  • Double row equivalent for rotator cuff repair: A biomechanical analysis of a new technique JOURNAL OF ORTHOPAEDICS Robinson, S., Krigbaum, H., Kramer, J., Purviance, C., Parrish, R., Donahue, J. 2018; 15 (2): 426–31

    Abstract

    There are numerous configurations of double row fixation for rotator cuff tears however, there remains to be a consensus on the best method. In this study, we evaluated three different double-row configurations, including a new method. Our primary question is whether the new anchor and technique compares in biomechanical strength to standard double row techniques.Eighteen prepared fresh frozen bovine infraspinatus tendons were randomized to one of three groups including the New Double Row Equivalent, Arthrex Speedbridge and a transosseous equivalent using standard Stabilynx anchors. Biomechanical testing was performed on humeri sawbones and ultimate load, strain, yield strength, contact area, contact pressure, and a survival plots were evaluated.The new double row equivalent method demonstrated increased survival as well as ultimate strength at 415N compared to the remainder testing groups as well as equivalent contact area and pressure to standard double row techniques.This new anchor system and technique demonstrated higher survival rates and loads to failure than standard double row techniques. This data provides us with a new method of rotator cuff fixation which should be further evaluated in the clinical setting.Basic science biomechanical study.

  • The in vivo relationship between anterior neutral tibial position and loss of knee extension after transtibial ACL reconstruction KNEE Scanlan, S. F., Donahue, J. P., Andriacchi, T. P. 2014; 21 (1): 74-79

    Abstract

    Restoration of anterior tibial stability while avoiding knee extension deficit are a common goal of anterior cruciate ligament (ACL) reconstruction. However, achieving this goal can be challenging. The purpose of this study was to determine whether side-to-side differences in anterior tibial neutral position and laxity are correlated with knee extension deficit in subjects 2years after ACL reconstruction.In the reconstructed and contralateral knees of 29 subjects with transtibial reconstruction, anterior tibiofemoral neutral position was measured with MRI and three-dimensional modeling techniques; terminal knee extension at heel strike of walking and during a seated knee extension were measured via gait analysis; and anterior laxity was measured using the KT-1000.Knees that approached normal anterior stability and anterior tibial position had increased extension deficit relative to the contralateral knee. On average the reconstructed knee had significantly less (2.1±4.4°) extension during active extension and during heel strike of walking (3.0±4.3º), with increased anterior neutral tibial position (2.5±1.7mm) and anterior laxity (1.8±1.0mm). There was a significant correlation between side-to-side difference in anterior neutral tibial position with both measures of knee extension (walking, r=-0.711, p<0.001); active knee extension, r=-0.544, p=0.002).The results indicate a relationship between the loss of active knee extension and a change in anterior neutral tibial position following non-anatomic transtibial ACL reconstruction. Given the increasing evidence of a link between altered kinematics and premature osteoarthritis, these findings provide important information to improve our understanding of in vivo knee function after ACL reconstruction.

  • Three-dimensional knee moments of ACL reconstructed and control subjects during gait, stair ascent, and stair descent JOURNAL OF BIOMECHANICS Zabala, M. E., Favre, J., Scanlan, S. F., Donahue, J., Andriacchi, T. P. 2013; 46 (3): 515-520

    Abstract

    Changes in knee mechanics following anterior cruciate ligament reconstruction (ACLR) have been implicated as a contributor to the development of premature osteoarthritis (OA). However, changes in ambulatory loading in this population have not been well documented. While the magnitude of the external knee moment vector is a major factor in loading at the knee, there is not a comprehensive understanding of the changes in the individual components of the vector following ACL reconstruction. The purpose of this study was to test for differences in the three components of the external knee moment during walking and stair locomotion between ACLR, contralateral and healthy control knees. Forty-five ACLR and 45 healthy control subjects were tested during walking, stair ascent and descent. ACLR knees had a lower first peak adduction moment than contralateral knees during all three activities. Similarly, additional cases of significant differences between ACLR and contralateral knees consisted of lower peak moments for the ACLR than the contralateral knees. These differences were due to both ACLR and contralateral knees as the ACLR knees indicated lower and the contralateral knees greater peak moments compared to healthy control knees. The results suggest a compensatory change involving greater loading in the contralateral knee, perhaps due to lower loading of the ACLR knee. Further, lower knee moments of the ACLR knee suggest that increased joint loading may not be the initiating factor in the development of OA following ACL reconstruction; but rather previous described kinematic or biological changes might initiate the pathway to knee OA.

  • Variations in the three-dimensional location and orientation of the ACL in healthy subjects relative to patients after transtibial ACL reconstruction JOURNAL OF ORTHOPAEDIC RESEARCH Scanlan, S. F., Lai, J., Donahue, J. P., Andriacchi, T. P. 2012; 30 (6): 910-918

    Abstract

    Recent reports have indicated that anatomical placement of the anterior cruciate ligament (ACL) graft is an important factor for restoration of joint function following ACL reconstruction. The objective of this study was to address a need for a better understanding of anatomical variations in ACL position and orientation within the joint. Specifically, variations in the ACL anatomy were assessed by testing for side-to-side ACL footprint location symmetry in a healthy population relative to the operative and contralateral knee in a patient population after traditional transtibial single-bundle ACL reconstruction. MRI and three-dimensional modeling techniques were used to determine the in vivo tibiofemoral ACL footprint centers and the resulting ACL orientations in both knees of 30 healthy subjects and 30 subjects after transtibial ACL reconstruction. While there were substantial inter-subject variations in ACL anatomy, the side-to-side RMS differences in the ACL footprint center were 1.20 and 1.34 mm for the femur and tibia, respectively, for the healthy subjects and no clinically meaningful intra-subject differences were measured. However, there were large intra-subject side-to-side differences after transtibial ACL reconstruction, with ACL grafts placed 5.63 and 7.64 mm from the center of the contralateral femoral and tibial ACL footprint centers, respectively. Grafts were placed more medial, anterior, and superior on the femur and more posterior on the tibia; producing grafts that were more vertical in the sagittal and coronal planes. Given the large variation among subjects, these findings advocate the use of the contralateral ACL morphology for retrospectively evaluating patient-specific anatomic graft placement.

  • Coracoclavicular stabilization using a suture anchor technique. American journal of orthopedics (Belle Mead, N.J.) Friedman, D. J., Barron, O. A., Catalano, L., Donahue, J. P., Zambetti, G. 2008; 37 (6): 294–300

    Abstract

    Multiple fixation options exist for coracoclavicular stabilization, but many are technically demanding and require hardware removal. In the study reported here, we reviewed a specific fixation technique that includes suture anchors moored in the base of the coracoid process. We retrospectively reviewed 24 consecutive cases of patients who underwent coracoclavicular stabilization with a suture anchor for a type III or type V acromioclavicular (AC) joint separation or a group II, type II or type V distal clavicle fracture. Eighteen of the 22 patients had full strength and painless range of motion (ROM) in the affected extremity by 3 months and at final follow-up (minimum, 24 months; mean, 39 months). Two patients were lost to follow-up. Four patients had early complications likely secondary to documented noncompliance. Two of these 4 patients underwent reoperation with a similar procedure and remained asymptomatic at a minimum follow-up of 15 months. One patient underwent osteophyte and knot excision 7 months after surgery and remained asymptomatic at 30 months. Our results suggest that coracoclavicular stabilization using a suture anchor technique is a safe and reliable method of treating acromioclavicular joint separations and certain distal clavicle fractures in the compliant patient.

  • Vesicant characteristics of oxapliplatin following antecubital extravasation CLINICAL ONCOLOGY Kennedy, J. G., Donahue, J. P., Hoang, B., Boland, P. J. 2003; 15 (5): 237–39

    Abstract

    Oxaliplatin is a novel class of platinum chermotherapeutic agent used in refractory adenocarcinoma. It has previously been regarded as a non-vesicant, and as such was considered safe to administer through peripheral veins. This report documents severe muscle and subcutaneous reaction with a single dose of oxaliplatin at the site of extravasation in a patient aged 58 years. Conventional therapeutic modalities were employed to reduce the effect of the soft tissue infiltrate. Despite that, significant muscle necrosis and fibrosis occurred. Surgery was deferred secondary to patient choice, and eventual extensive physical therapy restored function to the elbow joint. This case shows that oxaliplatin may not be an appropriate cytotoxic agent to be administered through a peripheral line and consideration must be made for central access when this drug is used. In addition, when extravasation does occur, the current report indicates that non-surgical management can be successful.

  • Postoperative cell mediated immune response is better preserved after laparoscopic vs open colorectal resection in humans SURGICAL ENDOSCOPY AND OTHER INTERVENTIONAL TECHNIQUES Whelan, R. L., Franklin, M., Holubar, S. D., Donahue, J., Fowler, R., Munger, C., Doorman, J., Balli, J. E., Glass, J., Gonzalez, J. J., Bessler, M., Xie, H., Treat, M. 2003; 17 (6): 972–78

    Abstract

    Animal studies have documented significantly better preserved postoperative cell-mediated immune function, as measured by serial delayed-type hypersensitivity (DTH) challenges, after laparoscopic-assisted than after open bowel resection. Similarly, in humans, the DTH responses after open cholecystectomy have been shown to be significantly smaller than preoperative responses; whereas after laparoscopic cholecystectomy, no significant change in DTH response has been noted. The purpose of this study was to assess cell-mediated immune function via serial DTH skin testing in patients undergoing laparoscopic or open colectomy.A total of 35 subjects underwent either laparoscopic (n = 18) or open colectomy (n = 17) in this prospective but not randomized study. Only patients who were judged to be immunoresponsive by virtue of having responded successfully to a preoperative DTH challenge were eligible for entry in the study. DTH challenges were carried out at three time points in all patients: preoperatively, immediately following surgery, and on the third postoperative day (POD 3). Responses were measured 48 h after each challenge and the area of induration calculated. There were no significant differences between the laparoscopic (LC) and open (OC) colorectal resection groups in regard to demographics, indications for surgery, or type of resection carried out. The percentage of patients transfused was similar in both groups (17%, LC; 12% OC; p = NS). In the LC group, all cases were completed without conversion using minimally invasive methods. There were no perioperative deaths, and the rate of postoperative complications was similar in both groups. The preoperative and postoperative DTH results were analyzed and compared within each surgical group using several methods.In regards to the OC group results, the median sum-total DTH responses for the day of surgery challenges (0.44 +/- 69 cm2) and the POD 3 challenges (0.72 +/- 3.37 cm2) were significantly smaller than the preoperative results (3.61 +/- 3.83 cm2, p <0.0005 vs op day and p <0.0003 vs POD 3 results). When the LC group results were similarly analyzed, no significant difference in DTH response was noted between the pre- and the postoperative challenge results. Additionally, when the median percent change from baseline was calculated and considered for the OC group's DTH results, both postoperative challenge time points demonstrated significantly decreased responses when compared to their preoperative results (vs day of surgery, p <0.007; vs POD 3, p <0.006). Similar analysis of the LC group's results yielded nonsignificant differences between the pre- and postoperative responses. Lastly, when the LC and the OC groups median percent change from baseline results were directly compared for each of the postoperative challenges, a significant difference was noted for the POD 0 challenge (LC, -21%; OC 88%; p <0.004) but not for the POD 3 challenge.The postoperative DTH responses of the open surgery patients were significantly smaller than their preoperative responses. This was not the case for the laparoscopic group (a combination of fully laparoscopic and laparoscopic-assisted resections). When the open and laparoscopic groups results are directly compared, regarding the results of the day of surgery DTH challenges, the LC groups median percent change from baseline was significantly less than that observed in the OC group. These results imply that open colorectal resection is associated with a significant suppression of cell-mediated immune response postoperatively, whereas in this study laparoscopic colorectal resection was not. Further human studies are needed to verify these findings and to determine the clinical significance, if any, of this temporary difference in immune function following colon resection.

  • Metastatic breast carcinoma to bone disguised by osteopoikilosis SKELETAL RADIOLOGY Kennedy, J. G., Donahue, Aydin, H., Hoang, B. H., Huvos, A., Morris, C. 2003; 32 (4): 240–43

    Abstract

    A case of metastatic lobular carcinoma of the breast in conjunction with osteopoikilosis is described. Widespread diffuse sclerotic bone lesions were identified on radiographs in a patient with breast carcinoma. In addition computed tomography demonstrated discrete spherical areas of increased density throughout the skeleton manifest typically by osteopoikilosis. No systemic symptoms were evident, blood parameters were normal and the lesions did not demonstrate any increased uptake of technetium on bone scan. An iliac crest bone biopsy, however, revealed metastatic disease in addition to osteopoikilosis. Conventional radiological investigations may not delineate metastasis on a background of bone dysplasia.

  • Combined physeal/apophyseal fracture of the proximal tibia with anterior angulation from an indirect force: report of 2 cases. American journal of orthopedics (Belle Mead, N.J.) Donahue, J. P., Brennan, J. F., Barron, O. A. 2003; 32 (12): 604–7

    Abstract

    Physeal fracture of the proximal tibia is a rare injury, comprising less than 2% of all physeal injuries. The literature distinguishes between tibial tubercle avulsions (apophyseal injuries) classified by Ogden, Tross, and Murphy as type I, II, and III and Salter-Harris II fractures. An extensive review of the literature located only 5 cases in which patients sustained a combined fracture of the proximal tibial physis and tibial tubercle. We report 2 such cases, which are not amenable to classification by current systems, and agree with Ryu and Debenham's suggestion to add a fourth type, avulsion hinge fracture of the proximal tibial epiphysis, to the Watson-Jones/Ogden classification.

  • Wound tensile strength and contraction rate are not affected by laparotomy or pneumoperitoneum SURGICAL ENDOSCOPY-ULTRASOUND AND INTERVENTIONAL TECHNIQUES Wickens, J. C., Whelan, R. L., Allendorf, J. D., Donahue, J., Buxton, E., McKee, A., Panageas, K., Gleason, N., Lee, S., Bessler, M. 1998; 12 (9): 1166–70

    Abstract

    Many cellular elements responsible for wound healing are affected by laparotomy. The aim of this study was to evaluate the effects of laparotomy and CO2 pneumoperitoneum on wound healing.Male Sprague Dawley rats were randomly assigned to one of three experimental groups. Anesthesia control rats underwent no procedure. Pneumoperitoneum group rats were insufflated with CO2 gas. Laparotomy group rats underwent a 7-cm midline laparotomy incision. The interventions were 30 min long. For the incisional study (n = 30), a 4-cm dorsal full-thickness skin incision was made on each rat and then closed with staples. On postoperative days 7 and 14, an equal number of rats were sacrificed from each group, and wound tensile strength measurements were performed. For the excisional study (n = 45), each group of 15 rats underwent a 2-cm diameter circular dorsal full-thickness skin excision. Blinded measurements of wound area were performed every other day until wounds closed.Wound tensile strength values were not significantly different among experimental groups at either time point. The study had a power of 80% to find a 30% difference at POD 7 and a power of 80% to find a 23% difference at POD 14 to a confidence level of p < 0.05. Wound contraction data from the excisional model were analyzed with the Generalized Estimation Equations statistical approach. When we modeled the treatment group as a covariate, no statistical difference was found between groups, demonstrating equal slopes across time.From the results of these studies, we conclude that wound healing in this model is not significantly diminished following laparotomy or peritoneal insufflation, as compared to anesthesia control.

  • An in vitro model fails to demonstrate aerosolization of tumor cells SURGICAL ENDOSCOPY-ULTRASOUND AND INTERVENTIONAL TECHNIQUES Sellers, G. J., Whelan, R. L., Allendorf, J. D., Gleason, N. R., Donahue, J., Laird, D., Bessler, M. D., Treat, M. R. 1998; 12 (5): 436–39

    Abstract

    We investigated the ability of pressurized CO2 gas to aerosolize B16 melanoma (B16) tumor cells in an in vitro model.The experimental apparatus consisted of an 18.9-L plastic cylindrical vessel and a compliant latex pouch was attached to the top. Two 5-mm ports penetrated the vessel; insufflation and desufflation were carried out through them. A culture dish containing 20 million B16 cells in liquid culture media was placed at the base within the container. In the first experiment, the vessel was insufflated with CO2 gas to a static pressure of 15 or 30 mm Hg with the outflow port closed. After 10 min, the outflow port was opened and the gas was desufflated through a collecting device containing sterile culture medium. In a second experiment, a continuous flow of CO2 through the vessel was maintained after a pressure of 15 or 30 mm Hg was established. A total of 10 L CO2 was cycled through the vessel. In both experiments, 24 determinations were carried out at each pressure. Each experimental culture dish was microscopically scanned for 2 weeks for the presence of tumor cells. The third and fourth experiments tested for the presence of aerosolized nonviable tumor cells in the expelled gas. Using the model described above, after 10 mins of 30 mm Hg static pressure, the CO2 gas was expelled directly onto a glass slide and cytofixed. Alternately, after 10 mins at 30 mm Hg static pressure, the gas was expelled through a saline-filled Soluset (Abbott Laboratories), centrifuged, and the residue cytofixed onto a glass slide. Each of the five slides per experiment were examined microscopically for the presence of cells.In the first and second experiments, no cells or growth were observed in any of the 96 experimental dishes. In experiments three and four, no cells were detected on any of the slides.It was not possible with this model to aerosolize tumor cells in a pressurized CO2 environment. Our results suggest that aerosolization of tumor cells is not the mechanism of port site recurrences after laparoscopic surgery for malignant disease.
