We performed an advancement and medial transfer of the tibial tuberosity based on Fulkerson's principle to treat intractable anterior knee pain associated with patellofemoral maltracking diagnosed by dynamic MRI.

Between January 1998 and July 2000 twenty-two patients had 28 knees operated for anterior knee pain. There were 4 men and 18 women with a mean age of 28 years (range 18-41). Indications for surgery were [a] failure to improve after six months of physiotherapy and [b] patellofemoral maltracking evident in dynamic MRI. Mean follow-up was for 37 months (23 – 42). Knee instability score modified by Fulkerson was employed for objective and subjective assessment.

Objectively 22 (79%) knees achieved good to excellent results. Four knees (14%) had fair, and two (7%) had poor results. Excellent and very good results were seen in 20 knees. These patients were a younger age group (mean age 21 years) and had minimal degeneration (grade I-II) of the patellofemoral joints. Two patients achieved good results. One of them had moderate (grade III) and one minimal (II) arthritis. Three knees with fair results had advanced (grade IV or V) and one had moderate (grade III) arthritis. Out of two patients who had a poor result, one had advanced degeneration (grade V) that later required a patellofemoral joint resurfacing. The other was a 24 year old woman with grade II changes. She was treated by the pain therapy team.

Anterior displacement of the tuberosity in the presented study was kept to 5 mm to avoid the possible complications of wound break down. The overall length and depth of the osteotomy was also reduced to minimise risk of fracture and commence early mobilisation.

Based on our results there is a strong case of justification for Anteromedialisation of tibial tuberosity using a smaller length of osteotomy and lesser degree of anteriorisation in carefully selected patients with Patellofemoral arthralgia associated with maltracking patella.

Efficient utilisation of the trauma list is an important aspect of trauma care in the NHS. An audit of the trauma theatre time utilisation was done from April 1999 to March 2000. Ideally the first case should start at 8:30 am. However, we found that the first patient was on the operating table only by 9:40 am (mean). The main reasons for the delay were the time required for the anaesthetist to see the patient and the other staff to set up the necessary equipments. We decided to identify the first case of the trauma list the day before, so that the anaesthetist can review the patient the previous day. We felt that this would also give adequate time for the theatre staff to set up their instruments. However, this did not improve the theatre timings.

We introduced the novel idea of performing a carpal tunnel decompression at the beginning of each trauma list to make use of the redundant time without an extra financial burden to the hospital. Carpal tunnel decompression can be performed under local anaesthetic by a basic grade surgeon. This would also give time for the anaesthetist and the consultant surgeon to review the patients on the trauma list.

The theatre time utilisation was re-audited a year following the introduction of carpal tunnel release. The patient for carpal tunnel decompression was on table at 8:44 am (mean). The first trauma case was on operating table at 9:46 am (mean). Therefore, in spite of performing an additional surgery on the list, there was a delay of only 6 minutes. This simple idea has helped us to do an additional case every day with only a 6 minute delay to the trauma list.

Arthrodesis of the first metatarsophalangeal joint (MTPJ) has been recommended for various big toe deformities. We present a new technique of internal fixation for achieving dynamic compression at the first metatarso-phalangeal joint arthrodesis using memory compression staples. The memory compression staple is fabricated from equiatomic Nickel-Titanium (Ni-Ti) alloy. This alloy has a property by virtue of which it becomes easily malleable at a low temperature and reverts back to its original shape at a higher temperature. This property is known as the Shape Memory Effect. This principle is employed to provide compression at the arthrodesis site. Thirty feet were operated in 27 patients. There were 24 females and 3 males with a mean age of 61.2 years. Two memory compression staples were used at right angles to each other to achieve compression at the fusion site. The post-operative regime allowed full weight-bearing in a rigid sole shoe. A standard questionnaire was used for the subjective assessment, which included questions regarding level of pain, ambulation and patient satisfaction. Objective assessment was performed by a clinical and a radiological examination. Post-operatively there was a reduction in the pain score from 4.6 to 1.6 (p< 0.0001). Ambulation ability improved from 4 to 2.5 (p< 0.0001). There was 96.7% of radiological fusion with an average fusion time of 8.2 weeks. Patients reported 86.6% excellent to good results. The only significant post-operative complication was a single non-union.

We advocate memory compression staples for the internal fixation of the first metatarsophalangeal joint arthrodesis, which is a low profile implant, does not require post-operative cast immobilisation and has a predictable success rate comparable to previously reported methods.
