The effects of knee meniscectomy on the development of osteoarthritis in the patellofemoral joint 40 years following meniscectomy

Abstract: Most knee osteoarthritis and meniscectomy studies focus on osteoarthritis in the tibiofemoral joint and ignore the patellofemoral joint. This study aims to assess the long-term effects of total meniscectomy on the patellofemoral joint. To our knowledge, this is the only study of osteoarthritis in the patellofemoral joint following meniscectomy that extends to a 40-year follow-up period. Twenty-two patients with osteoarthritis were evaluated at a mean of 40 years post-meniscectomy using standardised weight-bearing radiographs of the operated and non-operated knees. Patellofemoral joint osteoarthritis was diagnosed by the presence of osteophytes and joint space narrowing to less than 5 mm. Kellgren and Lawrence scores were calculated from the radiographs. Patellofemoral joint osteoarthritis and tibiofemoral joint osteoarthritis were correlated with International Knee Documentation Committee scores and range of movement measurements. A significant difference was observed between the operated and non-operated knees in terms of patellofemoral joint osteophyte formation. There was a significant difference in tibiofemoral joint Kellgren and Lawrence scores, International Knee Documentation Committee scores and range of movement measurements between knees with lateral facet patellofemoral joint space of 5 mm. This study shows an association between open total meniscectomy and patellofemoral joint osteoarthritis at 40 years following surgery. There was also an association between patellofemoral joint space narrowing in the lateral facet and tibiofemoral joint osteoarthritis. Possible causes include altered biomechanical loading patterns following meniscectomy as well as global processes within the knee

Trapeziumectomy and Mini Tightrope stabilization of the first metacarpal for thumb carpometacarpal osteoarthritis: a prospective case series

Our purpose was to investigate the short-term results of trapeziumectomy and stabilization of the first metacarpal by using the TightRope© device, at a maximum follow-up of 1 year post-op. This is a novel method in treating first carpometacarpal joint osteoarthritis and an alternative to the variety of other methods that have been previously reported. We recruited 21 patients and assessed them at regular intervals, comparing pre-operative and post-operative variables. We recorded all complications during the study period. There was a statistically significant improvement in pain, hand grip and tip pinch power and functional outcome scores. Patients were very satisfied at 12 months after surgery. No significant change in thumb opposition was noted. There was subsidence of the first metacarpal at 1 year after surgery. Despite the existence of a significant number of alternative procedures, we feel that the procedure described in this paper has promising short-term results and is safe.

Rotatory subluxation of the proximal interphalangeal joint: an easily missed diagnosis

We present a case of volar rotatory subluxation of index finger proximal interphalangeal joint (PIPJ) following a skiing accident. The injury was initially perceived to be a central slip rupture and treatment was directed as such. After the initial delay in the diagnosis, the patient underwent surgery during which his radial collateral ligament was found to be avulsed from the proximal origin, the radial lateral band palmarly subluxed and was interposed in the joint space. This structure was also adhered to the uninjured volar plate.PIPJ volar rotatory subluxation could be readily missed in the acute setting. Without surgery, the functional outcome could be mediocre and to the patient’s detriment.</jats:p

Proximal Humerus Fractures in Children: Experience from a Central London Paediatric Orthopaedic Service

Objective: Proximal humeral fractures are commonly observed in children who sustain falls whilst running, or from heights. Appropriate and correct treatment is key in order to avoid limb length discrepancy and functional deficiencies. Current treatment methods include non-operative management such as collar and cuff immobilisation, and operative methods such as elastic stable intramedullary nails or Kirschner wires. This paper aims to present the demographics of this patient population and our experience in managing patients with proximal humerus fractures in an urban tertiary referral centre. Method: We assessed 41 cases across two sites in central London, identified via hospital electronic notes and our radiology digital system. We analysed patient demographics, mechanism of injury, time to discharge from orthopaedic services taking into account radiological and clinical union, and the treatment methods utilised. Results: The mean age of the cohort was 8.6 years old. 70% of the injuries were due to falls and 85% of cases were treated without an operation. The mean time to discharge from our service following radiological and clinical union was 46 days (9 – 161 days). Mean radiological and clinical union were 21.8 and 36.2 days respectively. Conclusion: These results support a non-operative approach, especially in cases with patients under 10 years of age. Surgery should only be undertaken in patients who have severe displacement and who have failed attempts at closed reduction. We would advocate a similar approach in institutions dealing with a comparable population of patients, as long as there are provisions for referral of more complex cases that require surgical stabilisation. </jats:sec
