The Ischemic toe following forefoot surgery: A review of current practices and a proposed approach for management.

Toe hypoperfusion is a commonly encountered concern following forefoot surgery, yet there is limited clinical guidance available to surgeons to aid in management of this scenario. This work aims to review the etiology, pathophysiology and current strategies to address a perioperative ischemic toe. The authors review various interventions to approach this problem based on available evidence and clinical experience. Interventions to restore perfusion can be loosely based on the ischemic causality they intend to address. Described maneuvers to restore perfusion have, in turn, been designed to either chemically (through topical/local medication) or mechanically (bending/removing K-wires, adjusting repair tension) aid in mitigation of the offending cause. Depending upon the type of surgery performed, which may or may not include instrumentation, a surgeon can implement a series of steps to maximize restoration of toe perfusion. LEVEL OF EVIDENCE: V.

Assessment of variables that influence agreement between reviewers for Foot & Ankle International.

INTRODUCTION: A common criticism of the peer-review process is the often disparate nature of reviewer recommendations when a decision is rendered which belies the supposed uniformity of the process. The purpose of this investigation was to examine level of agreement between reviewers for Foot & Ankle International (FAI) and analyze variables which may have influenced agreement in order to better understand the peer-review process. METHODS: Approval to conduct this investigation was obtained from the Executive Board and Editor in Chief of FAI. All manuscripts submitted to FAI during the calendar year 2016 which underwent formal peer-review were included in the analysis. For each reviewed manuscript, demographic data was collected regarding specific reviewer and manuscript characteristics in a de-identified manner. RESULTS: 442 manuscripts underwent formal blinded peer-review by two independent reviewers during the study period. Only 199 manuscripts (45%) had a decision rendered in which both reviewers agreed on the same initial recommendation. There were no differences in demographic characteristics between the group of reviewers who agreed as compared to those who disagreed on the initial round of peer review. A similar number of indexed peer-reviewed publications between reviewers correlated with increased levels of agreement. CONCLUSIONS: During the study period, there was 45% initial agreement between reviewers for FAI when assessing the same manuscript. Aside from research productivity, no other reviewer-specific variables examined in this investigation were found to correlate with agreement. Specific recommendations and changes may be considered to increase the efficiency and effectiveness of the peer-review process.

Editorial Commentary: The Great Endoscopically Assisted Bunion Surgery That Will Never Become Popular-I Will Not Try This at Home.

Bunion surgery almost invariably involves osteotomies and open incisions. Recently, some surgeons have been performing minimally invasive osteotomies with less morbidity, more rapid healing, and good results. These surgeries are heavily technique dependent, and other surgeons cannot always reproduce these results. Endoscopically assisted bunion surgery yielded excellent results at 10 years in this study but will likely never be used commonly because of the extremely demanding surgical technique and requisite learning curve.

Challenges and Controversies of Foot and Ankle Trauma.

Traumatic injury to the foot and ankle can result in long-term disability, which may have substantial negative implications on a patient's functional outcomes and quality of life. The diagnosis and appropriate management of these challenging injuries are not always agreed on or straightforward. In particular, the appropriate diagnosis and management of distal tibiofibular syndesmotic injuries as well as the surgical approach and role of primary subtalar arthrodesis for intra-articular calcaneal fractures are controversial.

Polymethylmethacrylate (PMMA) Augmentation Enhances the Mechanical Characteristics of Midfoot Beam Constructs in Charcot Neuroarthropathy Cadaver Model.

BACKGROUND: Even with the best conservative care, patients with Charcot neuroarthropathy (CN) of the foot and ankle often ulcerate, increasing their risk of infection, amputation, and death. Surgical fixation has been associated with risk of recurrent ulceration, potentially due to poor bone quality prone to recurrent deformity and ulceration. We propose midfoot beam reconstruction with PMMA augmentation as a novel means of improving fixation. METHODS: A protocol was developed to create characteristic CN midfoot fragmentation both visually and fluoroscopically in each of 12 matched-pair cadaveric feet. Afterward, the pairs were divided into 2 groups: (1) midfoot beam fusion surgery alone, and (2) midfoot beam fusion surgery augmented with PMMA. A solid 7.0-mm beam was placed into the medial column and a solid 5.5-mm beam was placed across the lateral column. In the PMMA group, 8 to 10 mL of PMMA was inserted into the medial column. The hindfoot of each specimen was potted and the metatarsal heads were cyclically loaded for 1800 cycles, followed by load to failure while load and displacement were continually recorded. RESULTS: One specimen in the beam alone group failed before reaching the 1800th cycle and was not included in the failure analysis. The midfoot beam only group demonstrated greater mean displacement during cycle testing compared with the PMMA group, P < .05. The maximum force (N), stiffness (N/mm), and toughness (Nmm) were all significantly greater in the group augmented with PMMA, P < .05. CONCLUSION: In a CN cadaveric model, PMMA augmentation significantly decreased gapping during cyclic loading and nearly doubled the load to failure compared with midfoot beams alone. CLINICAL RELEVANCE: The results of this biomechanical study demonstrate that augmentation of midfoot beams with PMMA increases the strength and stiffness of the fusion construct. This increased mechanical toughness may help reduce the risk of nonunion and infection in patients with neuropathic midfoot collapse.

Lateral column length in adult flatfoot deformity.

INTRODUCTION: In adult acquired flatfoot deformity, it is unclear whether the lateral column length shortens with progression of the deformity, whether it is short to begin with, or whether it is short at all. To our knowledge, no previous study has examined the lateral column length of patients with adult acquired flatfoot deformity compared to a control population. The purpose of our study was to compare the lateral column length in patients with and without adult acquired flatfoot deformity to see if there was a significant difference. METHODS: The study was a retrospective radiographic review of 2 foot and ankle fellowship-trained orthopaedic surgeons' patients with adult flatfoot deformity. Our study population consisted of 75 patients, 85 feet (28 male, 57 female) with adult flatfoot deformity with a mean age of 64 (range, 23-93). Our control population consisted of 57 patients and 70 feet (23 male, 47 female) without flatfoot deformity with a mean age of 61 (range, 40-86 years). Weightbearing anteroposterior (AP) and lateral foot radiographs were analyzed for each patient, and the following measurements were made: medial and lateral column lengths, talonavicular uncoverage angle, talus-first metatarsal angle, calcaneal pitch angle, and medial and lateral column heights. An unpaired t test was used to analyze the measurements between the groups. Ten patients' radiographs were remeasured, and correlation coefficients were obtained to assess the reliability of the measuring techniques. RESULTS: For the flatfoot group, the mean medial and lateral column lengths on the AP radiograph were 108.6 mm and 95.8 mm, respectively; the mean talo-navicular uncoverage angle was 26.2 degrees; and the mean talus-first metatarsal angle was 20.0 degrees. In the control group, the mean medial and lateral column lengths on the AP radiograph were 108.8 mm and 96.5 mm, respectively; the mean talo-navicular uncoverage angle was 8.2 degrees; and the mean talus-first metatarsal angle was 7.7 degrees. On the lateral radiograph in the flatfoot group, the mean medial and lateral column lengths were 167.2 mm and 166.6 mm, respectively; the mean medial and lateral column heights were 16.0 mm and 14.7 mm, respectively; the mean calcaneal pitch angle was 15.6 degrees; and the talus-first metatarsal angle was 10.3 degrees and for the control group, the mean medial and lateral column lengths were 165.3 mm and 163.5 mm, respectively; the mean medial and lateral column heights were 22.8 mm and 13.1 mm, respectively; the mean calcaneal pitch angle was 22.4 degrees; and the talus-first metatarsal angle was -3.6 degrees. None of the differences in measurements for medial and lateral column lengths between the flatfoot and control groups achieved statistical significance. However, statistically significant differences between the 2 groups were observed in the measurements for medial and lateral column heights, talo-navicular uncoverage angle, calcaneal pitch angle, and talus-first metatarsal angle. CONCLUSION: There is no difference in lateral column lengths between patients with and without adult flatfoot deformity. The perceived shortened lateral column is likely due to forefoot abduction and hindfoot valgus deformities that are associated with adult flatfoot deformity. LEVEL OF EVIDENCE: Level III, comparative series.

Effect of various hallux valgus reconstruction on sesamoid location: a radiographic study.

BACKGROUND: The correction of sesamoid subluxation is an important component of hallux valgus reconstruction with some surgeons feeling that the sesamoids can be pulled back under the first metatarsal head when imbricating the medial capsule during surgery. The purpose of this study was to radiographically assess the effect of an osteotomy on sesamoid location relative to the second metatarsal. METHODS: This is a retrospective radiographic study review of 165 patients with hallux valgus treated with reconstructive osteotomies. Patients were included if they underwent a scarf or basilar osteotomy for hallux valgus but were excluded if they had inflammatory arthropathy or lesser metatarsal osteotomy. A modified McBride soft tissue procedure was performed in conjunction with the basilar and scarf osteotomies. Each patient's preoperative and postoperative radiographs were evaluated for hallux valgus angle, intermetatarsal 1-2 angle, tibial sesamoid classification, and lateral sesamoid location relative to the second metatarsal. RESULT: The greatest correction of both hallux valgus and intermetatrsal 1-2 angle was achieved in basilar osteotomies (20.6 degrees and 9.7 degrees, respectively), then scarf osteotomies (14.4 degrees and 8.7 degrees, respectively). Basilar and scarf osteotomies both corrected medial sesamoid subluxation relative to the first metatarsal head an average of 2-3 classification stages. All osteotomies had minimal lateral sesamoid location change relative to the second metatarsal. CONCLUSION: The majority of sesamoid correction correlated with the intermetatarsal 1-2 correction. The concept that medial capsular plication pulls the sesamoids beneath the first metatarsal (ie, changes the location of the sesamoids relative to the second metatarsal) was not supported by our results.

Ipsilateral intact fibula as a predictor of tibial plafond fracture pattern and severity.

BACKGROUND: The objective of this study was to determine whether there is a difference in fracture pattern and severity of comminution between tibial plafond fractures with and without associated fibular fractures using computed tomography (CT). We hypothesized that the presence of an intact fibula was predictive of increased tibial plafond fracture severity. METHODS: This was a case control, radiographic review performed at a single level I university trauma center. Between November 2007 and July 2011, 104 patients with 107 operatively treated tibial pilon fractures and preoperative CT scans were identified: 70 patients with 71 tibial plafond fractures had associated fibular fractures, and 34 patients with 36 tibial plafond fractures had intact fibulas. Four criteria were compared between the 2 groups: AO/OTA classification of distal tibia fractures, Topliss coronal and sagittal fracture pattern classification, plafond region of greatest comminution, and degree of proximal extension of fracture line. RESULTS: The intact fibula group had greater percentages of AO/OTA classification B2 type (5.5 vs 0, P = .046) and B3 type (52.8 vs 28.2, P = .013). Conversely, the percentage of AO/OTA classification C3 type was greater in the fractured fibula group (53.5 vs 30.6, P = .025). Evaluation using the Topliss sagittal and coronal classifications revealed no difference between the 2 groups (P = .226). Central and lateral regions of the plafond were the most common areas of comminution in fractured fibula pilons (32% and 31%, respectively). The lateral region of the plafond was the most common area of comminution in intact fibula pilon fractures (42%). There was no statistically significant difference (P = .71) in degree of proximal extension of fracture line between the 2 groups. CONCLUSIONS: Tibial plafond fractures with intact fibulas were more commonly associated with AO/OTA classification B-type patterns, whereas those with fractured fibulas were more commonly associated with C-type patterns. An intact fibula may be predictive of less comminution of the plafond. The lateral and central regions of the plafond were the most common areas of comminution in tibial plafond fractures, regardless of fibular status. LEVEL OF EVIDENCE: Level III, case control study.

Republication of "Preliminary Experience Using Bioactive Glass Wedges for Cotton Osteotomy".

Background: Medial cuneiform dorsal opening wedge (Cotton) osteotomy is often used for treating forefoot varus in patients undergoing surgery for stage II posterior tibialis tendon dysfunction. The goal of this study was to examine the radiographic outcomes of Cotton osteotomy with bioactive glass wedge to assess for both maintenance of correction and clinical results and complications. We hypothesized that bioactive glass wedges would maintain correction of the osteotomy with low complication rates. Methods: Between December 2015 and June 2016, the charts of 17 patients (10 female and 7 male) who underwent Cotton osteotomy using bioactive glass wedges were retrospectively reviewed. Patient age averaged 56.8 years (range, 16-84). The average follow-up was 6.5 months. Radiographs were reviewed to assess for initial correction and maintenance of correction of medial column sag as well as for union. Charts were reviewed for complications. Results: The medial column sag correction averaged 15.6% on the final postoperative lateral radiograph. Meary angle averaged 19 degrees (3.14-42.8 degrees) preoperatively and 5.5 degrees (0.4-20.7 degrees) at final follow-up. All patients achieved clinical and radiographic union. One patient developed neuropathic midfoot pain and was managed with sympathetic blocks. One patient had a delayed union that healed at 6 months without surgical intervention. No patients required the use of custom orthotics or subsequent surgical procedures. Conclusion: Cotton osteotomy with bioactive glass wedges produced consistent correction of the medial column with low risk. Level of Evidence: Level IV, case series.

Accuracy of Pain Tolerance Self-assessment Versus Objective Pressure Sensitivity.

INTRODUCTION: Effective treatment of postoperative pain after elective surgery remains elusive, and the experience of pain can be variable for patients. The patient's intrinsic pain tolerance may contribute to this variability. We sought to identify whether there was a correlation between subjective report of intrinsic pain tolerance and objective measurement of pressure dolorimetry (PD). We also sought to identify whether a correlation existed between PD and Patient Reported Outcome Measurement Information System (PROMIS) scores of pain intensity, physical function, and mood. PD is a validated, objective method to assess pain tolerance. Markers of general mental and physical health are correlated with pain sensitization and may also be linked to pain tolerance. METHODS: PROMIS scores, dolorimetry measurements, and survey data were collected on 40 consecutive orthopaedic foot and ankle surgery patients at the initial clinic visit. Patients were included if they had normal sensation on the plantar foot and no prior surgery or plantar heel source of pain. RESULTS: Objective dolorimetry data reflecting 5/10 pain for the patients were 24 N/cm 2 (±8.9). Patients estimated their pain threshold as 7.3/10 (±2.1). No correlation was found between objective and subjective pain threshold identified. A moderate negative correlation of R = -0.44 was observed regarding PROMIS-M with dolorimetry data ( P < -0.05). PROMIS-M score >60 had a significant decrease in pain threshold to 15.9 ± 8.5 N/cm 2 compared with 25.7 ± 8.9 N/cm 2 for those who were less depressed with a PROMIS<60 ( P < 0.05). CONCLUSION: Subjective pain tolerance is not correlated with the patient's own objective pain threshold or markers of mental health and should not be used to assist clinical decision making. PROMIS-M is inversely correlated with objective pain. Higher PROMIS-M scores are associated with a lower objective pain threshold.

Incidence of deep vein thrombosis and pulmonary embolism after Achilles tendon rupture.

BACKGROUND: The use of venous thromboembolism prophylaxis after an Achilles rupture is controversial. The rates of reported deep vein thrombosis (DVT) range from 6.3% to 34%. There is no agreement regarding prophylactic therapy after an Achilles tendon rupture. QUESTIONS/PURPOSES: We determined the overall risk of DVT and pulmonary embolism (PE) after an Achilles tendon rupture and identified potential risk factors including surgery. PATIENTS AND METHODS: We retrospectively reviewed a large healthcare management organization database and identified 1172 patients who had Achilles tendon ruptures. None of the patients routinely received anticoagulation. Patients were stratified into surgical versus nonsurgical group, age older than 40 years, history of congestive heart failure, previous history of DVT or PE, and BMI greater than 30. A patient was considered to have symptomatic DVT or PE related to the Achilles tendon rupture if diagnosed within 3 months from the injury or surgery. We used a multivariable analysis to identify risk factors. RESULTS: The overall rates for DVT and PE after Achilles tendon ruptures were 0.43% and 0.34%, respectively. Age older than 40 years, congestive heart failure, history of DVT or PE, obesity, and whether a patient had surgery did not predict occurrence of DVT or PE. CONCLUSION: We found the overall incidence of symptomatic DVT and PE to be low after an Achilles tendon rupture and believe routine use of anticoagulation might be unwarranted.

Insertional Achilles tendinitis and Haglund's deformity.

BACKGROUND: Haglund's deformity is an enlargement of the posterosuperior prominence of the calcaneus, which is frequently associated with insertional Achilles tendinitis. To our knowledge, no study has been done successfully correlating the characteristics of a Haglund's deformity with insertional Achilles tendinitis. The purpose of our study was to analyze the characteristics of a Haglund's deformity in patients with and without insertional Achilles tendinitis to see if there was a correlation. METHODS: The study was a retrospective radiographic review of a single surgeon's patients with insertional Achilles tendinitis from 2005 to 2008. Our study population consisted of 44 patients, 48 heels (22 male, 22 female) with insertional Achilles tendinitis, with a mean age of 52 (range, 23 to 79) years. Our control population consisted of 50 patients (25 males, 25 females) and 50 heels without insertional Achilles tendinitis with a mean age of 55.6 (range, 18 to 89) years. We introduced two new measurements of the Haglund's deformity in this study: the Haglund's deformity height and peak angle. A standing lateral foot or ankle radiograph was analyzed for each patient and the following measurements were made: Haglund deformity height and peak angle; Bohler's angle; Fowler-Philip angle; and parallel pitch sign. We also looked for the presence of calcification in the study group and the length and width of the calcification. Unpaired t-test was used to analyze the measurements between the groups. Ten patients' radiographs were re-measured and correlation coefficients were obtained to assess the reliability of the measuring techniques. RESULTS: For the insertional Achilles tendinitis group, the mean Haglund's deformity height was 9.6 (range, 5.3 to 15.3) mm and the mean Haglund's deformity peak angle was 105 (range, 87 to 123) degrees. Calcification was present in 35 of 48 or (73%) of patients with a mean length of 13.3 (range, 3.2 to 41.9) mm and mean width of 4.5 (range, 1.0 to 10.4) mm. In the control group, the mean Haglund's deformity height was 9.0 (range, 5.2 to 12.1) mm and the peak angle was 105 (range, 91 to 124) degrees. Bohler's angle and Fowler-Philip angle were also similar between the groups and the positive parallel pitch sign was actually more prevalent in the control group (60% versus 41.7%). None of the differences in measurements between the groups achieved statistical significance. CONCLUSION: A Haglund's deformity was not indicative of insertional Achilles tendinitis and was present in asymptomatic patients. Also, a majority of the insertional Achilles tendinitis patients had calcification at the tendon insertion. We believe it is possible removing the Haglund's deformity may not be necessary in the operative treatment of insertional Achilles tendinitis.

Radiographic assessment of medial cuneiform opening wedge osteotomy for flatfoot correction.

BACKGROUND: Opening wedge osteotomy of the medial cuneiform has become an established intervention for correction of forefoot varus in relation to a flatfoot deformity. The purpose of this study was to use a newly described radiographic measurement to determine the effectiveness and durability of the medial column correction with a plantarflexion opening wedge osteotomy of the medial cuneiform without internal fixation using an allograft. METHODS: Twenty-three feet underwent medial cuneiform opening wedge osteotomies for correction of forefoot varus associated with flatfoot deformity. The angle between the proximal and distal articular surfaces was measured on lateral radiographs preoperatively, postoperatively prior to weightbearing and at final followup visit. RESULTS: The average angle between the proximal and distal articular surfaces of the medial cuneiform on lateral foot radiographs was 1.0 degree preoperatively (±0.8 degrees). The average angle post-osteotomy, pre-weightbearing, was 8.4 degrees (±3.6 degrees) and at final followup was 7.5 degrees (±2.9 degrees). All patients achieved bony union. CONCLUSION: We describe a new radiographic measurement to focus on the correction achieved by a plantarflexion osteotomy of the medial cuneiform. It was found to be stable without internal fixation and reliably proceeded to union without significant loss of correction.

Results of calcaneocuboid distraction arthrodesis.

BACKGROUND: One powerful method of reconstructing an adult acquired flatfoot deformity is a calcaneocuboid distraction arthrodesis. We performed a retrospective review of a small series of patients who underwent a calcaneocuboid distraction arthrodesis with a femoral head allograft. MATERIALS AND METHODS: Sixteen feet (14 patients) were identified with an average follow up of 23 months (8-39 months) and an average age of 43 years (16-60 years). A calcaneocuboid distraction arthrodesis was performed with a femoral head allograft, secured with a 3 hole 1/3 tubular plate with 7 of the grafts being supplemented with platelet rich plasma (PRP). Patients were kept non-weight bearing for 6 weeks with an additional 6 weeks in a walking cast or boot. Plain radiographs and if necessary a CT or MRI were used to evaluate for union. RESULTS: Seven of the 16 feet developed a nonunion. Five of 9 patients without PRP developed a nonunion vs 2 of 7 patients where PRP was used. CONCLUSION: Due to the unacceptably high complication rate with this procedure, the authors have abandoned this procedure. If an allograft is to be used for a calcaneocuboid arthrodesis, the authors strongly recommend using rigid locking fixation with a longer period of protected immobilization.

Evaluation and Management of Adult Footdrop.

Footdrop is a common musculoskeletal condition defined by weakness in ankle joint dorsiflexion. Although the etiology varies, footdrop is characterized by specific clinical and gait abnormalities used by the patient to overcome the loss of active ankle dorsiflexion. The condition is often associated with deformity because soft-tissue structures may become contracted if not addressed. Patients may require the use of special braces or need surgical treatment to address the notable level of physical dysfunction. Surgical treatment involving deformity correction to recreate a plantigrade foot along with tendon transfers has been used with notable success to restore a near-normal gait. However, limitations and postoperative dorsiflexion weakness have prompted investigation in nerve transfer as a possible alternative surgical treatment.

First metatarsal length change after basilar closing wedge osteotomy for hallux valgus.

BACKGROUND: Hallux valgus deformities with large intermetatarsal angles require a more proximal metatarsal procedure to adequately correct the deformity. Due to the relative ease of a closing wedge osteotomy, this technique was adopted but with concern over first metatarsal shortening. In this study, we primarily evaluated angular correction and first metatarsal shortening. MATERIALS AND METHODS: We evaluated 70 feet in 57 patients (average age, 54 years) with 52 female and five male. The average followup was 14 (range, 6 to 45) months. The charts were reviewed for the presence of metatarsalgia. Digital radiographic measurements were made for pre- and postoperative hallux valgus and intermetatarsal angles, dorsiflexion angle of the first metatarsal, and absolute and relative shortening of the first metatarsal. RESULTS: The average hallux valgus angle improved from 31 to 11 degrees (p < 0.0001) and intermetatarsal angle from 13.2 to 4.4 angles (p < 0.0001). The absolute shortening of the first metatarsal was 2.2 mm and relative shortening was 0.6 mm. There was 1.3 degrees of dorsiflexion on average. CONCLUSION: Excellent correction of the deformity with minimal dorsiflexion or new complaints of metatarsalgia was found with this technique. The new method of assessing the relative shortening found to be less than the absolute shortening, which we feel more accurately reflects the functional length of the first metatarsal.

Special report: highlights of the twenty-fifth annual summer meeting of the American Orthopaedic Foot and Ankle Society, Vancouver, Canada, July 16-18, 2009.

The Twenty-fifth Annual Summer Meeting of the American Orthopaedic Foot and Ankle Society (AOFAS) was held 16-18 July 2009 at the Westin Bayshore Hotel in Vancouver, British Columbia, Canada. There were 521 registered attendees, including 339 (65%) individuals from 42 of the United States and 182 (35%) attendees from 32 countries outside the United States.

Dexamethasone Addition to Popliteal Nerve Blocks: Effects on Duration of Analgesia and Incidence of Postoperative Nerve Complication.

Background. The purpose of this prospective, double-blinded randomized control pilot study was to evaluate the effect of adjunctive dexamethasone on analgesia duration and the incidence of postoperative neuropathic complication. Peripheral nerve blocks are an effective adjunct to decrease postoperative pain in foot and ankle surgery, and any possible modalities to augment their efficacy is of clinical utility. Methods. Patients were randomly assigned to a control group (n = 25) receiving nerve blocks of bupivacaine and epinephrine or an experimental group (n = 24) with an adjunctive 8 mg dexamethasone. The patients, surgeons, and anesthesiologists were all blinded to allocation. Patients had a minimum 1 year postoperative follow-up. Results. Forty-nine patients completed the protocol. There was no statistically significant difference in analgesia duration (P = .38) or postoperative neuropathic complication incidence (P = .67) between the 2 groups. Conclusions. The addition of dexamethasone to popliteal nerve blocks does not appear to affect analgesia duration or incidence of postoperative neuropathic complications. However, our study was underpowered, and we recommend a larger scale prospective study for validation.Levels of Evidence: Level II: Prospective, randomized control pilot study.

Career Outlook and Performance of Professional Athletes After Achilles Tendon Rupture: A Systematic Review.

BACKGROUND: The purpose of this systematic review is to examine the literature on Achilles tendon (AT) injuries in professional athletes to determine their rate of return to play (RTP), performance, and career outcome after AT rupture. METHODS: A literature search of MEDLINE, Google Scholar, CINAHL, and Cochrane Library databases was performed. Included studies reported outcomes related to RTP (time and rate), durability and player participation, and player performance following AT rupture in professional athletes of the National Football League (NFL), National Basketball Association (NBA), Major League Baseball (MLB), and professional soccer leagues. RESULTS: Fifteen studies met inclusion criteria for analysis. Athletes were able to return to professional sport participation 76% of the time, with mean time to RTP of 11 months following AT injury. Athletes experienced a decline in player efficiency ratings, power ratings, and sport- and position-specific statistics in the NFL, NBA, and professional soccer leagues compared to noninjured controls. RTP rate was significantly lower following AT rupture in comparison to athletes sustaining other common orthopedic injuries such as anterior cruciate ligament injuries, meniscal tears, and ankle fractures in both NFL and NBA athletes. CONCLUSION: AT rupture prohibits nearly 25% of professional athletes from returning to their respective sport. Of those able to return to compete at a professional level, the mean time to RTP is 11 months-nearly double the estimated 6-month recovery for RTP in the general population. Furthermore, player performance and durability were curtailed following AT rupture. This review of the literature should be used to set evidence-based goals and establish realistic expectations for RTP for elite athletes following AT injuries.
