Management of Patellar Tendinopathy.

Patellar tendinopathy is a common pathology typically seen in athletes involved in repetitive explosive jumping and running activities. Also known as jumpers' knee, it is commonly seen in high-level basketball players. Typically, athletes continue to play with symptoms, which can be aggravated and progress to partial patellar tendon tears. When partial patellar tendon tears occur, prolonged recovery and decreased performance is commonly seen. The pathology and treatment can be frustrating for both the athlete and medical provider. Patellar tendinopathy typically does not involve inflammation but rather microinjury to the tendon fibers, which leads to mucoid degeneration, necrosis, and loss of transitional fibrocartilage. When partial tendon tears do occur, the typical location is posteromedially adjacent to the patella. Treatment involves a stepwise approach starting with nonoperative means, including activity modification, nonsteroidal anti-inflammatories, and physical therapy focused on eccentrics. Extracorporeal shock wave treatments and injections with platelet-rich plasma or bone marrow aspirate concentrate should be considered, with evolving literature to support their use. Ultrasound percutaneous tendon scrapping with a needle supplemented with the aforementioned injections is an emerging treatment option that the authors have found to be helpful, although further studies are required. Surgical intervention is considered after failure of nonoperative treatments, and typically occurs in tears greater than 50% of the tendon thickness and in tendons with increased thickness (>8.8 mm). Open or arthroscopic debridement can be considered, with no studies showing superior outcomes with either technique; however, no high-quality comparison studies exist. The authors prefer an open technique where, much like a bone-patellar tendon-bone harvest, the unhealthy proximal tendon and bone are excised with then closure of the healthy tendon with absorbable sutures. Suture anchor repair may also be used when necessary. In a recent systematic review, surgical management of patellar tendinopathy has been shown to result in improved patient-reported outcomes with return to sport at high levels.1 Treatment for the difficult and sometimes frustrating pathology of patellar tendinopathy continues to evolve, with biologic and less-invasive ultrasound-based treatments showing promise, and surgical intervention providing reliable outcomes.

Satisfactory mid-term clinical outcomes of endoscopic tenotomy for iliopsoas tendinopathy following total hip arthroplasty.

PURPOSE: To report 5-year outcomes of endoscopic iliopsoas tenotomy in patients with iliopsoas tendinopathy following total hip arthroplasty (THA) and determine whether clinical scores are associated with cup position. METHODS: Patients who underwent endoscopic iliopsoas tenotomy for iliopsoas tendinopathy following THA (2014-2017) were contacted. Indications for endoscopic iliopsoas tenotomy after THA were groin pain during active hip flexion, exclusion of other causes of groin pain, and no pain relief after 6 months of conservative treatment. Pretenotomy cup inclination and anteversion were measured on radiographs; axial and sagittal cup overhang were measured on computed tomography (CT) scans. Oxford hip score (OHS), modified Harris hip score (mHHS), and groin pain were assessed. RESULTS: The initial cohort comprised 16 men (17 hips) and 31 women (32 hips), aged 60.7 ± 10.6 years. Cup inclination and anteversion were, respectively, 46.2 ± 6.2° and 14.6 ± 8.4°, while axial and sagittal cup overhang were, respectively, 4.4 ± 4.0 mm and 6.9 ± 4.5 mm. At ≥5 years follow-up, four hips underwent cup and stem revision, two underwent isolated cup revision and one underwent secondary iliopsoas tenotomy. OHS improved by 23 ± 10 and mHHS improved by 31 ± 16. Posttenotomy groin pain was slight in 20.0%, mild in 17.5% and moderate in 12.5%. Regression analyses revealed that net change in mHHS decreased with sagittal cup overhang (ß = -3.1; 95% confidence interval [CI] = -4.6 to -1.7; p < 0.001), but that there were no associations between cup position and net change in OHS. CONCLUSIONS: Endoscopic iliopsoas tenotomy provides good mid-term clinical outcomes in patients with iliopsoas tendinopathy following THA. Furthermore, improvements in mHHS were found to decrease with increasing sagittal cup overhang, in cases for which adequate preoperative imaging was available. LEVEL OF EVIDENCE: Level IV.

Shear wave elastography correlates to degeneration and stiffness of the long head of the biceps tendon in patients undergoing tenodesis with arthroscopic shoulder surgery.

BACKGROUND: Tendinopathy of the long head of the biceps (LHB) tendon causes degeneration and changes its stiffness. However, a reliable means of diagnosis has not been established. Shear wave elastography (SWE) provides quantitative tissue elasticity measurements. In this study, the relationship of preoperative SWE values with biomechanically measured stiffness and degeneration of the LHB tendon tissue was investigated. METHODS: LHB tendons were obtained from 18 patients who underwent arthroscopic tenodesis. SWE values were measured preoperatively at 2 sites, proximal to and within the bicipital groove of the LHB tendon. The LHB tendons were detached immediately proximal to the fixed sites and at their superior labrum insertion. Tissue degeneration was histologically quantified using the modified Bonar score. Tendon stiffness was determined using a tensile testing machine. RESULTS: The SWE values of the LHB tendon were 502.1 ± 113.6 kPa proximal to the groove and 439.4 ± 123.3 kPa within the groove. The stiffness was 39.3 ± 19.2 N/mm. The SWE values displayed a moderate positive correlation with the stiffness proximal to the groove (r = 0.80) and within it (r = 0.72). The SWE value of the LHB tendon within the groove showed a moderate negative correlation with the modified Bonar score (r = -0.74). CONCLUSIONS: These findings suggest that preoperative SWE values of the LHB tendon correlate moderately positively with stiffness and moderately negatively with tissue degeneration. Therefore, SWE may predict LHB tendon tissue degeneration and changes in stiffness caused by tendinopathy.

Gluteal Tendinopathy Is Associated With Lower Patient-Reported Outcome Measures in Total Hip Arthroplasty With a Posterior Approach: A Prospective Cohort Study of 1,538 Patients.

BACKGROUND: Gluteal tendinopathy (GT) is found in 20 to 25% of patients undergoing total hip arthroplasty (THA). Despite this, there is a scarcity of literature assessing the association between GT and THA outcomes. The aim of this study was to evaluate whether intraoperative diagnosis of GT negatively affected postoperative outcomes. METHODS: Consecutive patients undergoing primary THA for osteoarthritis via a posterior approach over 5 years were recruited in a prospective study. Gluteal tendinopathy was assessed and graded at the time of surgery, but not repaired. A total of 1,538 (93%) completed the patient-reported outcome measures (PROMs) at 1 year after surgery and were included in the analysis. The PROMs included the Oxford Hip Score (OHS), Hip Disability and Osteoarthritis Outcome Score Joint Replacement (HOOS JR), and EuroQol 5-Dimension, and were collected preoperatively and one year after THA. RESULTS: The gluteal tendons were graded as 4 distinct grades: normal (n = 1,023, 66%), tendinopathy but no tear (n = 337, 22%), partial thickness tear (n = 131, 9%), and full thickness tear (n = 47, 3%). The occurrence of GT was associated with age, body mass index, and sex. There was no significant difference in baseline OHS or HOOS JR scores according to GT grade. As GT grade increased, lower median 1-year OHS (P = .001) and HOOS JR (P = .016) were observed. This association was confirmed by linear regression analysis with 1-year OHS (B = 0.5, 95% CI = -0.9 to -0.1, P = .011) when controlled for age and sex. CONCLUSIONS: Gluteal tendinopathy was commonly observed and was associated with inferior 1-year PROMs in patients undergoing THA via posterior approach. Increasing degree of tendinopathy was a negative prognostic factor for outcomes and patient satisfaction. LEVEL OF EVIDENCE: Level 2 (High quality prospective cohort study).

The surgical learning curve for percutaneous Zadek osteotomy for treatment of insertional achilles tendinopathy.

INTRODUCTION: The Zadek Osteotomy has been described as an effective technique for the treatment of insertional Achilles tendinopathy. Recently, this strategy has been modified using minimally invasive techniques. A learning curve has been observed in many minimally invasive procedures in foot and ankle surgery. This retrospective study first intended to evaluate if there is a learning curve associated with the percutaneous Zadek Osteotomy. Further, if a learning curve was observed, we planned to assess the data for associated changes in complications and postoperative outcomes. METHODS: A retrospective analysis of 98 patients who underwent percutaneous Zadek Osteotomy was performed. Patient charts were reviewed for operative times, complications, union rates, and Foot Function Index (FFI) and Visual Analogue Scale (VAS) scores. Analysis of variance was utilized to assess for differences between groups of cases. RESULTS: Patients included 61 females and 37 males. Mean age was 51.28 ± 11.12 (range 28-81) years. Mean follow-up time was 42.07 ± 12.99 (range 24-65) months. Significant increases in operative times were observed in cases 1-14 when compared to cases 15-98 (p < 0.001). Improvements in FFI and VAS scores were observed at final follow-up within each case group (p < 0.001); there were no differences detected in FFI or VAS scores between groups of cases. There was no difference detected in number of complications between intervals of cases. CONCLUSION: A learning curve was observed for the percutaneous Zadek Osteotomy, which was overcome around case 14. This learning curve was only observed in terms of procedure length. A surgeon's level of inexperience with the technique does not appear to affect functional outcomes, nonunion, or need for revision. LEVEL OF EVIDENCE IV: Data will not be deposited in a repository.

Impact of BMI on the Surgical Management of Chronic Insertional Achilles Tendinopathy.

Posterior heel pain secondary to insertional Achilles tendinopathy is a common condition that often times requires surgical management. Typically, this involves reflecting a portion of the Achilles tendon from its insertion to adequately debride devitalized or thickened tendon as well as any osseous prominence and then reattached into the calcaneus via suture anchors. Oftentimes, it is suggested that patients with an increased body mass index (BMI) have a higher risk of complications. However, there is no published evidence to support this claim. The present study is a retrospective review of 78 patients who underwent detachment/reattachment of the Achilles tendon for chronic insertional Achilles tendinopathy. Patients were separated into three groups based on BMI: normal, obese, and morbidly obese. The mean BMI of all patients included was 35.6 kg/m2 (range: 21.8-54.9, SD: 6.9). We compared complication rates between the groups and found no significant difference (p = .541). Patients in all groups also demonstrated statistically significant improvements in both American Orthopedic Foot and Ankle Society (AOFAS) hindfoot-ankle scores (Normal BMI: p = .002; Obese: p = <.001; Morbidly obese: p = <.001) and Patient-Recorded Outcomes Measurement Information System (PROMIS) scores (Normal BMI: p = .003; Obese: p = <.001; Morbidly obese: p = .001). In conclusion, the results of our study demonstrate that detachment/reattachment of the Achilles insertion in the management of insertional Achilles tendinopathy in obese and morbidly obese patients may be safe and effective without the risk of increased complications.

Ultrasound- and Doppler-Guided WALANT Arthroscopic Surgery for Patellar Tendinopathy with Partial Rupture in Elite Athletes-A 2-Year Follow-Up of a Prospective Case Series.

Background and Objectives: Patellar tendinopathy is difficult to treat, and when combined with partial rupture, there are additional challenges. The aim of this study was to evaluate the subjective outcome and return-to-sport status after ultrasound (US)- and colour doppler (CD)-guided wide awake local anaesthetic no tourniquet (WALANT) arthroscopic shaving in elite athletes. Material and Methods: Thirty Swedish and international elite athletes (27 males) with a long duration (>1 year) of persistent painful patellar tendinopathy in 35 patellar tendons, not responding to non-surgical treatment, were included. All patients were treated with the same protocol of arthroscopic shaving, including bone removal and debridement of partial rupture, followed by at least 3 months of structured rehabilitation. The VISA-P score and a study-specific questionnaire evaluating physical activity level and subjective satisfaction with the treatment were used for evaluation. Results: At the 2-year follow-up (mean 23, range 8-38 months), 25/30 patients (29/35 tendons) were satisfied with the treatment result and had returned to their pre-injury sport. The mean VISA-P score increased from 37 (range 7-69) before surgery to 80 (range 44-100) after surgery (p < 0.05). There was one drop-out (one tendon). There were no complications. Conclusions: US- and CD-guided WALANT arthroscopic shaving for persistent painful patellar tendinopathy, including bone removal and debridement of partial rupture, followed by structured rehabilitation showed good clinical results in the majority of the elite-level athletes.

Dorsal calcaneal wedge removal in zadek osteotomy: A cadaveric study.

BACKGROUND: Insertional Achilles tendinopathy (IAT) is a common pathology with multiple surgical interventions available for treatment. The Zadek, dorsal closing wedge calcaneal osteotomy (ZO) has been demonstrated to be effective treatment of IAT. There have been various recommendations in the literature as to what measurement of wedge removal should be considered ideal to produce greatest postoperative range of motion (ROM), thus postoperative biomechanical potential. Accordingly, the purpose of this cadaveric study was to assess the range of motion achieved after various measurements of wedge removal by ZO. METHODS: The ZO was performed on six cadaveric specimens. A 7.5 mm and 15 mm wedge osteotomy was marked and sequentially completed on each specimen. Lateral fluoroscopic imaging was utilized to take preoperative and postoperative ROM measurements for each osteotomy. Dorsiflexion (DF) and plantarflexion (PF) ROM arcs were measured for each wedge size and compared by t-test. Effect sizes were calculated by Cohen's d analysis. RESULTS: Maximal DF was 110.87 ± 12.97 deg in the pre-osteotomy state. Removal of a 7.5 mm wedge improved DF by 8 deg to a mean 102.93 ± 13.81 deg (p = 0.08). Removal of a 15 mm wedge improved DF by 16 deg to a mean 95.96 ± 11.41 deg (p = 0.003). Cohen's d and effect size calculation demonstrated a 7.5 mm wedge to have a small effect on DF, while a 15 mm wedge had a medium effect (0.29, 0.52 respectively). Maximal PF did not change significantly amongst the pre-osteotomy, 7.5 mm wedge, or 15 mm wedge positions. ICC was 0.96. CONCLUSION: Based on the results presented in this study, removal of a 15 mm wedge with ZO yields significant and greater improvement in ROM than a 7.5 mm wedge. We hope the current study will better inform preoperative planning for ZO. STUDY TYPE: Prospective Cadaver Study. LEVEL OF EVIDENCE: V.

Haglund resection versus Haglund non-resection for calcific insertional Achilles tendinopathy with Haglund deformity: A retrospective study.

BACKGROUND: Calcific insertional Achilles tendinopathy(CIAT) with Haglund deformity is a type of recalcitrant tendinopathy. The necessity of concomitant removal of Haglund deformity during CIAT treatment is controversial. The present study aimed to evaluate the functional outcomes between Haglund resection and Haglund non-resection in the treatment of CIAT with Haglund deformity. METHODS: A retrospective study included 29 patients who were underwent Achilles tendon debridement, bursal excision, and subsequent tendon reattachment.for CIAT with Haglund deformity. All patients were divided into 2 groups according to Haglund resection (resection group, n = 16) and Haglund non-resection (non-resection group, n = 13) using the parallel line method on lateral calcaneal X ray after surgery. Patients were evaluated in terms of the American Orthopedic Foot and Ankle Society (AOFAS), Visual Analog Scale (VAS) and Victorian Institute of Sports Assessment-Achilles (VISA-A) scores and the mean time of activities of daily living (ADL). Anatomy changes included the Fowler-Philip angle, calcaneal pitch angle and Achilles tendon force arm were measured with radiography preoperatively and postoperatively. RESULTS: Both groups exhibited a significant increase in AOFAS, VAS and VISA-A scores after surgery. There were no significant differences between the resection group and the non-resection group for the AOFAS (92.38 ± 5.7 vs. 93.15 ± 12.17; P = 0.82), VAS (0.5 ± 0.52 vs. 0.61 ± 0.87; P = 0.66) and VISA-A questionnaire (82.56 ± 13.46 vs. 74.92 ± 16.4; P = 0.18) at the latest follow-up. The mean time of ADL in the non-resection group was significantly faster compared to that of the resection group (8.15 ± 2.51 weeks vs. 11.31 ± 4.06 weeks, P = 0.02). The Fowler-Philip angle of the resection group decreased from 55.55° ± 12.34° preoperatively to 44.52° ± 10.24° at the latest follow-up (P = 0.001). The Fowler-Philip angle of the non-resection group decreased from 54.38° ± 8.41° preoperatively to 46.52° ± 8.02° at the latest follow-up (P = 0.016). The calcaneal pitch angle of the resection group increased from 22.76° ± 5.37° preoperatively to 25.98° ± 6. 4° at the latest follow-up (P = 0.018). The Achilles tendon force arm of the resection group decreased from 178.50 mm ± 5.37 mm preoperatively to 173.90 mm ± 8.07 mm at the latest follow-up (P = 0.018). CONCLUSION: Resection or non-resection of the posterosuperior calcaneal tuberosity for CIAT with Haglund deformity would both provide satisfactory functional outcomes. Haglund non-resection may expedite patients' return to their daily activities, suggesting a Haglund deformity resection may be unnecessary in the surgical treatment for CIAT with Haglund deformity.

Double-Row Achilles Insertional Repair With Rip-Stop Increases Construct Strength Compared to Traditional Techniques: A Biomechanical Study.

BACKGROUND: Although double-row suture-anchored (DRSA) techniques for Achilles insertional tendinosis has proven successful, a reoccurring failure mode not yet addressed is suture tearing through the tendon. This study aims to address suture tearing by incorporating a rip-stop element. Authors hypothesized that the Rip-Stop group would demonstrate increased strength compared with more traditional techniques. METHODS: 12 paired cadaveric feet were used in this study (n = 24). One sample from each pair was assigned to receive the standard double-row (SDR) Achilles repair with 4.75-mm knotless anchors (n = 12). The control's matched sides were divided between 2 DRSA bridge groups: modified double-row (MDR) bridge with 3.9-mm anchors or rip-stop double-row (RS-DR) bridge repair with soft proximal anchors and 3.9-mm anchored distal row. In neutral position, specimens underwent 1000 cycles (20-100 N) followed by load to failure. Displacements, stiffness, ultimate load, and failure mode were recorded. RESULTS: RS-DR had the lowest initial displacement values followed by SDR and MDR (1.3 ± 0.4, 2.7 ± 1.4, and 3.2 ± 1.3 mm, respectively). Significance was detected when comparing initial displacement of RS-DR to MDR (P = .038). Cyclic displacement was lowest for RS-DR, followed by MDR and SDR (1.6 ± 0.9, 2.2 ± 1.1, and 4.5 ± 3.2 mm, respectively). Cyclic stiffness was similar for RS-DR and MDR (89.1 ± 24.6 and 81.9 ± 5.6 N/mm, respectively). RS-DR ultimate load (1116.8 ± 405.7 N) was statistically greater than SDR (465.6 ± 352.7, P = .003). CONCLUSION: RS-DR-repaired specimens demonstrated a decrease in displacement values and increased ultimate load and stiffness when compared to other groups. Results of this cadaveric model suggest that the addition of a rip-stop to DRSA Achilles repair is more impactful than anchor size. Limitations include that this was a time-zero biomechanical study, which cannot simulate the performance of the repairs during postoperative healing and recovery. CLINICAL RELEVANCE: A rip-stop technique for Achilles repair effectively improves dynamic mechanical characteristics and may mitigate suture tearing through tendon in a patient cohort.

Needle­based gastrocnemius lengthening: a novel ultrasound­guided noninvasive technique: part II-clinical results.

BACKGROUND: Isolated gastrocnemius contracture has been associated with more than 30 lower limb disorders, including plantar heel pain/plantar fasciitis, Achilles tendinosis, equinus foot, adult flatfoot, and metatarsalgia. Although many techniques are available for gastrocnemius recession, potential anesthetic, cosmetic, and wound-related complications can lead to patient dissatisfaction. Open and endoscopic recession techniques usually require epidural or general anesthesia, exsanguination of the lower extremities and stitches and can damage the sural nerve, which is not under the complete control of the surgeon at all stages of the procedure. The purpose of this study is to evaluate the clinical results of a surgical technique for gastrocnemius lengthening with a needle, as previously described in cadaver specimens. METHODS AND RESULTS: We performed a prospective study of ultrasound-guided gastrocnemius tendon lengthening in level II using a needle in 24 cases (19 patients) of gastrocnemius contracture. The study population comprised 12 males and 7 females. Mean age was 41 years (18-64). All but 5 recessions were bilateral and occurred simultaneously. The indication for the procedure was gastrocnemius contracture; although the patients also presented other conditions such as non-insertional Achilles tendinopathy in 6 patients (2 were bilateral), insertional Achilles calcifying enthesitis in 4 (1 was bilateral), metatarsalgia in 4, flexible flat foot in 1 and plantar fasciitis in 5 (2 were bilateral). The inclusion criteria were the failure of a previous conservative protocol, that the Silfverskiöld test was positive, and that the pathology suffered by the patient was within the indications for surgical lengthening of the patients and were described in the scientific literature. The exclusion criteria were that the inclusion criteria were not met, and patients with surgical risk ASA 3 or more and children. In these patients, although possible, it is preferable to perform the procedure in the operating room with monitoring, as well as in children since they could be agitated during the procedure at the office. We used the beveled tip of an Abbocath needle as a surgical scalpel. All patients underwent recession of the gastrocnemius tendon, as in an incomplete Strayer release. We evaluated pre- and postoperative dorsiflexion, outcomes, and procedural pain (based on a visual analog scale and the American Orthopedic Foot and Ankle Society scores), as well as potential complications. No damage was done to the sural bundle. RESULTS: Ankle dorsiflexion increased on average by 17.89°. The average postoperative visual analog score for pain before surgery was 5.78, 5.53 in the first week, 1.89 at 1 month, and 0.26 at 3 months, decreasing to 0.11 at 9 months. The mean postoperative American Orthopedic Foot and Ankle Society Ankle-Hindfoot score the average was 50.52 before surgery, 43.42 at 1 week, 72.37 at 1 month, 87.37 at 3 months, and 90.79 at 9 months. CONCLUSION: Ultrasound-guided needle lengthening of the gastrocnemius tendon is a novel, safe, and effective technique that enables the surgeon to check all the structures clearly, thus minimizing the risk of neurovascular damage. The results are encouraging, and the advantages of this approach include absence of a wound and no need for stitches. Recovery is fast and relatively painless. A specific advantage of ultrasound-guided needle lengthening of the gastrocnemius tendon is the fact that it can be performed in a specialist's office, with a very basic instrument set and local anesthesia, thus reducing expenses.

Strength and Functional Outcomes Following Achilles Tendon Reconstruction With Hamstring Tendon Autograft Augmentation.

BACKGROUND: The proposed advantages of hamstring autograft reconstruction when compared to alternative procedures, such as flexor hallucis longus (FHL) transfer, V-Y lengthening, and allograft reconstruction, are improved healing and reproduction of normal tendon biomechanics and reduced morbidity within the foot and ankle. In this study, we examined the effect of Achilles tendon reconstruction using hamstring autografts on strength and functional outcomes. METHODS: Patients who underwent Achilles repair with a hamstring autograft for insertional or midsubstance tendinopathy, delayed diagnosis of rupture, or infection after primary repair were evaluated for inclusion. Forty-six patients were identified; 12 further augmented with an FHL transfer are included in the analysis. Isokinetic testing was completed with a Biodex dynamometer under supervision of a physical therapist masked to surgical side. Pre- and postoperative Foot and Ankle Outcome Scores (FAOS, before March 2016) or Patient-Reported Outcomes Measurement Information System (PROMIS, after March 2016) surveys were collected. RESULTS: For knee flexion, peak torque was not significantly different when comparing operative and nonoperative sides at 180 degrees/second (45.38 Nm vs 45.96 Nm; P = .69) nor at 300 degrees/second (44.2 Nm vs 47.02 Nm; P = .069). Knee extension absolute peak torque was only found to be significantly weaker on the operative side at the faster testing (75.5 Nm vs 79.56 Nm; P < .05). Peak ankle plantarflexion torque was significantly weaker on the operative side at both the slower speed (60 degrees/second: 39.9 Nm vs 48.76 Nm; P < .005) and the faster speed (120 degrees/second: 31.3 Nm vs 40.7 Nm; P < .001). Average power for ankle plantarflexion did not differ significantly from the operative side to the nonoperative side in the slower test (26.46 W vs 27.48 W; P = .60) but did significantly differ on the faster test (32.13 W vs 37.63 W; P = .041). At an average of 19.9 months postoperation, all physical function and pain-related patient-reported outcome scores showed clinically and statistically significant improvement. CONCLUSION: Achilles reconstruction with a hamstring autograft ± FHL transfer allowed patients with severe Achilles pathology to return to good subjective function, with modest deficits in calf strength compared with the uninjured side. Overall knee flexion strength did not appear impaired. These results suggest that hamstring autograft reconstruction is a viable method to treat these complex cases involving a lack of healthy tissue, allowing patients to return to symptom-free physical function and athletic activity. LEVEL OF EVIDENCE: Level IV, case series.

[Comparison of the efficacy of phlebotomy under touch pain point and ultrasound-guided puncture decompression in the treatment of acute calcific supraspinatus tendinitis].

OBJECTIVE: To compare the efficacy of blood letting under pain point touch and ultrasound-guided puncture decompression in the treatment of acute supraspinatus muscle calcifying tendinitis. METHODS: From January 2020 to January 2023, 45 patients with acute supraspinatus muscle calcifying tendinitis were selected and divided into treatment group and control group. In the treatment group, a total of 22 patients were treated with ultrasound-guided puncture decompression, including 16 females and 6 males, aged from 20 to 64 years old(39.31±5.80) years old, 11 on the left shoulder and 11 on the right shoulder. In the control group, there were 23 cases, including 15 females and 8 males, aged from 19 to 66 years old (40.67±6.13) years old, 12 on the left shoulder and 13 on the right shoulder. The treatment was treated with pain point touch bloodletting therapy. The visual analog scale (VAS) pain score, University of California, Los Angeles(UCLA) shoulder system score and shoulder Constant-Murley score were used to evaluate the therapeutic effect before treatment, 1 weeks, 1 month and 3 months after treatment, respectively. RESULTS: One patient in the control group gave up follow-up for personal reasons after 1 week of treatment, and the other 44 patients completed all follow-up. Six months after treatment, there were no recurrence cases in both groups. After statistical analysis, VAS pain score, UCLA score and Constant-Murley score of the treatment group and the control group were significantly different from those before treatment (P<0.05), and the improvement was more obvious in the treatment group. There was no statistical significance between the two groups (P>0.05). CONCLUSION: Bloodletting under pain point touch and ultrasound-guided puncture decompression are effective in the treatment of acute calcific supraspinatus tendinitis, with simple operation and low cost, which can effectively reduce local pain and effectively improve shoulder joint function. Primary hospitals can selectively operate treatment according to their own conditions.

Navicular bone fracture and severe deep digital flexor tendinopathy after palmar digital neurectomy in two horses.

Background: Navicular syndrome is a common cause of forelimb lameness in horses. Beyond changes to the navicular bone itself, horses with a clinical diagnosis of navicular syndrome often have pathology associated with other components of the navicular apparatus, including the navicular bursa, deep digital flexor (DDF) tendon, collateral sesamoidean ligaments, and impar ligament. Palmar digital neurectomy (PDN) is often used as a salvage procedure for horses diagnosed with navicular syndrome that become unresponsive to medical management. There are many potential complications associated with PDN, some of which are debilitating. Case Description: This report describes two cases of navicular bone fracture with severe DDF tendinopathy and distal interphalangeal joint subluxation/hyperextension that occurred 12 and 19 weeks after bilateral forelimb PDN. Conclusion: These two cases highlight the importance of proper patient selection before PDN due to the high incidence of undiagnosed soft tissue pathology in conjunction with radiographic evidence of navicular syndrome. Advanced imaging of the digit is recommended to identify and characterize any soft tissue pathology associated with the navicular apparatus before pursuing PDN to avoid disease progression and catastrophic injury.

Xantoma del tendón de aquiles bilateral: debut de xantomatosis cerebrotendinosa / Bilateral achilles tendon xanthoma: cerebrotendinous xanthomatosis debut

OBJETIVO Presentación de un inusual caso de xantomatosis cerebrotendinosa en un paciente de edad cuya primera manifestación fueron xantomas bilaterales del tendón de Aquiles. MATERIAL Y MÉTODOS Mujer de 62 años, que presenta tumoraciones, que presenta tumoraciones sólidas y polilobuladas, en la cara posterior de ambos tendones de Aquiles de 8 años de evolución. El diagnóstico se realizó mediante el hallazgo de hiperlipidemia y estudio genético. Se realió la exóresis quirúrgica parcial de las tumoraciones. RESULTADOS A los 5 años de la cirugía del pie izquierdo y 4 años del pie derecho la paciente estaba asintomática. Presentaba una fuerza para la flexión plantar bilateral de 5/5, pudiendo caminar y subir escaleras sin molestias. Presentaba una escala AOFAS de 85 y 90 puntos en el pie izquierdo y derecho, respectivamente. No hubo recidivas. DISCUSIÓN Los xantomas son depósitos de colesterol en el tejido conectivo de la piel, tendones o fascia, como resultado de una hiperlipoproteinemia. La importancia del caso radica en su sospecha diagnóstica, ya que la xantomatosis cerebrotendinosa suele manifestarse en pacientes de menos de 30 años de edad y en los que se ha recomendado la resección radical de las tumoraciones, e incluso del tendón, debido a las frecuentes recidivas. CONCLUSIÓN En pacientes de mayor edad con lesiones que infiltran el tendón, se puede optar por un tratamiento menos agresivo con un buen resultado clínico.

OBJETIVE Presentation of an unusual case of cerebrotendinous xanthomatosis in an elderly patient whose first manifestation was bilateral Achilles tendon xanthomas. MATERIAL AND METHODS 62-year-old woman presenting solid and polylobed tumors on the posterior aspect of both Achilles tendons for eight years. The diagnosis was made by means of hyperlipidemia and a genetic study. Surgical partial excision of the tumors was performed. RESULTS Five years after surgery on the left foot and four years after the right foot, the patient was asymptomatic. Bilateral plantar flexion force was 5/5, The patient was able to walk and climb stairs without discomfort. AOFAS score was 85 and 90 on the left and right feet, respectively. There were no recurrences. DISCUSSION Xanthomatosis is a genetic alteration with deposits of cholesterol in connective tissue of the skin, tendons or fascia, because of hyperlipoproteinemia. The importance of the present case lies in its diagnostic suspicion, since cerebrotendinous xanthomatosis manifests usually in patients under 30 years of age and in whom radical resection of tumors, and even of the tendon, has been recommended due to frequent recurrences . CONCLUSION In older patients with tumors that infiltrate the tendon, a less aggressive treatment can be chosen with a good clinical result.

Ruptura traumática aguda del tendón del cuádriceps tratado con sutura de alambre transpatelar / Acute traumatic rupture of the quadriceps tendon treated with transpatellar wire suture

Fundamento: La ruptura traumática aguda del tendón del cuádriceps es una entidad poco frecuente con una incidencia de 1,37/100 000 pacientes por año. Los hombres son los más afectados y la edad media de aparición ronda los 50 años. La cirugía ofrece los mejores resultados. Objetivo: Presentar un paciente con ruptura traumática aguda del tendón del cuádriceps derecho, con evolución favorable luego de una reparación primaria precoz con sutura transpatelar de alambre. Reporte de caso: Paciente masculino de 58 años de edad, con antecedentes de diabetes mellitus tipo II, que sufrió caída de sus pies. Acudió al servicio de urgencias con dolor intenso a nivel de la rodilla derecha, e imposibilidad para la marcha. A la exploración física se encontró impotencia absoluta para la extensión de la pierna derecha y signo del surco en la zona del tendón del cuádriceps.

Osteotomía calcánea con cuña de sustracción dorsal como tratamiento quirúrgico en la tendinopatía insercional de Aquiles / Dorsal wedge calcaneal osteotomy as surgical treatment for insertional Achilles tendinopathy

OBJETIVO: La osteotomía calcánea con cuña de sustracción dorsal tiene como objetivo reducir la longitud del calcáneo, elevando la inserción del tendón de Aquiles, reduciendo así la tensión en su inserción por la verticalización del calcáneo. El objetivo del estudio es evaluar los resultados clínicos de esta osteotomía en pacientes con tendinopatía insercional de Aquiles y un ángulo de inclinación del calcáneo elevado. MATERIAL Y MÉTODOS: Estudio retrospectivo de 18 pacientes con diagnóstico de tendinopatía insercional del tendón de Aquiles. Realizamos una doble osteotomía calcánea en forma de cuña dorsal, exéresis de esta y síntesis con 2 tornillos canulados. Se evaluaron los resultados clínicos-funcionales mediante las escalas EVA, AOFAS, VISA-A y satisfacción del paciente pre- y posquirúrgicas. Los parámetros radiológicos analizados fueron el ángulo de inclinación del calcáneo, la longitud del calcáneo y ángulo de Fowler-Philips. Se realizó un análisis estadístico mediante Stata 15. La media de seguimiento fueron 18,3 meses (rango 14-36). RESULTADOS: Todos los pacientes presentaron mejoría objetiva de los síntomas y de las escalas EVA (de 8,25 a 2,16 puntos) y AOFAS (de 41,5 a 86,5 puntos) con significación estadística (p < 0,05). La persistencia de calcificaciones intratendinosas en las radiografías postoperatorias no influyó en la mejoría sintomática. CONCLUSIONES: Con los resultados obtenidos consideramos que la osteotomía calcánea con cuña de sustracción dorsal es una técnica alternativa válida en el tratamiento de la tendinopatía insercional de Aquiles, sobre todo en los casos con un ángulo de inclinación del calcáneo elevado

OBJECTIVE: The dorsal wedge calcaneal osteotomy aims to reduce the length of the calcaneus and elevate the insertion of the Achilles tendon, leading to a reduction of Achilles tension in its insertion. The purpose of this study is to assess the clinical and functional results of this osteotomy in patients with insertional Achilles tendinopathy and a high calcaneal inclination angle. MATERIAL AND METHODS: This is a retrospective study with 18 patients diagnosed with insertional Achilles tendinopathy, who were treated by dorsal wedge calcaneal osteotomy, excision of the wedge and fixation with 2 cannulated screws. The VAS, AOFAS ankle-hindfoot, VISA-A and patient satisfaction scales were performed preoperatively and postoperatively. The radiological parameters analysed were the calcaneal inclination angle, the calcaneal length and the Fowler-Philips angle. A statistical analysis was performed. The mean follow-up was 18.3 months (range 14-36). RESULTS: All patients reported relief from symptoms. The VAS scale improved from 8.25 to 2.16 points; and the AOFAS score rose from 41.5 to 86.5 points (P<.05). The presence of tendon spurs on postoperative x-rays was not related to the clinical improvement. CONCLUSIONS: Based on the results that we present, the dorsal wedge calcaneal osteotomy can be considered an alternative procedure for insertional Achilles tendinopathy in patients with a high calcaneal inclination angle. The symptomatic relief of all the patients might be secondary to the reduction of the tendon tension in its insertion
