Supramalleolar osteotomies for ankle arthritis: a systematic review.

INTRODUCTION: We investigated the mid-term outcomes of supramalleolar osteotomies regarding "survivorship" [before ankle arthrodesis (AA) or total ankle replacement (TAR)], complication rate and adjuvant procedures required. MATERIAL AND METHODS: PubMed, Cochrane and Trip Medical Database were searched from January 01, 2000. Studies reporting on SMOs for ankle arthritis, in minimum of 20 patients aged 17 or older, followed for a minimum of two years, were included. Quality assessment was performed with the Modified Coleman Methodology Score (MCMS). A subgroup analysis of varus/valgus ankles was performed. RESULTS: Sixteen studies met the inclusion criteria, with 866 SMOs in 851 patients. Mean age of patients was 53.6 (range 17-79) years, and mean follow-up was 49.1 (range 8-168) months. Of the arthritic ankles (646 ankles), 11.1% were classified as Takakura stage I, 24.0% as stage II, 59.9% as stage III and 5.0% as stage IV. The overall MCMS was 55.2 ± 9.6 (fair). Eleven studies (657 SMOs) reported on "survivorship" of SMO, before arthrodesis (2.7%), or total ankle replacement (TAR) (5.8%) was required. Patients required AA after an average of 44.6 (range 7-156) months, and TAR after 36.71 (range 7-152) months. Hardware removal was required in 1.9% and revision in 4.4% of 777 SMOs. Mean AOFAS score was 51.8 preoperatively, improving to 79.1 postoperatively. Mean VAS was 6.5 preoperatively and improved to 2.1 postoperatively. Complications were reported in 5.7% (44 out of 777 SMOs). Soft tissue procedures were performed in 41.0% (310 out of 756 SMOs), whereas concomitant osseous procedures were performed in 59.0% (446 out of 756 SMOs). SMOs performed for valgus ankles failed in 11.1% of patients, vs 5.6% in varus ankles (p < 0.05), with disparity between the different studies. CONCLUSIONS: SMOs combined with adjuvant, osseous and soft tissue, procedures, were performed mostly for arthritic ankles of stage II and III, according to the Takakura classification and offered functional improvement with low complication rate. Approximately, 10% of SMOs failed and patients required AA or TAR, after an average of just over 4 years (50.5 months) after the index surgery. It is debatable whether varus and valgus ankles treated with SMO reveal different success rates.

Endoscopic debridement for non-insertional Achilles tendinopathy with and without platelet-rich plasma.

BACKGROUND: When non-operative management fails to improve symptoms in patients with non-insertional Achilles tendinopathy, surgery may be required. Various open and endoscopic techniques have been proposed, and platelet-rich plasma (PRP) injections have been proposed as an adjunct to aid tendon healing. METHODS: Thirty-six patients with mid-portion Achilles tendinopathy were randomized to undergo endoscopic debridement alone (n = 19) or in combination with intraoperative PRP application (n = 17). Clinical outcome measures included the Visual Analogue Scale for pain, function, and satisfaction and the Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire. Patients were followed-up at 6 weeks, 3 months, 6 months, and 12 months after surgery. An MRI examination at 3 and 12 months was used to assess signal alterations within the tendon. RESULTS: Both groups showed significant clinical improvement (p < 0.05) after surgery, with no difference between the 2 groups. Tendon diameter increased at 3 months and decreased at 12 months. The tendinopathy area increased at 3 months and decreased at 12 months below baseline level in both groups. There was no significant difference between the groups regarding the MRI parameters. Nodular thickening and MRI-detected signal alteration persisted after surgery, with no association between imaging and clinical outcome. Five minor complications were reported: 2 in the PRP group and 3 in the control group. CONCLUSION: Endoscopic debridement of the Achilles tendon improved clinical outcomes in patients with mid-portion tendinopathy. The addition of PRP did not improve outcomes compared to debridement alone. MRI parameters showed no association with clinical outcomes.

Primary augmentation of percutaneous repair with flexor hallucis longus tendon for Achilles tendon ruptures reduces tendon elongation and may improve functional outcome.

PURPOSE: Achilles tendon ruptures (ATR) result in loss of strength and function of the gastrosoleus-Achilles tendon complex, probably because of gradual tendon elongation and calf muscle atrophy, even after surgical repair. Flexor hallucis longus (FHL) augmentation not only reinforces the repair and provides new blood supply to the tendon, but also protects the repair, internally splinting the repaired Achilles tendon, maintaining optimal tension. We prospectively compared the clinical outcomes of patients with acute ATR, managed with either percutaneous repair only or percutaneous repair and FHL augmentation. METHODS: Patients with acute ATR undergoing operative management were divided into two groups. Thirty patients underwent percutaneous repair under local anesthesia, and 32 patients underwent percutaneous repair augmented by FHL tendon, harvested through a 3 cm longitudinal posteromedial incision, and transferred to the calcaneus, under epidural anesthesia. All patients were treated by a single surgeon between 2015 and 2019 and were followed prospectively for 24 months. RESULTS: The percutaneous only group was younger than the augmented one (35.4 ± 8.0 vs 40.4 ± 6.6 years, p = 0.01). In the augmented group, 25 patients stayed overnight and only 5 were day cases, whereas in the percutaneous only group 4 patients stayed overnight and 28 of them were day cases (p < 0.001). The duration of the procedure was significantly longer in the augmented group (38.9 ± 5.2 vs 13.2 ± 2.2 min, p < 0.001). At 24 months after repair, the Achilles tendon resting angle (ATRA) was better in the augmented group (-0.5 ± 1.7 vs -4.0 ± 2.7, p < 0.001), as was Achilles tendon rupture score (ATRS) (91.7 ± 2.2 vs 89.9 ± 2.4, p = 0.004). Calf circumference of the injured and the non-injured leg did not differ between the groups, as did the time interval to single toe raise and the time interval to walking in tiptoes. Although plantarflexion strength of the operated leg was significantly weaker than the non-operated leg in both groups, the difference in isometric strength of the operated leg between the groups was not significant at 24 months (435 ± 37.9 vs 436 ± 39.7 N, n.s.). CONCLUSION: Percutaneous repair and FHL tendon augmentation may have a place in the management of acute Achilles tendon ruptures, reducing tendon elongation and improving functional outcome. LEVEL OF EVIDENCE: Level II.

Total hip arthroplasty for an intracapsular femoral neck fracture of high-femoral amputee.

Femoral neck fractures in transfemoral amputees are not common and management is associated with surgical technique and post-operative rehabilitation challenges. A 61-year-old Caucasian, male, above-knee amputee (following mangled extremity trauma 8 months before) who mobilized with a prosthesis presented to the emergency department with a right femoral neck fracture (Garden III). The patient underwent cementless total hip replacement (THR), using the lateral (Hardinge's) approach. No additional instrument was used to manipulate the residual femoral stump. The absence of the distal limb required careful preparation of the femoral canal, taking into consideration the position of the lesser trochanter, in order to appropriately align the femoral prosthesis regarding anteversion. Postoperative recovery was uneventful. Six months later, the patient was ambulating using his prothesis and had almost returned to his pre-injury activity status. Satisfactory results can be obtained after THR in trans-femoral amputees.

The Cincinnati incision is safe and effective for revision surgery for insertional tendinopathy of the Achilles tendon.

The present study reports the outcomes of revision surgery using a Cincinnati incision with tendon debridement and calcaneoplasty for insertional Achilles tendinopathy (IAT) in a cohort of patients at 24-month follow-up. Patients undergoing revision surgery following failed previous surgery for IAT were prospectively recruited. Patients were assessed pre-operatively and at 3, 6,12 and 24 months. The Victorian Institute of Sport Assessment Scale for Achilles Tendinopathy (VISA-A), the EQ5D questionnaire and the visual analogue scale (VAS) were used for evaluation. Data from 33 patients with a mean age of 43.9 years old are reported. 27% (9 of 33 patients) were female. The left side was involved in 58% (19/33) of patients. No clinically relevant complications were reported in any of the patients. Most of subscales of EQ5D improved at last follow-up: Usual Activities (P = 0.01), Mobility (P = 0.03), Pain/Discomfort (P = 0.001), Thermometer (P = 0.04). No statistically significant change for the subscales Self-Care (P = 0.08) and Anxiety-Depression (P = 0.1) was evidenced. The VISA-A score improved significantly at last follow-up (P < 0.0001), as did the VAS score (P < 0.0001). These results indicated that a Cincinnati incision followed by tendon debridement and calcaneoplasty for revision surgery for IAT is feasible and reliable, achieving clinically relevant improvement in the VISA-A, EQ5D and VAS at 24 months follow-up.

Effect of macronutrients and of anaerobic digestate on the heterotrophic cultivation of Chlorella vulgaris grown with glycerol.

The aim of this work was to investigate the kinetics of the heterotrophic growth of Chlorella vulgaris as a means of producing bio-oil for biodiesel production. Glycerol was used as the sole organic carbon substrate. Anaerobic digestate from a local plant was used to examine its effect on the kinetics and the protein and lipid content of the biomass. The effect of the initial carbon and nitrogen concentrations on the carbon uptake rate was studied independently. In the one set of five experiments, the organic carbon in the form of glycerol varied from 0.27 to 5.36 g L-1, while the concentration of atomic nitrogen was held constant and equal to 45.4 mg L-1. The Co/No ratio varied from 6 to 118.1. In the second set, also of five experiments, the organic carbon was held constant and equal to 3.3 g L-1 and atomic nitrogen varied from 22.7 to 450 mg L-1. The Co/No ratio varied from 7.3 to 145.4. In the third set of experiments, anaerobic digestate was added in increasing amounts into the culture media from 4 to 16%. It was found that the carbon uptake rate as well as the lipid and protein content depended on the Co/No ratio. Increasing ratios of Co/No led to higher carbon uptake rates, higher lipid content, and lower protein content. The initial nitrogen concentration was also found to affect the growth rate of C. vulgaris. The addition of anaerobic digestate did not affect appreciably the protein and lipid content of the biomass, while the addition of anaerobic digestate up to 16% in the culture medium increased the carbon uptake rate by about 24%.

Slowed-Down Rehabilitation Following Percutaneous Repair of Achilles Tendon Rupture.

BACKGROUND: Following percutaneous repair of acute Achilles tendon (AT) ruptures, early postoperative weightbearing is advocated; however, it is debatable how aggressive rehabilitation should be. We compared the clinical and functional outcomes in 2 groups of patients who followed either our "traditional" or a "slowed down" rehabilitation after percutaneous surgical repair. METHODS: Sixty patients were prospectively recruited to a slowed down (29 patients) or a traditional (31 patients) rehabilitation program. Both groups were allowed immediate weightbearing postoperatively; a removable brace with 5 heel wedges was applied at 2 weeks. In the slowed-down group, 1 wedge was removed after 4 weeks. Gradual removal of the boot took place after 4 wedges were kept for 4 weeks. In the traditional group, 1 wedge was removed every 2 weeks, with removal of the boot after 2 wedges had been kept for 2 weeks. The AT Resting Angle (ATRA) evaluated tendon elongation. Patient reported functional outcomes were assessed using the AT Rupture Score (ATRS). Calf circumference difference and the isometric plantarflexion strength of the gastro-soleus complex were evaluated. RESULTS: At the 12-month follow-up, both ATRA and ATRS were more favorable in the slowed-down group. The isometric strength and the calf circumference were more similar to the contralateral leg in the slowed-down group than in the traditional one. CONCLUSION: Following percutaneous repair of acute Achilles tendon patients undergoing slowed down rehabilitation performed better than the traditional one. These conclusions must be considered within the limitations of the present study. LEVEL OF EVIDENCE: Level II, prospective comparative study.

Arthroscopic Subtalar Joint Arthrodesis: Topical Review.

BACKGROUND: Advances in foot and ankle arthroscopy over the last 2 decades have allowed for subtalar joint arthrodesis to be performed arthroscopically. The potential advantages of the arthroscopic technique include higher fusion rates, lower complications, reduced perioperative morbidity, and accelerated rehabilitation. Arthroscopic arthrodesis may, however, not be appropriate in the setting of complex deformity correction or the need for other open procedures. METHODS: Surgical techniques of arthroscopic subtalar joint arthrodesis are described. Outcomes and complications associated with these procedures are presented, based on a comprehensive literature review. Thirteen Level IV studies of moderate quality were included. RESULTS AND CONCLUSION: Excellent arthrodesis union rates were achieved (average 96%, range 86%-100%), at a weighted average union time of 8.8 weeks (95% confidence interval 7.9-9.7). The overall complication rate was 21% (87/415 feet; range 10%-36.4%). Metal irritation was the most common complication (11.2%), followed by nerve injury (4.2%) and infection (0.9%). Similar fusion rates have been reported when comparing arthroscopic and open arthrodesis. Complication rates are also similar, excerpt for infection, which may be lower with arthroscopy. Three different approaches were used to access the subtalar joint with similar union and complication rates. There was no evidence that the use of bone graft or more than 1 screw improved outcomes. The superiority of arthroscopic subtalar fusion over open techniques cannot be demonstrated by the available studies. LEVEL OF EVIDENCE: Level IV, case series.

Outcomes of management of displaced intra-articular calcaneal fractures.

Despite the advances in operative management, displaced intra-articular calcaneal fractures (DIAFCs) are often associated with long term sequelae, permanent disability, a considerable reduction in quality of life, and a high socio-economic cost. Randomized controlled trials have shown that patient reported outcomes of surgery are no better than those of nonoperative management. Methodological flaws and selection bias may have influenced the results, however, and subgroup analysis showed that some patients could benefit from surgery, whilst patients' preference can be the decisive factor in choosing a management modality. Fractures with significant lateral wall displacement predisposing to impingements often require surgery, and management has to be individualized and tailored to the patient. Surgery does not usually achieve excellent results, though it exposes the patient to potential risks and complications. Wound healing problems and infections affect around 20% of patients when the extensile lateral approach has been used. Sinus tarsi approach and minimally invasive surgery may be viable alternatives, offering similar results with fewer wound complications, but most of the available studies are of low to moderate quality. Late subtalar joint arthrodesis is often required: however, such procedure would be less technically difficult and could result in better foot function should the shape of the calcaneus have been anatomically restored with surgery in the acute phase.

Modified Zadek osteotomy without excision of the intratendinous calcific deposit is effective for the surgical treatment of calcific insertional Achilles tendinopathy.

INTRODUCTION: Nonoperative management of calcific insertional Achilles tendinopathy (CIAT) may fail in 10-30% of patients, and various operative procedures have been described to manage those. METHODS: A modified Zadek (dorsal closing wedge) calcaneal osteotomy, without removing the calcific deposits and without detaching the insertion of the Achilles tendon, was performed between November 2016 and December 2017 in 25 consecutive patients (mean age 53.5 years), who were followed for at least 2 years. RESULTS: The osteotomies had united at an average of 5 weeks. Two superficial wound infections (8%) were documented. Patients had returned to their normal activities at an average time of 23 ± 7.7 weeks. Three out of four patients, who practised recreational sport activity, returned to their pre-injury level. VAS and VISA-A scores had significantly improved at 3 months postoperatively (p < .001) and continued to improve for 24 months. CONCLUSION: The modified Zadek osteotomy, without excision of the intra-tendinous calcification, was safe, and significantly improved clinical outcome in patients with CIAT at 2 years after surgery. Level of evidence IV.

Ankle fractures in diabetic patients.

Surgical complications are more common in patients with complicated diabetes (presence of inner organ failure, neuropathy).Of all patients undergoing ankle fracture fixation, approximately 13% are diabetic and 2% have complicated diabetes mellitus.Non-operative management of ankle fractures in patients with complicated diabetes results in an even higher rate of complications.Insufficient stability of ankle fractures (treated operatively, or non-operatively) can trigger Charcot neuroarthropathy, and result in bone loss, deformity, ulceration, and the need for amputation.Rigid fixation is recommended. Hindfoot arthrodesis (as primary procedure or after failed ankle fracture management) can salvage the limb in approximately 80% of patients.Early protected weight bearing can be allowed, provided rigid fixation without deformity has been achieved.

Dorsally Based Closing Wedge Osteotomy of the Calcaneus for Insertional Achilles Tendinopathy.

BACKGROUND: Surgical management may be indicated for patients with insertional Achilles tendinopathy (IAT) after failure of nonoperative management, and various surgical techniques have been described. HYPOTHESIS: We present the technique and results of modified dorsal closing wedge calcaneal osteotomy, performed in a cohort of 28 consecutive patients. We hypothesized that this will be a safe procedure that can improve hindfoot pain and function for most patients who will return to preoperative daily life and sports activities. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A modified dorsal closing wedge osteotomy was performed in 28 patients (mean age, 54.7 years) from November 2015 to December 2016. All patients were followed for at least 2 years postoperatively. RESULTS: All osteotomies united at a mean of 5 weeks. The mean anatomic change in calcaneal length was 4 mm (range, 3-6 mm). The overall complication rate was 10.7%. There were 2 superficial wound infections (7.1%) and 1 instance of sural nerve-related paresthesia (3.5%) reported. All patients returned to their presurgical level of activities at a mean of 23 ± 8.0 weeks. Further, 3 of 4 patients who participated in recreational sports activities returned to their preinjury level. Visual analog scale and Victorian Institute of Sports of Australia-Achilles scores significantly improved postoperatively (P < .001) and continued to improve for 24 months. CONCLUSION: The modified dorsal closing wedge calcaneal osteotomy is a safe procedure and significantly improved pain and function in patients with IAT at 2 years after surgery.

Delayed (14-30 Days) Percutaneous Repair of Achilles Tendon Ruptures Offers Equally Good Results As Compared With Acute Repair.

BACKGROUND: Minimally invasive repair of acute Achilles tendon ruptures has been performed for several years, resulting in reduced morbidity as compared with open repair. HYPOTHESIS: A minimally invasive technique can be used to manage Achilles tendon ruptures in patients presenting between 14 and 30 days from injury. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We prospectively recruited 21 consecutive patients who presented between 14 and 30 days after the index injury, and we compared them with 21 patients who were matched according to sex, age (±2 years), and level of activity, who presented within 14 days of the index injury. All patients underwent the same minimally invasive procedure under local anesthesia: a core suture repair consisting of a modified Bunnell suture in the proximal stump and a modified Kessler suture in the distal stump. RESULTS: At 12 months after minimally invasive repair, patients with delayed treatment had a median Achilles tendon rupture score of 91 (SD, 2.4; range, 87-96) as compared with 91 (SD, 2.2; range, 86-96) in patients treated acutely, who presented at a median 2.4 days (range 1-6 days) from the injury. There were no significant differences between groups in terms of mean (SD) Achilles tendon resting angle: delayed repair group, -3.9° (2.0); acute repair group, -3.7° (1.9) (P = .69). No patient in either group developed a wound infection. One patient in the acute group experienced an iatrogenic sural nerve injury. CONCLUSION: Patients with Achilles tendon rupture treated by percutaneous repair 14 to 30 days after injury achieved similar results at 1 year as patient treated <14 after injury.

Ipsilateral free semitendinosus graft with interference screw fixation for surgical management of insertional acute Achilles tendon tears.

INTRODUCTION: Very distal tears of the Achilles tendon are uncommon, and poor quality tendinous tissue of the calcaneal stump can compromise healing. Little has been published about the characteristics and surgical management of such injuries. We present a surgical technique, developed by the senior author, to restore continuity of the gastrosoleus-Achilles tendon-calcaneus complex using a free ipsilateral semitendinosus graft, and clinical outcomes of a case series of 28 consecutive patients. Our hypothesis was that this is a safe technique, and patients can return to pre-injury occupation and athletic activities. PATIENTS AND METHODS: A total of 28 patients (mean age 46 years) underwent minimally invasive reconstruction using a free ipsilateral semitendinosus graft for acute insertional rupture of tendo Achillis. The procedure required two small incisions along the course of the Achilles tendon, and one posteromedial incision at level of the ipsilateral knee to harvest the semitendinosus tendon. Patients were assessed at minimum 2 years (range, 2-2.5 years) following the index procedure. RESULTS: The median Achilles tendon Rupture Score (ATRS) at the latest follow-up was 88. Two patients developed a superficial wound infection. All patients returned to their preinjury occupation, whilst 22 out of 28 patients (79%), returned to their preinjury level of physical activity at a mean of 6.7 months after surgery, reporting good or excellent overall satisfaction in 88.5% of cases. CONCLUSION: This minimally invasive technique was safe, and allowed most of patients to return to preinjury daily and sport activities within 9 months from surgery.

Midterm experience of Scarf osteotomy as a new technique in a General Orthopaedic Department.

Scarf osteotomy has become popular as a versatile procedure that could correct most cases of hallux valgus. The purpose of this study is to report the experience with scarf osteotomy performed as a new technique by different surgeons of a general orthopaedic department. This study reviewed the outcome of 67 patients with 78 feet with hallux valgus deformity treated by scarf osteotomy at our institution, with an average follow-up of 24 months (12-84). Results were analyzed by clinical examination, a questionnaire including the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score and plain radiographs. The mean AOFAS score increased from 35 points (range, 15-50) preoperatively to 87 points (range, 73-100) at the final follow-up. The radiological angles Hallux Valgus Angle (HVA), 1-2 Intermetatarsal Angle (IMA) and Tibial Sesamoid Position (TSP) improved significantly. Among the 7 recurrences and 15 complications recorded, seven required an additional procedure. Multiple potential pitfalls can occur with scarf osteotomy. Although soft tissue dissection is relative extensive, adherence to careful technique and endurance to the learning curve can produce effective radiological correction of hallux valgus and good clinical results. LEVEL OF CLINICAL EVIDENCE: III.

Morton's interdigital neuroma: instructional review.

The terminology 'Morton's neuroma' may represent a simplification of the clinical condition as the problem may not be a benign tumour of the nerve, but neuropathic foot pain associated with the interdigital nerve.Foot and ankle pathomechanics leading to metatarsalgia, clinical examination and differential diagnosis of the condition and imaging of the condition, for differential diagnosis, are discussed.Nonoperative management is recommended initially. Physiotherapy, injections (local anaesthetic, steroid, alcohol), cryotherapy, radiofrequency ablation and shockwave therapy are discussed.Operative treatment is indicated after nonoperative management has failed. Neuroma excision has been reported to have good to excellent results in 80% of patients, but gastrocnemius release and osteotomies should be considered so as to address concomitant problems.Key factors in the success of surgery are correct diagnosis with recognition of all elements of the problem and optimal surgical technique.

Stability in ankle fractures: Diagnosis and treatment.

Medial column (deltoid ligament) integrity is of key importance when considering the stability of isolated lateral malleolus ankle fractures.Weight-bearing radiographs are the best method of evaluating stability of isolated distal fibula fractures.Computed tomography (CT) scanning is mandatory for the assessment of complex ankle fractures, especially those involving the posterior malleolus.Most isolated trans-syndesmotic fibular fractures (Weber-B, SER, AO 44-B) are stable and can safely be treated non-operatively.Posterior malleolus fractures, regardless of size, should be considered for surgical fixation to restore stability, reduce the need for syndesmosis fixation, and improve contact pressure distribution.

Surgical management of chronic Achilles tendon ruptures using less invasive techniques.

BACKGROUND: Surgical management of chronic Tendo Achillis (TA) ruptures usually requires tendon grafting procedures. Several techniques have been described. We examined the outcome of three different less invasive (incisions length less than 3 cm) tendon transfer techniques in the management of patients with a chronic rupture of the TA. METHODS: Of 62 patients (39 males and 23 females; mean age 44.8 years; range 29.3-62 years) with chronic TA ruptures managed operatively, 21 patients had a ≥6cm gap and underwent free ipsilateral semitendinosus (ST) graft (21 patients), whereas patients with smaller gaps had either ipsilateral peroneus brevis (PB) (20 patients) or ipsilateral flexor hallucis longus (FHL) transfer (21 patients). Outcome measures included maximum calf circumference, isometric plantar flexion strength, and the Achilles tendon total rupture score (ATRS), preoperatively and at the last follow up. We also recorded the time to return to activities of daily living (ADL) and sports, and the number of single-leg heel lifts on the affected leg at the last follow up, at an average of 35.4 months. RESULTS: Patient characteristics between groups were similar. All outcome measures significantly improved after surgery (p<0.001), without differences between the three groups. Return to ADL was possible at an average of 4.5 months. Patients undergoing PB transfer had a slower return to sports compared to the other groups, at 6.9±0.5months versus 6.1±0.8 for the FHL and 5.8±0.6 for the ST groups (t-test p=0.005 and p<0.001, respectively). However, 13/14 patients (90%) in the PB group returned to high impact sports, compared to 9/12 (75%) in the FHL and 6/11 (55%) in the ST groups (Fisher's test, p=0.31 and p=0.056, respectively). CONCLUSION: All three techniques produced significant functional improvement, and return to sports was possible in most patients. This study does not demonstrate a clear advantage of one technique over the others.

Minimally Invasive Achilles Tendon Stripping for the Management of Tendinopathy of the Main Body of the Achilles Tendon.

Achilles tendinopathy is a common cause of disability. New nerves fibers grow from the paratenon into the Achilles tendon, and they could play a central role in the development of pain. We report the results of minimally invasive Achilles tendon stripping for Achilles tendinopathy in 47 active patients. The Victorian Institute of Sports Assessment-Achilles questionnaire score improved from 53.8 preoperatively to 85.3 postoperatively (p < .001). After a mean follow-up period of 40.5 months, 41 patients had resumed sporting activities at an average of 3.5 months postoperatively. A sural nerve injury was recorded in 5 patients (10.6%), and all 5 complications occurred during the first 12 cases. As a result, the technique was slightly modified, and no sural nerve neuropathy was observed subsequently. One superficial infection (2.1%) was recorded. Minimally invasive Achilles tendon stripping seems to be an effective, technically simple, and inexpensive treatment of Achilles tendinopathy. Further randomized controlled trials involving more patients are needed to confirm these outcomes.
