ObjectiveTo investigate effect of posterior oblique ligament (POL) repair on the rotational stability of the knee joint for the medial collateral ligament (MCL) combined with anterior cruciate ligament (ACL) ruptures.MethodsThe clinical data of 50 patients (50 knees) with grade-3 MCL-ACL combined injuries who met the selection criteria between January 2013 and December 2015 were retrospectively analyzed. All ACLs were reconstructed with autogenous tendon and the superficial and deep layers of MCLs were sutured; then, POLs were also sutured in 25 patients of repair group and only received conservation treatment postoperatively in 25 patients of conservation group. There was no significant difference in gender, age, disease duration, and preoperative KT-1000 measuring, medial joint space opening, International Knee Documentation Committee (IKDC) score, visual analogue scale (VAS) score, and knee range of motion between the two groups (P>0.05).ResultsAll incisions of the two groups healed by first intention, no surgical related complications occurred. All patients were followed up, with follow-up time of 28-56 months (mean, 38.1 months) in repair group and 26-55 months (mean, 29.1 months) in conservation group. At last follow-up, the IKDC score, VAS score, KT-1000 measuring, medial joint space opening, and knee range of motion significantly improved in the two groups when compared with preoperative ones (P<0.05); but there was no significant difference between the two groups (P>0.05). The Slocum test showed that there was no instability of the anterior medial rotation in the two groups.ConclusionThe POL repair can’t obtain more medial stability after ACL reconstruction and MCL repair (superficial and deep layers) for patients who have MCL-ACL combined injuries.
Objective To review the injury mechanism and the treatment progress of terrible triad of the elbow, and to analyze the direction of further research. Methods Related literature concerning terrible triad of the elbow was extensively reviewed and comprehensively analyzed. Results The main treatment of terrible triad of the elbow is operation. The ultimate goal of treatment is to reconstruct sufficient stability of the elbow. The treatment includes fixation of the coronoid by suture, screw or plate; fixation of radial head by screw and plate, partial or complete replacement of the radial head; fixation of lateral collateral ligament and the medial collateral ligament by bone suture or anchors and the application of the external fixator. These surgical treatments have their own indications and advantages, most get satisfactory results. Conclusion Generally, surgery is needed to maintain the stability of the elbow for patients of terrible triad elbow. However, medial ligament repair or not, the choice of approach, and mechanism of injury still need further study.
ObjectiveTo investigate the operative method and short-term effectiveness in the surgical treatment of Maisonneuve fracture. MethodsBetween January 2010 and February 2013, 23 patients with Maisonneuve fracture were treated. There were 14 males and 9 females with an average age of 40.3 years (range, 30-68 years). The causes of injuries were falling injury in 11 patients, sports related injury in 5 patients, traffic accident injury in 4 patients, and falling injury from height in 3 patients. The interval between injury and operation was 7-10 days (mean, 8.5 days). All of fractures were closed. Three patients had combined injury of deltoid ligament. The surgical procedures included surgical reduction and fixation of medial malleolus fracture and posterior malleolus fracture, repair of the deltoid ligament with ground anchor suture, and fixation of the disrupted distal tibiofibular syndesmosis. ResultsAll incisions achieved primary healing, no postoperative complications such as infection occurred. Twenty-one patients were followed up 24-36 months (mean, 26.5 months). No patients complained of pain, tenderness, and obvious swelling of the ankle. At 3-6 months (mean, 4.6 months) after operation, X-ray films showed bony union of fractures and normal mortises in 21 patients. And no traumatic arthritis was observed with reliable fixation. The range of motion of ankle dorsi flexion and plantar flexion was 30-40° (mean, 34.5°). Baird-Jackson ankle functional score was 85-100 (mean, 94); 16 cases were rated as excellent, 4 as good, and 1 as fair with an excellent and good rate of 95.2%. ConclusionSurgical treatments of Maisonneuve fracture include surgical reduction and fixation of the medial malleolus and posterior malleolus, repair of the deltoid ligament and fixation of the disrupted distal tibiofibular syndesmosis, and good effectiveness can be achieved.
Objective To discuss the effectiveness of operation technique for antero-medial rotatory instability (AMRI) of the knee joint caused by motorcycle. Methods Between June 2007 and December 2009, 32 cases of AMRI caused by motorcycle were treated. There were 28 males and 4 females with an average age of 35.5 years (range, 20-50 years). The interval between injury and surgery was 5-10 days (mean, 7 days). The anterior cruciate ligament (ACL) was injured at the attachment point of the condyles crest; the medial collateral ligament (MCL) was injured at central site in 19 cases, at medial condyles of femur in 10 cases, and at medial condyles of tibia in 3 cases, which were all closed injuries. The bone avulsion of condyles crest was fixed by steel wire and MCL was repaired. Results Red swelling and a little effusion occurred at the incision in 1 case, and the other incisions healed by first intention. Traumatic arthritis of the knee occured in 5 cases. Thirty-two cases were followed up 16-22 months (mean, 18.5 months). The X-ray examination showed that the fracture union time was 5-8 weeks (mean, 6 weeks) after operation. At last follow-up, the extension of knee joint was 0° and the flexion of the knee joint was 110-170° (mean, 155°). According to the synthetic evaluating standard of International Knee Documentation Committee, 24 cases were rated as A level, 6 cases as B, 1 case as C, and 1 case as D at last follow-up. Lysholm knee score was 85.93 ± 3.76 at last follow-up, which was significantly higher (t=53.785, P=0.000) than preoperative score 37.54 ± 3.43. Conclusion In patients with AMRI caused by motorcycle, steel wire is used to fix the bone avulsion of condyles crest and MCL should be repaired simultaneously as far as possible. And associating with the early postoperative functional exercise, the short-term effectiveness is satisfactory, but long-term effectiveness still need further follow-up observation.
Objective To investigate the cl inical outcome of treating dorsal wrist gangl ion with an improved surgical strategy by excising the gangl ion completely along their stalk and repairing the dorsal carpal l igaments under brachial anesthesia. Methods From March 2005 to January 2007, 34 patients with dorsal wrist gangl ion were treated and studied retrospectively. There were 14 males and 20 females, aged 25-65 years (43 years on average). The left sides were involved in 22 cases and right sides in 12 cases. Thirteen cases of relapse received excision for 1 to 4 times under local anesthesia, with amean period of 17 months (14 days to 7 years) from excision to recurrence. Twenty-one patients were first attack cases with a mean period of 11 months (15 days to 8 years) from diagnosis to excision. The size of the gangl ion ranged from 1.5 cm × 1.2 cm to 4.5 cm × 4.0 cm. Now, each surgical process was performed under brachial anesthesia, and a pneumathode tourniquet was used. In 6 patients, the stalks of gangl ion did not invade the carpal l igaments, and gangl ion was removed completely without immobil ization after operation. In 28 patients, the stalks of gangl ion invaded the carpal l igaments, gangl ion was excised completely along its stalk to the dorsal carpal structure; the l igaments were sutured directly in 16 cases and were repaired with adjacent tissue such as the wall of sheathing canal of extensor tendon in 12 cases. The wrists were immobil ised for 3 weeks. Results Primary wound heal ing was achieved in all incisions. All patients were followed up for 26-36 months with an average of 31.5 months. Only 2 cases (5.9%) recurred. The range of motion of the wrist remained normal and the symptom of the dorsal wrist was rel ieved sl ightly. Patients’ satisfaction score ranged from 60 to 100, with an average of 83.8. Conclusion The gangl ion should be excised completely together with defect repair of dorsal carpal l igament under brachial anesthesia and the wrist immobil ised for 3 weeks, the recurrence rate will be reduced greatly.
ObjectiveTo compare the effectiveness of all-arthroscopic technique and modified open Broström technique in repair of anterior talofibular ligament (ATFL) for lateral instability of the ankle (LIA).MethodsA retrospective analysis was made on 65 patients who underwent ATFL repair with anchors for LIA between January 2014 and January 2017. The ATFL was repaired by all-arthroscopic technique in 35 patients (arthroscopic group) and modified open Broström technique in 30 patients (open group). There was no significant difference in age, gender, the side of injured ankle, the time from injury to operation, and preoperative anterior displacement of talus, tilt angle of talus, the Karlsson Ankle Functional (KAF) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Japanese Society for Surgery of the foot ankle-hindfoot (JSSF) scale score between the two groups (P>0.05). The operation time, the intraoperative bleeding volume, and the length of time for surgery recovery were recorded. The anterior displacement of talus, the tilt angle of talus, KAF score, AOFAS score, and JSSF scale score were evaluated at 2 weeks, 3 months, and the last follow-up.ResultsAll patients were followed up 24-30 months, with an average of 26 months. The operation time, intraoperative bleeding volume, and the length of time for surgery recovery of arthroscopic group were superior to open group (P<0.05). There were 2 cases of temporary ankle and dorsum numbness and 1 case of thread reaction in arthroscopic group; and there were 2 cases of temporary ankle and dorsum numbness and 2 cases of thread reaction in open group. The AOFAS score, KAF score, and JSSF scale score in arthroscopic group were significantly higher than those in open group (P<0.05) at 2 weeks after operation; there was no significant difference between the two groups at 3 months and the last follow-up (P>0.05). There was no significant difference in the anterior displacement of talus and the tilt angle of talus between the two groups at 2 weeks, 3 months, and last follow-up (P>0.05).ConclusionCompared with the modified open Broström technique, the all-arthroscopic technique, as a minimally invasive technique, can achieve the same effectiveness, and has the advantages of shorter operation time, less intraoperative bleeding, and less pain in the early stage.
ObjectiveTo investigate effectiveness of allogeneic tendon of " W” type knit in repair of traumatic anterior dislocation of sternoclavicular joint.MethodsBetween June 2013 and June 2017, 12 patients with traumatic anterior dislocation of sternoclavicular joint after poor conservative treatment were treated with allogeneic tendon of " W” type knit. Of them, 10 were males and 2 were females, aged from 25 to 58 years (mean, 42 years). All injuries were caused by traffic accidents. The time from injury to operation was 4-12 weeks (median, 6 weeks). All of them were closed injuries. The patients had no fracture around the shoulder, or blood vessels, nerves, and other adjacent limb joint injuries. The operation time, intraoperative blood loss, incision healing, and complications were recorded. The sternoclavicular joint was observed by X-ray film and CT at 1 year after operation. Visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, Rockwood score, modified Hospital for Special Surgery (HSS) score, and Constant-Murley score were used to evaluate the function of shoulder joint after operation.ResultsThe operation time was 60-80 minutes (mean, 70 minutes). The intraoperative blood loss was 50-100 mL (mean, 60 mL). Primary healing of incision was obtained in all patients without complications. All the patients were followed up 12-24 months (mean, 18 months). At 1 year after operation, X-ray film and CT examination showed that the position of sternoclavicular joint was satisfactory. At 1 year after operation, the Rockwood score was 12-14 (mean, 13). The UCLA score was 28-34 (mean, 31). The VAS score was significant lower than that before operation (P<0.05), and the Constant-Murley score and modified HSS score were significantly higher than those before operation (P<0.05).ConclusionThe repair of traumatic anterior dislocationr of sternoclavicula joint with allogeneic tendon of " W” type knit can effectively reconstruct the stability of the joint, retain the physiological fretting, and obtain satisfactory results.
ObjectiveTo evaluate the effectiveness of repairing the deltoid ligament with ankle fracture. MethodsBetween January 2010 and January 2013, 11 patients with ankle fractures associated with deltoid ligament injury were treated. There were 7 males and 4 females, with an average age of 38.2 years (range, 18-72 years). The interval between injury and operation was 6 hours to 7 days (mean, 4 days). According to Lauge-Hansen classification, ankle fracture was rated as pronation-external rotation type in 5 cases, as supination-external rotation type in 4 cases, and as pronation-abduction type in 2 cases. The MRI and color Doppler ultrasound showed deltoid ligament rupture. The results of valgus stress test, talus valgus tilt test, and anterior drawer test after anesthesia were all positive. Fracture was treated by open reduction and internal fixation, and deltoid injury was repaired. ResultsAll incisions healed primarily. All patients were followed up 12-18 months (mean, 13.3 months). The X-ray films showed anatomical reduction, good position of internal fixation and stable distal tibiofibular syndesmosis. The mean fracture union time was 7.6 weeks (range, 6-8 weeks). MRI at 3 months after operation showed normal shape of the deltoid ligament. According to American Orthopaedic Foot and Ankle Society (AOFAS) score, the results were excellent in 6 cases, good in 3 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 81.8%. ConclusionIt is an effective method to treat ankle fracture with deltoid ligament injury by open reduction and internal fixation of ankle fracture and repair of the deltoid ligament injury, which can effectively rebuild medial instability and has satisfactory effectiveness.
Objective To investigate effectiveness of simplified all-arthroscopic Broström technique in treatment of chronic lateral ankle instability in adolescents. Methods A clinical data of 21 adolescent patients with chronic lateral ankle instability, who met the selection criteria and were admitted between June 2023 and May 2024, was retrospectively analyzed. There were 18 males and 3 females with an average age of 16.0 years (range, 13-18 years). There were 9 cases of left ankle joint injury and 12 cases of right ankle joint injury. Anterior talofibular ligament (ATFL) injury was diagnosed by arthroscopy in all patients. There were 11 cases of cartilage injury, 5 cases of avulsion fractures, and 6 cases of ankle impingement syndrome. The time from first sprain to operation ranged from 3-60 months (mean, 12.0 months). The ATFL was repaired and the ankle joint stability was restored by simplified all-arthroscopic Broström technique. Visual analogue scale (VAS) score, Tegner score, American Orthopaedic Foot and Ankle Society (AOFAS) score, Karlsson ankle function scale (KAFS) score, Foot and Ankle Outcome Score (FAOS) were used to evaluate ankle pain and function. MRI was used to evaluate the ligament healing. Results All patients were followed up 8-15 months (mean, 12.6 months). After operation, 1 patient suffered from superficial peroneal nerve injury, 1 patient developed anterior scar impingement on the ankle, 2 patients had superficial wound infection, and 1 patient suffered from sprain again. The VAS score, Tenger score, AOFAS score, KAFS score, and FAOS score significantly improved when compared with the preoperative scores (P<0.05). MRI examination showed the ligament healing and good tension. Conclusion For adolescent patients with chronic lateral ankle instability, using simplified all-arthroscopic Broström technique to repair ATFL can effectively alleviate ankle pain, improve stability, and achieve good effectiveness.
