Surgical treatment of high-grade acute intramuscular hamstring tendon injuries in athletes leads to predictable return to sports and no re-injuries.

PURPOSE: The purpose of this study was to assess the post-operative return to sport and re-injury rates following surgical repair of acute, first-time, high-grade intramuscular hamstring tendon injuries in high level athletes. METHODS: Patients were identified using the databases of two sports surgeons. Once patients were identified their clinical notes and imaging were reviewed to confirm that all patients had injuries to the intramuscular portion of the distal aspect of the proximal biceps femoris tendon. All imaging was reviewed by an experienced musculoskeletal radiologist to confirm diagnosis. Surgery for such injuries was indicated in high-level athletes presenting with acute hamstring injuries. All patients were operated on within 4 weeks. Outcomes included Tegner scores, return to sport, Lower Extremity Functional Score (LEFS), current hamstring symptoms and complications including re-injury. RESULTS: Eleven injuries (10 patients) were included in the study. All patients were male and Australian Rules Football players. Six patients were professional athletes and 4 semi-professional athletes. Median age was 24.5 (range 21-29) and median follow-up period was 33.7 months (range; 16-65). 91% were British Athletic Muscle Injury Classification (BAMIC) 3c and 9% were BAMIC 4c. 91% were classed as MR2 and 9% as MR3 on the simplified four-grade injury classification. Athletes achieved return to play (RTP) at an average of 3.1 months (SD 1.0) post repair. All but one patient achieved a Tegner score equal to pre-injury levels. Maximum LEFS was achieved by all patients. Minor pain scores (all with VAS < 1/10) on sciatic and functional stretch were recorded in 36% and 27% of patients respectively, with subtle neural symptoms (9%) and subjective tightness (36%) also noted. There were no surgical complications in our patient cohort. No patients had a re-injury or re-operation. CONCLUSIONS: Surgical repair of high-grade intramuscular tendon injuries of the biceps femoris hamstring muscle in athletes resulted in high levels of return to pre-injury sporting levels and no re-injuries. The intra-muscular tendon should be scrutinized when assessing hamstring injuries in elite sport and offer surgery in high-grade cases. LEVEL OF EVIDENCE: IV.

Combined quadriceps medial patellofemoral ligament reconstruction and osteochondral fixation offers good patient-reported outcomes and low rates of recurrent instability for osteochondral defects secondary to acute patella dislocation.

PURPOSE: Chondral injuries secondary to traumatic patella dislocation are common, and a subgroup of these are significant defects with fragments amenable to fixation. There is a paucity of published evidence assessing patients managed with combined acute patellofemoral stabilisation and osteochondral fixation. The purpose of this study is to report the outcomes of patients with osteochondral injuries secondary to acute traumatic patella dislocation treated with combined early fragment fixation and MPFL reconstruction using a quadriceps tendon turndown technique which has distinct advantages for this cohort, including preventing chondral overloading and non-violation of the patella bone. METHODS: Patients who underwent combined quadriceps tendon MPFL reconstruction and osteochondral fixation were included. Patient demographics, defect characteristics, complications and reoperations were evaluated. Patients were assessed with Lysholm, Kujala, KOOS-PF scores and satisfaction scale at follow up. Pre-operative MRI was assessed for presence of radiological risk factors for patella dislocation and post-operative MRI was used to assess cartilage quality with MOCART 2.0 score. RESULTS: A total of 19 patients (63.2% female) were included. The mean age was 17.4 ± 4.8 years and patients were followed up at a mean 15.8 ± 5.1 months post-surgery. The mean defect size was 2.4 cm2 ± 1.3 cm2, with the most common defect location being the patella (13/19; 68.4%) followed by the lateral femoral condyle (5/19; 26.3%). At final follow up, the overall mean Lysholm, Kujala, and KOOS-PF scores were 84.9 ± 11.1, 89.7 ± 5.8 and 80.6 ± 13.6, respectively. Seventeen patients (89.5%) were satisfied with their outcome. The mean MOCART 2.0 score at final follow-up was 72.5. One patient required medial capsular plication with removal of a loose chondral body and microfracture and 3 knees required minor reoperations. CONCLUSION: Combined acute osteochondral fragment fixation and MPFL reconstruction using a quadriceps tendon graft offers good radiological and patient-reported outcomes with high satisfaction and low rates of recurrent patella dislocation. To our knowledge, this is currently the largest series of its kind in the literature and the results of this study provide a rationale for a combined approach using a quadriceps tendon graft for this cohort.

The Effect of a Formal Nonoperative Management Program Combining a Hip Injection With Structured Adjunctive Exercise Rehabilitation in Patients With Symptomatic Femoroacetabular Impingement Syndrome.

BACKGROUND: Although the initial treatment recommendations for femoroacetabular impingement syndrome (FAIS) may include nonsurgical therapies such as injections and rehabilitation, many patients undergo isolated injections or a rudimentary exercise regimen. PURPOSE: To investigate the benefit of an intra-articular hip injection and concomitant structured exercise rehabilitation program in patients with symptomatic FAIS ≥6 months. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: For this study we recruited 49 patients with a mean age of 32.8 years (range, 16-56 years) and symptoms ≥6 months (range, 6-250 months) associated with FAIS, as confirmed via magnetic resonance imaging and radiography. After a guided intra-articular injection of corticosteroid and local anesthetic, patients underwent a structured 12-week rehabilitation program. Patients were assessed before and after injection (8 weeks and 4, 6, 12, and 24 months) with a range of patient-reported outcome measures (PROMs), including the 33-item International Hip Outcome Tool, Hip Outcome Score, modified Harris Hip Score, the Tegner Activity Score, a visual analog scale assessing the frequency and severity of hip pain, and a Global Rating of Change scale. Range of motion, peak isometric hip strength, and hop tests were assessed. Absolute scores and limb symmetry indices were calculated. The percentage of patients transitioning toward surgery over the period was evaluated. RESULTS: Of the 44 patients who underwent the injection and completed the initial 8-week rehabilitation component, 14 (31.8%) progressed toward surgical intervention over the 24-month postinjection period owing to dissatisfaction and/or symptom recurrence. Patients who progressed toward surgery, as compared with those who did not, reported significantly worse (P < .05) PROMs presurgery and more pain within the first 4 weeks after injection. In the nonoperative cohort, a significant improvement (P < .05) in all PROMs was observed, with 93% of these patients satisfied overall. The Global Rating of Change did not improve, although this was measured only after the injection, reflecting no further significant perceived global change from 8 weeks to 24 months. A significant increase (P < .05) in all hip range of motion and most isometric strength measures was observed at 8 weeks after injection, with these improvements largely sustained until 24 months. Bilateral improvements in hop capacity were observed, with hop test LSIs significantly improving for the single (p = 0.009), triple (p = 0.029) and triple crossover (p = 0.005) hop tests for distance. CONCLUSION: Although 32% of patients progressed toward surgery, significant improvement in hip pain, symptoms, and physical function was observed in the majority of patients with symptomatic FAIS as a result of a targeted nonoperative management pathway consisting of an intra-articular injection and a structured exercise program.

Journey-Deuce bicompartmental knee arthroplasty with the addition of computer navigation achieves good clinical outcomes and implant survival at 10 years.

PURPOSE: To report 10-year outcomes and survivorship in patients undergoing bicompartmental knee arthroplasty (BCKA) using the Journey-Deuce prosthesis in a consecutive prospective case series. METHODS: Between November 2006 and November 2009, 41 patients with a mean age of 69.6 years (range 51-86) underwent 51 bicompartmental knee arthroplasties with the Journey-Deuce knee prosthesis. All patients presented with symptomatic medial and patellofemoral compartment osteoarthritis, with intact cruciate ligaments and a preserved lateral compartment on plain radiographs and Magnetic Resonance Imaging. Clinical assessment was undertaken pre-surgery and at 1, 2, 5 and 10 years post-surgery using the Oxford Knee Score (OKS), EuroQol Group 5-Dimension self-reported questionnaire (EQ-5D) and maximal active range of motion (ROM). RESULTS: 30 patients (37 knees) were followed-up at a mean time of 11.4 years (SD 1.1; range 10.5-14.0). Eight patients (ten knees) were deceased and three could not be contacted at final review. No major component revision was performed. Pre-operative OKS 25.4 (SD 5.2; range 15-40), knee flexion 116.4° (SD 10.3°; range 100°-140°) and EQ-5D 70.5 (SD 19.9; range 25-95). 10-year OKS 43.5 (SD 4.1; range 32-48), knee flexion 127.3° (SD 11.1°; range 105°-144°) and EQ-5D 77.4 (SD 9.3; range 60-100). The OKS (p < 0.0001), EQ-5D (p = 0.024) and active knee flexion ROM (p < 0.0001) all significantly improved from pre-surgery to 1-year post-surgery, with no further significant changes in these scores between any post-operative time period up until 10 years. 32% (7/22) of tibial and 45% (10/22) of femoral components showed progressive radiolucencies between 2 and 5-year and 10-year follow-up. CONCLUSIONS: This is the largest cohort of patients having undergone BCKA (with the Journey-Deuce prosthesis) with longest follow-up described in the literature. At 10 years, patients presented with significantly improved clinical outcomes, comparable to other surgical arthroplasty options. No major component revision was performed. Progressive radiolucencies were noted in 32% of tibial and 45% of femoral components without corresponding clinical signs of loosening. LEVEL OF EVIDENCE: Level III.

Anterior Cruciate Ligament Reconstruction Using Autologous Hamstrings Augmented With the Ligament Augmentation and Reconstruction System Versus Hamstrings Alone: A Comparative Cohort Study.

BACKGROUND: Few studies have reported the return-to-sports (RTS) rate in patients after augmentation of autologous anterior cruciate ligament reconstruction (ACLR) with the Ligament Augmentation and Reconstruction System (LARS). PURPOSE/HYPOTHESIS: The purpose of this study was to compare postoperative outcomes in patients who underwent ACLR with single-bundle 4-strand hamstring autograft either without augmentation (HA-ACLR group) or with LARS augmentation (AUG-ACLR group). It was hypothesized that clinical outcomes and RTS rates would be better in the AUG-ACLR group at the 1-year follow-up, with similar outcomes in both cohorts by 2 years. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients who underwent ACLR between April 2014 and December 2017 were included in the current comparative study if they were skeletally mature and had 1- and 2-year follow-up outcomes; patients with concomitant meniscal surgery were also included. Included were 66 patients with AUG-ACLR (mean age, 26.8 years; 67% male) and 130 patients with HA-ACLR (mean age, 27.5 years; 61% male). Subjective outcome measures included the International Knee Documentation Committee Subjective Knee Evaluation Form, Knee injury and Osteoarthritis Outcome Score, Lysholm scale, Tegner activity scale, and the Noyes sports activity rating scale. Objective measures included knee laxity, maximal isokinetic knee flexion and extension strength, and the results of 4 functional hop tests. RESULTS: There were no significant differences between the study groups in age, sex distribution, body mass index, time to surgery, or number of concurrent meniscal surgeries. At the 1-year follow-up, the AUG-ACLR group had a significantly higher Tegner score (P = .001) and rates of RTS (P = .029) and return to preinjury level of sport (P = .003) compared with the HA-ACLR group. At the 2-year follow-up, there were no differences in these measures between groups. There were no between-group differences in other subjective outcomes, knee laxity, or strength and hop test results at either postoperative time point. There were also no differences in rerupture rates or other complications between the groups. CONCLUSION: Patients with AUG-ACLR had higher 1-year postoperative Tegner scores and rates of RTS and preoperative sport level compared with the HA-ACLR group. The 2-year rerupture rate for the AUG-ACLR group was low, and no intra-articular inflammatory complications were noted.

Is regional ankle block needed in conjunction with general anaesthesia for first ray surgery? A randomised controlled trial of ultrasound guided ankle block versus "blind" local infiltration.

BACKGROUND: Regional anaesthesia is commonly utilised for foot and ankle surgery. Debate remains at to the level of regional anaesthesia that is required. The objective of this study was to evaluate whether surgeon-delivered "blind" local anaesthetic infiltration around the first ray (metatarsal block without ultrasound guidance) was as effective as an ultrasound guided ankle block in providing post-operative analgesia after osseous first ray surgery performed under general anaesthetic. METHODS: 50 patients were recruited to a single surgeon and anaesthetist double-blinded randomised controlled trial at a single-centre. 20mls of 0.5% levobupivacaine was used to perform either an ankle or metatarsal nerve block. RESULTS: Forty-eight patients completed the study: 25 in the ankle block treatment arm and 23 in the metatarsal block arm. The demographics were comparable between groups. There was no statistical difference in visual analogue pain scores at two (21.3 vs 15.2), six (23.6 vs 20.8) and 24 (42.2 vs 50.4) hours following the procedure between the two groups (metatarsal block vs ankle block). Metatarsal block groups had a faster return of normal sensation (2.3 vs 2.8h) but there was no difference in time to safe mobilisation (2.6 vs 2.8h). CONCLUSION: This study demonstrates the efficacy and safety of surgeon delivered "blind" metatarsal block is comparable to an ultrasound guided ankle block for first ray surgery performed under general anaesthetic.

Non-surgical treatments for Morton's neuroma: A systematic review.

TITLE: Non-surgical treatment for Morton's neuroma: a systematic review. BACKGROUND: Morton's neuroma (MN) is an entrapment degenerative neuropathy with a strong predilection for the 3rd interdigital web space. The objective of our study was to identify the most significant evidence produced for the non-operative treatment of Morton's neuroma and assess outcomes of these interventions. METHOD: The electronic databases Medline, Ovid EMBASE, CINAHL and Cochrane CENTRAL from inception to October 2018 were searched. Two independent reviewers assessed the quality of the studies using the Modified Coleman Criteria. Statistics were combined across cohort studies to calculate pooled mean results, and improvements in outcomes. RESULTS: Initial electronic and hand search identified 486 studies. After title and abstract review there were 38 that went on to full-text review. Finally, 22 studies were included in the final review. We identified 9 different non-operative treatment modalities; Corticosteroid injection, Alcohol injection, Extra-corporeal Shockwave therapy (ESWT), Radiofrequency Ablation (RFA), Cryoablation, Capsaicin injection, Botulinum toxin, Orthosis and YAG Laser Therapy. Corticosteroid showed a statistically significant reduction in mean VAS over all their studies (p < 0.01), with 50% success at 12 months. Alcohol showed promising short-term pain-relieving results only. Orthotics, Capsaicin injections, Cryoablation, Botulinum toxin, RFA and ESWT did show statistically significant improvements, but with limitation to their application. CONCLUSION: Following review, the authors would recommend the use of corticosteroid injections to treat Morton's neuromas. The authors feel that radio-frequency ablation and cryoablation would benefit from further well designed randomised controlled trials.

Vitamin D and foot and ankle trauma: An individual or societal problem.

BACKGROUND: Vitamin D deficiency is a worldwide health concern. Hypovitaminosis D may adversely affect recovery from bone injury. The authors aimed to perform an audit of the Vitamin D status of patients in three centres in the United Kingdom presenting with foot and ankle osseous damage. METHODS: Serum 25-hydroxyvitamin-D (vitamin D) levels were obtained in patients presenting with imaging confirmed foot and ankle osseous trauma. Variables including age, gender, ethnicity, location, season, month, anatomical location and type of bone injury were recorded. RESULTS: 308 patients were included from three different centres. 66.6% were female. The average age was 47.7 (range; 10-85). The mean hydroxyvitamin-D levels were 52.0 nmol/L (SD 28.5). 18.8% were grossly deficient, 23.7% deficient, 34.7% insufficient and 22.7% within normal range. 351 separate bone injuries were identified of which 104 were categorised as stress reactions, 134 as stress fractures, 105 as fractures and 8 non-unions. Age, gender, anatomical location and fracture type did not statistically affect vitamin D levels. Ethnicity did affect Vitamin D levels: non-Caucasians mean levels were 32.4 nmols/L compared to Caucasian levels of 53.2 nmol/L (p=0.0026). CONCLUSION: Only 18.8% of our trauma patients had a normal Vitamin D level and 22.7% were grossly deficient. Patient age, gender, anatomical location and injury type did not statistically affect vitamin D levels. No difference between trauma and elective patients were found. Hypovitaminosis D is a problem of society in general rather than specific to certain foot and ankle injury patterns or particular patient groups sustaining trauma. LEVEL OF EVIDENCE: 2b.

Non-operative functional treatment for acute Achilles tendon ruptures: The Leicester Achilles Management Protocol (LAMP).

OBJECTIVES: The purpose of this study is to present outcomes and objective measures of assessment for acute Achilles tendon (AT) ruptures treated with an eight-week functional dynamic treatment protocol in a VACOped® boot with immediate full weight bearing mobilisation, the Leicester Achilles Management Protocol (LAMP). METHODS: A prospective study of all patients treated with the LAMP with minimum 12-month follow-up was performed. Patients completed the Achilles Tendon Rupture Score (ATRS) and in the latter part of the study, objective measures of the calf muscle girth and heel raise height were obtained. RESULTS: 442 patients were treated with the LAMP. There were nine (2%) re-ruptures in the 442 non-operative treated group of patients throughout the study period. ATRS at twelve months or more were available in 234 patients and objective measures in 77 patients. The mean age was 50 years. The mean ATRS was 75.5 at an average of 23 months post injury. Men had a statistically significant higher ATRS score when compared to women (p < 0.05). There was statistically significant difference in the calf muscle girth and the heel raise height when compared to the uninjured side at 12-months post-injury (p < 0.05). These differences did not correlate with the ATRS (p > 0.05). CONCLUSIONS: The LAMP is a simple yet effective regime for the non-operative treatment of acute AT ruptures, which can be universally adopted without the need for many resources. Compared to other studies, the overall time in the boot is less with low complication rates and similar patient reported outcomes.

Vitamin D levels in 577 consecutive elective foot & ankle surgery patients.

BACKGROUND: Vitamin D deficiency is a global concern impacting upon large communities and certain disease populations. It can adversely affect the outcome of orthopaedic operations. We aimed to perform an audit of the Vitamin D status of patients in two centres in the United Kingdom undergoing elective foot and ankle surgery. METHODS: Serum 25-hydroxyvitamin-D (vitamin D) levels were obtained prospectively in 577 consecutive elective patients undergoing elective foot and ankle surgery between October 2014 and March 2017 (29 months). Variables including age, gender, ethnicity, location, season, month and procedure type were recorded. RESULTS: 577 patients were included over the study period. 62.0% were female. Mean age was 53.2 (median 54.5, range 16.7-86.6). 300 patients were treated in Northampton and 277 in Leicester. The serum 25-hydroxyvitamin-D levels for the patient group were normally distributed. The mean was 52.3nmol/L (SD 28.0; range 7.5-175) and the median 47.5nmol/L. 21.7% were grossly deficient, 31.9% deficient, 28.9% insufficient and 17.5% within normal range. Age, gender and procedure type did not statistically affect vitamin D levels (p=0.5, t-test). Ethnicity, location and Winter season did affect Vitamin D levels (p<0.05). August was the most significant month with levels significantly higher than January, February, March, April, June, November and December (p<0.05, one-way ANOVA). CONCLUSIONS: Only 1 in 5.7 patients had a normal Vitamin D level and 1 in 4.6 were grossly deficient. Ethnicity and patient location significantly affected Vitamin D results. Summer months were noted to demonstrate significantly the highest levels and August the highest. We did not find that age or gender affected Vitamin D levels in our cohort.

Total Knee Arthroplasty for Osteoarthritis in Patients Less Than Fifty-Five Years of Age: A Systematic Review.

BACKGROUND: The proportion of younger patients undergoing total knee arthroplasty (TKA) is increasing and predictions state that the <55 age group will be the fastest growing group by 2030. We aim to collate data across studies to assess functional outcomes following TKA in patients <55 years of age using a systematic review. METHODS: The search identified 980 studies for title and abstract review. Forty-three full texts were then assessed. Thirteen studies underwent quality assessment and data extraction. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed throughout. Outcomes extracted included pre-operative and post-operative functional scores, range of motion, and patient satisfaction. Clinical complications and survival were also recorded. RESULTS: Across 13 studies we were able to demonstrate 54-point improvement in clinical Knee Society Score and a 46-point improvement on functional Knee Society Score. A 2.9° improvement in range of motion was found at final follow-up. Satisfaction rate was 85.5%. Cumulative percentage all-cause revision rate was 5.4% across 1283 TKAs at a mean 10.8 years of follow-up. Ten-year survival, for aseptic loosening alone, was 98.2%. CONCLUSION: TKA is an excellent treatment option for the young osteoarthritic knee with a >50% improvement in functional knee scores. Satisfaction is high and the revision rate remains 0.5% per year.

The hip fracture best practice tariff: early surgery and the implications for MRSA screening and antibiotic prophylaxis.

BACKGROUND: In April 2010, the Department of Health introduced the hip fracture best practice. Among the clinical criteria required to earn remuneration is surgery within 36 h of admission. However, early surgery may mean that methicillin-resistant Staphylococcus aureus (MRSA) colonisation status is not known before surgery, and therefore, appropriate antibiotic prophylaxis may not be administered. In view of this, our department's policy is to administer an additional dose of teicoplanin to patients with unknown MRSA status along with routine antimicrobial prophylaxis. AIM: The purpose of this study was to provide a safe and effective antimicrobial prophylaxis for hip fracture patients. METHODS: We prospectively collected details of demographics and antimicrobial prophylaxis for all patients admitted with a hip fracture in November 2011. This was repeated in February 2012 after an educational and advertising drive to improve compliance with departmental antimicrobial policy. Microbiology results were obtained from the hospital microbiology database. A cost-benefit analysis was undertaken to assess this regime. RESULTS: A total of 144 hip fracture patients were admitted during the 2 months. The average admission to surgery time was 32 h, and the average MRSA swab processing time was 35 h. 86 % of patients reached theatre with unknown MRSA status. Compliance with the departmental antimicrobial policy improved from 25 % in November 2011 to 76 % in February 2012. Potential savings of £ 40,000 were calculated. CONCLUSION: With best practice tariff resulting in 86 % of patients reaching theatre with unknown MRSA status, we advocate an additional single dose of teicoplanin to cover against possible MRSA colonisation.

Acromial stress fracture in a young wheelchair user with Charcot-Marie-Tooth disease: a case report.

: Acromial stress fractures are rare and have not been highlighted as a potential complication of wheelchair use. We report the case of a 22-year old female wheelchair bound patient with Charcot-Marie-Tooth disease who presented with a four-year history of shoulder pain which impaired mobility and quality of life. Plain radiographs showed a cortical irregularity of the acromion but no double-density sign. After CT scans a non-united acromial stress fracture was diagnosed. She had no other shoulder pathology. The new technique of using a superiorly closing wedge osteotomy with cancellous lag screw fixation was successful in correcting the mobile non-united acromial fragment and resolving her pain.
