Evaluating the sociodemographic, anthropometric and lifestyle parameters, depression, quality of life, cognitive status, physical activity, and Mediterranean diet adherence of older adults in pre- and post-Covid-19 periods: a comparative cross-sectional study.

Ojective: Covid-19 pandemic has exerted deleterious effects on several aspect of mental health worldwide. The detrimental medical complications, the increased prevalence of morbidity and the rapid international spread of Covid-19 have resulted in urgent public health concerns and political measures across the world. This comparative, cross-sectional study aims to assess the changes that were established in sociodemographic, anthropometric and lifestyle parameters and several aspects of mental health of older adults due to Covid-19 pandemic by comparing the pre-Covid period with the post-Covid period. Methods: Qualified questionnaires were applied for assessing the prevalence of depression, quality of life, cognitive status, and Mediterranean Diet (MD) adherence, as well as sociodemographic, anthropometric and lifestyle parameters in 3388 older adults in the pre- and post-Covid period. Results: Covid-19 pandemic independently affected type of residence, smoking habits, BMI and WHR status, risk of depression, quality of life, cognitive status, physical activity levels, and MD adherence. Conclusions: Covid -19 pandemic has exerted persistent detrimental effects on daily quality of life and mental health of older adults in the post-Covid period. Future strategies and public policies should develop healthcare programs to provide psychological and nutritional counseling and support to older adults to minimize the detrimental effects of Covid pandemic.

Similarities and Differences in the Management of Patients with Osteoporotic Vertebral Fractures and Those with Rebound-Associated Vertebral Fractures Following Discontinuation of Denosumab.

Rebound-associated vertebral fractures (RVFx) following denosumab discontinuation are typically multiple, are commonly associated with acute sharp pain, increase the risk of imminent fractures, and are pathogenetically different from common osteoporotic vertebral fractures (VFx). A clinically relevant question is whether patients with RVFx should be managed differently from patients with osteoporotic VFx. To address this question, we performed a systematic search of the PubMed database, and we reviewed current evidence on the optimal management of patients with RVFx. For pain relief of patients with RVFx, potent analgesics, often opioids, are essential. Information on the effectiveness of braces in these patients is scarce. Vertebroplasty and kyphoplasty are strongly contraindicated as they confer a substantial risk for new VFx. Exercise may be helpful, but again evidence is lacking. In contrast to patients with osteoporotic VFx, in whom initial treatment with bone-forming agents is recommended, patients with RVFx should initiate treatment with potent antiresorptives. To summarize, patients who have sustained RVFx following denosumab discontinuation are at a very high risk for new fractures, especially VFx. The management of such patients requires a multidisciplinary approach that should not be restricted to pain relief and administration of antiosteoporotic medication, but should also include back protection, early mobilization, and appropriate exercise.

Converting 1st metatarsophalangeal joint fusion to interposition arthroplasty. Mid-term results of a case series.

BACKGROUND: Fusion of the first metatarsophalangeal (MTP) joint has been considered as the gold standard for treatment of advanced hallux rigidus. The main disadvantage is the restriction of movement which may not be as favorable as anticipated by several patients. The purpose of this study was to report clinical and functional outcomes on patients who were treated with interposition arthroplasty after a 1st MTP joint fusion which had not fulfilled their expectations. METHODS: Between 2009 and 2014, 11 patients who were not satisfied by 1st MTP joint fusion for hallux rigidus, underwent a conversion to interposition arthroplasty. After removal of hardware, the fusion was taken down by removal of a bone block from the fused joint. A fascia lata graft was interposed. Intraoperative and postoperative complications, range of motion of the first MTP joint, length of first ray, and patients' satisfaction were recorded as the primary outcomes. RESULTS: Mean age was 34 years (range, 24-42 y). The mean ± SD AOFAS/H/MTP/IP score was 61 ± 5.5 preoperatively, 90.5 ± 4.5 at one year and 92 ± 4 at five years postoperatively (p < 0.001). The mean ± SD VAS-FA score was 91 ± 3.5 preoperatively, 94.5 ± 2.5 at one year and 95 ± 2.5 at five years postoperatively (p > 0.05). Mean ROM at the final follow-up was 58° ± 5° of dorsiflexion and 27° ± 4° of plantarflexion. No inter- or postoperative complications were encountered. The length of the hallux was decreased by a mean of 1.5 mm (range, 1-2.5 mm). All patients were satisfied with the overall outcome, walking ability and shoe-wear convenience and graded their condition as excellent (9 cases) or good (2 cases). CONCLUSIONS: Converting a 1st MTP joint fusion to interposition arthroplasty with a fascia lata allograft could be a safe alternative with promising results in selected cases especially in relatively young and athletic population. LEVEL OF EVIDENCE: Level IV retrospective case series.

Above-Knee Amputation After Total Knee Replacement Infection: The Unfortunate End of an Odyssey.

Total knee replacement is the gold standard for the surgical treatment of late-stage symptomatic knee osteoarthritis when conservative measures have not alleviated the problem. However, as with any surgery, there are potential dangers and complications. Of these, infection is one of the most severe and may lead to life-changing outcomes for the patient. In this case report, a patient with a history of infected primary total knee arthroplasty and numerous attempts to eradicate the patient's infection is presented. After two unsuccessful two-stage revisions, and although arthrodesis was discussed and suggested, an above-knee amputation was finally applied to our patient.

Simultaneous Bilateral Insufficiency Femoral Fractures After Long-Term Alendronate Treatment: A Lesson Not Yet Learned.

Bisphosphonates have recently been used as a first-line treatment for osteoporosis. However, prolonged bisphosphonate use may be associated with insufficiency and atypical femoral fractures. In this case report, we present a patient with simultaneous bilateral insufficiency femoral fractures after using alendronate for 11 years, which were treated surgically. Our patient also had a history of a previous right femoral atypical fracture eight years before the latest ones, while on 3-year alendronate treatment. To our knowledge, it is the first patient reported with three atypical - insufficiency fractures covering all the anatomical areas of the proximal half of the femur after long-term bisphosphonate treatment.

Post-traumatic missing talus: Staged allograft interposition and fusion. Should we fuse the "talo-navicular" joint?

Complete talar dislocation-extrusion is an uncommon sequela of high-energy trauma. When the talus is unavailable for reimplantation, a staged treatment plan with the use (a) of an antibiotic cement spacer, followed by (b) tibiotalocalcaneal fusion with bone allograft interposition, may ensure a good clinical outcome.

The effect of pharmacological cessation and restoration of menstrual cycle on bone metabolism in premenopausal women with endometriosis.

INTRODUCTION: GnRH-analogs induce bone loss. We aimed to investigate the effects of goserelin-induced menstrual cessation (MC) and subsequent menstrual restoration (MR) on bone metabolism (BM). METHODS: In this prospective cohort study, premenopausal women (PMW) with histologically verified endometriosis (n = 21) received goserelin monthly for 6 months (6 m) resulting in MC and were followed up for another 6 m after MR (12 m). Age- and BMI-matched healthy PMW (n = 20) served as controls for bone mineral density (BMD) measurements. The primary endpoint was changes in lumbar spine (LS)-BMD at 6 m and 12 m; Secondary endpoints were changes in femoral neck (FN)-BMD, bone turnover markers (P1NP and CΤx), sclerostin, and expression of bone-related circulating microRNAs (miRNAs) at 6 m and 12 m. RESULTS: Goserelin-induced MC reduced LS- and FN-BMD at 6 m (both p < 0.001). From 6 m to 12 m, LS-BMD increased (p < 0.001) but remained below baseline values (p = 0.012), whereas FN-BMD remained stable (p = 1.000). CTx and P1NP levels increased at 6 m (both p < 0.001) and decreased at 12 m (p < 0.001 and p = 0.013, respectively), while CTx (p = 1.000) alone and not P1NP (p = 0.020) returned to baseline. Sclerostin levels did not change. Relative expression of miRNAs targeting RUNX 2 and beta-catenin was significantly downregulated at 6 m compared to baseline (p < 0.001), while the expression of miRNAs targeting osteoblast and osteoclast function at both directions demonstrated a robust increase (up to 400fold) at 12 m (p < 0.001). CONCLUSIONS: Six months of goserelin-induced MC lead to significant bone loss associated with increased bone turnover and changes in the expression of bone-related miRNAs, changes that are only partially reversed at 6 m after MR.

Does Bone Regrow After Notchplasty in ACL Reconstruction? A Prospective Computed Tomography Study With 2-Year Follow-up.

BACKGROUND: During notchplasty in anterior cruciate ligament (ACL) reconstruction, bone is excised from the lateral and roof area of the notch to widen the intercondylar space and avoid notch-graft impingement in extension. There are concerns that bone regrowth of the area will cause narrowing and increase the risk of complications. PURPOSE: To determine the possibility of late narrowing of the notch after notchplasty using computed tomography (CT) analysis. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Measurements were performed on CT scans (axial and sagittal planes with knee in extension) in patients who had undergone single-bundle anatomic ACL reconstruction using hamstring graft. Two axial image levels were used: at the anterior outlet and the anterior one-eighth level of the notch. The maximum notch height and width, the notch width at one-third and two-thirds of the preoperative notch midwidth height, the maximum condylar width, and the surface area of the lateral half of the notch were measured preoperatively and at 1 week and 2 years postoperatively. RESULTS: Included were 20 consecutive patients (mean ± standard deviation age, 28 ± 7.3 years; follow-up, 24.2 ± 3.3 months). At the anterior notch outlet, the maximum notch width increased by 1.9 ± 1.7 mm at 1 week postoperatively and narrowed by 0.3 ± 1.1 mm at the final follow-up, while the maximum notch height increased by 1.7 ± 1.9 mm and narrowed by 0.8 ± 1.8 mm, respectively. At one-eighth of the roof length, the maximum notch width increased by 1.1 ± 1.7 mm at 1 week postoperatively and narrowed by 0.1 ± 1.1 mm at the final follow-up, and the maximum notch height increased by 1.2 ± 1.5 mm and narrowed by 0.5 ± 1.5 mm, respectively. All differences were statistically significant when comparing the pre- to the immediate postoperative measurements, and they were nonsignificant when comparing the immediate postoperative to the final follow-up measurements. The same applied for the ratio of maximum notch width to maximum condylar width, indicating no postoperative narrowing of the notch. CONCLUSION: Notch size-shape after a 2-mm notchplasty did not change significantly in stable knees during the first 2 years after anatomic ACL reconstruction. Surgeons should consider performing this adjuvant technique when there is notch-graft impingement during surgery.

Posterior shoulder dislocation with reverse Hill-Sachs lesion. A technical note and report of two cases.

Posterior shoulder dislocation (PSD) with a reverse Hill-Sachs lesion is a rare injury with challenging management. This article is a technical note, describing the combination of both, modified McLaughlin procedure with posterior Bankart repair, for the surgical treatment of traumatic PSD associated with a substantial reverse Hill-Sachs lesion. Two patients with mid-term follow-up are presented. Approaching and repairing both sides of the joint, balance and congruency are restored, the humeral head is centralized in the glenoid and the patient starts early mobilization and rehabilitation safely.

Osteochondral Autologous Transplantation Versus Dorsal Closing Wedge Metatarsal Osteotomy for the Treatment of Freiberg Infraction in Athletes: A Randomized Controlled Study With 3-Year Follow-up.

BACKGROUND: Dorsiflexion closing wedge metatarsal osteotomy (DCWMO) has been considered the traditional treatment of Freiberg disease. Several case reports presented osteochondral autologous transplantation (OAT) as an alternative treatment. PURPOSE/HYPOTHESIS: The purpose was to compare the results of DCWMO versus OAT for the treatment of Freiberg infraction in an athletic population. It was hypothesized that OAT was superior to DCWMO regarding functional outcomes, pain, and the time that the athletes returned to training and to previous sport level. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: Between 2008 and 2013, 27 consecutive patients with Freiberg disease were randomly assigned to either the DCWMO group (14 patients) or the OAT group (13 patients). The primary outcomes collected were as follows: postoperative complications, range of motion of the metatarsophalangeal joint, length of the metatarsal, function of the foot (measured with the American Orthopaedic Foot and Ankle Society-lesser metatarsophalangeal-interphalangeal [AOFAS-LMI] score), and pain (assessed with the visual analog scale-foot and ankle score). RESULTS: Mean follow-up was 46 months (range, 36-60 months). The mean ± SD AOFAS-LMI score in the DCWMO group was 63.4 ± 14.4 preoperatively, 81.8 ± 6.6 at 1 year postoperatively, and 84.4 ± 5.6 at 3 years postoperatively, while in the OAT group, it was 62.8 ± 14, 89.9 ± 7.1, and 92 ± 6.9, respectively (P < .001). The differences in the AOFAS-LMI scores favoring the OAT group at 1 and 3 years reached statistical but not clinical significance. The mean visual analog scale-foot and ankle score was improved significantly from 48.1 ± 11.5 to 91.8 ± 9.5 in the DCWMO group and from 49.9 ± 10.9 to 95.4 ± 4.4 in the OAT group. There was a shortening of the metatarsals by a mean 1.9 ± 0.5 mm in the DCWMO group, as opposed to a metatarsal lengthening of 0.2 ± 0.1 mm in the OAT group. In the OAT group, patients were able to start training at 6 ± 1 weeks (P < .001) and return to full sport action at 10 ± 2.5 weeks (P < .05), while in the DCWMO group, the time was 8 ± 1.5 and 13 ± 2.5 weeks, respectively. CONCLUSION: The authors concluded that OAT is equal to DCWMO. Acceptable clinical results were reported, as well as very low morbidity and early return to sport activities. That makes the OAT procedure a safe, effective, and optimal treatment for an athletic population experiencing Freiberg infraction.

Efficacy of Pharmacological Therapies for Adhesive Capsulitis of the Shoulder: A Systematic Review and Network Meta-analysis.

BACKGROUND: Several pharmacological interventions are used for the management of adhesive capsulitis of the shoulder, although the optimal treatment has yet to be defined. PURPOSE: To conduct a network meta-analysis to compare the effects of different pharmacological interventions for adhesive capsulitis, administered either alone or after distension of the shoulder capsule. STUDY DESIGN: Network meta-analysis. METHODS: The authors searched Scopus, PubMed, and the Cochrane Central Register of Controlled Trials up to April 22, 2018, for completed studies. They enrolled trials that assessed the results of different pharmacological treatments for the primary management of adhesive capsulitis. The primary outcome was pain relief as measured by self-administered questionnaires. The secondary outcome included the assessment of composite instruments that evaluated, at a minimum, pain and function. The authors clinically interpreted the results after back-transforming the standardized mean differences into mean differences in simple instruments and assessed the quality of the source studies using the Cochrane "risk of bias" tool. RESULTS: The authors considered 30 trials with a total of 2010 participants in this systematic review. For pain relief, there was a significant difference in favor of intra-articular corticosteroids and distension of the shoulder capsule with steroids as compared with control in the short term (mean difference in visual analog scale (VAS): -1.4 [95% CI, -2.5 to -0.4] and -1.7 [95% CI, -3.2 to -0.1], respectively). Furthermore, rotator-interval injections were found to be superior to placebo (mean difference in VAS: -7.2; 95% CI, -10.1 to -4.4), although the intervention was considered in only 1 trial. Finally, there was a statistically significant difference in favor of multiple-site corticosteroid injections compared to placebo in both the short- (mean difference in Shoulder Pain and Disability Index [SPADI]: -86.7; 95% CI, -133.6 to -40) and intermediate-term assessment (mean difference in SPADI: -102.9; 95% CI, -163.9 to -41.8). CONCLUSION: Intra-articular corticosteroid intervention, administered either alone or after distension of the shoulder capsule, provided clinically meaningful improvements in the short term. Likewise, rotator-interval corticosteroid injections yielded promising results in terms of pain relief. However, these short-term benefits of steroids dissipated over time. Multiple-site corticosteroid injections showed clinical advantage over placebo for short- and intermediate-term composite outcome assessments.

Bladder training prior to urinary catheter removal in total joint arthroplasty. A randomized controlled trial.

BACKGROUND: Urinary catheters are commonly used in patients undergoing total hip and knee arthroplasty. Bladder training before catheter removal is reported to shorten the time to return to normal bladder function and reduce the incidence of urinary retention. OBJECTIVE: To evaluate the results of bladder training in patients with total hip and knee arthroplasty. DESIGN: Randomized controlled trial. SETTING: Orthopaedic Department of a tertiary Military Hospital. PARTICIPANTS: We enrolled consecutive patients undergoing total hip or knee arthroplasty during a period of 14 months. METHODS: We randomly allocated the participants into either a bladder training group, in which clamping was considered prior to catheter removal, or a free drainage removal group, using a computer-generated list and subsequently assessed their need for re-catheterization due to urinary retention. The primary outcome of this study was to evaluate if bladder training in patients with total hip and knee arthroplasty reduces the need for re-catheterization due to urinary retention. Multivariable logistic regression was used to model the association between postoperative urinary retention and independent variables (total hip or total knee arthroplasty, age, gender, and history of diabetes mellitus or prostatism). Secondary outcomes were the incidence of urinary tract infection, and subjective patients' symptoms. RESULTS: We included 218 patients in the study; 114 in the bladder training group and 104 in the free drainage removal group. All patients were over 50 years old with a mean age of 69.3 (SD = 8) years. We observed three cases of urinary retention in the bladder training and six in free drainage removal group, and the difference was not statistically significant (2.6% and 5.8% respectively, p = 0.316). We also observed increased odds of re-catheterization in patients with prostatism under medication (odds ratio was 26.42, p < 0.001). No infections or major subjective symptoms were noted. CONCLUSION: This trial shows that bladder training by catheter clamping offers no advantage over free draining removal of short-term urinary catheters in patients with total hip and knee arthroplasty. Therefore, we conclude that the bladder training procedure is not indicated. However, healthcare providers should monitor patients' urination after removal of the catheter.

Changes of Circulating MicroRNAs in Response to Treatment With Teriparatide or Denosumab in Postmenopausal Osteoporosis.

Context: Expression of microRNAs (miRs) related to bone metabolism in the serum may be affected by antiosteoporotic treatment. Objective: To investigate the effect of two antiosteoporotic agents with opposite effects on bone metabolism on miR expression profile in the serum. Design: Observational, open label, nonrandomized clinical trial. Setting: The outpatient clinics for Metabolic Bone Diseases of 424 General Military Hospital, Thessaloniki, Greece. Patients and Interventions: Postmenopausal women with low bone mass were treated with either teriparatide (TPTD; n = 30) or denosumab (n = 30) for 12 months. Main Outcome Measures: Changes in the serum expression of selected miRs linked to bone metabolism at 3 and 12 months of treatment. Secondary measurements: associations of measured miRs with changes in bone mineral density (BMD) at 12 months and the bone turnover markers (BTMs) C-terminal cross-linking telopeptide of type I collagen and procollagen type I N-terminal propeptide at 3 and 12 months. Results: We found significantly decreased relative expression of miR-33-3p at 3 months (P = 0.03) and of miR-133a at 12 months (P = 0.042) of TPTD treatment. BMD values at 12 months of TPTD treatment were significantly and inversely correlated with miR-124-3p expression at 3 months (P = 0.008). Relative expression of miR-24-3p and miR-27a was correlated with changes in BTMs during TPTD treatment and of miR-21-5p, miR-23a-3p, miR-26a-5p, miR-27a, miR-222-5p, and miR-335-5p with changes in BTMs during denosumab treatment. Conclusions: Circulating miRs are differentially affected by treatment with TPTD and denosumab. TPTD affects the relative expression of miRs related to the expression of RUNX-2 (miR-33) and DKK-1 gene (miR-133).

Epithelioid hemangioma of the scapula treated with chemoembolization and microwave ablation: Α case report.

Bone epithelioid hemangiomas are classified within benign vascular tumours but are commonly misdiagnosed as low-grade angiosarcomas or epithelioid hemangioendotheliomas. Current therapeutic interventions include various treatment options but local recurrence or distal lymph node involvement has been reported. We report a rare case of scapular epithelioid hemangioma that was initially treated using a combination of chemoembolization and microwave ablation. This combination has not been previously reported in the literature regarding the management of this tumour. A year after the first course of treatment, the tumour size has been reduced more than 70% and the patient has remarkable clinical improvement. Results reported in this case study demonstrated that combination of chemoembolization and microwave ablation is a feasible, safe and effective technique in the treatment of bone epithelioid hemangiomas. Even if the tumour is still present afterwards, a substantially smaller surgical excision will be needed.

Adhesive Capsulitis of the Shoulder. Is there Consensus Regarding the Treatment? A Comprehensive Review.

BACKGROUND: Adhesive capsulitis of the shoulder (ACS) is a common self-limiting condition characterized by disabling pain and restricted movements. Its pathophysiology is poorly understood, clinically it is characterized by stages of pain and stiffness, and finally often patients never recover fully. However, there is no consensus about available methods of treatment for ACS. The aims of this paper are to discuss and develop issues regarding approaches to management in ACS in the stages of it. METHODS: A review of the literature was performed and guidelines for the treatment of that clinical entity for doctors and health care professionals are provided. RESULTS: Anti-inflammatory medications, steroid and/or hyaluronate injections and physiotherapy is the mainstay of conservative management either alone in the first stages or in combination with other treatment modalities in the later stages. Next line of treatment, involving minor to moderate intervention, includes suprascapular nerve block, distension arthrography and manipulation under anaesthesia. In order to avoid complications of "blind intervention", arthroscopic capsular release is gradually more commonly applied, and in recalcitrant severe cases open release is a useful option. CONCLUSION: Various modalities of conservative management and gradually more surgical release are applied. However, often clinicians choose on personal experience and training rather than on published evidence.

Multifocal Epithelioid Hemangioendothelioma of the Foot and Ankle Developing a Postoperative Infection-Long-term Outcome: A Case Report.

A case of rare epithelioid hemangioendothelioma with multiple foot and ankle lytic lesions in a 41-year-old male is reported. The patient presented to our hospital after having received treatment elsewhere and developing a local postoperative infection. After thorough investigations and establishing the diagnosis, we initially treated the local infection and highlighted the potential risk of malignancy. Finally, respecting the patient's wishes, he was treated with consideration mostly of the pending foot and ankle fractures rather than the risk of malignancy. At 9.5 years postoperatively, the patient was clinically well and asymptomatic, without clinical, laboratory, or radiologic signs of malignancy, and the previous infection might have even played a remote role in that outcome. A review of the published data regarding the treatment of this unpredictable neoplasm is also presented.

Endoscopic Versus Open Excision of Os Trigonum for the Treatment of Posterior Ankle Impingement Syndrome in an Athletic Population: A Randomized Controlled Study With 5-Year Follow-up.

BACKGROUND: Open surgical excision of the os trigonum has been the traditional treatment for posterior ankle impingement syndrome (PAIS). However, the endoscopic excision has recently become quite popular. Purpose/Hypothesis: The purpose of our study was to compare the results of endoscopic versus open excision of a symptomatic os trigonum for the treatment of PAIS in an athletic population. It was hypothesized that the endoscopic technique would be superior to the open technique regarding functional outcomes, pain, and time to return to training and the previous sports level. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: From 2008 to 2011, 52 athletes underwent a symptomatic os trigonum excision; 26 athletes had an open procedure (group A) and 26 had an endoscopic procedure (group B). The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and the Visual Analog Score-Foot and Ankle (VAS-FA) were obtained, and the time to return to training and to previous sports level was recorded. RESULTS: Patients in group B appeared to have significant improvement of AOFAS hindfoot score compared with those in group A ( P < .05), whereas no statistical significance was found for the postoperative VAS-FA scores between the 2 groups. The mean ± SD time to return to training was 9.58 ± 3.98 weeks for group A and 4.58 ± 1.47 weeks for group B ( P < .001). The time to return to previous sports level was 11.54 ± 3.89 weeks for group A and 7.12 ± 2.25 weeks for group B ( P < .001). The overall complication rate was 23% for group A (6 cases) and 3.8% for group B (1 case). CONCLUSION: Both the open procedure and the endoscopic approach yielded acceptable outcomes in terms of function and pain. However, complication rates were remarkably lower with endoscopic treatment, and the time to return to full activities was much shorter. Endoscopic excision of the os trigonum is a safe and effective treatment option for athletes who require early return to their previous sports level.

The natural history of donor hamstrings unit after anterior cruciate ligament reconstruction: a prospective MRI scan assessment.

PURPOSE: The aim of this prospective study was to assess the natural history of the donor hamstrings, compared to the contralateral knee and thigh. METHODS: In 47 patients who had ACL reconstruction (hamstrings technique), bilateral knees and thighs were investigated using MRI scans, up to 2 years post-operatively. RESULTS: Tendon regeneration below the knee joint line of the semitendinosus occurred in 30/47 (64 %) patients and of the gracilis tendon in 17/47 (36 %) patients. Insertion of both tendons at the "pes anserinus", with normal anatomic relations, was observed in 5/47 (11 %) patients. Semitendinosus and gracilis donor muscles were found retracted in 41/47 (87 %) patients. In 25/47 (53 %) patients, there was evidence of fatty infiltration of the semitendinosus muscle. All (47/47) (100 %) patients showed semitendinosus muscle atrophy and 41/47 (87 %) patients showed gracilis muscle atrophy, compared to the contralateral limb. High signal intensity on STIR images was observed in the semitendinosus in 22/47 (46 %) patients and in the gracilis muscle in 30/47 (64 %) patients, on MRI examination performed up to 24 months post-operatively. CONCLUSIONS: The "regenerated" hamstrings tendons most commonly do not regenerate fully anatomically, so they should not be considered as a first choice for re-harvesting in revision ACL reconstruction. The "donor hamstrings muscles" are found to be shorter, contracted, thinner and with a long-term abnormal MRI signal, features which are considered to be related to reduced muscle performance (knee flexion and internal rotation) post-operatively. LEVEL OF EVIDENCE: II.

Treatment of Insertional Achilles Pathology With Dorsal Wedge Calcaneal Osteotomy in Athletes.

BACKGROUND: Insertional Achilles tendinopathy and retrocalcaneal bursitis is difficult to treat, and several operative techniques have been used after failure of conservative management. Dorsal wedge calcaneal osteotomy has been described for the treatment of insertional Achilles pathology. It was hypothesized that dorsal wedge calcaneal osteotomy would be an effective and safe method for the treatment of athletes with insertional Achilles pathology unrelieved by nonoperative measures. METHODS: Fifty-two athletes (64 feet) who had painful Achilles tendon syndrome unrelieved by 6 months of nonoperative measures were treated surgically. Dorsally based wedge calcaneal osteotomy was performed through a lateral approach, and 2 staples were used for fixation. Patients were scored pre- and postoperatively with the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot and Victorian Institute of Sports of Australia-Achilles (VISA-A) scores. RESULTS: At a minimum follow-up of 3 years, the patients' AOFAS and VISA-A scores improved from 59.5 ± 15.0 and 65.9 ± 11.1 preoperatively to 95.7 ± 6.2 and 90.2 ± 8.4 postoperatively, respectively. Clinical results were considered excellent in 38 patients, good in 12 patients, and fair in 2 patients. Return to previous sports activity time was 21 (SD, 8.0) weeks. One patient necessitated a revision operation. CONCLUSION: Operative treatment of insertional Achilles pathology in athletes with dorsal closing wedge calcaneal osteotomy was a safe and effective method that allowed for a quicker return to previous level of sports activities compared with other techniques. LEVEL OF EVIDENCE: Level IV, retrospective case series.
