OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

OBJECTIVE: To explore the clinical efficacy of reconstruction the anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon for the treatment of chronic lateral ankle instability. METHODS: The clinical data of 42 patients with chronic lateral ankle instability treated by anatomical reconstruction of anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon from July 2016 to July 2019 was retrospectively analyzed. Including 30 males and 12 females, age ranged from 25 to 46 years old with an average of (37.6±12.4) years. There were 15 cases of left foot and 27 cases of right foot, the time from injury to operation was 3 to 12 months with a mean of (7.4±2.8) months. And 14 patients had tenderness in lateral collateral ligament area, 28 patients complained of multiple ankle sprains while walking on the flat ground. At 12 months after operation, the talar tilt angle and visual analogue scale(VAS)were observed, ankle joint varus stress and anterior drawer test were performed to check the mechanical stability of the ankle joint, American Orhopaedic Foot and Ankle Society(AOFAS) was used to score the ankle and hindfoot functions and evaluate the curative effect. RESULTS: Forty patients were followed up for 12 to 48 months with an average of (28.3±10.0) months, 2 cases were lost. The VAS decreased from(4.50±0.93) scores before surgery to (1.10±0.30) scores at 12 months after surgery;the talar tilt angle was reduced from (12.26±1.13)° before operation to (4.60±0.45)° at 12 months after operation;the AOFAS score increased from (65.10±7.50)scores before surgery to (84.40±3.95) scores at 12 months after surgery;all the differences were statically significant(P<0.05). According to the AOFAS score, 27 cases got excellent results, 7 good, 5 fair, and 1 poor. One patient had the symptoms of sural nerve injury after operation, and the symptoms were relieved after oral Mecobalamin for 3 months. The remaining patients had no complications such as nerve injury, infection, and skin necrosis. There was no instability of ankle joint, and both ankle varus stress test and drawer test were negative. CONCLUSION Autologous peroneal brevis tendon with double bone channel pass through the tendon (modified Chrisman-Snook operation) can anatomically reconstruct the anterior talofibular ligament and the calcaneofibular ligament, restore the stability of the patient's ankle joint, reduce postoperative complications, and restore ankle joint function well.

OBJECTIVE: To explore clinical effects of single-tunnel pullout structure fixation and anatomical reconstruction of lateral ligament complex in treating chronic lateral ankle instability. METHODS: From January 2016 to December 2018, clinical data of 23 patients with chronic lateral malleolus instability who underwent anatomical reconstruction of lateral malleolus ligament complex with single-tunnel pullout structure fixation, were retrospectively studied. Among them, including 7 males and 16 females, aged from 17 to 33 years old with an avergae of (26.0±4.3) years old;16 patients classified to grage 0, and 7 patients classified to gradeⅠaccording to Kellgren-Lawrence(K-L) grading;the time of sprain ranged form 2 to 15 with an average of (5.7±2.9) times;the time from injury to operation ranged to 4 to 18 months with an average of (9.0±3.3) months. The range of movement of operative and uninjured ankle joints were measured at 24 months after opertaion, visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) were used to evaluate ankle joint function and improvement of pain, K-L grading and MRI scoring of osteoarthritis of ankle (MSOA) were used to evaluate degree of cartilage degeneration of ankle joint. RESULTS: All patients were followed up from 24 to 48 months with an average of (33.4±6.7) months. All the anterior talofibular ligaments and calcaneofibular ligaments were dissected and reconstructed by single-tunnel pullout structure fixation. The range of motion of dorsiflexion, plantarflexion, varus, and valgus on the operative side of ankle joint were smaller than those on the healthy side. There were no statistically differences in dorsiflexion and eversion between operative side and healthy side of ankle joint ( CONCLUSION Treatment of chronic lateral ankle instability with reconstruction of lateral ligament complex with single-tunnel pullout structure fixation could provide better tendon and bone healing conditions, improve surgical safety and could achieve satisfactory clinical outcomes.

OBJECTIVE: To explore clinical effect of repairing anterior talofibular ligament with knot-free anchors under total ankle arthroscopy in treating chronic lateral ankle instability. METHODS: From April 2018 to August 2021, 24 patients with chronic lateral ankle instability were treated with knot-free anchors under total ankle arthroscopy to repair anterior talofibular ligament, including 16 males and 8 females, aged from 22 to 42 years old with an average of(28.6±5.8) years old;the time from injury to opertaion ranged from 6 to 10 months with an average of(7.7±1.3) months. Preoperative and postoperative American Orhopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), talar tilt, anterior talar translation(ATT) were recorded and compared. RESULTS: All patients were followed up from 10 to 12 months with an average of (10.2±1.14) months. Incision were healed at stageⅠ, and no infection, nerve injury and lateral ankle instability occurred. AOFAS score improved from(52.79±8.96) before opertaion to (93.00± 4.01) at 6 months after operation, 23 patients got excellent result and 1 good;VAS decreased from (5.50±0.98) before opertaion to (1.04±0.80) at 6 months after operation(P<0.05);talar tilt decreased from(9.16±2.09)° to (3.10±1.72)° at 3 months after operation(P<0.05);ATT decreased from(8.80±2.55) mm to (2.98±1.97) mm at 3 months after operation(P<0.05). Twenty-four patients drawer test and varus-valgus rotation wer negative. CONCLUSION Repairing anterior talofibular ligament with knot-free anchors under total ankle arthroscopy for the treatment of chronic lateral ankle instability has advantages of less trauma, less complications safe and reliable, and good recovery of ankle joint function.

OBJECTIVE: To investigate the mid-to-long-term efficacy of patients with chronic ankle instability combined with posterior impingement syndrome after 3-9 years of follow-up, and to analyze the influencing factors. METHODS: From February 2010 to December 2015, 46 patients underwent concurrent lateral ankle ligament repair with posterior ankle arthroscopic surgery at the Institute of Sports Medicine, Peking University Third Hospital. The patient was first placed in a prone position and underwent arthroscopic debridement for the posterior impingement. After finishing the posterior arthroscopy, the surgeon and assistants first translated the patient to the affected side, then turned to the healthy side, and changed the position to the supine position. During the turning over, another assistant held the arthroscope and the instrument to ensure that it was sterile and could be used without replacement. The anterior ankle arthroscopy was operated if necessary and the lateral ankle ligament repair was anatomic repaired with anchors. The 42 patients were followed up, including 26 males and 16 females. The average age was (28.9±10.0) years. The patient's clinical symptoms, joint stability, mobility and motor function were compared by questionnaire and physical examination. The preoperative and postoperative visual analogue scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) scores, Tegner scores were compared, and the clinical scores and the patient age, gender, height and weight were compared. The correlations between body mass index (BMI), preoperative duration, surgery duration, and cartilage injury were analyzed. RESULTS: The mean follow-up time was (71.8±22.8) months. The postoperative VAS scores (1.0 vs. 5.0, P<0.001), AOFAS scores (92 vs. 80, P<0.001), and Tegner scores (6.5 vs. 2, P<0.001) were significantly superior to the preoperative levels. The excellent and good rate was 97.6%. The postoperative VAS score (t=2.719, P=0.10), AOFAS score (t=-2.853, P=0.10), Tegner score (t=-3.443, P=0.001) and time to return exercise (t=2.814, P=0.008) were negatively correlated with the patient age, and the postoperative VAS score was negatively correlated with cartilage injury (Z=-2.195, P=0.028). CONCLUSION The mid-to-long-term clinical outcomes of the chronic ankle ligament instability combined with the posterior impingement were good. The age of the patients was negatively correlated with the clinical outcome. The combined cartilage injury could aggravate the postoperative pain.

PURPOSE: To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS: A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS: There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

OBJECTIVE: To measure anatomical data of calcaneofibular ligament (CFL), relevant data of CFL attachment to provide an anatomical basis for CFL reconstruction. METHODS: Twenty-seven adult ankle specimens were selected, including 11 males and 16 females, aged from 22 to 71 years old with an average of (41.6±17.2) years old;9 cases on the left side and 18 cases on the right side. The specimens reserved at least 20 cm above ankle joint and a complete foot, and exclude deformities, fractures, incomplete development and degenerative lesions. CFL was performed detailed anatomical observation, morphological parameters of CFL was measured, and coordinates of fibula side and calcaneal side of CFL in the coordinate axis were measured. The distance between fibula insertion of CFL and fibula tip, distance between calcaneal insertion of CFL and lateral calcaneal nodule, and Angle between CFL and long axis of fibula were also measured. RESULTS: In these 27 specimens, CFL cases were all single bundles and the length of CFL was (32.83 ± 8.19) mm. The center point of fibula attachment in CFL was(2.87± 1.21) mm proximal with a coefficient of variation of 42.16% and (2.08±1.34) mm anteriorly with a coefficient of variation of 64.42%. The center point of calcaneal attachment region of CFL was located on coordinate axis on the distal end (15.32±5.33) mm, with a coefficient of variation of 34.79%, and the posterior part (6.38±2.15) mm, with a coefficient of variation of 33.86%. The distance between center point of fibula attachment and fibula tip was (4.81±0.82) mm. The distance between center point of calcaneal attachment area of CFL and lateral calcaneal nodules was(17.25±3.12) mm. Angle between CFL and fibula axis is (43 ±18)° . CONCLUSION According to anatomical studies, we could locate the fibula and calcaneal attachment of CFL by anatomical markers around ankle joint. However, the location of CFL attachment has a large variation, and the anatomical characteristics need to be considered in anatomical reconstruction.

PURPOSE: Many techniques have been described for the reconstruction of chronic lateral collateral ligament (LCL) rupture with different autograft options. The advantages of percutaneous LCL reconstruction include small incisions, minimal soft tissue disruption, less postoperative pain, and speedy rehabilitation and recovery. The aim of this study was to report the functional outcome of percutaneous LCL reconstruction and overall patient satisfaction in Africans. METHODS: This prospective and interventional study involving 51 patients with chronic LCL rupture who had percutaneous LCL reconstruction using peroneus longus autograft was conducted between January 2021 and December 2022 in National Orthopaedic Hospital, Dala-Kano, Nigeria. The inclusion criteria were patients between the ages of 18 and 45 years with chronic isolated LCL and not more than 1 injury of knee ligament. Exclusion criteria were active infection, and multi-ligament knee injury requiring 2-staged surgery. The knee functions were assessed preoperatively, 3 months, 6 months, and 12 months postoperatively using the Lysholm scoring system. Patient satisfaction with the outcome of the treatment was assessed using a 5-point Likert scale. Relevant information was recorded into Microsoft Excel sheet and data was analyzed using SPSS version 23.0 for windows. The paired samples t-test was used to compare the clinical outcomes as continuous variables. Statistical significance was considered at p < 0.05. RESULTS: The mean age of the patients was (30.10 ± 5.90) years. The median time from injury to surgery was 7 months (ranging from 3 to 28 months). The mean follow-up period was (14.07 ± 3.13) months. The mean preoperative and 1-year postoperative Lysholm scores were 44.33 ± 12.97 and 97.96 ± 1.23, respectively. CONCLUSION Percutaneous LCL reconstruction using peroneus longus autograft significantly improves patient knee function and results in excellent patient satisfaction.

OBJECTIVETo compare clinical outcomes between two suturing methods using non absorbable materials through drilling the bone and suturing anchors for the treatment of complete rupture of the deltoid ligament.

METHODSFrom January 2009 to January 2013, 58 hospitalized patients with ankle fracture combined with complete rupture of the deltoid ligament were treated with suturing using non absorbable materials through drilling the bone or suturing anchors. There were 29 patients who received suturing treatments using non absorbable materials through drilling the bone (Group A), including 18 males and 11 females, with an average age of (39.76 +/- 11.81) years old. According to the Lauge-Hansen classification, 12 patients had supination external rotation (SER) injuries with IV degree, 5 patients had pronation external rotation (PER) injuries with III degree, 10 patients had PER injuries with IV degrss, and 2 patients had pronation abduction injuries with III degree. There were 29 patients who received treatments with suturing using anchors (Group B), including 14 males and 15 females, with an average age of (41.79 +/- 13.28) years old. According to the Lauge-Hansen classification,9 patients had SER injuries with IV degree, 6 patients had PER injuries with III degree,13 patients had PER injuries with IV degree, and 1 patient had pronation abduction injuries with III degree. All the patients were treated with open reduction and internal fixation, as well as reconstruction of deltoid ligaments to restore the stability of the medial ankle structures. The clinical examination, imaging evaluation, American society for ankle surgery (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) were used to evaluate the clinical results after operation, and the results of the two groups were compared and analyzed statistically.

RESULTSThe follow-up duration of the 58 patients ranged from 23 to 40 months,with an average of 27.3 months. All the patients had fracture union, and the mean healing time was 12.3 weeks (ranged, 10 to 17 weeks). There were no incision complications and ankle instability. There were no significant differences between two groups in AOFAS (P=0.666) and the VAS (P=0.905).

CONCLUSIONTreatments of complete rupture of the deltiod ligaments with the two suturing methods get similar good clinical effects, but the suturing using non absorbable materials through drilling the bone has several advantages such as reducing the financial burden of patients, saving social medical resources and avoiding the shortcoming in difficult removal of anchor suture.
