Between March 1992 and December 1995 at St. Paul's, Holy Family, St. Vincent and Eui Jung Bu St. Mary Hospitals Catholic University, two hundred and eighty patients underwent arthroscopic anterior cruciate ligament(ACL) reconstruction using central one-third bone-patellar tendon-bone autograft. Nine of these patients had limitation of motion(LOM) defined as a knee flexion contracture greater than 10o or less than 125o of passive knee flexion. This study analyzes the causes of LOM after ACL reconstruction as well as the results after passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM. The results are as follows: 1. Out of nine patients, initially three had isolated ACL injuries and six had combined injuries. Seven of nine cases were perfomed by ACL reconstruction within four weeks and two were performed after four weeks following injury. 2. Treatment for LOM after ACL reconstruction was done after 5.5 months on average. 3. Arthroscopic adhesiolysis was done in 5 cases. There were fibrous adhesions at suprapatellar pouch and femoral intercondylar notch in all cases, respectively, infrapatellar fat pad in 3 cases and medial para patellar gutter in 2 cases. Two patients had a fibrous nodule, "cyclops" lesion, which formed anterior to the ACL graft. 4. Range of motion and Lysholm knee score were much improved following passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM.

Peripheral nerve injuries in the oral and maxillofacial regions require nerve repairs for the recovery of sensory and/or motor functions. Primary indications for the peripheral nerve grafts are injuries or continuity defects due to trauma, pathologic conditions, ablation surgery, or other diseases, that cannot regain normal functions without surgical interventions, including microneurosurgery. For the autogenous nerve graft, sural nerve and greater auricular nerve are the most common donor nerves in the oral and maxillofacial regions. The sural nerve has been widely used for this purpose, due to the ease of harvest, available nerve graft up to 30 to 40 cm in length, high fascicular density, a width of 1.5 to 3.0 mm, which is similar to that of the trigeminal nerve, and minimal branching and donor sity morbidity. Many different surgical techniques have been designed for the sural nerve harvesting, such as a single longitudinal incision, multiple stair-step incisions, use of nerve extractor or tendon stripper, and endoscopic approach. For a better understanding of the sural nerve graft and in avoiding of uneventful complications during these procedures as an oral and maxillofacial surgeon, the related surgical anatomies with their harvesting tips are summarized in this review article.

Purpose: To report the clinical results of patients treated for a rupture of the distal tendon of biceps brachii Materials and Methods: Between February 1987 and March 2004, we treated 16 patients with a rupture of the distal tendon of biceps brachii. 9 of 16 patients underwent surgical treatment. All cases were male, median age was 26.3(range, 16-48) years. The mean interval between injury and surgery was 4.7 days (range, 1~36 days). Operative correction was performed anatomically, using the two-incision technique(3 cases) or one-incision technique(6 cases). Clinical outcomes were evaluated one year after operation by assessing the review about the physical examination finding and radiologic findings with surgical findings, range of motion, muscle strength, subjective satisfaction, activity and return to previous occupation. and via telephone interview in cases of conservative treatment. Results: In cases of surgical treatment, 85.8%, 86.3% of flexion-extension and supination-pronation motion than healthy side were measured respectively. 75% of flexion power than healthy side was measured. Eight of nine(89%) were very satisfied. Eightl of nine returned to original job. In cases of conservative treatment, 65% of flexion power than pre-injury state was reported. Four of seven were satisfied, two were dissatisfied, one was very dissatisfied. Three of seven returned to original job. Conclusion: Early anatomic reconstruction can restore more strength and endurance for supination and flexion range and power. Conservative management may be considered for partial injuries, but operative repair must be considered in complete rupture, athletes, patient with high activity.

Purpose: This study was based on the Korean Foot and Ankle Society (KFAS) member survey and aimed to report the current trends in the epidemiology, diagnosis, and management of acute Achilles tendon rupture (AATR) over the past few decades. Materials and Methods: A web-based questionnaire containing 34 questions was sent to all KFAS members in October 2021. The questions were mainly related to the clinical experience and preferred management of patients with AATR. Answers with a prevalence ≥50% of the respondents were considered a tendency. Results: Seventy-one (12.9%) of the 550 members responded to the survey. The male sex ratio in AATR was answered mean 78%, and the most common age groups were 30~40 years (n=49; 69.0%), and 40~50 years (n=37; 52.1%), in that order. The most common seasons for the occurrence of AATR were spring (37 cases; 52.1%) and autumn (27 cases; 38.0%). Also, sports-related rupture had an average occurrence of 76.2%. The most important clinical factor to determine the type of treatment was the history of previous injuries, and 75.9% of respondents started conservative treatment in the 2010s. The most preferred protocol of conservative treatment was an orthosis capable of ankle range of motion after casting (68.5%), and 53.7% 'satisfied' and 1.9% 'very satisfied' with conservative treatment. The most preferred surgical method was open repair (80.3%), and the Krackow method (60.6%), and 49.3% of treated patients responded 'satisfied' and 45.1% 'very satisfied' with this treatment. Conclusion: This study gives updated information concerning the current trend of epidemiology, diagnosis, and treatment of AATR in Korea. Both consensus and variation in the approach to AATR were identified using this survey study. This study may raise the awareness of various possible approaches toward AATR and should be used to further establish a standard protocol for the management of this injury.

In both cosmetic and functional aspects, loss of digital pulp is a common problem. Compound or composite defects of the hand and fingers with exposed denuded tendon, bone, joint, or neurovascular structures may require flap coverage. Most often these lesions can be repaired by using simple local flap, neurovascular flap, thenar flap, and cross-finger flap. But microvascular reconstruction is sometimes needed for large defects. But Authors do not recommend these procedures in case of severe crushing injuries involving multiple finger pulp losses because they have possibility of damage of the vascular network and infection. So we applied distant flaps such as chest flaps, groin flaps, abdominal flaps and etc. And then we applied surgical rubber gloves for remodeling the flap after cutaneous healing. We have acquired satisfactory results, after the simple molding method for distant flap finger by using surgical rubber gloves treatment.

Prolotherapy, the technology for strengthening lax ligaments, has found increased acceptance in recent years. Prolotherapy involves the injection of the irritant solutions into the weakened or stretched ligaments which are a source of chronic pain. This induces an inflammatory response which mimics the normal repair sequence. Various musculoskeletal disorders of lower extremities such as degenerative arthrtitis, ligament and tendon injuries can be treated with prolotherapy. Prolotherapy is a very good, powerful nonsurgical conservative treatment in various musculoskeletal disorders. Ultrasound exam is very useful to find and confirm the exact location of disorders and check the progress in prolotherapy practices.

This study is to report the effectivenes of Meridian-Test (M-test) in 2 cases on shoulder diseases. The M-test was applied to one patient diagnosed with as impingement syndrome and one patient diagnosed with tear of supraspinatus tendon. The changes in numeral rating scale and range of motion were identified to assess the progress of the treatment. After three times treatments, In example 1, the pain decreased from 6 to 0.5 and the range of flexion and abduction increased from $150^{\circ}$ to $180^{\circ}$. In example 2, the pain decreased from 6.5 to 1, and the range of shoulder flexion increased from $120^{\circ}$ to $170^{\circ}$, while the range of abduction increased from $90^{\circ}$ to $170^{\circ}$. Based on the above results, it would be effective to apply M-test to treat shoulder diseases in these two cases.

Patellofemoral instability (PFI) is common in pediatric knee injuries. PFI results from loss of balance in the dynamic relationship of the patella in the femoral trochlear groove. Patellar lateral dislocation, which is at the extreme of the PFI, results from medial stabilizer injury and leads to the patella hitting the lateral femoral condyle. Multiple contributing factors to PFI have been described, including anatomical variants and altered biomechanics. Femoral condyle dysplasia is a major risk factor for PFI. Medial stabilizer injury contributes to PFI by creating an imbalance in dynamic vectors of the patella. Increased Q angle, femoral anteversion, and lateral insertion of the patellar tendon are additional contributing factors that affect dynamic vectors on the patella. An imbalance in the dynamics results in patellofemoral malalignment, which can be recognized by the presence of patella alta, patellar lateral tilt, and lateral subluxation. Dynamic cross-sectional images are useful for in vivo tracking of the patella in patients with PFI. Therapeutic approaches aim to restore normal patellofemoral dynamics and prevent persistent PFI. In this article, the imaging findings of PFI, including risk factors and characteristic findings of acute lateral patellar dislocation, are reviewed. Non-surgical and surgical approaches to PFI in pediatric patients are discussed.

Peripheral nerve injury occurs mostly by trauma and is usually associated with fracture of bone and joint, muscular injury and tendon injury and it also evokes paralysis and anesthesia. When treatment of peripheral nerve injury is considered,, the modality of treatment is decided by the general condition of the patient, type of injury, associated injuries and the condition of wound. To get the maximum results, surgical treatment and reconstruction and rehabilitation should all go in hand-in-hand. From January 1985 to December 1994, we observed 61 patients that had operation without reconstruction due to peripheral nerve injury with a follow-up period of more than 1 year. Among the 61 patients, 44 were men(72%) and 17 were women(28%). Follow-up period was average 19 months. Age distribution was mostly in their twenties with a mean age of 28 years. Time interval of operation after injury was average 11 months. Trauma was the main cause of peripheral nerve injuries with a proportion of 87%. 31 patients had neurorrhaphy, in which case 14 patients had stay suture and 17 patients did not. 14 patients had nerve graft, and 16 patients had neurolysis. We used our scales to compare the results of surgery on the basis of British Research Council System. We gave scores to every sensory and motor scale to estimate functional improvement and emphasized on motor functional improvement. The total score = sensory score + ($2{\times}motor$ score). We considered 8-9 points as excellent, 6-7 points as good, 2-5 points as fair, 0-1 points as poor result. We considered excellent and good as much improved. Excellent and good results were obtained in 13 out of 14 neurorrhaphy with stay suture(93%), 12 out of 17 neurorrhaphy without stay suture(71%), 6 out of 14 nerve graft(43%), 12 out of 16 neurolysis(75%). Among the patients with neurorrhaphy done within 3 months, 11 out of 14(86%) showed improvement, but among the patients after 4 months 3 out of 17(76%) showed improvement. 84% of improvement was observed in the patients with time interval from injury to surgery within 3 months, and 64% in the patients with time interval after 4 months. In the aspect of age, 77% with the age below 20 years, 70% with the age between 21 and 30 years, 66% with the age above 31 years showed improvement. We conclude that considering degree of injury, time interval from injury and age with the adequate method of treatment, we can obtain good results from surgery.

Purpose: To evaluate the overall results and its major affecting factors(athlete/associated injury) of modified Brostrom procedure for chronic ankle lateral instability. Materials and Methods: Fifty-one patients (51 ankles) with chronic ankle lateral instability were sub-grouped athletes and non-athletes and again sub-grouped with associated injury and without associated injury. Associated injuries were osteochondral defect(6), peroneal tendon abnormality(10), os subfibularae(4), os subtibialae(4), anterior impingement(5) and loose body(2). The overall surgical results were evaluated and also see whether or not athletes and associated injury affect the result. Result: Of the 51 operations performed, there were 39 excellent, 8 good and 4 fair as a whole. Of the 24 athletes operated, there were 19 excellent, 3 good, and 2 fair. Among the 27 non-athletes, there were 20 excellent, 5 good and 2 fair results. The average time to ordinary life in the non-athlete group was 2.5 months and average time to sports activity in the athlete was 4.5 months postoperatively. Those who didn't have any associated injury had all excellent result, on the contrary, those who had associated injuries, 14 excellent, 8 good and 4 fair results. All the fair results were associated with osteochondral lesion of talus. Whether or not the patient is athlete does not affect the surgical results, but whether or not there were associated injuries does affect the surgical results. Conclusion: Modified Brostrom procedure for chronic ankle lateral instability itself is an excellent to good operation. This procedure can be used in athletic populations who need high demand of sports activity. But chronic ankle lateral instability with associated injury group showed variable, less satisfactory results than those without associated injury. Careful preoperative and intraoperative examination should be done to find out the associated injury with chronic ankle lateral instability.
