Objective To evaluate the treatment and effects of wrist arthroscopy in tear of triangular fibrocartilage complex (TFCC). Methods Between January 2006 and December 2008, 16 patients with tear of TFCC were treated. Of 16 patients, 11 were male and 5 were female with an average age of 32.5 years (range, 25-51 years). Injury was caused by sprain in 12cases, and by fall ing in 4 cases. The locations were the left side in 10 cases and the right side in 6 cases. The mean injury duration was 3 months to 6 years and 2 months. The main cl inical symptoms included wrist powerlessness and ulnar-sided wrist pain which was aggravated with clench fist and l ifting heavy things. The results of the ulnar-sided wrist stress test were positive in 14 cases and negative in 2 cases. The preoperative values of wrist range of motion (ROM) were (45.58 ± 5.18)° at volar flexion, (41.22 ± 3.83)° at dorsal extension, (17.82 ± 2.48)° at radial deviation, (21.35 ± 4.61)° at ulnar deviation, (69.85 ± 8.36)° at pronation, and (70.13 ± 6.34)° at supination. According to Palmer standard, 10 cases of IA were treated with debridement; 3 cases of IB with suture and 1 of them failed and was partially excised; 2 cases of IC with debridment on triangular fibrocartilage disc, ulnolunate l igament, and ulnotriguetrum l igament; and 1 case of ID with trimming plastic operation. Results All incisions healed by first intention, and no compl ications of joint infection or neurovascular injury was found. All patients were followed up 14-38 months (mean, 18.5 months). Fifteen patients were restored to normal l ife and work without ulnar-sided wrist pain. One patient had no pain, but he had wrist powerless. The values of ROM at last follow-up were (50.16 ± 6.21)° at volar flexion, (45.37 ± 4.65)° at dorsal extension, (18.95 ± 3.56)° at radial deviation, (26.28 ± 5.09)° at ulnar deviation, (78.87 ± 7.69)° at pronation, and (76.46 ± 8.31)° at supination; showing significant differences when compared with preoperative values(P lt; 0.05). According to Green-O’Brien standard, the results were excellent in 9 cases, good in 6 cases, fair in 1 case, and the execellent and good rate was 93.75%. Conclusion The wrist arthroscopy not only can definitely diagnose tear of TFCC, but also is useful for treatment. In addition, the incision is small and the function is easy to recover, and the occurence of chronic ulnar-sided wrist pain can be effectively avoided.
Objective To explore the cl inical effectiveness of debridement in treatment of Pes anserinus bursitis under arthroscopy by comparing the curative effect of three therapies: local block therapy, open operation and debridement under arthroscopy. Methods From January 2000 to January 2007, 90 cases of unilateral Pes anserinus bursitis were treated with debridement under arthroscopy (group A, n=30), local block therapy (group B, n=30) and open operation (group C, n=30),respectively. The group A included 18 males and 12 females, aged (40.0 ± 2.5) years old; the locations were left knee in 16 cases and right knee in 14 cases; 10 cases had injury history, 7 cases had tired history and 13 cases had no obvious inducement; the course of disease was (24.0 ± 3.2) weeks. The group B included 17 males and 13 females, aged (37.0 ± 2.5) years old; the locations were left knee in 15 cases and right knee in 15 cases; 10 cases had injury history, 8 cases had tired history and 12 cases had no obvious inducement; the course of disease was (26.3 ± 3.5) weeks. The group C included 16 males and 14 females, aged (39.8 ± 2.2) years old; the locations were left knee in 18 cases and right knee in 12 cases; 8 cases had injury history, 10 cases had tired history and 12 cases had no obvious inducement; the course of disease was (25.0 ± 3.9) weeks. There was no statistically significant difference in the general data among three groups (P gt; 0.05). Results All patients were followed up 15 months on average (12-24 months). In group C, the inflammatory reation occurred at wound in 9 cases (30%) at 3-10 days after operation and was cured after symptomatic management; other incision healed by first intention; and showing statistically significant differences when compared with other 2 groups (P lt; 0.05). In group C, joint swell ing occurred at 1 week after operation in 1 case, l imitation of joint motion in 2 cases at 10-12 weeks after operation and was recovered after symptomatic management. In group B, 21 cases (70%) had a recurrence at 6-12 months after operation, all patients of other 2 groups had no recurrence; showing statistically significant differences between group B and groups A, C (P lt; 0.05). At last follow-up, the pain remain rates were 3.3% (group A), 0 (group B) and 33.3% (group C), and the compl ication incidence rates were 3.3%, 26.7% and 70.0%, respectively; all showing statistically significant differences among three groups (P lt; 0.05). At last follow-up, there were statistically significant differences in the visual analogue scale (VAS) score, the HSS score, and range of motion (ROM) between preoperation and postoperation in group A (P lt; 0.05); there was no statistically significant difference in the VAS score, HSS score and ROM between preoperation and postoperation in group B (P gt; 0.05); the ROM of postoperation in group C was smaller than that of preoperation (P lt; 0.05). There were statistically significant differences in the VAS score and HSS score between group A and groups B, C (P lt; 0.05), and in ROM among three groups after operation (P lt; 0.05). Conclusion The treatment of Pes anserinus bursitis with debridement under arthroscopy has advantages of easy-to-do, less compl ication, low relapse rate and good functional rehabil itation.

Methods: 12 cases of knee joint pigmented villonodular synovitis with the age of 18 to 46 years old were treated with arthroscopical synovectomy with a combined application of postoperative exercise and radiotherapy. The history of disease was 2 to 60 months, with the mean of 16 months. The clinical data were reviewed when followedup and evaluated by Lysholm score and and IKDC score. Results: 12 patients diagnosed by pathologic examination,including 8 localized and 4 diffused, were followed up for 3 to 21 months(13 months on average)with no relapses at the time of followup. Lysholm score was (62.3±2.4)points preoperatively, but (82.5±3.2) points 3 months later.The International Knee Documentation Committee (IKDC) score was (56.4±3.1) and (85.3±2.5) respectively before surgery and 3 months later. All patient remained good functions of knee joints except one who relapsed after open operation. Conclusion:In case of pigmented villonodular synovitis of the knee joint, arthroscopical synovectomy combined with postoperative radiotherapy and physical exercise is an effective treatment with less invasion and better function than open operation.
Objective To evaluate the results of arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, IIB, and IIIAB. Methods Sixteen patients with unilateral calcaneal fracture were treated with arthroscopically-assisted closed reduction and percutaneous screw fixation by posterior approach to subtalar joint between June 2012 and June 2015. There were 13 males and 3 females with an average age of 37.8 years (range, 18-65 years). The injury causes included falling from height in 10 cases and traffic accident in 6 cases. Of 16 cases, 4 were classified as Essex-Lopresti tongue type, 5 as Sanders IIA, 4 as Sanders IIB, and 3 as Sanders IIIAB. The interval of injury and operation was 4-8 days (mean, 5.94 days). The Böhler angle, Gissane angle, and width of calcaneus were measured before and after operation. American Orthopaedic Foot and Ankle Society (AOFAS) score was used to evaluate the ankle function at 12 months after operation. Results Primary healing of incision was obtained in all cases, and no complications of infection, necrosis, and osseous fascia compartment syndrome occurred. The patients were followed up 12-15 months (mean, 13.63 months). The X-ray films showed that fracture line disappeared at 6 months after operation; the patients had no tenderness or percussion pain, no breakage or loosening of internal fixation, no varus calcaneus tuberosity, no subtalar joint fusion, and no compression symptoms of peroneal tendons. Achilles tendon irritation occurred in 2 cases, and disappeared after removal of internal fixation; traumatic arthritis occurred in 2 cases, and was relieved after removal of internal fixation. The Böhler angle, Gissane angle, and calcaneal width were significantly improved at 3 days and 6 months after operation when compared with preoperative ones (P<0.05). The loss of the above indexes was observed at 6 months, showing no significant difference between at 3 days and 6 months (P>0.05). The AOFAS score results were excellent in 11 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 87.5%. Conclusion It has the advantages of little trauma, less complication, and good function recovery to use arthroscopically-assited closed reduction and percutaneous screw fixation by posterior approach to subtalar joint for calcaneal fractures of Essex-Lopresti tongue type, Sanders IIA, Sanders IIB, and Sanders IIIAB.
Objective To evaluate the effectiveness of arthroscopic debridement and release for post-traumatic arthritis of subtalar joint. Methods Between January 2011 and December 2014, 14 cases of post-traumatic arthritis of the subtalar joint underwent arthroscopic debridement and release, and the clinical data were retrospectively analyzed. All patients were male, aged 42 years on average (range, 32-62 years). Calcaneus fracture was caused by falling from height; 8 cases received conservative treatment and the other 6 cases received open reduction and internal fixation. The mean interval from injury to operation was 3.4 years (range, 2-7 years). The arthroscopic debridement and release were performed through lateral portals. The injury degree of articular cartilage was classified as grade 3 in 4 cases and grade 4 in 10 cases based on Outerbridge rating. The degree of pain was assessed by visual analogue scale (VAS) and the function of joint was assessed by the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle Hindfoot Scale. Results All incisions healed by first intention and no complication occurred. The follow-up time was 18 months. Pain was relieved obviously; VAS was significantly decreased to postoperative 3.8±0.9 at 18 months from preoperative 7.7±1.2 (t=9.728,P=0.000), and AOFAS Ankle Hindfoot Scale was significantly increased to postoperative 59.1±8.8 from preoperative 37.6±8.2 (t=6.688,P=0.000). During follow-up, no patient was given arthrodesis and no worsened sign was found on the postoperative CT and MRI. Conclusion Arthroscopic debridement and release for post-traumatic arthritis of the subtalar joint can relieve clinical symptoms and delay subtalar arthrodesis.
Objective To investigate the medium-term clinical outcome of encircled suture for repair of medial meniscus bucket-handle tear (BHT). Methods Between March 2011 and June 2013, 78 patients (78 knees) with medial meniscus BHT were treated with encircled suture under arthroscopy. There were 57 males and 21 females with a mean age of 28.3 years (range, 16-39 years). The causes included sports injury in 61 cases, traffic accident injury in 12 cases, and other trauma in 5 cases. Of 78 cases, 35 were acute injury and 43 were chronic injury; 65 cases had combined injury of anterior cruciate ligament rupture. International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were 48.2±6.3, 43.6±4.7, and 2.5±0.6, respectively. Barrett’s assessment standard, MRI, and arthroscopy examination were used for assessment of meniscus healing. IKDC score, Lysholm score, and Tegner score were used for assessment of knee function. Results Primary healing of incisions were achieved in all patients, and no complications occurred. All patients were followed up 26-63 months (mean, 42.8 months). BHT recurrence was observed in 2 patients within 1 year. Clinical healing of meniscus tear was obtained in 72 cases (92.3%) according to Barrett’s assessment standard. The IKDC score, Lysholm score, and Tegner score were significantly improved to 81.5±5.1, 86.9±3.9, and 6.2±0.5 respectively (t=–14.598,P=0.000;t=–18.478,P=0.000;t=–3.362,P=0.002). MRI results showed complete healing in 56 cases, incomplete healing in 15 cases, and unhealing in 7 cases at last follow-up, with a total healing rate of 91.0% (71/78) and a complete healing rate of 71.8% (56/78). In 21 cases undergoing arthroscopy at 18-49 months after operation, complete healing and incomplete healing were observed in 17 cases and 4 cases respectively, with a total healing rate of 100% (21/21) and a complete healing rate of 81.0% (17/21). No re-tear occurred. Conclusion Encircled suture for repair of medial meniscus BHT owns the advantage of firm suturing and good blood supply which can obtain satisfactory medium-term clinical results.
Objective To investigate the clinical outcomes of autologous platelet rich plasma (PRP) for anterior cruciate ligament (ACL) reconstruction. Methods Between August 2014 and August 2016, 42 patients with ACL ruptures who underwent arthroscopic ACL reconstruction were randomly divided into 2 groups: 21 patients received graft soaked with PRP (trial group) and 21 patients received routine graft in ACL reconstruction (control group). Because 6 patients failed to be followed up, 17 patients of trial group and 19 of control group were enrolled in the study. There was no significant difference in gender, age, body mass index, side, injury reason, disease duration, Kellgren-Lawrence grade, and preoperative visual analogue scale (VAS), Lysholm score, and International Knee Documentation Committee (IKDC) activity scores between 2 groups (P>0.05). VAS score, Lysholm score, and IKDC activity scores were used to evaluate pain and function at 3 and 12 months postoperatively. Further, second arthroscopy and MRI examination were performed at 12 months postoperatively. Results The patients in both groups were followed up 3 to 12 months with an average of 9.83 months. The VAS score, Lysholm score, and IKDC activity scores were significantly improved at 3 and 12 months after operation in 2 groups (P<0.05), and the scores of trial group were significantly better than those of control group at 3 months (P<0.05), but no significant difference was found between 2 groups at 12 months (P>0.05). No complications of effusion, infection, and allergy were observed in 2 groups during follow-up. MRI showed good position of ACL grafts and good signal quality of the graft in the majority of the cases. However, mixed hyperintense and presence of synovial fluid at the femoral bone-tendon graft interface were found in 3 patients of trial group and 4 patients of control group, indicating poor remodeling ligamentation. MRI score was 3.53±1.13 in trial group and was 3.21±0.92 in control group, showing no significant difference (t=0.936,P=0.356). The second arthroscopy examination showed ligament remodeling score was higher in trial group than control group (t=3.248,P=0.014), but no significant difference was found in synovial coverage score and the incidence of cartilage repair (t=2.190,P=0.064;χ2=0.090,P=0.764). Conclusion PRP application in allograft ACL reconstruction can improve knee function and relieve pain after operation, which may also accelerate graft remodeling.
Objective To investigate the short-term effectiveness of joint distraction by Ilizarov combined with arthroscopic debridement in the treatment of knee osteoarthritis (KOA). Methods Between January 2014 and January 2015, 15 patients (15 knees) with KOA were treated using arthroscopic debridement assisting with the Ilizarov distraction technology. There were 7 males and 8 females, aged from 45 to 64 years (mean, 55 years). The left knee and the right knee were involved in 6 and 9 cases respectively. The disease duration was 2.0-9.5 years (median, 6 years). They all had received conservative treatment for 6 months and got poor clinical improvement. The preoperative visual analogue scale (VAS) score, the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score, the knee injury and osteoarthritis outcome score (KOOS), the range of motion (ROM) for knee, and the radiographic joint space width were 76.2±8.8, 59.3±5.7, 44.3±7.2, (75±21)°, and (2.5±0.4) mm respectively. According to Kellgren-Lawrence grade system, 11 cases were rated as grade III and 4 cases as grade IV. Results There was no poor incision healing, infection, and deep vein thrombosis. All the 15 patients were followed up 12-18 months (mean, 15.5 months). Patients achieved pain relief. The knee activity was obviously improved. The postoperative VAS score, WOMAC score, KOOS score, and ROM at 12 months were 20.9±7.8, 38.2±5.5, 92.1±6.9, and (118±14)° respectively, showing significant difference when compared with preoperative ones (t=18.213, P=0.000; t=10.317, P=0.000; t=18.564, P=0.000; t=6.599, P=0.000). Postoperative X-ray film showed that joint space width at 12 months was (3.8±0.3) mm, showing significant difference when compared with preoperative one (t=10.070, P=0.000). Conclusion Joint distraction by Ilizarov combined with arthroscopic debridement can effectively relieve pain, improve the function and quality of life. It was beneficial to cartilaginous tissue repair and delaying the degenerative process of KOA. The short-term effectiveness is satisfactory.
Objective To assess the effectiveness of arthroscopic capsular release to treat primary severe frozen shoulder through trans cuff portal. Methods Between June 2012 and January 2015, 28 patients with primary severe frozen shoulder were enrolled in the study. There were 8 males and 20 females with an average age of 57 years (range, 42-81 years). The left shoulder was involved in 16 cases and the right one in 12 cases. The mean disease duration was 11 months (range, 7-21 months). Six patients had diabetes. All patients underwent arthroscopic capsular release by trans cuff portal. The range of motion (ROM) of the shoulder were measured at preoperation and at 6 weeks and 24 months after operation; the scores of American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) were used to evaluate the shoulder function and pain. Results Primary healing of incision was obtained, and no complications of infection, shoulder instability, and nerve injury were found. All patients were followed up 24 months. Pain of the shoulder was obviously relieved; VAS score was significantly lower at 6 weeks and 24 months after operation than preoperation (P<0.05), and at 24 months than 6 weeks (P<0.05). ROM of the shoulder and ASES score at 6 weeks and 24 months after operation were significantly increased when compared with preoperative ones (P<0.05); significant difference was found in ROM of forward flexion and external rotation and the ASES score between at 6 weeks and 24 months (P<0.05). And internal rotation in-creased from trochanter (9 cases), hip (6 cases), sacrum (7 cases), and L4 vertebral level (6 cases) before operation to the T12-T6 vertebral level at 6 weeks and 24 months after operation, which were close to normal side. Conclusion Arthroscopic capsular release through trans cuff portal is an effective and safe management for primary severe frozen shoulder.
Objective To evaluate the effectiveness of arthroscopy for synovial chondromatosis of hip joint. Methods Between April 2012 and September 2015, 32 patients with synovial chondromatosis of hip joint were treated by arthroscopy. There were 19 males and 13 females, with an average age of 42.1 years (range, 22-64 years). The synovial chondromatosis located at right hip in 15 cases and left hip in 17 cases. The main clinical symptoms were pain and swelling of hip joint. Of all patients, 6 cases were hip hinge, 2 cases were lower limb weakness, and 1 case was snapping hip. The " 4” sign was positive in 9 cases, Thomas’ sign positive in 4 cases, and rolling test positive in 2 cases. Results All incisions healed by first intention, and no complication occurred. All patients were followed up 16-48 months (mean, 33.8 months). The visual analogue scale (VAS) was 1.4±0.8 at last follow-up, which was significantly lower than that before operation (4.8±1.2) (t=6.382, P=0.013). The hip Harris score was 92.6±6.7 at last follow-up, which was significantly higher than that before operation (63.2±8.3) (t=9.761, P=0.006). At last follow-up, the " 4” sign and Thomas’ sign were positive in 3 cases and 1 case, respectively. The others had no positive sign. X-ray film showed no recrudescence in all cases. Conclusion Treating synovial chondromatosis of hip joint under arthroscopy has advantages of less trauma, complete debridement, quick postoperative recovery, and the satisfactory short-term effectiveness.
