Abstract
The evolution of anterior cruciate ligament (ACL) surgery, seemingly circular at times, informs and provides context for past and current controversies in ACL management. The purpose of this systematic review is to objectively summarize the historical course of ACL reconstruction and repair in the United States over the last 40 years. Femoral tunnel drilling and graft selection have evolved dramatically over the last few decades. An initial focus on restoring ACL anatomy was for a period sacrificed for decreased operative morbidity. However, recent developments in operative techniques aim to restore ACL anatomy while also achieving minimal operative morbidity. Despite this historically iterative process, there remains no perfect choice for the treatment of ACL tears. Continued research on ACL repair, anatomic graft placement, graft choice, and augmentation will help our patients over the next generation.

ACL reconstruction with lateral extra-articular tenodesis using a continuous graft: 10-year outcomes of 50 cases. Orthop Traumatol Surg Res 2020; 106:929-935. [PMID: 32534897 DOI: 10.1016/j.otsr.2020.04.007] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 04/17/2020] [Accepted: 04/21/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Persistence of pivot shift is the main problem after isolated intra-articular anterior cruciate ligament (ACL) reconstruction. Adding lateral extra-articular tenodesis (LET) to the ACL procedure increases the knee's stability by controlling rotational laxity. The aim of this study was to evaluate the long-term clinical and radiological outcomes of combined ACL reconstruction with LET using a continuous hamstring graft as a first-line procedure. MATERIAL AND METHODS Fifty patients were reviewed at 10 years postoperative. Subjective outcome scores -IKDC, Lysholm, KOOS and Tegner- were collected. A clinical and radiological assessment was done. The knees' anteroposterior laxity was measured with a rollimeter. RESULTS The mean IKDC subjective score was 85.5, the mean Lysholm score was 90.2 and 80% of patients had a score graded as good or very good. No pivot shift was present in 94% of patients and there was a firm endpoint in the Lachman test in 86% of patients. There was a flexion deficit>5° in 5 patients and an extension deficit of 10° in one patient. Most patients (56%) had resumed their physical activities at the same level as before the surgery. Signs of osteoarthritis were found in 26% of patients (16% were Ahlback stage 1 and 10% were stage 2). There was only one graft failure. These good outcomes are consistent with other published studies on combined ACL-LET. There was neither significant stiffness, nor a higher rate of secondary osteoarthritis relative to ACL reconstruction only, particularly in the lateral tibiofemoral compartment. CONCLUSION Adding primary LET to ACL reconstruction improves control of rotational laxity over time without increasing the complication rate. LEVEL OF EVIDENCE IV, retrospective study without control group.

Clin Biomech (Bristol, Avon) 2018; 60:100-107. [PMID: 30340149 DOI: 10.1016/j.clinbiomech.2018.10.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Revised: 08/24/2018] [Accepted: 10/11/2018] [Indexed: 02/07/2023]
Abstract
The objective of this study was to determine the biomechanical properties of the fascia lata and the effects of three preservation methods: freezing, cryopreservation with dimethylsulfoxide solution and lyophilization; and to compare the effects of low-dose (11 kGy) and normal-dose (25 kGy) gamma-ray sterilization versus no irradiation. 248 samples from 14 fasciae latae were collected. Freezing samples were frozen at -80 °C. Cryopreservation with dimethylsulfoxide solution samples were frozen with 10 cl dimethylsulfoxide solution at -80 °C. Lyophilization samples were frozen at -22 °C and lyophilized. Each preservation group were then randomly divided into 3 irradiation groups. The cryopreservation with dimethylsulfoxide solution samples had significantly worse results in all 3 irradiation conditions. Young's modulus was lower for the freezing samples (p < 0.001) and lyophilization samples groups (p < 0.001). Tear deformation was lower for the freezing samples (p = 0.001) and lyophilization samples groups (p = 0.003), as was stress at break (p < 0.001 and p < 0.001). Taking all preservation methods together, samples irradiated at 25 kGy had worse results than the 0 kGy and 11 kGy groups in terms of Young's modulus (p = 0.007 and p = 0.13) and of stress at break (p = 0.006 and p = 0.06). The biomechanical properties of fascia lata allografts were significantly worse under dimethylsulfoxide cryopreservation. The deleterious effects of irradiation were dose-dependent.

Abstract
Joint injury has been recognized as a potent risk factor for the onset of osteoarthritis. The vast majority of studies using imaging technology for longitudinal assessment of patients following joint injury have focused on the injured knee joint, specifically in patients with anterior cruciate ligament injury and meniscus tears where a high risk for rapid onset of post-traumatic osteoarthritis is well known. Although there are many imaging modalities under constant development, magnetic resonance (MR) imaging is the most important instrument for longitudinal monitoring after joint injury. MR imaging is sensitive for detecting early cartilage degeneration and can evaluate other joint structures including the menisci, bone marrow, tendons, and ligaments which can be sources of pain following acute injury. In this review, focusing on imaging following acute knee trauma, several studies were identified with promising short-term results of osseous and soft tissue changes after joint injury. However, studies connecting these promising short-term results to the development of osteoarthritis were limited which is likely due to the long follow-up periods needed to document the radiographic and clinical onset of the disease. Thus, it is recommended that additional high quality longitudinal studies with extended follow-up periods be performed to further investigate the long-term consequences of the early osseous and soft tissue changes identified on MR imaging after acute knee trauma.

Abstract
BACKGROUND Knee osteoarthritis after anterior cruciate ligament (ACL) injury has previously been reported. However, there has been no meta-analysis reporting the development and progression of osteoarthritis. PURPOSE We present the first meta-analysis reporting on the development and progression of osteoarthritis after ACL injury at a minimum mean follow-up of 10 years, using a single and widely accepted radiologic classification, the Kellgren & Lawrence classification. STUDY DESIGN Meta-analysis. METHOD Articles were included for systematic review if they reported radiologic findings of ACL-injured knees and controls using the Kellgren & Lawrence classification at a minimum mean follow-up period of 10 years. Appropriate studies were then included for meta-analysis. RESULTS Nine studies were included for systematic review, of which 6 studies were further included for meta-analysis. One hundred twenty-one of 596 (20.3%) ACL-injured knees had moderate or severe radiologic changes (Kellgren & Lawrence grade III or IV) compared with 23 of 465 (4.9%) uninjured ACL-intact contralateral knees. After ACL injury, irrespective of whether the patients were treated operatively or nonoperatively, the relative risk (RR) of developing even minimal osteoarthritis was 3.89 (P < .00001), while the RR of developing moderate to severe osteoarthritis (grade III and IV) was 3.84 (P < .0004). Nonoperatively treated ACL-injured knees had significantly higher RR (RR, 4.98; P < .00001) of developing any grade of osteoarthritis compared with those treated with reconstructive surgery (RR, 3.62; P < .00001). Investigation of progression to moderate or severe osteoarthritis (grade III or IV only) after 10 years showed that ACL-reconstructed knees had a significantly higher RR (RR, 4.71; P < .00001) compared with nonoperative management (RR, 2.41; P = .54). It was not possible to stratify for return to sports among the patients undergoing ACL reconstruction. CONCLUSION Results support the proposition that ACL injury predisposes knees to osteoarthritis, while ACL reconstruction surgery has a role in reducing the risk of developing degenerative changes at 10 years. However, returning to sports activities after ligament reconstruction may exacerbate the development of arthritis.

Abstract
Acute anterior cruciate ligament (ACL) tears are most frequently sustained by young, physically active individuals. ACL injuries are seen at high incidence in adolescents and young adults performing sports and occupational activities that involve pivoting. Young women participating in pivoting sports have a 3 to 5 times higher risk of ACL injury than men. Studies show that ACL injury increases osteoarthritis (OA) risk with symptomatic OA appearing in roughly half of individuals 10-15 years later. Because the majority of patients sustaining acute ACL tears are younger than 30, this leads to early onset OA with associated pain and disability during premium work and life growth years between ages 30 and 50. Effective strategies to prevent ACL injury and to reduce subsequent OA risk in those sustaining acute ACL tears are needed.

Abstract
OBJECTIVE To analyze the clinical outcomes of arthroscopic anterior cruciate ligament (ACL) reconstruction with irradiated bone-patellar tendon-bone (BPTB) allograft compared with non-irradiated allograft and autograft. METHODS All BPTB allografts were obtained from a single tissue bank and the irradiated allografts were sterilized with 2.5 mrad of irradiation prior to distribution. A total of 68 patients undergoing arthroscopic ACL reconstruction were prospectively randomized consecutively into one of the two groups (autograft and irradiated allograft groups). The same surgical technique was used in all operations done by the same senior surgeon. Before surgery and at the average of 31 months of follow-up (ranging from 24 to 47 months), patients were evaluated by the same observer according to objective and subjective clinical evaluations. RESULTS Of these patients, 65 (autograft 33, irradiated allograft 32) were available for full evaluation. When the irradiated allograft group was compared to the autograft group at the 31-month follow-up by the Lachman test, the anterior drawer test (ADT), the pivot shift test, and KT-2000 arthrometer test, statistically significant differences were found. Most importantly, 87.8% of patients in the autograft group and just only 31.3% in the irradiated allograft group had a side-to-side difference of less than 3 mm according to KT-2000. The failure rate of the ACL reconstruction with irradiated allograft (34.4%) was higher than that with autograft (6.1%). The anterior and rotational stabilities decreased significantly in the irradiated allograft group. According to the overall International Knee Documentation Committee (IKDC), functional and subjective evaluations, and activity level testing, no statistically significant differences were found between the two groups. Besides, patients in the irradiated allograft group had a shorter operation time and a longer duration of postoperative fever. When the patients had a fever, the laboratory examinations of all patients were almost normal. Blood routine was normal, the values of erythrocyte sedimentation rate (ESR) were 5~16 mm/h and the contents of C reactive protein (CRP) were 3-10 mg/L. CONCLUSION We conclude that the short term clinical outcomes of the ACL reconstruction with irradiated BPTB allograft were adversely affected. The less than satisfactory results led the senior authors to discontinue the use of irradiated BPTB allograft in ACL surgery and not to advocate using the gamma irradiation as a secondary sterilizing method.

Abstract
BACKGROUND This is a systematic review of studies on the prevalence of osteoarthritis in the tibiofemoral joint more than 10 years after an anterior cruciate ligament injury, the radiologic classification methods used, and risk factors for development of knee osteoarthritis. METHODS A systematic search was performed in PubMed, EMBASE, and AMED. Inclusion criteria were studies involving patients with anterior cruciate ligament injury, either isolated or combined with medial collateral ligament or meniscal injury and either surgically or nonsurgically treated, and a minimum 10-year follow-up with radiologic assessment. Methodological quality was evaluated using a modified version of the Coleman methodology score. RESULTS Seven prospective and 24 retrospective studies were included. The mean modified Coleman methodology score was 52 of 90. Reported prevalence of knee osteoarthritis for subjects with isolated anterior cruciate ligament injury was between 0% and 13%. For subjects with anterior cruciate ligament and additional meniscal injury, the prevalence varied between 21% and 48%. Seven different radiologic classification systems were used in the studies. Only 3 studies reported reliability results for the radiologic assessments. The most frequently reported risk factor for development of knee osteoarthritis was meniscal injury. CONCLUSION This systematic review suggests that the prevalence rates of knee osteoarthritis after anterior cruciate ligament reconstruction reported by previous reviews have been too high. The highest rated studies reported low prevalence of knee osteoarthritis for individuals with isolated anterior cruciate ligament injury (0%-13%) and a higher prevalence of knee osteoarthritis for subjects with combined injuries (21%-48%). Overall, the modified Coleman methodology score was low for the included studies. No universal methodological radiologic classification method exists, making comparisons of the studies and stating firm conclusions on the prevalence of knee osteoarthritis more than 10 years after anterior cruciate ligament injury difficult.

Abstract
The effect of using gamma irradiation to sterilize bone-patellar tendon-bone (BPTB) allograft on the clinical outcomes of anterior cruciate ligament (ACL) reconstruction with irradiated allograft remains controversial. Our study was aimed to analyze the clinical outcomes of arthroscopic ACL reconstruction with irradiated BPTB allograft compared with non-irradiated allograft and autograft. All BPTB allografts were obtained from a single tissue bank and the irradiated allografts were sterilized with 2.5 Mrad of irradiation prior to distribution. A total of 102 patients undergoing arthroscopic ACL reconstruction were prospectively randomized consecutively into three groups. The same surgical technique was used in all operations done by the same senior surgeon. Before surgery and at the average of 31 months follow-up (range 24-47 months) patients were evaluated by the same observer according to objective and subjective clinical evaluations. Of these patients, 99 (autograft 33, non-irradiated allograft 34, irradiated allograft 32) were available for full evaluation. When compared the irradiated allograft group to non-irradiated allograft group or autograft group at 31 months follow-up by the Lachman test, ADT, pivot shift test and KT-2000 arthrometer testing, statistically significant differences were found. Most importantly, 87.8% of patients in the Auto group, 85.3% in the Non-Ir-Auto group and just only 31.3% in the Ir-Allo group had a side-to-side difference of less than 3 mm according to KT-2000. The failure rate of the ACL reconstruction with irradiated allograft (34.4%) was higher than that with autograft (6.1%) and non-irradiated allograft (8.8%). The anterior and rotational stability decreased significantly in the irradiated allograft group. According to the overall IKDC, functional, subjective evaluations and activity level testing, no statistically significant differences were found between the three groups. However, there was a trend that the functional and activity level decreased and the patients felt uncomfortable more often in the irradiated allograft group. The statistical analysis showed no significant difference between the non-irradiated allograft group and the autograft group according to the aforementioned evaluations, except that patients in the allograft group had a shorter operation time and a longer duration of postoperative fever. When comparing the postoperative duration of fever of the two allograft groups, there was also a trend that the irradiated allograft group was longer than the non-irradiated allograft group, but no significant difference was found. When the patients had a fever, the laboratory examinations of all patients were almost normal (Blood routine was normal, the values of ESR were 5 - 16 mm/h, CRP were 3 - 10 mg/l). On the basis of our study, we concluded that patients undergoing ACL reconstruction with BPTB non-irradiated allograft or autograft had similar clinical outcomes. Non-irradiated BPTB allograft is a reasonable alternative to autograft for ACL reconstruction. While the short term clinical outcomes of the ACL reconstruction with irradiated BPTB allograft were adversely affected with an increased failure rate. The less than satisfactory results led the senior authors to discontinue the use of irradiated BPTB allograft in ACL surgery and not to advocate that gamma irradiation be used as a secondary sterilizing method. Further research into alternatives to gamma irradiation is needed.

Abstract
PURPOSE To evaluate the long-term outcomes following arthroscopic-assisted anterior cruciate ligament (ACL) reconstruction using fresh-frozen allogeneic tendon. METHODS Sixty-one athletically active patients (mean age at surgery, 20.9 years) who had arthroscopic-assisted ACL reconstruction using fresh-frozen free tendon allograft underwent physical examination, instrumented laxity measurement, radiographs, and thigh muscle strength at 10 to 14 years (mean, 11.5) postoperatively, and these data were compared with results of similar measurements obtained at 2 years postoperatively. RESULTS Lachman test and pivot shift test were maintained as negative in 53 (87%) and 52 (85%) patients at follow-up, respectively. Quantitative measurements using the KT-2000 knee arthrometer showed 1.6 +/- 1.3 (mean +/- SD) mm in the side-to-side difference, and no more than 3 mm in 56 patients (92%) at final follow-up. All but one was assessed as normal or nearly normal by International Knee Documentation Committee score. Patient activity level was decreased at the long-term follow-up, but this change was mainly associated with changes in social context (e.g., graduation from school) rather than with knee limitations. None of the patients experienced deep infection or graft rejection. Degenerative joint disease on radiographs was seen in 13 out of 15 patients (87%) whose menisci had been excised, whereas it was observed in 12 out of 46 (26%) whose menisci had been preserved. CONCLUSIONS A series of 61 patients with fresh-frozen bone plug-free tendon allografts using a 2-incision technique for arthroscopic ACL reconstruction results in long-term knee stabilization and functioning among young active individuals while simultaneously avoiding graft harvest site morbidity. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Allografts have recently become increasingly popular for anterior cruciate ligament reconstruction (ACLR) in the United States even though many studies have shown high allograft failure rates (Gorschewsky et al. in Am J Sports Med 33:1202, 2005; Pritchard et al. in Am J Sports Med 23:593, 2005; Roberts et al. in Am J Sports Med 19:35, 2006) and no meta-analysis or systematic review of allograft clinical stability rates in comparison to autog rafts has previously been performed. We hypothesized that allografts would demonstrate overall lower objective stability rates compared to autografts. To test this hypothesis we performed a meta-analysis of autograft and allograft stability data. A pubmed literature search of all allograft series in humans published in English was performed. Articles were then bibliographically cross-referenced to identify additional studies. Series inclusion criteria were arthrometric follow-up data using at least 30 lb or maximum manual force, stratified presentation of stability data and minimum two-year follow-up. Twenty allograft series were thus selected and compared to a previously published data set of all BPTB and Hamstring (HS) autograft ACLR series using the same study inclusion criteria and analytic and statistical methodology. IKDC standards of 0-2 mm (normal) and >5 mm (abnormal) side-to-side differences were adopted to compare studies. Normal stability for all autografts was 72 versus 59% for all allografts (P < 0.01). Abnormal stability was 5% for all autografts versus 14% for all allografts (P < 0.01). Bone-patellar-tendon-bone (BPTB) autograft normal stability was 66% versus 57% for BPTB allografts (P < 0.01). Abnormal BPTB autograft stability was 6 versus 16% for BPTB allograft. Hamstring autograft normal or abnormal stability rates were 77% and 4% and were compared to soft tissue allografts as a group which were 64% and 12% (P < 0.01). This is the first meta-analysis comparing autograft to allograft stability in ACLR. Allografts had significantly lower normal stability rates than autografts. The allograft abnormal stability rate, which usually represents graft failure, was significantly higher than that of autografts: nearly three times greater. It would therefore appear that autografts are the graft of choice for routine ACLR with allografts better reserved for multiple ligament-injured knees where extra tissue may be required.

Abstract
With an ageing population, increasing numbers of women are presenting with pelvic floor disorders. The lifetime risk of undergoing prolapse or incontinence surgery in the USA is 1 in 11. With a recognized reoperation rate exceeding 30% for prolapse surgery, attempts are being made to improve our primary surgical outcomes. The introduction of synthetic and biological prostheses have been proposed to reduce recurrence rates whilst maintaining vaginal capacity and coital function. The role of synthetic prostheses is well established for use in continence surgery in the form of midurethral slings and for abdominal sacrocolpopexy to correct vault prolapse. However, postoperative morbidity-specifically the risk of mesh erosion-has limited their use for vaginal prolapse surgery. Biological prostheses have been introduced to offer an alternative for use in these repairs. While these grafts largely obviate the problem of erosion there are concerns regarding longevity, and only short-term outcome data are currently available. The role of prosthetics in pelvic floor surgery is an evolving and controversial field. Current and future research should be directed at evaluating the safety and efficacy of specific products and comparison of subjective and objective outcome parameters to standard surgical techniques for pelvic organ prolapse.

Abstract
The purpose of this study was to evaluate the histologic response of human cadaveric fascia lata after vaginal implantation. Freeze-dried, gamma-irradiated cadaveric fascia lata from three lots was implanted between the rectovaginal membrane and vaginal epithelium in New Zealand white rabbits. Rabbits were killed at 2, 4, 8, and 12 weeks after implantation. At necropsy, gross findings were described and specimens for routine cultures were taken. Histologic evaluation determined graft integrity, neovascularization, inflammatory response, and host tissue incorporation. Nine rabbits were available for histologic analysis and 14 for gross and microbiologic analysis. Vaginal erosions occurred with three grafts. The remainder were adherent to the surrounding tissues. Erosion was associated with bacterial colonization of the graft. Autolysis of one graft occurred at 4 weeks. Over time, the inflammatory response decreased and neovascularization increased; by 12 weeks, the graft collagen was replaced by host collagen. Cadaveric fascia lata serves as scaffolding for host tissue incorporation with replacement by host collagen.

Abstract
BACKGROUND No consensus exists on the amount of tension that should be applied to anterior cruciate ligament grafts to best facilitate graft incorporation and re-create normal knee mechanics. HYPOTHESIS Differences in initial graft tension will affect postoperative knee stability. STUDY DESIGN Prospective, randomized, double-blind clinical trial. METHODS Forty-nine patients undergoing bone-patellar tendon-bone autograft anterior cruciate ligament reconstruction by a single surgeon were randomized into high-tension (n = 27) and low-tension (n = 22) groups. Grafts were set at 90 N or 45 N. Arthrometric measurements (KT-1000 arthrometer manual maximum) of anterior tibial displacement and knee range of motion were made before surgery and at 1 week and an average of 20 months after surgery. Knee outcome scores were collected before and after surgery, and a single-leg hop test was also performed at final follow-up. RESULTS After anterior cruciate ligament reconstruction, anterior tibial displacement was significantly greater in the patients in the low-tension group (P < .05). The side-to-side difference in anterior tibial displacement in the high-tension and low-tension groups was 1.1 +/- 1.7 mm versus 2.4 +/- 2.4 mm 1 week after surgery and 2.2 +/- 1.6 mm versus 3.0 +/- 2.2 mm at follow-up. Five patients had abnormal anterior tibial displacement (>5 mm side-to-side difference), and all were in the low-tension group (P <.05). Knee outcome scores improved with surgery (P <.01), with similar results for low-tension and high-tension groups. Hop test deficits were not different between groups. CONCLUSIONS Initial graft tension affects the restoration of knee stability. A graft tension of 45 N was not sufficient for restoring knee stability.

Abstract
PURPOSE We determined changes in tensile properties after vaginal implantation of human cadaveric fascia lata. MATERIALS AND METHODS Baseline tensile properties were determined for freeze-dried, gamma irradiated human cadaveric fascia lata from 3 separate lots. Fascial strips (2 x 0.5 cm.) from 2 lots were implanted between the rectovaginal membrane and vaginal mucosa in New Zealand white rabbits. The strips were excised en bloc 12 weeks after implantation. Tensile property measurements were repeated and compared with pre-implantation values. RESULTS Pre-implantation interlot and intralot variability in baseline tensile properties was significant. After implantation there was an approximate 90% decrease in tensile strength from baseline values. There was no gross evidence of graft autolysis. CONCLUSIONS The decrease in tensile strength of cadaveric fascial graft was significant after implantation in this model.

Abstract
PURPOSE The study goal was to determine the results of allograft anterior cruciate ligament (ACL) reconstruction in patients over 40 years old at a minimum of 24 months follow-up (mean, 59.7 months; range, 24 to 110 months). TYPE OF STUDY Retrospective review. METHODS The records of 57 consecutive patients (mean age at surgery, 45.0 years; range, 40.2 to 60.8 years) were reviewed retrospectively. Nine patients who had undergone either prior ACL reconstruction, extra-articular reinforcement of the intra-articular procedure, or subsequent upper tibial osteotomy were eliminated. One patient was lost to follow-up. Of the remaining 47 patients (48 knees), 29 (62%) were men, and 18 (38%) were women. Twenty-eight of the 47 study patients (60%) were available for clinical interview consisting of physical examination, radiographs, and functional testing. Twenty-seven of these patients also underwent KT-1000 measurement, and 26 underwent Biodex evaluation. The remaining 19 patients were interviewed by telephone. RESULTS At follow-up, Lachman, anterior drawer, and pivot shift tests were 0 or 1 in 27 (96%) of 28 patients. Differences between the index and contralateral legs as measured by KT-1000 at 20 lb of force were 0 to 2 mm in 22 of 27 patients (81%) and 3 to 5.5 mm in 5 patients (19%). None had a side-to-side difference greater than 5.5 mm. Based on the International Knee Documentation Committee activity classification system, 26 (55%) of 47 patients achieved the same or higher grade of activity postoperatively as they had preinjury. CONCLUSIONS Results of ACL reconstruction in patients over 40 compare favorably with those observed in younger patients. Age should not be a limiting factor in choosing surgical reconstruction to treat functional instability in the ACL-deficient patient.

Abstract
PURPOSE OF REVIEW Uterovaginal prolapse and urinary incontinence are common problems whose pathogenesis remains unclear. As life expectancy increases, significantly greater numbers of women will present with pelvic floor prolapse and incontinence requiring surgical intervention. Currently, the lifetime risk of undergoing prolapse or continence surgery in the USA is one in 11, and up to 30% of patients will require repeat prolapse and 10% repeat continence surgery. In an attempt to improve surgical outcomes and to preserve vaginal capacity and coital function, a number of synthetic and biological prostheses have been developed. This review aims to look at the controversies that exist as the 'ideal' prosthetic material is developed. RECENT FINDINGS The recent literature has reflected the increasing interest in the use of biological prostheses (Allograft/Xenograft) and synthetic absorbable meshes. There has been a focus on the risk factors for erosion seen with the use of synthetic non-absorbable material and a review of techniques for the reduction and management of this complication. The advent of mesh placement in minimally invasive continence surgery (tension-free vaginal tape, intravaginal sling, and Supra Public ARC) is now seeing surgical success to 5 years, but the reporting of complications remains inconsistent. SUMMARY The use of prosthetics in pelvic floor and continence surgery is an evolving field. Further randomized controlled trials are required to evaluate the role of both biological and synthetic prostheses in reconstructive surgery, to determine which type of prosthesis is most suitable for specific procedures. Prosthetic reinforcement should not be used to replace good surgical techniques.

Abstract
OBJECTIVES Fascia lata allografts are commonly used in urogynecologic procedures. Functional failure of several grafts has occurred, and such failure has been recognized as a materials problem in 12 patients. STUDY DESIGN Twelve patients with failure of an initial urogynecologic procedure performed with irradiated and freeze-dried donor fascia lata grafts underwent reoperation. Portions of the implanted fascia lata grafts could be retrieved in 7 cases. Graft specimens underwent histologic processing followed by hematoxylin and eosin staining. RESULTS Histopathologic analyses of the retrieved material demonstrated several ongoing processes in the failed grafts. A few grafts showed areas of ideal remodeling. Most grafts, however, showed areas of disorganized remodeling and areas of graft degeneration. Evidence of immune reaction to the graft was observed in some cases. CONCLUSION The high materials failure rate associated with the use of irradiated and freeze-dried donor fascia lata grafts suggests that such tissue should not be used for urogynecologic procedures.

Abstract
OBJECTIVES To report our experience of using freeze-dried irradiated fascia lata allografts for suburethral sling procedures. PATIENTS AND METHODS Between December 1996 and September 1998, 35 patients (mean age 60.25 years, range 37-79) underwent suburethral sling placement with fascia allograft. These patients were reviewed, with the findings at the time of any surgical re-exploration. Eleven (31%) had undergone prior surgery for genuine stress incontinence and 32 (91%) had a preoperative diagnosis of intrinsic sphincter deficiency. RESULTS On re-operation for persistent or recurrent stress incontinence, the allograft was present but grossly degenerated in two (6%) patients and completely absent in five (14%) patients. Histology of a retrieved graft fragment showed both fibroblast proliferation and degeneration within the graft. CONCLUSION The use of freeze-dried, irradiated fascia lata for suburethral sling procedures was associated with a material failure rate of >/=20%. We caution against its use in this setting.

Abstract
In this prospective study we investigated 70 patients with chronic anterior instability who underwent anterior cruciate ligament reconstruction with a Dacron prosthesis. Fifty-five (79%) patients could be followed up at a mean of 9 years. Within the follow-up time, 44% (29 of 66) of the prostheses were diagnosed as ruptured; the annual rupture frequency was 5%. Second reconstructions were performed for 20 patients (29%), 5 patients had third reconstructions, and 9 patients wanted no further surgical treatment. Fifty-two patients (74% of the original group) underwent radiographic examination. Eighty-three percent (43) of these patients had radiographic changes in the operated knee, and 40% (21 of 52) had joint space reduction up to 50%. The rate of radiographically detected osteoarthritis was increased 10 times compared with the normal knee. Patients with medical instability and patients older than 30 years at the initial operation had more severe osteoarthritic changes. Based on the functional results of the patients with a ligament in place after 9 years, only 14% (10) of the original group had acceptable stability and knee function.
