The surgical treatment of massive rotator cuff tears is a clinical challenge for orthopaedic surgeons. Moreover, tendon retraction, adhesions and fatty infiltration after rotator cuff tear will further increase the difficulty of surgical repair. Therefore, it has become a hotspot and difficulty to repair massive rotator cuff tears with a better way in current research. In recent years, with the continuous development of arthroscopic techniques, shoulder arthroscopic surgery has become the gold standard for the treatment of massive rotator cuff tears, but the adaptations, effects and combined application of different surgical methods are still controversial. The author believes that arthroscopic debridement of shoulder joint and acromioplasty or tuberoplasty could relieve shoulder pain in the short-term for elderly patients with lower functional requirements;long biceps tenotomy or tenodesis is effective for patients with biceps long head tendon injury; complete repair is still the first line treatment for massive rotator cuff tears, but partial repair is possible for massive rotator cuff tears that could not be completely repaired;patch augmentation technology could bring good results for young patients with high functional requirements;for patients with limited internal and external rotation of the shoulder joint and high functional requirements, tendon transfers surgery is recommended;superior capsular reconstruction is more advantageous for young patients with no obvious glenohumeral arthritis, better deltoid muscle strength and higher functional requirements. In addition, subacromial spacer implantation has become a current research hotspot due to its advantages of small trauma, low cost and relative safety, and its long-term effect still needs to be further confirmed.

PURPOSE: Defects around the distal one third of the leg and ankle are difficult to manage by conservative measures or simple split thickness skin graft. Distally based peroneus brevis muscle flap is a well described flap for such defects. METHODS: This is a retrospective analysis conducted on 25 patients with soft tissue and bony defects of distal third of lower leg and ankle, which were treated using distally based peroneus brevis muscle flap from January 2013 to January 2018. Information regarding patient demographics, etiology, size and location of defects and complications were collected. All patients were followed up for at least 3 months after surgery. RESULTS: There were 21 males and 4 females with the mean age of 39 (5-76) years. The most common cause of injuries was road traffic accident, followed by complicated open injury. The average size of defects was 20 (4-50) cm. The mean operating time was 75 (60-90) min for flap harvest and inset. We had no patient with complete loss of the flap. Five patients (20%) had marginal necrosis of the flap and two patients have graft loss due to underlying hematoma and required secondary split thickness skin grafting. CONCLUSION The distally based peroneus brevis muscle flap is a safe option with reliable anatomy for small to moderate sized defects following low velocity injury around the ankle. The commonest complication encountered is skin graft loss which can be reduced by primary delayed grafting.

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

OBJECTIVETo investigate the clinical effect of lateral superior genicular composite tissue flap for tissue defect.

METHODSThe axis line of flap is the lateral thigh vertical midline. The cutaneous branch is inserted 4 cm near the femoral lateral epicondylus. The anterior border is the elongation line along patellar lateral border. The posterior margin is the hinder margin of femoral biceps. The lower border is the horizontal line along the upper line of patella. The composite flaps were used in 18 cases with soft tissue defects in extremities, 11 cases with clacaneus tenden defects and 16 cases with bony nonunion. Results From Mar. 2002 to Sept. 2013, 45 cases were treated with the composite tissue flaps. The flaps size ranged from 6 cm x 3 cm to 17cm x 9 cm. All the flaps survived completely. Blood supply crisis happened in 2 cases, which was released by reanastomosis. The patients were followed up for 1 - 2. 5 years with satisfactory aesthetic and functional results. All the bone defect and nonunion were healed. Good healing was also achieved in donor sites. 8 months after operation, knee joint function is evaluated as good by hospital special surgery knee score (HSS).

CONCLUSIONLateral superior genicular compostie tissue flap can be used to reconstruct soft tissue defect, bone defect and tenden calcaneus defect in one stage.

OBJECTIVETo investigate the effect of reverse saphenous nerve neurocutaneous flaps for skin defects of forefoot.

METHODSIn the anatomic study, 50 cadaveric feet were injected with red latex and the anastomosis, distribution and external diameters of medialtarsal artery, medial anterior malleolus artery, medial plantar artery, the superficial branch of the medial basal hallucal artery and saphenousnerve nutritional vessels were observed. Based on anatomic research results, we designed the reverse saphenous nerve neurocutaneous flaps for repairing skin defects of forefoot.

RESULTSThe blood supply of reverse saphenous nerve neurocutaneous flaps were based on the vasoganglion, which consist of arterial arch at the superior border of abductor hallucis and arterial network on the surface of abductor hallucis around the saphenous nerve and medial pedis flap. From Oct. 2006 to Oct. 2011, the reverse saphenous nerve neurocutaneous flaps were used to repair skin defects of forefoot in 11 cases. The flap size ranged from 2.5 cm x 3.5 cm to 7.5 cm x 8.5 cm. The wounds at donor site were covered with full-thickness skin graft. All flaps survived completely with no ulcer at the donor site. 11 cases were followed up for 6 to 18 months( mean, 10 months). The skin color and texture were satisfactory. The patients could walk very well.

CONCLUSIONSIt is reliable to repair the skin defects of forefoot with reverse saphenous nerve neurocutaneous flaps. It is easily performed with less morbidity. This flap should be considered as a preferential way to reconstruct skin defects of forefoot.

OBJECTIVETo explore selection and method of tissue flaps for the repair of severe defects of skin and soft tissue around the knee joints.

METHODSFifty-four patients with wounds around the knee joints, all accompanied by exposure or necrosis of tendon or bone and exposure of prosthesis, were hospitalized in our burn center from June 2008 to December 2014. Five of them were with knee joint injury. After thorough debridement or tumor resection, the wound area ranged from 5 cm × 5 cm to 46 cm × 22 cm. Three patients were repaired with free latissimus dorsi myocutaneous flaps, 7 were repaired with modified sartorius myocutaneous flaps, 8 were repaired with gastrocnemius myocutaneous flaps, one was repaired with gastrocnemius muscle flap, two were repaired with posterior leg flaps combined with gastrocnemius muscle flaps, one was repaired with femoral biceps muscle flap combined with gastrocnemius muscle flap, 13 were repaired with reverse anterolateral thigh island flaps, two were repaired with reverse anterolateral thigh island flap combined with gastrocnemius myocutaneous flaps, two were repaired with superior lateral genicular flaps, 4 were repaired with reverse posterior thigh island flaps, 11 were repaired with saphenous artery flaps. Patellar ligament was reconstructed in 4 patients. The tissue flap size ranged from 5 cm × 5 cm to 38 cm × 19 cm. Some donor sites were sutured directly, and the others were closed by split-thickness skin grafting obtained from ipsilateral or contralateral legs.

RESULTSAmong 59 tissue flaps of 54 patients, 55 tissue flaps of 50 patients survived, while necrosis of the distal part was observed in 4 tissue flaps, including one saphenous artery flap, two reverse anterolateral thigh island flaps, and one free latissimus dorsi myocutaneous flap. Among them, 3 flaps with necrosis at the distal part healed after debridement followed by skin grafting, one myocutaneous flap healed by transplanting gastrocnemius myocutaneous flap. During the follow-up period of 6 to 36 months, the tissue flaps were in good appearance and texture, and knee joint function was good in most cases. In 4 patients the knee joint function was satisfactory after patellar ligament reconstruction, while stiffness was observed in 4 out of 5 patients with knee joint injury.

CONCLUSIONSFree latissimus dorsi myocutaneous flaps are preferred to repair extensive defects around the knee joints. Reverse anterolateral thigh island flaps followed by saphenous artery flaps are preferred to repair wounds around the anterior knee. Wounds of the lateral knee are mainly repaired with reverse anterolateral thigh island flaps, and for small wounds the use of the superior lateral genicular flaps may be considered. Wounds of the medial knee can be repaired with modified sartorius myocutaneous flaps or saphenous artery flaps. Wounds of the posterior knee can be repaired with reverse posterior thigh island flaps or superior lateral genicular flaps. Wounds with severe infection or large space can be repaired with gastrocnemius myocutaneous flaps or muscle flaps or modified sartorius myocutaneous flaps. Anterolateral thigh flaps and gastrocnemius myocutaneous flaps are preferred in cases with indication of patellar ligament reconstruction.

This case demonstrates a rare variation in the pattern of injury and the presentation of acute lateral compartment syndrome of the leg. Although uncommon, lateral compartment syndrome of the leg after an ankle inversion leading to peroneus longus muscle rupture has been previously documented. This case was unusual because there was no overt ankle injury and the patient was able to continue physical activity, in spite of a significant rupture of the peroneus longus muscle that was determined later. This case highlights the necessary vigilance clinicians must maintain when assessing non-contact injuries in patients with possible compartment syndrome.

BACKGROUND: Several tendon graft and fixation methods have been introduced in medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar dislocation. The purpose of this study was to evaluate the results of MPFL reconstruction using a gracilis autograft fixation without bone tunnel in patients with recurrent patellar instability. METHODS: Nine patients (four males and five females) diagnosed with recurrent patellar instability from July 2009 to January 2013 and had MPFL reconstruction using a gracilis autograft were included. The average age of the patients was 24.6 years (range, 13 to 48 years), and the average follow-up period was 19.3 months (range, 12 to 30 months). For every patient, femoral attachment was fixed using suture anchors securing the patella by suturing the periosteum and surrounding soft tissue. Clinical evaluation included the Kujala, Lysholm, and Tegner scores; in addition, patients were examined for any complication including recurrent dislocation. The congruence angle and patella alta were assessed radiologically before and after surgery. RESULTS: The Kujala score improved from an average of 42.7 ± 8.4 before surgery to 79.6 ± 13.6 (p = 0.008) at final follow-up; the Lysholm score improved from 45.8 ± 5.7 to 82.0 ± 10.5 (p = 0.008); and the Tegner score improved from 2.8 ± 0.8 to 5.6 ± 1.5 (p = 0.007). The Insall-Salvati ratio changed from 1.16 ± 0.1 (range, 0.94 to 1.35) before surgery to 1.14 ± 0.1 (range, 0.96 to 1.29; p = 0.233) at the final follow-up without significance. The congruence angle significantly improved from 26.5°± 10.6° (range, 12° to 43°) before surgery to -4.0°± 4.3° (range, -12° to 5°; p = 0.008) at final follow-up. Subluxation was observed in one patient and hemarthrosis occurred in another patient 2 years after surgery, but these patients were asymptomatic. CONCLUSIONS: We achieved good results with a patellar fixation technique in MPFL reconstruction using a gracilis autograft employing soft tissue suturing in patients with recurrent patellar dislocation.

OBJECTIVETo investigate the morphological features of the perforator from the first plantar metatarsal artery, so as to provide anatomic basis for the reconstruction of soft-tissue defects of the forefoot.

METHODSThe first metatarsophalangeal joint was chosen as the landmark on 30 human cadaveric feet prefused with red latex. The following contents were observed under surgical magnifier: (1)The origin, courses,branches,distribution of the perforator of the first plantar metatarsal artery; (2)The anastomoses among the perforator of the first plantar metatarsal artery and other arteries on the medial aspect of the foot. Simulated operation was performed on one fresh specimen.

RESULTSThe perforator of the first plantar metatarsal artery passed through the space between the tendon, the abductor hallucis and the first metatarsal bone, and its entry point into the deep fascia was located (2. 3 ± 0.7 ) cm proximal to the first metatarsophalangeal joint. The perforator anastomosed with either the medial tarsal artery, the medial anterior malleolus artery or the branch of the medial plantar artery on the superior margin of the abductor hallucis, forming a longitudinal arterial chain,through which small branches were given off to the skin of the medial aspect of the foot. The perforator was( 1. 1 ± 0.2) mm in diameter and(3.2 ± 0.2) cm in length.

CONCLUSIONThe flap based on the perforator of the first plantar metatarsal artery can be harvested as an axial flap to repair the defects of soft tissue on the forefoot.
