Giant cell tumors are primary bone tumors originating from non-osteoblastic connective tissue. The sites of involvement were commonly distal femur, proximal tibia, proximal humerus, distal radius and others (including os calcis, ilium and sacrum). Giant cell tumor located around knee joint has been difficult to treat because of local recurrence following curettage with or without bone graft. Although primary resections reduce recurrence of the lesion, the joint function will be markedly impaired. Marginal excision was very often complicated by a loss of joint integrity since all the giant cell tumors occupy juxtaarticular positions. Techniques involving physical adjuncts(high speed burr and electric cauterization) have been used in the hope of decreasing the rate of local recurrence and avoiding the morbidity of primary resection. A meticulous clinical, radiological and histological evaluation is needed to choose the correct treatment, keeping in mind the possibility of recurrence after each treatment modality.

Giant cell tumor is most frequently found in juxtaarticular region, and difficult to treat because of local recurrence. Although primary resections reduce recurrence, the joint function will be markedly impaired. Techniques involving physical adjuncts(high speed burr and electric cauterization), acrylic cement or en bloc resection with VFG(vascularized fibular graft) have been employed to reduce local recurrence. From October 1984 to April 1994, twenty-nine patients diagnosed as giant cell tumor were treated at department of Orthopaedic Surgery, School of Medicine, Kyung Hee University. There were eleven men and 18 women, ranging in age from 17 to 52 years(mean: 34 years). The average follow-up period was four years and five months. The location of the lesion was around the knee in 15, distal radius in three, femoral head in three, and others in eight patients. Fifteen patients around the knee joint were treated with several modalities; curettage with bone graft in five, curettage with cement filling in three, curettage with bone graft and physical adjuncts in five, en bloc resection with VFG in one and en bloc resection with arthroplasty in one patient. The functional results, according to the Marshall's knee score, were excellent in one, good in two, and fair in two after the curettage with bone graft, good in three after the curettage with bone cement filling, excellent in one, good in four after the curettage with bone graft and physical adjuncts, and good in two after the en bloc resection with VFG or arthroplasty. Three patients had local recurrence among 15 patients with giant cell tumor around knee. Vascularized fibular graft around wrist joint provided good functional restoration without local recurrence in all three patients who had giant cell tumor in distal radius. Although there is no statistical significance, it seems that curettage with bone graft using physical adjuncts or acrylic cement reveals better results than simple curettage with bone graft. Excellent functional result were obtained without local recurrence by using vascularized fibular graft after en bloc resection.

Objective: To compare the therapeutic efficacy of the bone marrow aspirate concentrate (BMAC)- platelet-rich plasma (PRP) complex with hyaluronic acid in patients with knee osteoarthritis. Method: Thirty-four patients with knee osteoarthritis participated in this study. Seventeen patients in the study group underwent BMAC and PRP extraction followed by intra-articular injection of BMAC-PRP complex within affected knee. Seventeen patients in the control group underwent intra-articular injection of hyaluronic acid. Knee injury, osteoarthritic outcome score (KOOS), and EuroQol-5D (EQ-5D) questionnaire were evaluated before, one month, three months, and six months after the injection. Results: There were statistically significant temporal differences in total KOOS scores in both BMAC-PRP and HA groups. However, there were no significant group difference in the study period. In the Sports and Recreational Function Scale, there was statistically significant improvement in the BMAC-PRP group compared to the HA group at three months (p=0.041). There were no side effects or complications in both groups. Conclusion: Intra-articular injection of BMAC-PRP showed better functional recovery in the OA at three months and this can be an alternative treatment in terms of functional recovery in the OA in addition to the decrease of pain.

Osteoarthritis(degenerative joint disease), the most common arthropathy affecting the aged people, is characterized by degeneration of articular cartilage with proliferation and remodeling of subchondral bone. Osteoarthritis of the knee, which probably has greater social cost and more associated disability than osteoarthritis of any other joint, prevalence is known to increase with age, and females have higher rates than males; radiographic abnormalities are present in more than 30% of persons more than 65 years old, with approximately 40% of these persons symptomatic. Though the etiology of osteoarthritis is not entirely understood, much information is available regarding risk factors for the development of knee osteoarthritis that permit some reasonable guideline for preventive strategies. Traumatic damage or occupational or recreational overuse of knee joint may result in osteoarthritis, and obesity also is related to osteoarthritis of the knee. A variety of other possible risk factors for the development of knee osteoarthritis have been proposed, including increased bone mass, smoking, diseases such as diabetes or elevated serum uric acid, and some metabolic factors, but the contribustions of these and other factors such as smoking or race and diseases such as diabetes are as yet undetermined. The usual clinical manifestations include pain, stiffnesss, crepitus and loss of function. In oriental medicine, osteoarthritis of the knee is very similar to diseases such as Bijung(痺症), Haksulpung(鶴膝風), Youkjeolpung(歷節風) in symptoms. The diseases such as Bijung(痺症), Haksuipung(鶴膝風), Youkjeolpung(歷節風) is related to the of function liver(肝) and kidney(腎) and risk factors are regarded as Pung(風), Han(寒), sub(濕). The diagnosis of osteoarthritis of the knee has often been based on radiographic appearance and clinical manifestations. The acupuncture therapy of osteoarthritis of the knee has often been based on Stomach meridian(ST), Spleen meridian(SP), Kidney meridian(KI), Liver meridian(LR).

In this study, we performed the compressive strength test of trabecular bone in knee joint for measuring the elastic modulus and ultimate strength. The main knee joint is femorotibial articulation between the lateral and medial femorotibial condyle. In the case of osteoarthritis, some patients have only medial condylar osteoarthritis. We performed the mechanical test for comparison the difference of the each condylar strength. We used diamond core-drill and linear precision saw for making the specimens. Specimens were cored from both condyle in distal femur and proximal tibia in fresh cadaver (male 10, female 12), and tested by universal test machine with temperature control saline circulation system. Results of the test in distal femoral parts, averaged elastic modulus was $360.61{\pm}159.40MPa$ for male, $150.89{\pm}70.65MPa$ for female. Averaged ultimate strength was $6.79{\pm}2.91MPa$ for male, $2.89{\pm}1.31MPa$ for female. Male was 2.4 times stronger than female. In the proximal tibial parts, averaged elastic modulus was $108.80{\pm}52.88MPa$ for male, $73.45{\pm}55.06MPa$ for female. Averaged ultimate strength was $2.59{\pm}1.39MPa$ for male, $1.75{\pm}1.16MPa$ for female. Male was 1.5 times stronger than female. In the distal femoral condyle, medial condyle had more strength than lateral condyle at middle region. But lateral condyle had more strength than medial condyle at anterior & posterior regions (p<0.02). In the proximal tibial condyle, medial condyle had more strength than lateral condyle. (p<0.01).

Purpose: The strength of hand grip, low back muscles and knee joint muscles were measured and then compared to the bone mineral density (BMD) of each forearm bones (including ulna and radius), lumbar spine, and femur in young women in order to identify the relationship between muscle strength and bone mineral density. Method: The BMD was measured with a Dual Energy X-ray Absorptiometry and muscle strength was measured with a handgrip dynamometer and a Cybex Norm. Data were analyzed with frequencies, percentages, means, and Pearson correlation coefficients. Result: 1) Higher grip strength correlated positively with higher BMD in the forearm (r=.246, p=.007), higher low back extensor strength with higher BMD in the femur (neck, trochanter and Ward's triangle)($r=.323{\sim}.226$, $p=.003{\sim}.043$) and higher strength in the knee joint extensor with higher BMD in the lumbar spine (r=.227, p=.041), femur neck, and femur trochanter significantly ($r=.295{\sim}.226$, $p=.007{\sim}.043$). There was no significant correlation between the strength of low back extensors and BMD in the lumbar spine, now with strength of knee joint flexor and the BMD in the femur. 2) The muscle strength of each part of the body had significant positive correlations to each other part ($r=.255{\sim}.728$ $p=.021{\sim}.000$) Conclusion: The results of this study showed that with the development of a muscle there was an increased BMD of the corresponding part, and the BMD of each part was influenced by adjacent muscles. To promote the health of bones, it is important to strengthen the muscles of related bones, based on balanced development of all muscles.

This study is retrospective analysis of 31 patients treated by arthroscopically assisted ACL reconstruction, from September 1995 to September 1996. ACL reconstructions using autogenous bone patellar tendon bone (B-PT-B) were done in 18 patients, and using hamstring tendon were done in 13 patients. We used four-stranded hamstring tendon grafts and fixed the grafts using Endobutton and screw. The mean postoperative Lysholm knee score was 87.2 points in B-PT-B. group, and 89.0 points in hamstring tendon group. There were no clinically significant results between two groups in Telos test, quadriceps atrophy, Lachman test, anterior drawer test and pivot shift test, but the incidences of anterior knee pain were lower in hamstring group. Four-stranded hamstring tendon graft showed enough stability and good functional outcome similar to that of patellar tendon graft, and had an advantage of quicker return of quadriceps function and less donor site morbidity.
