Comparative effectiveness of peroneus longus tendon (PLT) autografts versus hamstring tendon (HT) autografts in anterior cruciate ligament reconstruction: a comprehensive systematic review and meta analysis.

The hamstring tendon (HT) autograft is currently the most widely utilised autograft option for anterior cruciate ligament (ACL) reconstruction. However, recent studies endorse the peroneus longus tendon (PLT) autograft as a viable alternative. To evaluate this, we systematically reviewed randomised controlled trials (RCTs) to compare the efficacy of PLT against HT autografts. Our search encompassed Cochrane, Embase, OVID, PubMed, and Scopus databases for RCTs comparing outcomes of PLT and HT autografts in ACL reconstruction. Primary outcomes included Lysholm and International Knee Documentation Committee (IKDC)scores, while secondary outcomes involved American Orthopaedic Foot and Ankle Society (AOFAS)scores, graft diameters and donor-site complications. Statistical analysis was performed using Review Manager 5.4 (Cochrane Collaboration) and heterogeneity was assessed with I2 statistics. 683 patients from 6 RCTs were included, with 338 (49.5%) patients treated with PLT autografts. Follow-up ranged from 12 to 30months. Despite lower preoperative Lysholm scores in the PLT group, no significant differences were observed at 6 and 12months. Although preoperative and 6-month IKDC scores were lower in the PLT group, no significant differences were found at 12 and 24months. AOFAS scores showed no significant preoperative difference, but slightly lower scores were noted in the PLT group at 12 or 24months. There was no significant difference in graft diameter, while donor-site complications were fewer in the PLT group. In summary, the PLT autograft is a promising and non-inferior alternative to the HT autograft, demonstrating equivalent outcomes in patient-reported knee and ankle metrics, comparable graft diameters and fewer donor-site complications.

Application of three-dimensional ultrasound technique in repairing dorsal foot wounds with medial sural artery perforator flaps

To investigate the accuracy of positioning perforator of medial sural artery with three-dimensional ultrasound technique guided by a wide band linear matrix array volume transducer probe before operation, and the effectiveness of the flap design based on this in repairing the dorsal foot wounds. Between January 2019 and December 2022, 30 patients with skin and soft tissue defects of the dorsal foot were treated. There were 19 males and 11 females, with an average age of 43.9 years (range, 22-63 years). There were 12 cases of traffic accident injury, 15 cases of heavy crushing injury, and 3 cases of machine injury. The time from injury to hospitalization was 1-8 hours (mean, 3.5 hours). The wounds in size of 5 cm×3 cm to 17 cm×5 cm were thorough debrided and covered with vacuum sealing drainage dressing. Then the wounds were repaired with the medial sural artery perforator flaps after no obvious infection observed. To obtain the complete three-dimensional image, the number and position of the medial sural artery perforator branches and the position of the main blood vessels in the muscle were detected and recorded by wide band linear matrix array volume transducer probe before operation. Suitable perforating branches were selected to design the flap and guide the flap incision on this basis. The size of the perforating flap ranged from 6 cm×4 cm to 18 cm×6 cm. The sensitivity and positive predictive value were calculated by comparing preoperative exploration with intraoperative observation of perforating branches, so as to evaluate the positioning accuracy of three-dimensional ultrasound technique. The donor sites were sutured directly in 25 cases and repaired with free skin grafting in 5 cases. The 60 perforating branches of medial sural artery were found before operation and 58 during operation in 30 patients. Among them, pre- and intra-operative perforations were consistent with 56. The sensitivity was 93.3% and positive predictive value was 96.6%. The intramuscular position and route of the main blood vessels were basically consistent with the pre- and intra-operative observation. All flaps survived and wounds healed by first intention. All incisions at the donor sites healed by first intention, and all skin grafts survived. All patients were follow up 9-24 months (mean, 14.7 months). The appearance, color, and texture of the flaps were good, and no obvious effect on wearing shoes and walking. At last follow-up, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind score ranged from 80 to 92, with an average of 87.5. The patient satisfaction was excellent in 29 cases and good in 1 case. The three-dimensional ultrasound technique guided by the wide band linear matrix array volume transducer probe can accurately locate the perforating branch of the medial sural artery, and the three-dimensional imaging is more intuitive, which can be used to guide the design and incision of the medial sural artery perforator flap.

The learning curve for minimally invasive Achilles repair using the “lumbar puncture needle and oval forceps” technique

IntroductionAn acute Achilles tendon rupture represents a common tendon injury, and its operative methods have been developed over the years. This study aimed to quantify the learning curve for the minimally invasive acute Achilles tendon rupture repair.MethodsFrom May 2020 to June 2022, sixty-seven patient cases who received minimally invasive tendon repair were reviewed. Baseline data and operative details were collected. The cumulative summation (CUSUM) control chart was used for the learning curve analyses. Achilles tendon rupture score (ATRS), American Orthopedic Foot and Ankle Society (AOFAS) ankle/hindfoot score, and visual analog scale (VAS) at 3/6/9/12 months were calculated to assess the clinical outcomes.ResultsThirty-six cases underwent at least a year of follow up and were enrolled in this study. The gender ratio and average age were 80.5% and 32.5 years. The linear equation fitted well (R2 = 0.95), and CUSUM for operative time peaked in the 12th case, which was divided into the learning phase (n = 12) and master phase (n = 24). No significant difference was detected between the two groups in clinical variables, except for the operative time (71.1 ± 13.2 min vs 45.8 ± 7.2 min, p = 0.004). Moreover, we detected one case with a suture reaction and treated it properly.ConclusionMinimally invasive Achilles repair provides an opportunity for early rehabilitation. Notably, the learning curve showed that the “lumbar puncture needle and oval forceps” technique was accessible to surgeons.

Is it necessary to graft the void defect during open reduction and internal fixation of calcaneal fractures?

There are still controversies on the effect of grafting during open reduction and internal fixation of calcaneal fractures. The aim of this study was to compare the radiological and functional outcomes in patients with or without intraoperative grafting. In a comparative retrospective study, among 442 operatively-treated calcaneal fractures, 60 patients with unilateral closed sanders type II intraarticular calcaneal fracture who underwent ORIF via lateral extensile approach using locking anatomical plates with at least 1year follow-up without any postoperative wound complication were enrolled. The patients were separated into 2 groups: with bone allograft and without bone allograft. The functional outcome of the patients was assessed using visual analog scale (VAS) for pain, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, foot function index (FFI), and short-form (SF-36) health survey. Radiographic variables included Böhler angle, Gissane angle, calcaneal width, calcaneal height, and talar declination angle. Also, the differences (delta) of these values in comparison to the uninjured foot were calculated. The mean age was 39.1 ± 12.7 (range, 13-67) years with 54 males, 90.0%. No statistically significant differences were detected in age, gender, affected side, and subtypes of calcaneal fractures between the two groups (p > 0.05). The average follow-up was 25.1 (range, 12-48) months. The differences for all radiographic measurements and also, the delta values between the groups were not statistically significant, except talar declination angle which was more in cases without grafting (p = 0.007). Although the differences between the two groups regarding AOFAS ankle-hindfoot scale (p = 0.257), VAS for pain (p = 0.645), and FFI (p = 0.261) were not statistically significant; the group with bone graft experienced less pain (19.7 ± 22.0) than the other group (26.7 ± 22.8). The difference between the groups was not statistically significant (p = 0.87) according to the SF-36 questionnaire. Incorporating allografts into the void defects during ORIF of displaced intraarticular calcaneal fractures may not improve functional outcomes and recover postoperative radiological parameters. Therefore, routine use of allograft to fill the defects during ORIF of calcaneus may not be recommended. Of note, that these findings solely relate to the treatment of Sanders type II fractures. Comparative retrospective study.

Three-dimensional printed custom-made modular talus prosthesis in patients with talus malignant tumor resection

BackgroundTalar malignant tumor is extremely rare. Currently, there are several alternative management options for talus malignant tumor including below-knee amputation, tibio-calcaneal arthrodesis, and homogenous bone transplant while their shortcomings limited the clinical application. Three-dimensional (3D) printed total talus prosthesis in talus lesion was reported as a useful method to reconstruct talus, however, most researches are case reports and its clinical effect remains unclear. Therefore, the current study was to explore the application of 3D printed custom-made modular prosthesis in talus malignant tumor.MethodsWe retrospectively analyzed the patients who received the 3D printed custom-made modular prosthesis treatment due to talus malignant tumor in our hospital from February 2016 to December 2021. The patient's clinical data such as oncology outcome, operation time, and volume of blood loss were recorded. The limb function was evaluated with the Musculoskeletal Tumor Society 93 (MSTS-93) score, The American Orthopedic Foot and Ankle Society (AOFAS) score; the ankle joint ranges of motion as well as the leg length discrepancy were evaluated. Plain radiography and Tomosynthesis-Shimadzu Metal Artefact Reduction Technology (T-SMART) were used to evaluate the position of prosthesis and the osseointegration. Postoperative complications were recorded.ResultsThe average patients’ age and the follow-up period were respectively 31.5 ± 13.1 years; and 54.8 months (range 26–72). The medium operation time was 2.4 ± 0.5 h; the intraoperative blood loss was 131.7 ± 121.4 ml. The mean MSTS-93 and AOFAS score was 26.8 and 88.5 respectively. The average plantar flexion, dorsiflexion, varus, and valgus were 32.5, 9.2, 10.8, and 5.8 degree respectively. One patient had delayed postoperative wound healing. There was no leg length discrepancy observed in any patient and good osseointegration was observed on the interface between the bone and talus prosthesis in all subjects.ConclusionThe modular structure of the prosthesis developed in this study seems to be convenient for prosthesis implantation and screws distribution. And the combination of solid and porous structure improves the initial stability and promotes bone integration. Therefore, 3D printed custom-made modular talus prosthesis could be an alternative option for talus reconstruction in talus malignant tumor patients.

Factors predicting the outcome of arthroscopic debridement and microfracture technique in treatment of osteochondral lesions of talus

Aims and Scope: Osteochondral lesions of the talus (OLT) are common injuries that occur following ankle sprains and fractures. Surgical management, either through open or arthroscopic technique, is required to eliminate the pain and restore the ankle’s function. This study aims to evaluate the prognostic significance of demographic variables and lesion’s characteristics. Method and Techniques: In this study, 40 ankle (40 patients), who underwent arthroscopic debridement and microfracture technique to treat osteochondral lesion of the talus, were evaluated retrospectively after two years. The functional outcome of the ankle joint was assessed by using foot – ankle disability score, (FADS), pain analysing scale score (PASS), American orthopaedic foot and ankle society (AOFAS) score, and Ogilvie-Harris scaling system. Then the association between patients’ age and gender, and the lesions’ characteristics, including size, grade, and location, were evaluated. Results: Outcome results varied according to the scoring system, but all patients achieved satisfied outcome and pain relieve. Younger patients with smaller lesions achieved a better clinical result. All measures including PASS, AOFAS, Ogilvie-Harris, FADS appeared to be significantly better in smaller lesions. (P-value <0.05) PASS and Ogilvie-Harris scales showed better results in younger patients. Ogilvie-Harris test result was notably superior in the lateral lesions. Conclusion: The patient’s age and size of the lesion are two prognostic factors of arthroscopic debridement and microfracture of OLTs. We believe arthroscopic management can be associated with a better outcome in lesions smaller than 1.5 cm in diameter and patients younger than 40-years-old. Level of Clinical Evidence: Level 2 – prognostic study

Changes in Calcaneal Bone Density and Correlation With Clinical Outcomes Following Ankle Fractures

Introduction: The study investigates the long-term bone quality and its influence on clinical results after surgical treatment of Weber B-type fractures. Methods: Surgery treated isolated Weber B-type fractures between 2006 and 2016 were included. Bone density was determined by ultrasonography densitometry of the calcaneus. American Orthopedic Foot and Ankle Society (AOFAS), Foot Function Index, Olerud-Molander-Ankle-Score, Hannover-Score, and Short Form Health Survey SF 36 were recorded. Results: Sixty patients were followed up. Mean follow-up was 6.6 years (range, 2 to 12 years). Mean bone density T-score of the treated foot was significantly lower than that of the contralateral untreated side (−0.6 versus −0.3; P = 0.05). Higher T-scores on the injured side were significantly and positively correlated with improved outcomes in the AOFAS, Olerud-Molander-Ankle-Score, and SF-36 physical component summary but negatively correlated with the Hannover score (P ≤ 0.05). A significant correlation existed only between the pain scores of the AOFAS and Foot Function Index. Controlling for potential confounding variables, such as age and smoking status, in a linear regression model, increased bone density was only associated with the AOFAS score. Discussion: A significant reduction in bone density persists for more than eight years in some individuals. Statistically significant correlation between reduced bone density and clinical outcomes was found only for the AOFAS scoring system.

Clinical Study of a Four-Step Program for the Treatment of Plantar Fasciitis with Bone Spurs.

The most common causes of plantar and heel pain are plantar fasciitis and calcaneal spurs, and they often co-exist. Surgery is a recognized treatment for refractory plantar fasciitis. However, few studies have proposed treatment options for patients with metatarsophalangeal fasciitis with bone spurs. Accordingly, this study's purpose was to propose a four-step surgical regimen, and to improve the surgical outcome of plantar fasciitis with osteophytes and to establish a procedure for surgical treatment. Retrospective analysis of 45 patients suffering from plantar fasciitis with bone spurs from 2020 to 2023. All patients underwent a four-step procedure, including plantar fascia release, calcaneal spur grinding, inflammatory tissue removal, and calcaneal burr decompression. The imaging parameters and functional scores were recorded before and after the operation. The objective evaluation included the measurement of calcaneal spur length on radiographs. Clinical evaluation included the American Orthopaedic Foot and Ankle Society (AOFAS), the Visual Analog Scale (VAS), and the Foot and Ankle Outcome Scale (FAOS). Measurement data that conformed to normal distribution were expressed as (x2 ± s), and pre-and postoperative AOFAS, FAOS, and VAS scores were compared using repeated-measures ANOVA, and preoperative and postoperative spur lengths were compared using paired t-tests. The 45 patients were followed up for 3 to 30 months, (17.72 ± 8.53) months, at final follow-up, the patient's AOFAS score improved from preoperative (74.93 ± 5.56) to (94.78 ± 3.98), FAOS score increased from preoperative (76.42 ± 3.37) to (96.16 ± 2.74), the VAS score decreased from (3.18 ± 0.54) to (1.07 ± 1.20) (p < 0.05), the length of spur decreased from (0.72 ± 1.81) cm to (0.23 ± 1.19) cm, and there were significant differences before and after operation (p < 0.05). The four-step surgical regimen is an appropriate and effective surgical procedure to treat plantar fasciitis with bone spurs.

Treatment of bunionette deformity with distal oblique sliding osteotomy

Background: Tailor’s bunion is a bone prominence on the lateral side of the fifth metatarsal head, it is most often associated with soft tissue bursitis and a tender callosity. In the current series, we evaluated a technique of Distal Oblique Sliding Osteotomy using K-wire fixation. Materials and methods: We present a retrospective and consecutive series concerning six patients (six feet) suffering from symptomatic bunionette deformity treated through the DOSO with k-wire fixation. We describe this procedure, their results, and short-term follow-up. Results: At 12 months follow-up, the results were satisfactory in 5 feet, fair in one patient following the American Orthopaedic Foot and Ankle Society (AOFAS) score. The average preoperative intermetatarsal 4-5 angle improved from 14,5° (range, 8°-17°) to 5° (range, 5°-9°) and the fifth metatarsophalangeal angle improved from 16.2° (range, 10°-24°) to 3,5° (range, 2°-9°). Conclusion: This technique is versatile, cost-effective (can use a small piece of pins), safe and reliable in comparison to other types of bunionette osteotomy and their osteosynthesis.

Comparison of pain relief among patients with chronic plantar fasciitis treated with intralesional platelet-rich plasma injection versus corticosteroid injection in a tertiary care centre in Kerala - a prospective study

Background: Aim of the study was to compare pain relief and functional outcome and between intralesional autologous platelet rich plasma injection (PRP) versus corticosteroid injection in the treatment of plantar, and fasciitis by using visual analogue score and American Orthopaedic Foot and Ankle Society (AOFAS) score. Methods: The sample size for the study was 30 patients attending Dr. Somervell Memorial CSI Medical College. Patients were divided into two groups (PRP versus steroid) of 15 each. The study follows a prospective observational design with follow up at 2 weeks, 2 months and 3 months post procedure. The functional outcome of patients in each group was assessed using the visual analog scale and AOFAS score. Results: Post-procedure, a significant decrease in VAS score was seen in patients treated with PRP injection (8.73 to 2.27) than those treated with Steroid injection (8.8 to 3.53). Also, there was a significant improvement in the AOFAS score from 72.73 to 88.67 while for those patients treated with steroid injection, the AOFAS score was comparatively low (65.87 to 82.2). Conclusions: Plantar fasciitis is a prevalent condition in our community, and many treatment options typically offer only temporary relief from symptoms. Intralesional PRP injection emerges as a dependable treatment method that fosters the healing process of the affected fascia, resulting in improved functional outcomes. Our study indicates that a singular administration of platelet-rich plasma injection for plantar fasciitis yields substantial pain relief compared to the local steroid injection.

Comparison between intramedullary nail and conventional plate for displaced intra-articular calcaneal fractures: A meta-analysis.

This study aimed to compare the efficacy and safety of the intramedullary nail and conventional plate for the treatment of displaced intra-articular calcaneal fractures from clinical comparative trials. A comprehensive search of English databases was carried out in the Springer, PubMed, ScienceDirect, Web of Science, and Cochrane Library databases until September 2023. Studies on calcaneal fractures treated by an intramedullary nail or a plate were considered for inclusion. Endpoints included duration of operation, length of hospital stay, the Visual Analog Scale (VAS) score, postoperative functional score, radiological parameters, and complications. The mean difference (MD) and risk difference (RD) as the combined variables, as well as the 95% confidence intervals, (CIs) were calculated. Five retrospective controlled studies covering 473 feet at the one-year follow-up met the inclusion criteria. The meta-analysis demonstrated that there were significant differences in the duration of operation (MD: -10.81; 95% CI: -16.32, -5.31; p=0.0001), length of hospital stay (MD: -3.65; 95% CI: -4.35, -2.95; p<0.00001). No significant differences were found regarding postoperative American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale (MD: 0.36; 95% CI: -3.89, 4.61; p=0.87), VAS (MD: 1.95; 95% CI: -0.30, 4.21; p=0.09), or postoperative Böhler angle (MD: 0.94; 95% CI: -0.04, 1.92; p=0.06) between the two groups. The incidence of total complications (RD: -0.31; 95% CI: -0.46, -0.17; p<0.0001) and wound-healing complications (RD: -0.16; 95% CI: -0.30, -0.03; p=0.02) were lower in the intramedullary nail group. There were no significant differences in the incidences of revision surgery, implant removal, superficial wound infection, deep infection, and nonunion. Compared to conventional plates, the intramedullary nail showed a shorter duration of operation, reduced length of hospital stay, and fewer postoperative total complications and wound-healing complications in treating displaced intra-articular calcaneal fractures.

The Forgotten Joint Score Is a Valid Outcome Measure for Total Ankle Arthroplasty: A Prospective Study.

The success of total ankle arthroplasty (TAA) involves objective and subjective parameters such as joint motion and implant survival. Patient-reported outcome measures provide key context from the patient's perspective so that we can evaluate the results of these procedures. The Forgotten Joint Score (FJS) has demonstrated validity and reliability in other arthroplasties, but the existing evidence on the FJS in TAA is very limited. We aimed to assess the reliability, validity, responsiveness to change, and floor and ceiling effects, as well as to perform a gender analysis, of the FJS in patients who had undergone TAA. A prospective, observational study enrolled patients who underwent TAA at our institution between June 2021 and May 2023. The three-component TAA was performed through an anterior approach. A total of 120 patients (mean age 62 ± 10 years) participated, which was 83% (120 of 145) of those eligible, and 77% (92 of 120) of those patients underwent follow-up assessments at 12 ± 1 months after surgery. A cross-culturally adapted and validated version of the FJS in our language (Italian) was used. Additionally, three other commonly used patient-reported outcome measures for TAA were administered: the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the Manchester-Oxford Foot Questionnaire (MOXFQ), and the VAS. Reliability was demonstrated by excellent internal consistency (Cronbach α coefficient = 0.95) and excellent test-retest reliability (intraclass correlation coefficient = 0.99; standard error of measurement = 2.7). Robust validity was observed, in that the FJS had a strong correlation with the AOFAS ankle-hindfoot score, the MOXFQ, and the VAS (Pearson and Spearman values consistently above 0.7 or below -0.7). Responsiveness to change was observed between 6 and 12 months (Cohen d = 0.37). Low ceiling and floor effects at both 6 months (4% and 3% reached top and bottom scores, respectively) and 12 months (10% and 0% reached top and bottom scores, respectively) were demonstrated, below the recommended 15% interpretability threshold. No association between outcomes and patient gender was observed. Test properties and validity of the FJS were strong in patients who underwent TAA. It seems suitable for clinical use, although future studies should seek to replicate or refute our findings in other patient populations. Level II, therapeutic study.

Clinical observation of sinus tarsi syndrome after lateral ankle sprain

To study the incidence rate of sinus tarsi syndrome after lateral ankle sprain and observe the clinical efficacy of sinus tarsal corticosteroid injections. From January 2021 to Janury 2022, 391 patients with lateral ankle sprain and 88 patients with sinus tarsi syndrome using corticosteroid injections (compound betamethasone 1 ml+ lidocaine hydrochloride 4 ml) were retrospectively analyzed. There were 22 males and 66 females, aged from 29 to 60 years old with an average of (41.00±7.52) years old, duration of the disease from 1 to 12 months with an average of (5.6±4.2) months. The visual analogue scale(VAS) and American Orthopedic Foot and Ankle Society(AOFAS) scores were collected before, 1 month, 3 months, 6 months, and 12 months after treatment. All 88 patients completed a 12-month follow-up. The incidence rate of sinus tarsi syndrome after lateral ankle sprain was 22.5%. One month after treatment, VAS was 1.20±0.89, AOFAS score was 88.70±7.04. Three months after treatment, VAS was 1.60±1.35, AOFAS score was 85.20±10.95. Six months after treatment, VAS 2.35±1.39, AOFAS 80.30±9.75. Twelve months after treatment, VAS was 2.80±1.51, AOFAS score was 79.1±9.94. Significant differences were found before and after treatment at all four time points of follow-up(P<0.05). The results of this study showed that the incidence rate of sinus tarsi syndrome after lateral ankle sprain was 22.5%. Corticosteroid injections were effective in the short term with a 65% recurrence rate of symptoms within 1 year. For patients with no significant long-term effect of conservative treatment, clinicians may explore alternative approaches, including options like ankle arthroscopy.

Comparative study of minimally invasive titanium elastic nail and steel plate on the treatment of fracture of tibiofibular fracture in adults

To compare the clinical outcomes of using elastic intramedullary nail and plate to fix fibular fracture. The 60 patients with tibiofibular fractures admitted from January 2015 to December 2022 were divided into two groups:intramedullary nail group and plate group, 30 cases each, intramedullary nail group was treated with elastic intramedullary nail fixation group, plate group was treated with steel plate and screw fixation group. Intramedullary nail group, there were 18 males and 12 females, aged from 22 to 75 years old with an average of (39.4±9.8) years old, including 24 cases of traffic accidents injury, 6 cases of falling injury, 23 cases of closed fractures, 7 cases of open fractures. Steel plate group, there were 15 males and 15 females, aged from 24 to 78 years old with an average of (38.6±10.2) years old. The 22 cases were injured by traffic accident, 8 cases were injured by falling. The 24 cases were closed fractures and 6 cases were open fractures. The operation time, intraoperative bleeding, American Orthopedic Foot and Ankle Society (AOFAS) ankle and hind foot scores, clinical healing time of fibula and the incidence of wound complications were compared between the two groups. The patients in both groups were followed up for 6 to 21 months, with an average of (14.0±2.8) months. Compared with plate group, intramedullary nail group had shorter operative time, less bleeding, shorter clinical healing time of fibula, and lower infection rate of incision, and the difference was statistically significant (P<0.05). There were 2 cases of delayed healing in intramedullary nail group, 1 case of nonunion in plate group, and 2 cases of delayed healing in plate group, and there was no statistically significant difference between the two groups (P>0.05). In the last follow-up, according to the AOFAS scoring standard, the ankle function in intramedullary nail group was excellent in 17 cases, good in 12 cases, fair in 1 case, with an average of (88.33±4.57) points, while in plate group, excellent in 16 cases, good in 10 cases, fair in 4 cases, with an average of (87.00±4.14) points;There was no statistical difference between the two groups (P>0.05). Elastic intramedullary nail has the advantages of short operation time, less intraoperative bleeding, short fracture healing time and less incision complications in the treatment of fibular fracture, which is worthy of clinical application.

Comparison of tibial nerve pulsed radiofrequency and intralesional radiofrequency thermocoagulation in the treatment of painful calcaneal spur and plantar fasciitis: A randomized clinical trial.

Ultrasound-guided tibial nerve pulsed radiofrequency (US-TN PRF) and fluoroscopy-guided intralesional radiofrequency thermocoagulation (FL-RFT) adjacent to the painful calcaneal spur are two interventions for pain management in painful calcaneal spur (PCS) and plantar fasciitis (PF). This study aimed to compare the effectiveness of the two procedures. A prospective, randomized, single-blind study. Single-center pain clinic. Forty-nine patients who met the inclusion criteria were randomized into two groups. 25 patients (group U) received US-TN PRF at 42 °C for 240 s, while 24 patients (group F) received intralesional FL-RFT at 80 °C for 90 s. The most severe Numeric Rating Scale (NRS) score during the first morning steps and the American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scores were used to evaluate the effectiveness of the procedures. The study's primary outcome assessed treatment effectiveness using the NRS, whereas the secondary outcomes included changes in the AOFAS score and the incidence of procedure-related mild adverse events. NRS and AOFAS scores significantly improved in groups U and F at 1 and 3 months compared to baseline (p < 0.05), and there was no significant difference between the groups. At month 1, 50% or greater pain relief was achieved in 72% of patients in group U and 75% in group F. No significant difference was observed in the incidence of mild adverse events between the groups. US-TN PRF and intralesional FL-RFT have shown significant effectiveness in the treatment of PCS and PF. Larger randomized controlled trials are needed.

The Efficacy of Anterior Cruciate Ligament Reconstruction with Peroneus Longus Tendon and its Impact on Ankle Joint Function.

Peroneus Longus Tendon (PLT), a viable anterior cruciate ligament (ACL) graft, shares similar biomechanics, making it suitable for reconstruction. Controversy exists over whether PLT transplants affects the donor ankle joint. The purpose of this study was to examine the recovery of knee joint function following arthroscopic ACL restoration using autologous PLT and its influence on the donor ankle joint. A retrospective analysis was conducted on 65 patients with ACL rupture who underwent PLT graft reconstruction in our hospital from January 2016 to December 2021. A three-dimensional gait analysis of the bilateral knee and ankle joints was performed postoperatively using an Opti_Knee three-dimensional motion measurement and analysis system-Yidong Medical Infrared Motion Gait Analyzer. Knee function scores and changes in the range of motion of the bilateral knee and ankle joints were collected. The analysis of preoperative and postoperative joint function scores, bilateral knee and ankle mobility was performed by t-tests. One year after surgery, the patients' International Knee Documentation Committee (IKDC) scores, Knee Injury and Osteoarthritis Outcome Scores (KOOSs), and Lysholm scores were significantly improved compared to preoperative scores, with statistically significant differences (p < 0.05). There was no statistical difference in the American Orthopedic Foot and Ankle Society (AOFAS) score of the donor ankle joint before and after surgery (p > 0.05). During different gait cycles, there was no statistical difference in knee joint mobility between the affected and healthy sides (p > 0.05), but there was a statistical difference in the inversion and eversion angle of the donor ankle joint during the support phase (p < 0.05). ACL reconstruction using the PLT can yield satisfactory knee joint function. However, it does affect inversion and eversion in the donor ankle joint, necessitating postoperative exercises. Similar subjective function ratings for both operated and non-operated feet, despite increased inversion-eversion motion in the operated foot, may be influenced by the subjective nature and margin of error in the AOFAS Ankle-hindfoot score, along with the relatively small variation in ankle inversion-eversion angles.

Ankle arthrodesis through minimally-invasive transfibular approach: a new surgical technique.

The purpose of our work was to demonstrate the surgical technique of ankle arthrodesis using the minimally-invasive transfibular (MITF) approach, which minimizes soft tissue damage and is advantageous for high-risk patients. In this prospective study, a total of 12 patients with end-stage varus ankle osteoarthritis, including high-risk individuals, underwent ankle arthrodesis using the MITF approach. The technique involves a unique osteotomy at the joint space level, minimizing soft tissue detachment from the fibula. The primary outcomes assessed included bony union, time to weight-bearing, correction of varus deformity, and functional outcomes measured by the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scale. However, the study's limitations encompass a small sample size and the absence of a control group. At 6months post-operation, all patients achieved bony union, with a mean time to union of 13.7 ± 5.2weeks. The average time to initiate weight-bearing without additional support was 11.2 ± 3.8weeks. Preoperative varus deformity (17.08 ± 8.36 degrees) and talar tilt (8.75 ± 4.33 degrees) were successfully corrected, with postoperative alignment within 0-5 degrees of valgus. Functional outcomes showed a significant improvement in AOFAS scores from 37.83 ± 7.79 points preoperatively to 77.42 ± 5.63 points one year after surgery (p = 0.002). Minor complications occurred in two patients, both effectively treated with local therapy and antibiotics. The MITF approach for ankle arthrodesis demonstrates promising results in addressing end-stage varus ankle osteoarthritis, even in high-risk patients. However, the study's limitations highlight the need for a prospective comparative clinical trial with a larger sample size to ascertain the technique's effectiveness and safety definitively.

Effectiveness comparison of a new hook-shaped anatomical locking plate and conventional anatomical locking plate in treatment of Danis-Weber type A lateral malleolus fractures

To investigate the effectiveness of a new hook-shaped anatomical locking plate in the treatment of Danis-Weber type A lateral malleolus fractures. A retrospective analysis was performed on the clinical data of 45 patients with Danis-Weber type A lateral malleolus fractures who met the selection criteria between November 2020 and November 2022. According to the surgical methods, they were divided into the observation group (treated with the new hook-shaped anatomical locking plate, 23 cases) and the control group (treated with the conventional lateral malleolus anatomical locking plate, 22 cases). There was no significant difference in baseline data such as gender, age, cause of injury, Danis-Weber type of fracture, time from injury to operation, and combined ligament injury between the two groups ( P>0.05). The operation time, partial weight-bearing time, return to work time, and postoperative complications were recorded and compared between the two groups. The function and pain of ankle joint were evaluated by the range of motion of ankle dorsiflexion, plantarflexion, varus, valgus, and visual analogue scale (VAS) score at 1 and 3 months after operation, and at last follow-up, and the American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 months after operation and at last follow-up. All patients were followed up 10-18 months (mean, 15.1 months). There was no significant difference in operation time between the two groups ( P>0.05); the postoperative partial weight-bearing time and return to work time of the observation group were significantly earlier than those of the control group ( P<0.05). During the follow-up, there was 1 case of joint stiffness in the observation group, and 1 case of joint surface displacement, 1 case of joint stiffness, and 1 case of traumatic arthritis in the control group. There was no significant difference in the incidences of complications between the two groups ( P>0.05). With the extension of time after operation, the range of motion of ankle dorsiflexion, plantarflexion, varus, valgus, and VAS score of the two groups gradually improved, and there were significant differences between different time points ( P<0.05); At 1 and 3 months after operation, the above indexes in the observation group were significantly better than those in the control group ( P<0.05), and there was no significant difference between the two groups at last follow-up ( P>0.05). The difference of AOFAS score between the last follow-up and 3 months after operation in the observation group was significantly better than that in the control group ( P<0.05). Compared with the conventional lateral malleolus anatomical locking plate, the new hook-shaped anatomical locking plate has a more reliable fixation effect in the treatment of Danis-Weber type A lateral malleolus fracture, which is conducive to early functional exercise of the ankle joint, so that patients can bear weight earlier and return to work earlier, and the operation time is not significantly prolonged, and the effectiveness is satisfactory.

Effectiveness of transverse double "8"-shaped tension band technique for Lawrence zone Ⅰ fracture of the fifth metatarsal base

To explore the effectiveness of transverse double "8"-shaped tension band technique in the treatment of Lawrence zoneⅠfracture of the 5th metatarsal base. Between February 2019 and October 2021, 15 patients with Lawrence zoneⅠfracture of the 5th metatarsal base were treated with transverse double "8"-shaped tension band technique. There were 8 males and 7 females, with a median age of 40 years (range, 23-59 years). The fractures were caused by sprains. The time from injury to operation was 3-7 days (mean, 4.1 days). X-ray films were taken to observe the fracture healing and the anchor looseness and detachment. The foot function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) score, and the eversion angle of the calcaneal talus joint. The incisions healed by first intention after operation in 14 cases and the incision healed poorly in 1 case. All patients were followed up 8-12 months (median, 10 months). The imaging examination showed that all fractures healed well, with a healing time of 10-14 weeks (mean, 11.7 weeks). At last follow-up, AOFAS score was 82-100 (median, 98); 13 cases were excellent and 2 cases were good, with an excellent and good rate of 100%. VAS score was 0-3 (median, 1). Three cases had mild limited ankle joint range of motion, while 12 cases had normal range of motion. The eversion angle of the calcaneal talus joint was 25°-32° (median, 30°). The application of transverse double "8"-shaped tension band technique for Lawrence zone Ⅰ fracture of the 5th metatarsal base has advantages such as simple operation, avoidance of secondary operation, and reduction of foreign body sensation, with definite effectiveness.

PHYSICAL THERAPY IS AN INTEGRAL PART OF THE SURGICAL TREATMENT OF VALGUS DEFORMITY OF THE FIRST TOE

Objective. Determining the effectiveness of physical therapy in the surgical treatment of valgus deformity of the first toe. Methods. The clinical material of the conducted study includes 38 observations, 34 patients (38 operative interventions, 4 patients — on 2 feet. In the control group (CG) there were 16 patients (16 interventions), and in the main group (MG) — 18 patients (22 interventions). All patients who participated in the study had the same diagnosis — hallux valgus II–III degree. All patients received the same type of surgical intervention — a variant Z-shaped osteotomy of the first metatarsal bone according to the Scarf method or Chevron, which was supplemented with osteotomy of proximal phalanges of the I finger to Akin method. Patients were examined with the Visual-Analogue Scale (VAS), the Physiotherapy Clinical Outcome Variables (COVS) Motor Skills Testing Scale, and the American Orthopedic Foot and Ankle Society (AOFAS) Scale (module 2) for the Clinical Evaluation of Foot and Ankle Diseases of the American Foot and Ankle Association. Rehabilitation of MG patients consisted of developed physical therapy (PT) program, which included 4 periods. Rehabilitation included not only massage and exercises for the muscles of the front part of the foot, but also a complex of rehabilitation methods aimed to restore the function of the muscles of both lower limbs, hips and buttocks. PT program for KG consisted only of morning hygienic gymnastics, classical massage and therapeutic exercises to restore function of muscles of the foot and lower leg. Results. Assessment of the condition of patients after the end of PT on the COVS scale helped to conclude that the patients of MG have significantly better indicators of general physical activity than patients of CG. Analysis of the obtained results according to the (AOFAS) Scale confirmed that patients of MG after using developed PT program have statistically better results. Conclusions. The developed PT program significantly accelerate the clinical recovery of function not only the front part of the foot, but also general working capacity of patients.
