Barak Haviv, John O'Donnell
Sports Medicine, Arthroscopy, Rehabilitation, Therapy & Technology , 2010, DOI: 10.1186/1758-2555-2-18
Abstract: Retrospective clinical seriesFollow-up data and surgical reports were retrieved from 564 records of osteoarthritic patients that have had hip arthroscopy between the years 2002 to 2009 with a mean follow-up time of 3.2 years (range, 1-6.4 years). The time interval between the first hip arthroscopy to THA was modelled as a function of patient age; level of cartilage damage; procedures performed and repeated arthroscopies with the use of multivariate regression analysis.Ninety (16%) of all participants eventually required THA. The awaiting time from the first arthroscopy to a hip replacement was found to be longer in patients younger than 55 years and in a milder osteoarthritic stage. Patients that experienced repeated hip scopes had a longer time to THA than those with only a single procedure. Procedures performed concomitant with debridement and lavage did not affect the time interval to THA.In our series of arthroscopic treatment of hip osteoarthritis, 16% required THA over a period of 7 years. Factors that influence the time to arthroplasty were age, degree of osteoarthritis and recurrent procedures.Currently there are various options to treat osteoarthritis (OA) and certain evidence based recommendations have been developed [1,2]. According to these propositions in young adults with symptomatic OA one should consider a joint preserving surgical procedure while replacement is usually reserved for older patients. With the evolution of hip arthroscopy, it has been used as joint preserving surgery for OA among various other indications, yet there are only a few reports on its efficacy in treating OA [3-8]. In a controlled trial involving patients with osteoarthritis of the knee [9], the outcomes after arthroscopic lavage or arthroscopic debridement were no better than those after a placebo procedure. There are, however, times when arthroscopic treatment of the osteoarthritic joint can be of benefit, particularly in that patient who has relatively mild to moderate ost

Abstract: Thirty consecutive patients who met inclusion and exclusion criteria underwent arthroscopic debridement by a single surgeon and concomitant delivery of 6 ml/90 mg HA (Orthovisc?). These patients were evaluated preoperatively, at 6 weeks, 3 and 6 months post-operatively. Evaluations consisted of WOMAC pain score, SF-36 Physical Component Summary (PCS) score and complications.No complications occurred during this study. Pre-op average WOMAC pain score was 6.8 +/- 3.5 (n = 30) with a reduction to 3.4 +/- 3.1 at 6 weeks (n = 27). Final average WOMAC pain score improved to 3.2 +/- 3.8 at six months (n = 23). No patients had deterioration of the WOMAC pain score. Mean pre-operative SF-36 PCS score was 39.0 +/- 10.4 with SF-36 PCS score of the bottom 25th percentile at 29.9 (n = 30). Post procedure and HA delivery, mean PCS score at 6 weeks improved to 43.7 +/- 8.0 with the bottom 25th percentile at 37.5 (n = 27). At 6 months, mean PCS score was 48.0 +/- 9.8 with the bottom 25th percentile improved to 45.8 (n = 23).The results show that concomitant delivery of high molecular weight hyaluronan (Orthovisc? – 6 ml/90 mg) is safe when given at the time of arthroscopic debridement of the osteoarthritic knee. By delivering HA (Orthovisc?) at the time of the arthroscopic debridement, there may be a decreased risk of joint infection and/or injection site pain. Furthermore, the combination of both procedures show efficacy in reducing WOMAC pain scores and improving SF-36 PCS scores over a six month period.Osteoarthritis (OA) is the most prevalent musculoskeletal disorder and the leading cause of disability in adults over the age 45 years [1-3]. OA of the knee is extremely common, with some studies showing that OA of the knee occurs in at least 30% of people after the age of 50 years, and in 80% of people older than 75 years [4,5]. Of the patients with OA, over 80% will have limitation of movement and greater than 25% can not perform their activities of daily living [3]. Traditional

Abstract: Objective: Osteoarthritis is the most seen type of arthritis and forms more than 6% of all symptomatic knee diseases. A lot of treament modalities are used and the treatment algorithm acts from conservative precedures to surgical procedures. Material and Methods: Fourty patients who had symptomatic primary osteoarthritis for ACR (American College of Rheumatology) criteria, who were in mild and moderate stages for IKDC (International Knee Documentation Committee) and who were symptomatic in spite of at least six months of treatment were integrated to the study. The quality of life and functional evaluation of patients are done before and at least six months after the surgery by SF-36 quality of life and Lysholm scores. All patients are evaluated with patient pleasure scala at their last visits. Results: The increase of mean Lysholm knee score after arthroscopic debridement was statistically significiant (p<0.01). The increase of total SF-36 score and short physical health score at the last visit after arthroscopic debridement was statistically significiant (p<0.05). The mean score for patient pleasure scala was 6.6±2.24. Conclusion: Arthroscopic debridement can be used as an effective treatment method for patients who have mild to moderate gonarthrosis and mechanical symptoms which is resistant to the medical treatment.

Abstract: Background The effectiveness of arthroscopic treatment for osteoarthritic knee is a controversy. This study presents the technique of a novel concept of arthroscopic procedure and investigates its clinical outcome. Method An arthroscopic procedure targeted on elimination of focal abrasion phenomenon and regaining soft tissue balance around patello-femoral joint was applied to treat osteoarthritis knees. Five hundred and seventy-one knees of 367 patients with osteoarthritis received this procedure. There were 70 (19%) male and 297 (81%) female and the mean age was 60 years (SD 10). The Knee Society score (KSS) and the knee injury and osteoarthritis outcome score (KOOS) were used for subjective outcome study. The roentgenographic changes of femoral-tibial angle and joint space width were evaluated for objective outcomes. The mean follow-up period was 38 months (SD 3). Results There were 505 knees in 326 patients available with more than 3 years follow-up and the mean follow-up period was 38 months (SD 3). The subjective satisfactory rate for the whole series was 85.5%. For 134 knees with comprehensive follow-up evaluation, the KSS and all subscales of the KOOS improved statistically. The femoral-tibial angle improved from 1.57 degrees (SD 3.92) to 1.93 degrees (SD 4.12) (mean difference: 0.35, SD 0.17). The joint space width increased from 2.02 millimeters (SD 1.24) to 2.17 millimeters (SD 1.17) (mean difference: 0.13, SD 0.05). The degeneration process of the medial compartment was found being reversed in 82.1% of these knees by radiographic evaluation. Conclusions Based on these observations arthroscopic cartilage regeneration facilitating procedure is an effective treatment for osteoarthritis of the knee joint and can be expected to satisfy the majority of patients and reverse the degenerative process of their knees.

Abstract: Objective: We evaluated clinical results of intra-articular injection of hyaluronic acid and peroral Vitamin E treatment after arthroscopic debridement in patients with knee osteoarthritis who got no cure with medical treatment previously. Materials and Methods: A total of 44 patients with knee pain, who were diagnosed as having knee osteoarthritis according to the American College of Rheumatology criteria, were included in this study. The subjects were randomly divided into 3 groups after arthroscopic debridement: Group S was given intra-articular Hylan G-F 20 treatment; Group S+E - intraarticular Hylan G-F 20 treatment plus oral vitamin E; and Group C underwent only arthroscopic debridement. Pain, stiffness and functional capacity scores were evaluated preoperatively and 6 and 12 months postoperatively according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results: In all groups, 6- and 12-month postoperative WOMAC scores were lesser than the preoperative ones. The WOMAC scores at 6 and 12 months were statistically lower in the S+E and S groups than in the group C (p<0.05). The S+E group demonstrated better results in terms of improvement in symptoms than the S-group at 6 and 12 months postoperatively (p<0.05). Conclusion: We believe that arthroscopic debridement is beneficial in suitable knee osteoarthritis cases and vitamin E and intra-articular hyaluronic acid may reduce the symptoms of knee osteoarthritis.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0078953
Abstract: Arthroscopic lavage and arthrocentesis, performed with different inner-diameter lavage needles, are the current minimally invasive techniques used in temporomandibular joint disc displacement (TMJ-DD) for pain reduction and functional improvement. In the current study, we aimed to explore the biomechanical influence and explain the diverse clinical outcomes of these two approaches with computational fluid dynamics. Data was retrospectively analyzed from 78 cases that had undergone arthroscopic lavage or arthrocentesis for TMJ-DD from 2002 to 2010. Four types of finite volume models, featuring irrigation needles of different diameters, were constructed based on computed tomography images. We investigated the flow pattern and pressure distribution of lavage fluid secondary to caliber-varying needles. Our results demonstrated that the size of outflow portal was the critical factor in determining irrigated flow rate, with a larger inflow portal and a smaller outflow portal leading to higher intra-articular pressure. This was consistent with clinical data suggesting that increasing the mouth opening and maximal contra-lateral movement led to better outcomes following arthroscopic lavage. The findings of this study could be useful for choosing the lavage apparatus according to the main complaint of pain, or limited mouth opening, and examination of joint movements.

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).
