Series Study

Background: Microfracture is the most common reparative surgery for osteochondral lesions of the talus (OLTs). While shown to be effective in short- to midterm outcomes, the fibrocartilage that microfracture produces is both biomechanically and biologically inferior to that of native hyaline cartilage and is susceptible to possible deterioration over time following repair. With orthobiologics being proposed to augment repair, there exists a clear gap in the study of long-term clinical outcomes of microfracture to determine if this added expense is necessary. Methods: A retrospective review of patients undergoing microfracture of an OLT with a single fellowship-trained orthopedic surgeon from 2007 to 2009 was performed. Patients meeting the inclusion criteria were contacted to complete the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscales and visual analog scale (VAS) for pain, as well as surveyed regarding their satisfaction with the outcome of the procedure and their likelihood to recommend the procedure to a friend with the same problem using 5-point Likert scales. Patient demographics were reviewed and included for statistical analysis. Results: Of 45 respondents, 3 patients required additional surgery on their ankle for the osteochondral defect, yielding a 10-year survival rate of 93.3%. Of surviving cases, 90.4% (38/42) reported being “extremely satisfied” or “satisfied” with the outcome of the procedure. The VAS score at follow-up averaged 14 out of 100 (range, 0-75), while the FAAM-ADL and FAAM-Sports scores averaged 90.29 out of 100 and 82 out of 100, respectively. Thirty-six patients (85.7%) stated that their ankle did not prevent them from participating in the sports of their choice. Conclusion: The current study represents a minimum 10-year follow-up of patients undergoing isolated arthroscopic microfracture for talar osteochondral defects, with a 93.3% survival rate and 85.7% return to sport. While biological adjuvants may play a role in improving the long-term outcomes of microfracture procedures, larger and longer-term follow-up studies are required for procedures using orthobiologics before their cost can be justified for routine use. Level of Evidence: Level IV, retrospective cohort case series study.

Background: The purpose of this article is to document the normal arthroscopic appearance of the posterior ankle capsular and ligamentous structures, and variations in their anatomical relationships. Methods: 102 ankle arthroscopy videotapes were evaluated retrospectively for the configuration of the posterior capsuloligamentous structures. Based on these observations, the variations in the appearance and position of the posterior tibiofibular ligament (PTFL) and transverse (tibiofibular) ligament (TTFL) were documented. In addition, differences in the appearance of the flexor hallucis longus (FHL) were also noted. Results: All patients had evidence of both a PTFL and TTFL, which formed a labrum or meniscus-like addition to the posterior distal tibia. No patients demonstrated disruption of the PTFL; 3 had tears of the TTFL. We noted 4 distinct patterns of the PTFL and the TTFL. Thirty-four patients (33%) had a gap of ≥2 mm between the 2 ligamentous structures. Thirty-three (32.4%) had a gap <2 mm between the PTFL and TTFL. Twenty-six (25.5%) had a confluence of the 2 ligaments without a gap. Nine (9%) demonstrated a sizable gap between the 2 ligaments, and the TTFL appeared as a “cord-like” structure. Conclusion: To our knowledge, this is the first article to describe the variations in the arthroscopic normal posterior capsuloligamentous structures and FHL of the ankle.

Radiographic Outcomes

Background: Autologous matrix-induced chondrogenesis (AMIC) has been shown to result in favorable clinical outcomes in patients with osteochondral lesions of the talus (OLTs). Though, the influence of ankle instability on cartilage repair of the ankle has yet to be determined. Purpose/Hypothesis: To compare the clinical and radiographic outcomes in patients with and without concomitant lateral ligament stabilization (LLS) undergoing AMIC for the treatment of OLT. It was hypothesized that the outcomes would be comparable between these patient groups. Study Design: Cohort study; Level of evidence, 3. Methods: Twenty-six patients (13 with and 13 without concomitant ankle instability) who underwent AMIC with a mean follow-up of 4.2 ± 1.5 years were enrolled in this study. Patients were matched 1:1 according to age, body mass index (BMI), lesion size, and follow-up. Postoperative magnetic resonance imaging and Tegner, American Orthopaedic Foot & Ankle Society (AOFAS), and Cumberland Ankle Instability Tool (CAIT) scores were obtained at a minimum follow-up of 2 years. A musculoskeletal radiologist scored all grafts according to the MOCART (magnetic resonance observation of cartilage repair tissue) 1 and MOCART 2.0 scores. Results: The patients’ mean age was 33.4 ± 12.7 years, with a mean BMI of 26.2 ± 3.7. Patients with concomitant LLS showed worse clinical outcome measured by the AOFAS (85.1 ± 14.4 vs 96.3 ± 5.8; P = .034) and Tegner (3.8 ± 1.1 vs 4.4 ± 2.3; P = .012) scores. Postoperative CAIT and AOFAS scores were significantly correlated in patients with concomitant LLS ( r = 0.766; P = .002). A CAIT score >24 (no functional ankle instability) resulted in AOFAS scores comparable with scores in patients with isolated AMIC (90.1 ± 11.6 vs 95.3 ± 6.6; P = .442). No difference was seen between groups regarding MOCART 1 and 2.0 scores ( P = .714 and P = .371, respectively). Conclusion: Concurrently performed AMIC and LLS in patients with OLT and ankle instability resulted in clinical outcomes comparable with isolated AMIC if postoperative ankle stability was achieved. However, residual ankle instability was associated with worse postoperative outcomes, highlighting the need for adequate stabilization of ankle instability in patients with OLT.
