RESUMO
<p><b>OBJECTIVE</b>To investigate surgical procedure and clinical effects for the treatment of patellofemoral osteoarthritis (PFOA) with arthroscopic patelloplasty and circumpatellar denervation.</p><p><b>METHODS</b>Totally 156 patients with PFOA (62 males and 94 females; aged from 45 to 61 years old with an average of 52) were treated from September 2011 and March 2013. The clinical manifestations included recurrent swelling and pains on knee-joint,and aggravated pains upon going up/down-stairs, squatting-down, or standing-up. PFOAs were treated with arthroscopic patelloplasty and circumpatellar denervation. The therapeutic effects before and after surgery were evaluated by Lysholm scores and Kujala scores. The therapeutic effects were graded by classification of cartilage injury degrees.</p><p><b>RESULTS</b>Totally 149 cases were successfully followed up for 14.8 months. The incisions were healed well and no complication were occurred. Lysholm score was improved from 73.29 preoperatively to 80.93 postoperatively and average Kajala score from 68.34 preoperatively to 76.48 after surgery. This procedure was highly effective for patients with I - III degree cartilage injury, while not for patients with IV degree cartilage injury.</p><p><b>CONCLUSION</b>For PFOA patients, arthroscopic patelloplasty and circumpatellar denervation is effective for significantly relieving anterior knee pains, improving knee-joint functions and quality of life, and deferring arthritic procession.</p>

<p><b>OBJECTIVE</b>To explore the effectiveness of hamstring tendon graft embedding reconstruction of medial patellofemoral ligament for the treatment of recurrent dislocation of the patella.</p><p><b>METHODS</b>From March 2008 to June 2013,67 patients with recurrent dislocation of patella were treated, including 28 males, 39 females with an average age of 22 years ranging from 10 to 42 years old. The clinical manifestations involved knee joint instability,"giving way", sense of patellar dislocation, anterior knee pain. All 67 patients underwent arthroscopic hamstring tendon graft embedding reconstruction of the medial patellofemoral ligament. The curative effect were evaluated by preoperative and postoperative Lysholm score and Q angle changes.</p><p><b>RESULTS</b>All cases were followed up after operation and the mean follow-up time was(27.5±13.4) months(4 to 69 months). Postoperative incision were healed well and no patellar dislocation or subluxation occurred. Lysholm score improved from preoperative 76.35±2.86 to 82.71±2.29 postoperatively; Q angle decreased from preoperative (18.75±2.33)° to postoperative(13.28±1.75)°.</p><p><b>CONCLUSION</b>The method for the reconstruction of medial patellofemoral ligament can provide enough tension, patellar stability.imoroving the function of knee ioint.</p>

<p><b>OBJECTIVE</b>To explore causes of gluteal muscle contracture induced anterior knee pain and curative effect of arthroscopic release.</p><p><b>METHODS</b>From March 2002 to August 2013,36 patients with gluteal muscle contracture induced anterior knee pain were treated, including 15 males, 21 females, aged from 9 to 40 years old with an average (18.7±7.2) years old; the courses of diseases ranged from 4 to 30 years. The clinical manifestations involved limited to symmelia, positive Ober sign, buttocks touch contracture belts, knee and patella slide to lateral when doing squat activities. All patients were performed gluteal muscle contracture release under arthroscopic. Postoperative complications were observed, Kujala scoring before and after operation was used for compare curative effect.</p><p><b>RESULTS</b>All patients were followed up with an average of 29 months. The incision were healed well, and no complications were occurred. Postoperative Kujala score were improved more than preoperative.</p><p><b>CONCLUSION</b>Gluteal muscle contracture release could alleviate hypertension of lateral patella, and palys an important role in preventing patellofemoral arthritis.</p>

<p><b>OBJECTIVE</b>To evaluate the clinical outcome of arthroscopic repair method of meniscus injury with Fast-fix under local anesthesia.</p><p><b>METHODS</b>From October 2005 to September 2012,106 patients with meniscus injuries admitted into our - hospital were studied, including 74 males and 32 females, ranging in age from 13 to 71 years old, averaged 27.6 years old. The duration of the disease ranged from 15 days to 5 years. The main clinical manifestations included knee joint pain after exercise, joint locking, pressing pain of knee joint and positive McMurray signs. The MRI showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-fix under local anesthesia. Each patient was assessed with VAS pain evaluation and Lysholm knee-joint score system before and after operation. All the patients were followed up more than 1 year.</p><p><b>RESULTS</b>One hundred and 2 patients were followed up by recording subjective symptoms, clinical examinations and questions naires for an average of 2.6 years (ranged, 1.1 to 8 years), and 4 patients lost follow-up. All the 102 patients had no anesthetic complications. Ninety-six patients had normal subjective symptom and clinical examinations. Four patients had a mild ache with activities,2 patients had moderate pain after activities with joint space pressing pain. VAS pain evaluation and Lysholm knee-joint score after operation both were much better than that before operation.</p><p><b>CONCLUSION</b>onclusion: Local anesthesia can provide nice circumstances for surgeries. Arthroscopic repair using Fast-fix is an idea method for meniscus injury, especially for the posterior horn tear of medial meniscus, which is simple and convenient with less complications, and satisfactory results.</p>

<p><b>BACKGROUND</b>Double plate osteosynthesis is the standard treatment for intra-articular fractures of the distal humerus. However, there is still controversy concerning dual plate positions in terms of providing optimal stability. The purpose of this retrospective study was to compare the clinical outcomes in patients with type C intra-articular distal humeral fractures using perpendicular and parallel plating methods.</p><p><b>METHODS</b>Between March 2008 and June 2011, a total of 45 patients with type C distal humerus fractures were treated using two different dual plating methods. Of them, 24 patients were treated by perpendicular plating (group I) and 21 patients were treated by parallel plating (group II). The surgical time, blood loss, and union time were compared between the two groups. The flexion-extension arc, the total range of flexion and extension at the end of follow-up were compared between the two groups. The Mayo Elbow Performance Score (MEPS) was used to determine the elbow functional results.</p><p><b>RESULTS</b>All patients were followed up. The mean duration of follow-up was 16 months (range 12 - 25 months) in group I and 15.5 months in group II (range 12 - 25 months). There were no significant differences in the surgical time, blood loss, and the bone union time between the two groups. In group I, the mean elbow flexion-extension arc was 101° and the mean MEPS was 85 points. The rate of excellent and good results was 87.5%. In group II, the mean flexion-extension arc was 100° and the mean MEPS was 86.1 points. The rate of excellent and good results was 90.5%. There were no significant differences in the MEPS, flexion-extension arc, and the total range of flexion and extension between the two groups.</p><p><b>CONCLUSIONS</b>Perpendicular and parallel plate configurations with the appropriate surgical techniques can provide anatomical reconstruction and stable fixation of type C intra-articular distal humeral fractures and allow early mobilization of the elbow after an operation. The occurrence of post-operative elbow stiffness can be reduced and good outcomes can be obtained.</p>
