RESUMO

Background and Objective: Graft selection for anterior cruciate ligament reconstruction (ACLR) affects rehabilitation throughout the course of postoperative care. Methods: A search of PubMed and EBSCO was performed and abstracts independently reviewed by two authors. This search was also supplemented with additional evidence relevant to each phase of ACLR rehabilitation. Key Content and Findings: Direct implications of graft type on clinical decisions vary throughout treatment phases, transitioning from potential differences in acute postoperative pain management immediately after surgery to facilitating sufficient and appropriate lower extremity loading in subsequent weeks. Regardless of graft type, surgical limb weakness persists throughout the course of rehabilitation; however, harvest site selection for autografts contributes to disproportionate weakness of the harvested muscle group and the potential for surgical-induced tendinopathy. In later phases of rehabilitation, as athletes are transitioning into return to sport (RTS), treatment decisions and protocols are less affected by graft type but expectations for meeting clinical milestones and the time required to do so does differ between graft types. Conclusions: Targeted strengthening interventions to address muscle weakness following graft harvest in autografts should be continued throughout the rehabilitation process. Lingering deficits in quadriceps strength symmetry may also influence time to meet progression and RTS criteria following graft harvest from the extensor mechanism.

RESUMO

BACKGROUND:: Fractures of the proximal fifth metatarsal are one of the most common foot injuries in athletes. Repetitive stresses endured by the fifth metatarsal can lead to stress fracture, delayed union, and refracture, making optimal treatment challenging. A radiographic analysis of fifth metatarsal morphology and foot type in National Football League (NFL) players was performed to investigate morphologic risk factors for these injuries. METHODS:: This was a case-control study that looked at NFL players treated between 1992 and 2012, as well as participants at the NFL Combine. Ninety-six feet (51 athletes) were included. Fractures were present in 15 feet. Two reviewers assessed fifth metatarsal morphology and foot type on anteroposterior, lateral, and oblique radiographs. Differences in foot type and metatarsal morphology between athletes with and without fractures were determined. RESULTS:: On anteroposterior radiographs, significant differences in apex medullary canal width, 4-5 intermetatarsal angle, fifth metatarsal angle, and talar head uncovering were observed between fractured and non-fractured feet ( P = .001, .003, .004, .008, respectively). On lateral radiographs, significant differences in the fifth metatarsal length, distance to apex, apex height, fifth metatarsal angle, and talocalcaneal angle were observed between fractured and nonfractured feet ( P = .04, .01, .02, .01, .01, respectively). On oblique radiographs, a significant difference was observed in apex height between fractured and nonfractured feet ( P = .002). CONCLUSION:: Individuals with long, narrow, and straight fifth metatarsals with an adducted forefoot were most at risk for fifth metatarsal fractures. With this insight, attempts at fracture prevention can be implemented via footwear modifications, orthoses, and off-loading braces that account for those aforementioned morphologic attributes that place athletes at risk. LEVEL OF EVIDENCE:: Level III, retrospective comparative study.

RESUMO

BACKGROUND: Tibialis anterior tendon ruptures are rare and can cause significant dysfunction. Often, conservative measures are prescribed because of the morbidity of a tendon transfer as an operative solution. We present a novel reconstruction technique using hamstring autograft, which may obviate the need for local tendon transfer and long-term bracing. METHODS: Patients who underwent tibialis anterior reconstruction with hamstring autograft between 2011 and 2015 were screened for inclusion. Eight were included. Functional outcomes were assessed pre-and-postoperatively using the Foot and Ankle Outcome Score (FAOS), Visual Analog Pain Scale (VAS), and Short-Form-12 (SF-12) general health questionnaire. Isokinetic testing using a dynamometer (Biodex System 4 Pro) was performed at 60 and 120 degrees/s, respectively, for inversion/eversion and plantarflexion/dorsiflexion on both ankles at a minimum of 6 months postoperatively to determine peak torque, average power, and total work. Range of motion (ROM) testing was also performed, using a goniometer, at a minimum of 6 months postoperatively. Average follow-up was 17.3 (6.0-40.0) months for strength testing and ROM testing, and 18.5 (12.0-26.0) months for functional outcome scores. RESULTS: Average postoperative functional scores improved for all tests. ROM was similar between the uninvolved and involved ankles for inversion/eversion and plantarflexion/dorsiflexion. Patients showed deficits in dorsiflexion strength in all measures tested and improvements in inversion strength. All patients were able to ambulate without a brace. CONCLUSION: Use of a hamstring autograft for tibialis anterior reconstruction resulted in good clinical outcomes. This procedure successfully restored ankle ROM postoperatively and tendon strength in inversion and dorsiflexion, with most patients showing little deficit when comparing their involved and uninvolved sides. LEVEL OF EVIDENCE: Level IV, Case series.

RESUMO

BACKGROUND: The purpose of this study was to compare the functional and radiographic outcomes of patients who received juvenile allogenic chondrocyte implantation with autologous bone marrow aspirate (JACI-BMAC) for treatment of talar osteochondral lesions with those of patients who underwent microfracture (MF). METHODS: A total of 30 patients who underwent MF and 20 who received DeNovo NT for JACI-BMAC treatment between 2006 and 2014 were included. Additionally, 17 MF patients received supplemental BMAC treatment. Retrospective chart review was performed and functional outcomes were assessed pre- and postoperatively using the Foot and Ankle Outcome Score and Visual Analog pain scale. Postoperative magnetic resonance images were reviewed and evaluated using a modified Magnetic Resonance Observation of Cartilage Tissue (MOCART) score. Average follow-up for functional outcomes was 30.9 months (range, 12-79 months). Radiographically, average follow-up was 28.1 months (range, 12-97 months). RESULTS: Both the MF and JACI-BMAC showed significant pre- to postoperative improvements in all Foot and Ankle Outcome Score subscales. Visual Analog Scale scores also showed improvement in both groups, but only reached a level of statistical significance ( P < .05) in the MF group. There were no significant differences in patient reported outcomes between groups. Average osteochondral lesion diameter was significantly larger in JACI-BMAC patients compared to MF patients, but size difference had no significant impact on outcomes. Both groups produced reparative tissue that exhibited a fibrocartilage composition. The JACI-BMAC group had more patients with hypertrophy exhibited on magnetic resonance imaging (MRI) than the MF group ( P = .009). CONCLUSION: JACI-BMAC and MF resulted in improved functional outcomes. However, while the majority of patients improved, functional outcomes and quality of repair tissue were still not normal. Based on our results, lesions repaired with DeNovo NT allograft still appeared fibrocartilaginous on MRI and did not result in significant functional gains as compared to MF. LEVEL OF EVIDENCE: Level III, comparative series.

RESUMO

Juvenile allogenic chondrocyte implantation (JACI; DeNovo NT Natural Tissue Graft®; Zimmer, Warsaw, IN) with autologous bone marrow aspirate concentrate (BMAC) is a relatively new all-arthroscopic procedure for treating critical-size osteochondral lesions (OCLs) of the talus. Few studies have investigated the clinical and radiographic outcomes of this procedure. We collected the clinical and radiographic outcomes of patients who had undergone JACI-BMAC for talar OCLs to assess treatment efficacy and cartilage repair tissue quality using magnetic resonance imaging (MRI). Forty-six patients with critical-size OCLs (≥6 mm widest diameter) received JACI-BMAC from 2012 to 2014. We performed a retrospective medical record review and assessed the functional outcomes pre- and postoperatively using the Foot and Ankle Outcome Score (FAOS) and Short-Form 12-item general health questionnaire. MRI was performed preoperatively and at 12 and 24 months postoperatively. Cartilage morphology was evaluated on postoperative MRI scans using the magnetic resonance observation of cartilage tissue (MOCART) score. The pre- to postoperative changes and relationships between outcomes and lesion size, bone grafting, lesion location, instability, hypertrophy, and MOCART scores were analyzed. Overall, the mean questionnaire scores improved significantly, with almost every FAOS subscale showing significant improvement postoperatively. Concurrent instability resulted in more changes that were statistically significant. The use of bone grafting and the presence of hypertrophy did not result in statistically significant changes in the outcomes. Factors associated with outcomes were lesion size and hypertrophy. Increasing lesion size was associated with decreased FAOS quality of life subscale and hypertrophy correlating with changes in the pain subscale. Of the 46 patients, 22 had undergone postoperative MRI scans that were scored. The average MOCART score was 46.8. Most patients demonstrated a persistent bone marrow edema pattern and hypertrophy of the reparative cartilage. Juvenile articular cartilage implantation of the DeNovo NT allograft and BMAC resulted in improved functional outcome scores; however, the reparative tissue still exhibited fibrocartilage composition radiographically. Further studies are needed to investigate the long-term outcomes and determine the superiority of the arthroscopic DeNovo procedure compared with microfracture and other cartilage resurfacing procedures.

RESUMO

BACKGROUND: Hamstring tendon autografts may be used for foot and ankle surgeries, although reports on their effectiveness and morbidity in the foot and ankle literature are limited. We studied a cohort of patients who underwent hamstring harvest for foot and ankle applications, hypothesizing that morbidity to the knee would be limited. METHODS: We studied a cohort of patients who underwent hamstring autograft for foot or ankle applications by a fellowship-trained sports and foot and ankle surgeon since 2011. Thirty-seven patients underwent isokinetic strength testing using a dynamometer an average of 38 months postoperatively. The average patient age was 45 ± 16 (range, 18-78) years, and 54% were women. Peak flexion and extension torque as well as flexion and extension torque at 30, 70, and 90 degrees of flexion were collected at 2 different testing speeds, 180 and 300 degrees/s. t tests were used for all comparisons. RESULTS: At follow-up, 32 patients (86%) reported no pain at the harvest site; the remaining 5 patients reported mild to moderate symptoms. No patients were dissatisfied, and all would recommend the surgery to someone else. Flexion strength at higher degrees of flexion was significantly lower compared with extension strength as well as compared with flexion strength at lower degrees of flexion, when testing was performed at lower speed ( P < 0.05). CONCLUSIONS: When used for foot and ankle surgery, hamstring autografts resulted in high patient satisfaction with minimal donor site morbidity. While knee flexion strength was decreased at higher degrees of flexion, this finding did not appear to be clinically significant. LEVEL OF EVIDENCE: Level IV, case series.

RESUMO

We report a unique case of an epithelioid hemangioma of the third middle phalanx in which the lesion replaced the phalanx, became symptomatic, and then required resection, bone grafting, and joint arthroplasty. To the best of our knowledge, this is the first report of an epithelioid hemangioma in the toe that was treated using this approach.

RESUMO

BACKGROUND: Chronic Achilles injury is often treated with flexor hallucis longus (FHL) tendon transfer to the calcaneus using 1 or 2 incisions. A single incision avoids the risks of extended dissections yet yields smaller grafts, which may limit fixation options. We investigated the required length of FHL autograft and biomechanical profiles for suture anchor and biotenodesis screw fixation. METHODS: Single-incision FHL transfer with suture anchor or biotenodesis screw fixation to the calcaneus was performed on 20 fresh cadaveric specimens. Specimens were cyclically loaded until maximal load to failure. Length of FHL tendon harvest, ultimate load, stiffness, and mode of failure were recorded. RESULTS: Tendon harvest length needed for suture anchor fixation was 16.8 ± 2.1 mm vs 29.6 ± 2.4 mm for biotenodesis screw ( P = .002). Ultimate load to failure was not significantly different between groups. A significant inverse correlation existed between failure load and donor age when all specimens were pooled (ρ = -0.49, P < .05). Screws in younger specimens (fewer than 70) resulted in significantly greater failure loads ( P < .03). No difference in stiffness was found between groups. Modes of failure for screw fixation were either tunnel pullout (n = 6) or tendon rupture (n = 4). Anchor failure occurred mostly by suture breakage (n = 8). CONCLUSION: Adequate FHL tendon length could be harvested through a single posterior incision for fixation to the calcaneus with either fixation option, but suture anchor required significantly less graft length. Stiffness, fixation strength, and load to failure were comparable between groups. An inverse correlation existed between failure load and donor age. Younger specimens with screw fixation demonstrated significantly greater failure loads. CLINICAL RELEVANCE: Adequate harvest length for FHL transfer could be achieved with a single posterior incision. There was no difference in strength of fixation between suture anchor and biotenodesis screw.

RESUMO

BACKGROUND: Suture-button constructs are an alternative to screw fixation for syndesmotic injuries, and proponents advocate that suture-button constructs may allow physiological motion of the syndesmosis. Recent biomechanical data suggest that fibular instability with syndesmotic injuries is greatest in the sagittal plane, but the design of a suture-button construct, being a rope and 2 retention washers, is most effective along the axis of the rope (in the coronal plane). Some studies report that suture-button constructs are able to constrain fibular motion in the coronal plane, but the ability of a tightrope to constrain sagittal fibular motion is unknown. The purpose of this study was to assess fibular motion in response to an external rotation stress test in a syndesmotic injury model after fixation with a screw or suture-button constructs. METHODS: Eleven fresh-frozen cadaver whole legs with intact tibia-fibula articulations were secured to a custom fixture. Fibular motion (coronal, sagittal, and rotational planes) in response to a 6.5-Nm external rotation moment applied to the foot was recorded with fluoroscopy and a high-resolution motion capture system. Measures were taken for the following syndesmotic conditions: intact, complete lateral injury, complete lateral and deltoid injury, repair with a tetracortical 4.0-mm screw, and repair with a suture button construct (Tightrope; Arthrex, Naples, FL) aimed from the lateral fibula to the anterior medial malleolus. RESULTS: The suture-button construct allowed significantly more sagittal plane motion than the syndesmotic screw. Measurements acquired with mortise imaging did not detect differences between the intact, lateral injury, and 2 repair conditions. External rotation of the fibula was significantly increased in both injury conditions and was not restored to intact levels with the screw or the suture-button construct. CONCLUSION: A single suture-button placed from the lateral fibula to the anterior medial malleolus was unable to replicate the motion observed in the intact specimen when subjected to an external rotation stress test and allowed significantly more posterior motion of the fibula than when fixed with a screw in simulated highly unstable injuries. CLINICAL RELEVANCE: Fixation of a syndesmotic injury with a single suture-button construct did not restore physiological fibular motion, which may have implications for postoperative care and clinical outcomes.

RESUMO

BACKGROUND: First metatarsophalangeal (MTP) joint arthrodesis is a common procedure for treatment of arthritis of the first MTP joint. The primary aim of this study was to evaluate the functional outcomes of a series of patients of multiple surgeons undergoing first MTP joint arthrodesis, emphasizing the functional gains with respect to daily activity that can be expected after this procedure. METHODS: A retrospective review of 53 patients who underwent successful isolated first MTP joint arthrodesis with either a plate and screw or independent screw construct was performed at our institution over a 6-year period. Successful fusion was defined as no lucency at the first MTP joint and bridging of 2 or more cortices on the anteroposterior, lateral, and oblique radiographic views at final follow-up. Demographic information and radiographs were evaluated for all patients. Preoperative and postoperative Foot and Ankle Outcome Score (FAOS) and Short Form Health Status Survey (SF) 36/12 functional outcome scores, as well as responses from an activity- and footwear-specific questionnaire, were evaluated and compared between the 2 fixation methods. Fifty-three patients (56 feet) had radiographs showing successful fusions after being treated for advanced degenerative arthritis of the first MTP joint with arthrodesis. Average time to union was 5.4 months. RESULTS: There was a significant reduction in difficulty in performing daily activities, with all subscales of the FAOS and the SF-12v2 significantly improving postoperatively (P < .05). The majority of patients stated that their foot looked and felt better and were satisfied with the procedure. Five patients experienced painful hardware, which required removal. CONCLUSION: First MTP joint arthrodesis was successful in improving patient-reported outcomes, particularly the ability to perform daily activities. Most patients had little to no functional limitation and were satisfied with their outcome. The greatest functional improvements were seen in patients' ability to walk distances and perform low-impact sport activity. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

RESUMO

BACKGROUND: Proximal fractures of the fifth metatarsal (zone II and III) are common in the elite athlete and can be difficult to treat because of a tendency toward delayed union, nonunion, or refracture. The purpose of this case series was to report our experience in treating 10 NBA players, determine the healing rate, return to play, refracture rate, and role of foot type in these athletes. METHODS: The records of 10 professional basketball players were retrospectively reviewed. Seven athletes underwent standard percutaneous internal fixation with bone marrow aspirate concentrate (BMAC) whereas the other 3 had open bone grafting primarily in addition to fixation and BMAC. Radiographic features evaluated included fourth-fifth intermetatarsal, fifth metatarsal lateral deviation, calcaneal pitch, and metatarsus adductus angles. RESULTS: Radiographic healing was observed at an overall average of 7.5 weeks and return to play was 9.8 weeks. Three athletes experienced refractures. There were no significant differences in clinical features or radiographic measurements except that the refracture group had the highest metatatarsus adductus angles. Most athletes were pes planus and 9 of 10 had a bony prominence under the fifth metatarsal styloid. CONCLUSION: This is the largest published series of operatively treated professional basketball players who exemplify a specific patient population at high risk for fifth metatarsal fracture. These players were large and possessed a unique foot type that seemed to be associated with increased risk of fifth metatarsal fracture and refracture. This foot type had forefoot metatarsus adductus and a fifth metatarsal that was curved with a prominent base. We continue to use standard internal fixation with bone marrow aspirate but advocate additional prophylactic open bone grafting in patients with high fourth-to-fifth intermetatarsal, fifth metatarsal lateral deviation, and metatarsus adductus angles as well as prominent fifth metatarsal styloids in order to improve fracture healing and potentially decrease the risk of refracture. LEVEL OF EVIDENCE: Level IV, case series.

RESUMO

BACKGROUND: Percutaneous internal fixation is currently the method of choice treating proximal zone II fifth metatarsal fractures. Complications have been reported due to poor screw placement and inadequate screw sizing. The purpose of this study was to define the morphology of the fifth metatarsal to help guide surgeons in selecting the appropriate screw size preoperatively. METHODS: Multiplanar analysis of fifth metatarsal morphology was completed using computed tomographic (CT) scans from 241 patients. Specific parameters were analyzed and defined in anteroposterior (AP), lateral, and oblique views including metatarsal length, distance from the base to apex of curvature, apex medullary canal width, apex height, and fifth metatarsal angle. RESULTS: The average metatarsal length in the AP view was 71.4 ± 6.1 mm and in the lateral view 70.4 ± 6.0 mm, with 95% of patients having lengths between 59.3 and 83.5 mm and 58.4 and 82.4 mm, respectively. The average canal width at the apex of curvature was 4.1 ± 0.9 mm in the AP view and 5.3 ± 1.1 mm in the lateral view, with 95% of patients having widths between 2.2 and 5.9 mm and 3.2 and 7.5 mm, respectively. Average distance from apex to base was 42.6 ± 5.8 mm in the AP and 40.4 ± 6.4 mm in the lateral views. Every measurement taken in all 3 views had a significant correlation with height. CONCLUSIONS: When determining screw length, we believe lateral radiographs should be used since the distance from the base of the metatarsal to the apex was smaller in the lateral view. On average, the screw should be 40 mm or less to reduce risk of distraction. For screw diameter, the AP view should be used because canal shape is elliptical, and width was found to be significantly smaller in the AP view. Most canals can accommodate a 4.0- or 4.5-mm-diameter screw, and one should use the largest diameter screw possible. Larger individuals were likely to have more bowing in their metatarsal shaft, which may lead to a higher tendency to distract. LEVEL OF EVIDENCE: Level III, comparative series.

RESUMO

BACKGROUND: Current literature reports excellent rates of union following various lesser metatarsal osteotomy techniques. However, it is our experience that segmental midshaft shortening osteotomies heal very slowly and have a greater potential for nonunion than has previously been reported. The purpose of this study was to assess union rates and report the time required for segmental midshaft shortening osteotomies to achieve radiographic union. METHODS: We reviewed the charts and postoperative radiographs of 58 patients (representing 91 osteotomies) who underwent segmental midshaft shortening osteotomies with internal fixation between January 2009 and December 2013. Radiographs were reviewed to determine when union was achieved. Union was defined as the bridging of 2 or more cortices in the anteroposterior, lateral, and oblique radiographic views. Osteotomies were classified as delayed union if they were not healed at 3 months postoperatively and nonunions if they were not healed at 6 months postoperatively. RESULTS: Overall, 27 of 91 osteotomies met our radiographic classification of union and were healed by 3 months (29.7%). Sixty-nine of the 91 osteotomies healed by 6 months (75.8%) and were considered delayed unions. Twenty-two osteotomies were not healed yet and therefore were considered nonunions (24.2%). Of the 22 nonunions, 7 healed in an additional 2 months (8 months) for an overall healing percentage of 83.5%, (76 of 91). By 10 months, 6 more nonunions were healed (overall healing percentage of 90.1%, 82 of 91). Three additional nonunions went on to heal by 12.9 months, yielding a final union rate of 93.4% (85 of 91), while 6 were still considered nonunions (6.6%). CONCLUSION: We report that a significant percentage of segmental midshaft metatarsal shortening osteotomies experienced delayed unions and nonunions. These findings contrast those previously reported in the literature that metatarsal osteotomies have very low nonunion rates. These results support our hypothesis that these osteotomies require a prolonged amount of time to achieve bony healing and that they have a higher tendency to develop delayed and nonunions than previously reported. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

BACKGROUND: The calcaneal osteotomy is a common procedure to correct hindfoot malalignment. Reported union rates are high, utilizing fixation methods including staples, plates, and most commonly cannulated screws. We began our practice using 6.5 mm and 7.3 mm cannulated screws, but complaints of postoperative posterior heel pain led to hardware removal in many patients. A switch to smaller 4.5 mm cannulated screws resulted in fewer symptoms, thus we hypothesized that using a smaller screw would decrease screw removal while maintaining an equally high union rate. METHODS: The records of patients who underwent a calcaneal osteotomy by 2 surgeons between January 1996 and April 2012 were retrospectively reviewed. The rates of hardware removal and union were compared between osteotomies held with two 7.3 mm, 6.5 mm, and 4.5 mm cannulated screws. RESULTS: There were 272 feet that met the inclusion criteria. The hardware removal rate for 130 osteotomies held with two 7.3 mm screws was 29.2% and the removal rate for 115 osteotomies held with 4.5 mm screws was 13.0%, which was significantly different (P < .05). The removal rate for 27 osteotomies with 6.5 mm screws was 33.3%. The union rate for all groups was 100%. CONCLUSION: Fixation of calcaneal osteotomies with two 4.5 mm screws is advantageous over larger screws with respect to future hardware removal. There was no loss of position from the smaller screws and we feel that the 4.5mm cannulated screw provides sufficient compression and achieves a high rate of union equal to that of the larger screws.

RESUMO

Shoulder pain is the third most frequent musculoskeletal complaint presented to physicians. Often considered a benign entity by patients and even their physicians, shoulder disorders can have a devastating effect on a patient's ability to function, as well as serve as an indicator of poor general health. For these reasons, it is important for the physician to be able to identify the etiology of a patient's shoulder problem(s). However, making a correct diagnosis is often difficult because there can be many causes for a patient's shoulder pain, weakness, or loss of function. Moreover, the shoulder girdle is an intricate group of structures that work together to allow for the largest range of motion in the body. This complexity makes it difficult to diagnose a patient's condition(s) based on history alone. A thorough and well-performed physical examination is the key to making a correct diagnosis and helping to distinguish different etiologies of shoulder dysfunction. In this article, we review relevant shoulder anatomy and biomechanics, and general shoulder examinations with special tests for various shoulder pathologies. We provide an effective and methodical approach to the physical examination of the shoulder.
