Engineering requirements for a haptic simulator for knee arthroscopy training.

Abstract

This paper describes the initial development of an innovative haptic device that will be integrated into an existing virtual reality training system for knee arthroscopy. The resulting system will be called WISHKATS (Warwick, Imperial, Sheffield Knee Arthroscopy Training System). This haptic device will enable the trainee to feel realistic forces on the probing tool and will work together with software, which will simulate tissue deformation. The proposed haptic system is a compact, multi-degree of freedom, motorised mechanism with force sensors, and will be used to simulate the diagnostic aspects of knee arthroscopy. There are a number of problems associated with the development of a suitable haptic system and this paper explores the engineering requirements of such a device.

Arthroscopic or conservative treatment of degenerative medial meniscal tears: a prospective randomised trial.

In this prospective randomised study two treatments after non-traumatic medial meniscal tear diagnosed with radiological examination and magnetic resonance imaging were compared; arthroscopic partial meniscectomy followed by supervised exercise or supervised exercise alone. The aim was to evaluate knee function and physical activity. Ninety patients (mean age 56 years) were evaluated using the Knee Injury and Osteoarthritis Outcome Score, the Lysholm Knee Scoring Scale, the Tegner Activity Scale and a Visual Analogue Scale for knee pain prior to the intervention, after 8 weeks of exercise and after 6 months. According to the outcome scores arthroscopic partial medial meniscectomy combined with exercise did not lead to greater improvement than exercise alone. After the intervention both groups reported decreased knee pain, improved knee function and a high satisfaction (P<0.0001). Forty-one per cent of the patients returned to their pre-injury activity level after 6 months. In conclusion, when evaluated with outcome scores, arthroscopic partial medial meniscectomy followed by supervised exercise was not superior to supervised exercise alone in terms of reduced knee pain, improved knee function and improved quality of life.

The "purse-string" technique: an arthroscopic technique for stabilization of anteroinferior instability of the shoulder with early and medium-term results.

PURPOSE: We report the early and midterm results of the "purse-string" technique, a simple, new arthroscopic technique for stabilization of anteroinferior instability of the glenohumeral joint that addresses both the Bankart lesion and capsular stretching. METHODS: The patients comprised 36 individuals (37 shoulders), with a mean age of 26 years, who had recurrent anteroinferior post-traumatic instability as a result of a traumatic Bankart lesion. They had sustained a mean of 5 dislocations per shoulder (range, 1 to 11). The cohort included 5 professional and 6 semiprofessional athletes, all of whom were involved in collision or overhead sports. A purse-string suture anchor at the 4-o'clock position was used to ensure a purse-string effect in tightening the capsule in the inferior-superior plane and creation of anterior glenoid bumper. All of the patients were assessed by an independent investigator (T.M.) at a mean of 36 months (range, 27 to 87 months) after surgery. RESULTS: Postoperatively, the mean Rowe score was 93 (range, 55 to 100), the mean Walch-Duplay score was 93 (range, 70 to 100), and the mean Constant score was 97 (range, 77 to 100). Of the patients, 97% returned to the same sport that they had played before injury. Furthermore, 66% of patients returned to their preinjury level of sports, and all of the professional athletes resumed full activities. One patient continued to have symptoms of instability, and one patient had a further dislocation after a new traumatic event. CONCLUSIONS: The early and medium-term results obtained are very encouraging, with a rate of failure of only 5.4%, a high level of return to preinjury sporting activities (with 97% of patients returning to the same sport and 66% returning to their preinjury level of sports), and a high patient satisfaction rate (with excellent or good results in 94% of patients). LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Biomechanical fixation in arthroscopic rotator cuff repair.

Rotator cuff repair remains a challenging and rapidly evolving field. Several recent studies have shown that arthroscopic repair yields functional results similar to those of mini-open and open procedures, with all of the benefits of minimally invasive surgery. However, the "best" repair construct remains relatively unknown, with wide variations in surgeon preference and conflicting evidence in the literature. The most recent developments in basic science, suture and suture anchor technology, and innovative prospects for arthroscopic rotator cuff repair are reviewed.
