Fresh Osteochondral Allograft

Introduction. Structural fresh osteochondral allograft transfer is an appropriate treatment option for large osteochondral lesions of the talus (OLTs), specifically lesions involving the shoulder of the talus. Sparse literature exists regarding functional outcome following this surgery in high-demand populations. Materials and Methods. Over a 2-year period, a single surgeon performed 8 structural allograft transfers for treatment of large OLTs in an active duty US military population. Lesion morphology and magnetic resonance imaging (MRI) stage were recorded. Preoperative and latest postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle and pain visual analog scores were compared. Results. Eight male service members with mean age 34.4 years underwent structural allograft transfer for OLTs with mean MRI stage of 4.9 and a mean lesion volume of 2247.1 mm3. Preoperative mean AOFAS hindfoot-ankle score was 49.6, and mean pain visual analog score was 6.9. At mean follow-up of 28.5 months, postoperative mean AOFAS score was 73, and mean pain visual analog score was 4.5, representing overall improvements of 47% and 35%, respectively. Three patients were considered treatment failures secondary to continued ankle disability (2) or graft resorption requiring ankle arthrodesis. Conclusions. Despite modest improvements in short-term functional outcome scores, large osteochondral lesions requiring structural allograft transfer remain difficult to treat, particularly in high-demand patient populations. Surgeons should counsel patients preoperatively on realistic expectations for return to function following structural allograft transfer procedures. Levels of Evidence: Level IV: Retrospective study

Fresh Osteochondral Allograft

Category: Ankle Introduction/Purpose: The term osteochondral lesion of the talus (OLT) refers to any pathology of the talar articular cartilage and corresponding subchondral bone. In general, OLTs can pose a formidable treatment challenge to the orthopaedic surgeon due to the poor intrinsic ability of cartilage to heal as well as the tenuous vascular supply to the talus. Although many treatment options exist, including microfracture, retrograde drilling, autologous chondrocyte implantation (ACI), and osteochondral autograft transfer system (OATS) these options may be inadequate to treat large cartilage lesions. Osteochondral allografts have demonstrated promise as the primary treatment for OLTs with substantial cartilage and bone involvement. To our knowledge, this is the first systematic review of outcomes after fresh osteochondral allograft transplantation for OLTs. Methods: PudMed, the Cochrane Central Register of Controlled Trials, EMBASE, and Medline were searched using PRISMA guidelines. Studies that evaluated outcomes in adult patients after fresh osteochondral allograft transplantation for chondral defects of the talus were included. Operative results, according to standardized scoring systems, such as the AOFAS Ankle/Hindfoot scale and the Visual Analog Scale were compared across various studies. The methodological quality of the included studies was assessed using the Coleman methodology score. Results: There were a total of 12 eligible studies reporting on 191 patients with OLTs with an average follow-up of 56.8 months (range 6-240). The mean age was 37.5 (range 17-74) years and the overall graft survival rate was 86.6%. The AOFAS Ankle/Hindfoot score was obtained pre- and postoperatively in 6 of the 12 studies and had significant improvements in each (P<0.05). Similarly, the VAS pain score was evaluated in 5 of the 12 studies and showed significant decreases (P<0.05) from pre- to postoperatively with an aggregate mean preoperative VAS score of 7.3 and an aggregate postoperative value of 2.6. The reported short-term complication rate was 0%. The overall failure rate was 13.4% and 21.6% percent of patients had subsequent procedures. Conclusion: The treatment of osteochondral lesions of the talus remains a challenge to orthopaedic surgeons. From this systematic review, one can conclude that osteochondral allograft transplantation for osteochondral lesions of the talus results in predictably favorable outcomes with an impressive graft survival rate and high satisfaction rates at intermediate follow-up.

Category: Basic Sciences/Biologics Introduction/Purpose: Large osteochondral lesion of the talus (OLT) can be difficult to treat. Although many treatment options exist, fresh osteochondral allograft transplantation has demonstrated promise as the primary treatment for OLTs with substantial cartilage and bone involvement as well as a secondary treatment option after failure of other cartilage repair techniques. Fresh osteochondral allografts are size-matched from organ donors and, in theory, have healthy articular cartilage and bone. However, the quality of allograft cartilage and bone has never been examined with respect to the OLT cartilage and bone being replaced. The purpose of this study was to perform a matched comparison of the cartilage and bone from patients OLTs to the fresh osteochondral allograft replacement. Methods: Discarded intact osteochondral specimens were collected from 8 patients undergoing surgery for an OLT. The specimens included the excised OLT and a portion of the fresh allograft replacement that the same patient received at the time of surgery. Histologic analysis was performed. The safranin-o histology was then scored using the International Cartilage Repair Society (ICRS) histopathology grading and staging system. In this system the grade determines cartilage and bone destruction on a scale of 0 to 6.5, the stage determines the percentage of involvement in the specimen on a scale of 0 to 4, and the total score is the grade multiplied by the stage. The surface roughness was also compared between the OLT and allograft cartilage using ImageJ software (NIH). Paired t-tests were performed on the ICRS grade, stage, and total score, and surface roughness comparing the OLTs and allografts. Significance was set at p<0.05. Results: Gross histological inspection of the samples demonstrated cartilage erosion and subchondral bone destruction in the OLTs. In constrast, the osteochondral allografts demonstrated intact cartilage surface and normal subchondral bone in the allografts (Figure 1). The ICRS grade, stage, and total score were significantly higher in the implanted allografts compared to the resected OLTs (Figure 2); indicating better cartilage and bone morphology for the allografts compared to the OLTs. In fact, the mean grade and stage for the allograft samples were both less than a score of 1 which corresponds to healthy cartilage and bone with less than 10% surface fibrillations. Moreover, the surface roughness of the allograft cartilage was significantly smoother than the OLT cartilage. Conclusion: This is the first study to demonstrate that the use of fresh allograft transplantation for the treatment of OLTs replaces the damaged cartilage and bone with normal or near normal cartilage and bone. The replacement of damaged cartilage and subchondral bone with normal or near normal cartilage and bone may be the reason for improved pain relief and functional outcomes after fresh allograft transplantation for OLTs.

Background: Structural or bulk osteochondral allograft transplantation for shoulder talar osteochondral lesions as a salvage procedure has demonstrated efficacy in several retrospective reviews. The purpose of this study was to evaluate prospectively patients who received fresh structural allograft transplantation to the talus. Methods: Prospective evaluation of a consecutive series of patients who underwent fresh structural allograft transplantation for an osteochondral lesion of the talus (OLT) was performed. Preoperative magnetic resonance imaging (MRI) and/or computed tomography (CT) and plain radiographs were obtained on all patients. The following patient-reported outcomes questionnaires were administered preoperatively and yearly after surgery: 100-mm visual analog scale (VAS) pain scale, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale, Short Form 36 (SF-36), and the Short Musculoskeletal Functional Assessment (SMFA). Preoperative and postoperative radiographs were assessed for allograft incorporation and subsequent arthritis. Fourteen patients with an average age of 40 years (range, 18-69) and a mean follow-up of 55 months (range, 24-97) underwent structural fresh osteochondral allograft transplantation to the talar shoulder. Results: The average size of the OLT was 2269 mm3 (range, 813-8366) based on CT imaging and 5797 mm3 (range, 1136-12 489) based on MRI imaging. There was significant ( P < .05) improvement in the VAS pain, AOFAS scale, SF-36, and SMFA scores. Five (36%) of the patients required additional surgery for pain and stiffness. Two patients had cartilage delamination and were considered treatment failures. Therefore, the success rate was 86% (12/14). Conclusion: Significant improvement in pain and function was achieved with structural allograft transplantation for large OLTs at midterm follow-up. This was a safe and effective treatment option in this small series for large OLTs. Level of Evidence: Level IV, prospective case series.

Objective The purpose of this study was to evaluate functional outcomes and allograft survivorship among patients with knee fracture who underwent fresh osteochondral allograft (OCA) transplantation as a salvage treatment option. Design Retrospective analysis of prospectively collected data. Setting Department of Orthopaedic Surgery at one hospital. Patients Fresh OCAs were implanted for osteochondral lesions after knee fracture in 24 males and 15 females with an average age of 34 years. Twenty-nine lesions (74%) were tibial plateau fractures, 6 (15%) were femoral condyle fractures, and 4 (10%) were patella fractures. Main Outcome Measurements Clinical evaluation included modified Merle d’Aubigné-Postel (18-point), International Knee Documentation Committee, and Knee Society function scores, and patient satisfaction. Failure of OCA was defined as revision OCA or conversion to total knee arthroplasty (TKA). Results Nineteen of 39 knees (49%) had further surgery. Ten knees (26%) were considered OCA failures (3 OCA revisions, 6 TKA, and 1 patellectomy). Survivorship of the OCA was 82.6% at 5 years and 69.6% at 10 years. Among the 29 knees (74%) that had the OCA still in situ, median follow-up was 6.6 years. Pain and function improved from preoperative to latest follow-up; 83% of patients reported satisfaction with OCA results. Conclusion OCA transplantation is a useful salvage treatment option for osteochondral lesions caused by knee fracture. Although the reoperation rate was high, successful outcome was associated with significant clinical improvement.

Spectrum Of Patients

AbstractKnee patients who have sustained chondral and osteochondral lesions suffer from debilitating pain, which can ultimately lead to posttraumatic osteoarthritis and whole-joint disease. Older, nonactive patients are traditionally steered toward total knee arthroplasty (TKA), but younger, active patients are not good candidates for TKA based on implant longevity, complications, morbidity, and risk for revision, such that treatment strategies at restoring missing hyaline cartilage and bone are highly desired for this patient population. Over the past four decades, fresh osteochondral allograft (OCA) transplantation has been developed as a treatment method for large (> 2.5 cm2) focal full-thickness articular cartilage lesions. This article documents our own institutional OCA journey since 2016 through enhanced graft preservation techniques (the Missouri Osteochondral Preservation System, or MOPS), technical improvements in surgical techniques, use of bone marrow aspirate concentrate, bioabsorbable pins and nails, and prescribed and monitored patient-specific rehabilitation protocols. Further follow-up with documentation of long-term outcomes will provide insight for continued optimization for future applications for OCA transplantation, potentially including a broader spectrum of patients appropriate for this treatment. Ongoing translational research is necessary to blaze the trail in further optimizing this treatment option for patients.

Background Scaphoid nonunion can occur in up to 55% of displaced scaphoid fractures. Long-term functional outcomes of this injury are lacking. In addition, no study has published rate of return to active military service after this injury. Our goal was to educate providers and patients on expected functional outcomes and return to duty after treatment of scaphoid nonunion. Methods We conducted a retrospective review of patients who underwent scaphoid nonunion repair at our institution from 2008 to 2017. The primary outcome measures were union rates, return to duty rates, and functional outcome scores obtained by telephone call. A total of 144 patients were included and 40 responded to our call for long-term follow-up. Results A total of 72% of patients achieved union after surgery, 18% required revision surgery, and 74% of patients were able to return to full duty after surgery. However, this number progressively decreased at 1, 2, and 5 years after surgery. At an average of 5.9 years after surgery, the mean Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) score was 23.9. The mean qDASH for patients who achieved union (21.9) was significantly lower than those with persistent nonunion (29.2) ( P = .0115). Conclusion Scaphoid nonunion is a difficult problem in the military. We found a high rate of persistent nonunion often requiring revision to partial or full wrist arthrodesis. In addition, our long-term functional outcome scores demonstrate significant disability after this injury, even when union is achieved. This information can help us better counsel our patients and set expectations after treatment of this injury.
